+### A note on Windows Defender warnings
+
+Windows Defender sometimes flags the Windows build with a generic
+machine-learning detection such as `Trojan:Win32/Wacatac!ml` (#621). This is
+a known false positive: the exe is the official LÖVE runtime with the game
+archive appended (the standard way LÖVE games ship), and Defender's
+heuristics distrust unsigned executables with appended data. Every release
+publishes SHA-256 checksums (`sha256sums.txt`) so you can verify your
+download, and you can confirm a flagged file yourself on
+[VirusTotal](https://www.virustotal.com), where these builds come back clean
+on every engine except Defender's heuristic. False positives are reported to
+Microsoft as they come up.

+offset for fonts whose strokes read too light, and `tiles`, the

+list when a multi-character charmap sequence is meant.

 cancels it, so it is hard to hit by accident -- including on the on-screen
 touch controls, where it would take four fingers held on four separate
 controls.
+
+## Controls rebinding (CONTROLS screen)
+
+OPTIONS -> CONTROLS lists every Game Boy button with its current keyboard
+key and controller button side by side (Z/A). Press A on a row, then press
+and release the key or pad button you want; the rebind commits on the
+release. If that input already belongs to another row, the two rows swap,
+so no button is ever stranded without an input and no input ever serves
+two buttons. Holding a second key or pad button while the first is still
+down backs out of the capture without touching a keyboard; Escape still
+cancels too. SELECT clears one row back to its default, and START resets
+every binding after a confirmation.
+
+Controllers a system has no mapping for (common on Linux handhelds and
+off-brand pads) report bare button numbers rather than names. Those are
+rebindable on the same screen and show up as JOY1, JOY2 and so on in the
+controller column. Recognized controllers are read only through their
+named buttons, so a rebind on those is never shadowed by the factory
+layout underneath it.
+
+## Mod profiles (#593)
+
+The mod manager's PROFILES tab holds named setups. A profile remembers which
+mods are on, every mod's own options, and which save slot each game version
+plays, so swapping profiles swaps the whole playthrough and not just the mod
+list. The setup that existed before profiles shipped becomes PROFILE 1 the
+first time the manager opens.
+
+EXPORT.. writes the selected profile to `profiles/<NAME>.g1rmodlist` in the
+save directory; drop a `.g1rmodlist` someone shared into that folder and
+IMPORT.. adds it. Imported profiles never overwrite an existing one (a name
+clash gets a number). Mods the shared profile names but that are not installed
+are reported when the profile is applied; installing them is still a manual
+trip through the mods list or Find Mods.
+
+## Windows: no console windows on launcher actions
+
+Checking for updates, browsing a mod index, adding a mod repo, installing a
+mod and picking a ROM all run a host tool (curl, PowerShell) in a child
+process. On Windows those children used to each open their own console
+window, so a session could end up buried under half a dozen of them. The
+game now claims one console for itself at boot and hides it; the children
+inherit that invisible console and nothing pops up. Nothing else changes:
+file pickers are ordinary desktop dialogs and still appear normally, and a
+run started from a terminal (`lovec.exe`, what `scripts\run.ps1` prefers)
+keeps its terminal and its printed output. Set `POKEPORT_CONSOLE=1` to opt
+out.
+
+## A faster, higher-contrast launcher
+
+The launcher and the save editor were rebuilt on one small immediate-mode UI
+kit (`src/ui/kit/`), replacing the vendored FlexLove layout engine. The
+visible result is that the launcher is quick: building and drawing a frame
+went from about 9 ms to under 1 ms on the same machine and the same data, at
+every window size, so the window keeps up with the pointer instead of
+trailing it. Measure it yourself with `POKEPORT_LAUNCHER_PROF=200 love .`.
+
+**Nothing blocks the window any more.** Fetching a mod index, checking a mod
+for updates, listing versions, downloading an install and pulling thumbnails
+all run on background threads. Opening FIND MODS on a cold cache used to
+freeze the launcher for as long as the server took -- often minutes, with no
+indication anything was happening. Mod indexes are now also fetched at boot,
+so the tab is usually already populated by the time you reach it.
+
+**Anything you wait on says so.** Every operation that takes time raises a
+loading panel with a spinner or a progress bar that cannot be clicked around
+or dismissed, so a half-finished install can never be interrupted by a stray
+click. Work that only affects one row (a mod's update check) shows a small
+spinner on that row instead and leaves the rest of the list usable.
+
+**Lists page instead of scrolling.** Mods, Find Mods, save slots, settings,
+release notes and the version list all show a fixed number of rows with a
+pager underneath, and the number of rows comes from the window height -- a
+tall window shows more, a phone shows fewer. A long list costs exactly what a
+short one does. The mouse wheel turns pages.
+
+**Updates live in the top right.** The in-app updater moved next to the
+settings gear and pulses when an update is waiting, instead of sitting in a
+banner at the bottom of the page that you had to scroll to notice. Checking
+for updates from there shows a loader like everything else.
+
+**The look.** Black background, white outlines, no gradients or glows, and
+buttons that are solid colour-coded keys: green commits, blue navigates, red
+destroys, yellow wants attention. The three game tabs keep their red, blue
+and gold cartridge colours. Everything is about a third larger than before.
+The save editor follows the same theme, and adding an item there is now a
+searchable pop-up like adding a Pokemon, rather than a cramped list wedged
+into the tab.
+
+**Reset rebinds.** Input rebinds are additive, so there was no in-game way to
+undo one. A RESET REBINDS row in Settings, and a matching button under Touch
+Controls on each game tab, restore the stock keyboard, gamepad and touch
+layout. Both ask twice.
+
+## Launch options: boot straight into a game
+
+`love . --game red` skips the launcher and starts that game; `--slot <id or
+number>` picks the save slot to load, and `--launcher` forces the launcher
+anyway. `POKEPORT_GAME` / `POKEPORT_SLOT` do the same for shortcuts that can
+only pass environment variables. This is for one-click entries: a desktop
+shortcut per game, a Steam entry, or a handheld frontend. Asking for a game
+whose ROM has not been imported opens the launcher on that game's tab rather
+than failing.

+# RFC 0001 — Port Yellow's `IsSurfingPikachuInParty` surf sprite
+
+## Status
+
+Proposed. Engine: `Player.lua`, `FieldDefaults.lua`,
+`OverworldController.lua`, `RomExtractor.lua`, `PaletteFX.lua`. Tools:
+`build_rom_data.py`, `extract/sprites.py`, `make_rom_manifest.py`,
+`make_yellow_manifest.py`. Tests: `parity_surfing_pikachu_sprite.lua`,
+`mod_world_tests.lua`.
+
+**Regeneration required.** The manifest and sprite sheet update by
+re-running `make_yellow_manifest.py` against a `pret/pokeyellow`
+checkout, then re-importing the Yellow ROM.
+
+## Motivation
+
+Yellow's `IsSurfingPikachuInParty` + `LoadSurfingPlayerSpriteGraphics2`
+(`home/map_objects.asm`, `home/overworld.asm`) swap the player's
+overworld sheet to `SurfingPikachuSprite` (`gfx/sprites/
+surfing_pikachu.2bpp`, a 16×96 walk sheet — not the minigame sheets)
+when the party mon that knows SURF is a Pikachu. The recomp misses this
+in two places:
+
+1. **Extraction.** `SurfingPikachuSprite` is not in
+   `SpriteSheetPointerTable` — loaded by its own `ld de,` like
+   `RedBikeSprite`. The extractor never sees it, and the symbol is not
+   in the Yellow manifest.
+2. **Engine rule.** `field.playerSprites.surf` is one static
+   (`SPRITE_SEEL`), cached at boot. No seam for "swap when the SURF-mon
+   is a Pikachu."
+
+## The decision it extends
+
+No prior D-number. Extends the surf-field-move port in
+`docs/behavior-porting-notes.md` (the `IsSurfingAllowed` exact port)
+with the player-sprite swap vanilla runs alongside it.
+
+## The exact API delta
+
+Backward-compatible, additive-only.
+
+### `field.playerSprites.surfPikachu`
+
+New optional key alongside `walk`/`surf`/`bike`/`fly`, defaults to
+`SPRITE_SURFING_PIKACHU`. Guarded in `Player.new` so before extraction
+lands the ride keeps the Seel — no plain on-water Pikachu.
+
+### `Player.surfPikachuSprite`
+
+`Player.new` builds a second `SpriteRenderer` when the field resolves.
+`pose()` picks it when `surfing and surfingPikachu`.
+
+### `Player.surfingPikachu` (runtime)
+
+Runtime-only boolean (not persisted); re-derived so a party change
+between save and load is honored.
+
+### `OverworldState:syncSurfingPikachu()`
+
+Sets `player.surfingPikachu` from `partyKnows("SURF")`. Called at every
+surf-state toggle: trySurf, dismount, flyTo, beginTeleportOut,
+warpToHealPoint, forced-surf tile, setMap boot-restore.
+
+### Importer — `SPRITE_SURFING_PIKACHU`
+
+`make_yellow_manifest.py` adds `SurfingPikachuSprite` to
+`YELLOW_EXTRA_SYMBOLS`. `make_rom_manifest.py`'s `sprite_metadata()`
+gains a `surfPikachu` entry (guarded, so Red/Blue unchanged).
+`RomExtractor.extractSprites` + `build_rom_data.py` + `extract/sprites.py`
+each gain a parallel extract mirroring `RedBikeSprite`.
+
+### `PaletteFX.spriteObp`
+
+`SurfingPikachuSprite` joins `RedBikeSprite` in the no-bracket-index
+special case, wearing the player's OBP palette so it colors in GBC mode.
+
+## Migration note for existing mods
+
+**Nothing.** `surf` still defaults to `SPRITE_SEEL`; `surfPikachu`
+only resolves on a Yellow import after regeneration. No manifest or
+`mod.save` shape changes. An eligibility hook that swaps a rental
+SURF-mon still drives the sprite pick via `partyKnows`.
+
+## Parity tests
+
+- **No-mod** (`mod_world_tests.lua`): `surf == "SPRITE_SEEL"`,
+  `surfPikachu == "SPRITE_SURFING_PIKACHU"` seeded at boot. The 19229-check
+  `world & maps v2` suite stays green.
+- **Mod-API** (`parity_surfing_pikachu_sprite.lua`): `syncSurfingPikachu`
+  + `Player:pose` across four party shapes (12/12). The existing
+  `parity_cinnabar_east_surf.lua` (24/24) stays green.
+
+## Deprecation etiquette
+
+Nothing deprecated. Additive: a new `field.playerSprites` key, a new
+runtime flag, a new engine method, a new sprite id.

+# Build the Nintendo Switch NRO — contributor guide
+
+Want to play a release build instead? Download the SD-ready zip and extract it
+at your microSD root — see [switch-install.md](switch-install.md).
+
+This guide is for contributors who build Gen1Recomp for Switch from source.
+Hardware evidence, MTP operator loops, and deeper notes live in
+[switch-development.md](switch-development.md).
+
+> Releases ship `gen1recomp-*-switch.zip` (SD tree under `switch/gen1recomp/`;
+> issue [#531](https://github.com/bryanthaboi/gen1recomp/issues/531)). Hardware
+> evidence: **OLED** (author) and **V1 boot** (community). See
+> [switch-development.md](switch-development.md) for known limitations.
+
+---
+
+## Prerequisites by OS
+
+All packaging entrypoints are **bash**. On Windows, use Git Bash, MSYS2, or
+WSL — not cmd.exe or PowerShell (AD-008).
+
+### macOS / Linux
+
+1. Install [devkitPro pacman](https://devkitpro.org/wiki/devkitPro_pacman).
+2. Install Switch tools:
+
+   ```sh
+   sudo dkp-pacman -S switch-dev
+   ```
+
+3. Ensure `nacptool` and `elf2nro` are on `PATH` (or under
+   `$DEVKITPRO/tools/bin` — the fused script prepends that when set).
+
+**Optional:** Install [Docker](https://docs.docker.com/get-docker/) so fused
+builds can fall back to the pinned image when native tools are missing.
+
+### Windows (Git Bash / MSYS2 / WSL)
+
+1. Use a bash environment:
+   - **MSYS2** with the [devkitPro](https://devkitpro.org/wiki/devkitPro_pacman)
+     packages (preferred for native `nacptool`/`elf2nro`), or
+   - **WSL** (Ubuntu/etc.) with the Linux pacman flow above, or
+   - **Git Bash** for `--fetch` / `--loose`; for `--fused` prefer MSYS2 or
+     WSL if Docker bind-mounts from Git Bash paths misbehave.
+2. Install `switch-dev` (or rely on Docker fallback — see below).
+3. Do **not** expect `scripts/build_switch.sh` to run under cmd/PowerShell.
+
+### What you must install yourself
+
+| You install | Script does **not** install |
+| ----------- | --------------------------- |
+| bash, git, zip tooling the repo already expects | — |
+| `dkp-pacman` + `switch-dev` (native fused) | `dkp-pacman -S …` |
+| Docker (optional fused fallback) | Docker Engine |
+| A legal `.gb` ROM (to play) | Any ROM or game data |
+
+---
+
+## Mode glossary
+
+`scripts/build_switch.sh` supports three modes (combinable as noted):
+
+| Mode | What it does |
+| ---- | ------------ |
+| `--fetch` | Downloads pinned **love.nro** + **love.elf** into `.bazinga/love-nx/11.5-nx1/` and verifies SHA-256 against `scripts/switch/love-nx-11.5-nx1.sha256`. |
+| `--loose` | Packs `game.love`, copies pinned `love.nro` → `dist/switch/loose/` as `gen1recomp.nro` + `game.love` side by side. Needs the pin. |
+| `--fused` | Builds `dist/switch/gen1recomp-<ver>-switch.nro` (game in romfs) via `nacptool` + `elf2nro`, then packs `dist/switch/gen1recomp-<ver>-switch.zip` (SD-ready tree). Needs the pin + toolchain (native or Docker). GitHub Releases publish the **zip only**. |
+
+Rules:
+
+- `--fetch` alone is fine; combine as `--fetch --loose` or `--fetch --fused`.
+- `--loose` and `--fused` are **XOR** — pick one packaging path per run.
+- `--version X.Y.Z` sets the NACP / filename version (defaults to short git SHA).
+
+### What `--fetch` downloads
+
+Only the two pinned love-nx release assets (`love.nro`, `love.elf`). It does
+**not** install:
+
+- devkitPro / `dkp-pacman` / `switch-dev`
+- Docker
+- ROMs, saves, or mods
+
+---
+
+## Native tools, then Docker
+
+Fused packaging (`scripts/switch/build_fused.sh`):
+
+1. Prefer native `nacptool` + `elf2nro` on `PATH` (or `$DEVKITPRO/tools/bin`).
+2. Else fall back to Docker using:
+   - `GEN1_DKP_IMAGE` if set, otherwise
+   - the image named in `scripts/switch/dkp-docker.image` (default
+     `devkitpro/devkita64:latest`).
+
+If neither native tools nor Docker work, the script exits non-zero with
+macOS / Linux / Windows / Docker hints and a pointer to this doc.
+
+---
+
+## Example commands
+
+From the repo root:
+
+```sh
+# Download pinned love-nx only
+scripts/build_switch.sh --fetch
+
+# Loose pair for iteration (fetch + assemble)
+scripts/build_switch.sh --fetch --loose
+
+# Single fused NRO + SD-ready zip for a release-like artifact
+scripts/build_switch.sh --fetch --fused --version 0.2.0
+```
+
+Outputs land under `dist/switch/` (and `dist/switch/loose/` for loose mode).
+The fused path also writes `gen1recomp-<ver>-switch.nro.sha256` and
+`gen1recomp-<ver>-switch.zip` (+ `.sha256` sidecar for the zip).
+
+Offline packaging smoke (no network, no nacptool required):
+
+```sh
+bash scripts/switch/selftest_build_switch.sh
+bash scripts/switch/verify_payload.sh --self-test
+```
+
+---
+
+## CI and release
+
+Switch packaging has three automated surfaces (same policy as AD-010):
+
+### Path-gated PR / push CI (`.github/workflows/ci.yml`)
+
+When a change touches Switch packaging / Switch docs / NX runtime paths
+(`scripts/build_switch.sh`, `scripts/switch/**`, `docs/switch-*.md`,
+`tests/switch_ci_workflows_test.lua`, `tests/switch_transfer_docs_test.lua`,
+the NX runtime modules `src/core/NxAssetOverlay.lua`, `src/core/Platform.lua`,
+`src/core/GameVersion.lua`, `src/import/CacheFs.lua`, the NX engine suites
+`tests/engine/assets_version_fallback_test.lua`,
+`tests/engine/nx_generated_guard_test.lua`,
+`tests/engine/nx_yellow_boot_test.lua`,
+`tests/engine/switch_diagnostics_test.lua`, `tests/engine/platform_nx_*`,
+or the Switch-related workflow YAML), CI runs:
+
+1. **Offline selftest** on `ubuntu-latest` (forks **and** the canonical repo):
+   `scripts/switch/selftest_build_switch.sh`,
+   `scripts/switch/verify_payload.sh --self-test`,
+   `luajit tests/switch_ci_workflows_test.lua`,
+   `luajit tests/switch_transfer_docs_test.lua`, and the NX engine suites
+   headlessly (`luajit tests/engine/assets_version_fallback_test.lua`,
+   `luajit tests/engine/nx_generated_guard_test.lua`,
+   `luajit tests/engine/nx_yellow_boot_test.lua`).
+2. **Fused NRO build** only on the **canonical** repository
+   (`bryanthaboi/gen1recomp`), on the self-hosted Mac runner
+   (`scripts/build_switch.sh --fetch --fused`), and only when the workflow
+   head is that repo (same-repo push/PR). **Fork repository** CI never runs
+   fused. **Fork → canonical PRs** also skip Switch fused (offline selftest
+   still runs) so untrusted head code is not executed on the self-hosted Mac;
+   iOS device build eligibility is unchanged. Fused also waits for a successful
+   offline selftest before starting on the Mac runner.
+3. On successful PR fused builds, a follow-up workflow posts a PR comment
+   linking the Actions artifact named `gen1recomp-switch-nro`
+   (comment tag `switch-build-result`; see
+   `.github/workflows/switch-artifact-comment.yml`).
+
+Unrelated PRs do not burn the self-hosted Mac on Switch packaging.
+
+### Release hard-fail (`.github/workflows/release.yml`)
+
+GitHub Releases always build Switch on the same self-hosted Mac runner as the
+other platforms — this is a **hard gate** (no `continue-on-error`):
+
+```sh
+scripts/build_switch.sh --fetch --fused --version "<release version>"
+```
+
+A Switch packaging failure fails the entire release job. The release asset is
+`gen1recomp-<ver>-switch.zip` (SD-ready); the versioned `.nro` stays under
+`dist/switch/` for the packer and for PR CI artifacts.
+
+### Runner provisioning
+
+The self-hosted Mac runner must have **native switch-tools** (`nacptool` /
+`elf2nro`) **and/or Docker** available. CI and release do not silently run
+`dkp-pacman -S`; keep the runner image/host provisioned per this guide.
+
+---
+
+## Limitations / non-goals
+
+These scripts and this guide do **not**:
+
+- Push files to the console (no automated MTP / FTP / SD scripting)
+- Bundle or download any Pokémon ROM
+- Install `dkp-pacman` / `switch-dev` for you
+- Provide `nxlink` / netloader deploy (deferred — see [switch-transfer.md](switch-transfer.md))
+- Validate **Applet Mode** — use title override (hold **R**) for full memory
+
+Player install steps: [switch-install.md](switch-install.md).  
+Manual transfer (MTP / SD / FTP, macOS / Linux / Windows):
+[switch-transfer.md](switch-transfer.md).  
+Hardware depth and evidence: [switch-development.md](switch-development.md),
+[switch-hardware-evidence.md](switch-hardware-evidence.md).

+### What landed
+
+- Detect `NX` via `src/core/Platform.lua` without reusing Android flags
+- Writable ROM inbox under `getSaveDirectory()/imports/` + per-tab “Scan again” (SHA-1 match for the open game)
+- Joy-Con / gamepad mapping shared by launcher and gameplay (Nintendo A/B UX on NX)
+- Launcher L/R tab switch; gameplay L/R game-speed cycle; Select+face display chords
+- Focus loss / joystick reconnect recovery; opt-in `switch-debug.txt` diagnostics
+- Loose assemble + fused NRO build scripts (`scripts/build_switch.sh`, `scripts/switch/*`)
+- Payload gates so ROM / generated cache / saves never enter `game.love`
+- Community mod zip inbox at `imports/mods/` (rescan installs; FIND MODS stays network-gated)
+- Raw `.sav` inbox at `imports/saves/{red,blue,yellow}/` (**Import save** rescan) + export pull path `exports/{red,blue,yellow}/` (MTP hint; no openURL)
+- Hardware evidence for Phase 0 probe, ROM import, naming A/B, save/suspend, fused NRO — see `docs/switch-hardware-evidence.md`
+- Path-gated CI selftest + canonical fused PR artifact; release Switch hard-fail
+- Save editor pad/touch input (virtual cursor, A click, B close) — see `tools/save-editor/README.md`
+- Dynamic display size on NX only: handheld **1280×720**, docked/TV **1920×1080** (`src/core/NxDisplay.lua` + resizable conf so love-nx SDL can follow dock/undock at runtime)
+
+### Known gaps / welcome contributions
+
+- Docked vs handheld soak (≥30 min) and Lite coverage — resolution switch is implemented; long soak still welcome
+- Switch Lite and fuller Pro Controller / third-party pad matrices
+- Applet Mode remains unsupported by design (title override required)
+- `nxlink` / netloader contrib fast-loop (deferred — see [switch-transfer.md](switch-transfer.md))
+
+Transfer runbooks for Linux/Windows (and SD/FTP alternatives) are in
+[switch-transfer.md](switch-transfer.md). Community mod zip install OLED smoke
+is **pass** — see NXMOD-12 in [switch-hardware-evidence.md](switch-hardware-evidence.md).
+
+## Design references (Dusklight)
+
+This work borrowed method — not the native stack — from the [Dusklight Switch port](https://github.com/HayatoG/dusklight/tree/main/platforms/switch), especially [`LESSONS_AND_REUSE.md`](https://github.com/HayatoG/dusklight/blob/main/platforms/switch/LESSONS_AND_REUSE.md):
+
+| Dusklight lesson | How Gen1Recomp applied it |
+| ---------------- | ------------------------- |
+| Emulators hide Tegra failures | Gate milestones on **real OLED hardware**, not Ryujinx/Yuzu alone |
+| Prove the lower layer first | `tools/switch-probe` before full launcher |
+| Know which binary ran | Embedded `build-info.json` (commit / love-nx tag) |
+| Cap continuous logs | Opt-in diagnostics, ≤1 Hz flush; Lua error log rotation |
+| Crash symbolization needs the exact ELF | Keep pinned `love.elf` with the NRO under test |
+| Full memory matters | Title override; Applet Mode is not the validation path |
+| Do not treat SD FS like desktop POSIX | Lua stays on `love.filesystem`; inbox + MTP for user files |
+| Isolate platform code | Capability module instead of Android flag overload |
+| NVK / WSI / `audren` stacks | **Not** copied — love-nx already supplies video/audio/input/FS |
+
+The packaging goal matches Dusklight’s **single self-contained `.nro`**; contributor transfer stays multi-host (not Mac-only).
+
+## Known limitations (read before reviewing)
+
+1. **Transfer is manual and multi-method.** Runtime only needs files under the LÖVE save directory / NRO install folder. Use MTP, direct SD, or FTP per [switch-transfer.md](switch-transfer.md). macOS + OpenMTP is a documented example for OLED evidence — not “Switch requires a Mac.”
+2. **Deploy is manual.** There is no automated push to the console and no `nxlink` path yet. Operators build locally, transfer files, then title-override launch.
+3. **Hardware coverage.** Author P0/P1 pass rows were recorded on one Switch OLED; Switch V1 boot was confirmed independently. Treat Lite, docked soak, and other hosts as unknown until someone re-runs the checklist.
+4. **No ROM/save/mod zip bytes in git.** Legal dumps and third-party mods stay on the console (or local untracked folders).
+5. **AppleDouble sidecars** (`._*`) from some MTP clients can break zip/ROM/`.sav` scans — the launcher skips hidden `.*` names (including `._*.sav`); still prefer clean copies.
+
+## How we tested
+
+| Layer | What | Where |
+| ----- | ---- | ----- |
+| Unit / headless | Platform NX flags, RomImporter inbox, dual-path input, mod zip inbox, save `.sav` inbox, display chords, payload/self-tests | `tests/*`, `scripts/test.sh` |
+| Switch CI / packaging | Path-gated offline selftest (`selftest_build_switch.sh`, `verify_payload.sh --self-test`, `switch_ci_workflows_test.lua`); canonical fused PR artifact | `.github/workflows/ci.yml`, [switch-build.md](switch-build.md) § CI and release |
+| Probe on hardware | `getOS()==NX`, 1280×720, save path, Joy-Con events | `tools/switch-probe` → OLED |
+| Integration on hardware | MTP inbox ROM import, Play Red/Blue, naming A/B, quit/reopen save, suspend×10, reboot, fused NRO alone + NRO-only update | `docs/switch-hardware-evidence.md` |
+| Community hardware | Switch V1 / Erista boot with prebuilt NRO | [booshankles](https://github.com/booshankles) — see evidence log |
+| Known gaps | Docked soak, ≥30 min long-play, Lite, automated/`nxlink` deploy | Matrix deferred / absent rows |
+
+Operator evidence must stay in `docs/switch-hardware-evidence.md`. **Do not invent passes** for hardware not run.

+## love-nx 11.5-nx1 (pinned)
+
+**Tag:** [11.5-nx1](https://github.com/retronx-team/love-nx/releases/tag/11.5-nx1)
+
+**Local layout (not committed):**
+
+```text
+.bazinga/love-nx/11.5-nx1/
+├── love.nro    # homebrew launcher binary (loose mode: copied to gen1recomp.nro)
+└── love.elf    # required for fused NRO builds (devkitPro nacptool/elf2nro)
+```
+
+**Manifest:** `scripts/switch/love-nx-11.5-nx1.sha256` lists expected artifact names and SHA-256 checksums. Checksums are filled when binaries are fetched (`TBD_*` placeholders until then).
+
+### Fetch instructions
+
+Preferred (automated checksum verify):
+
+```bash
+scripts/build_switch.sh --fetch
+```
+
+That downloads pinned `love.nro` + `love.elf` into `.bazinga/love-nx/11.5-nx1/`
+and checks them against `scripts/switch/love-nx-11.5-nx1.sha256`. See
+[switch-build.md](switch-build.md) for the full mode glossary.
+
+Manual fallback:
+
+1. Open the [11.5-nx1 release](https://github.com/retronx-team/love-nx/releases/tag/11.5-nx1) and download `love.nro` and `love.elf`.
+2. Create the directory: `mkdir -p .bazinga/love-nx/11.5-nx1`
+3. Move both files into that directory.
+4. Confirm checksums match the manifest:
+
+   ```bash
+   shasum -a 256 .bazinga/love-nx/11.5-nx1/love.nro \
+     .bazinga/love-nx/11.5-nx1/love.elf
+   ```
+
+**Never commit** love-nx binaries, ROM dumps, or generated cache into git. The repo `.gitignore` excludes `.bazinga/` (vendor cache) and `/dist/` (build output).
+
+## Loose-mode dist layout
+
+Development builds place `gen1recomp.nro` and `game.love` side by side:
+
+```text
+dist/switch/loose/
+├── gen1recomp.nro
+└── game.love
+```
+
+Assemble with:
+
+```bash
+scripts/build_switch.sh --loose
+```
+
+(See `scripts/switch/assemble_loose.sh` for the underlying copy + checksum step.)
+
+## Transfer & deploy (current contributor loop)
+
+Detail for **macOS / Linux / Windows** and **MTP / SD / FTP** lives in
+[switch-transfer.md](switch-transfer.md). Summary:
+
+| Layer | Intent |
+| ----- | ------ |
+| **Runtime / players** | Extract the release zip at microSD root (`switch/gen1recomp/`) and land ROMs/mods under the save-dir inboxes. The game does not hard-depend on OpenMTP or macOS. |
+| **Contributor loop** | Manual copy via MTP (DBI responder), direct SD (Hekate UMS / reader), or FTP. Fully manual — no CI deploy, no `nxlink` yet. |
+
+The Mac + OpenMTP steps that remain below are the **OLED evidence reproduction** path; prefer the transfer runbook for day-to-day contrib on other hosts.
+
+**Still avoided for routine evidence** (keeps SD handling honest):
+
+- Treating `nxlink` / netloader as the release deploy story (deferred)
+- DBI `MicroSD install` / `NAND install` / NSP-style virtual folders for the `.love`/`.nro` pair
+
+If MTP fails: check cable, USB port, DBI state, and that only one MTP client holds the device — then retry or switch to SD/FTP. Do not silently rewrite evidence using an untested path and claim parity with recorded SHA-256 round-trips.
+
+### Manual deploy checklist (today)
+
+1. Build on the contributor host (`scripts/build_switch.sh --loose` or fused).
+2. Close Gen1Recomp on the Switch; open DBI → `Run MTP responder`.
+3. Copy artifacts with your MTP client into `1: SD Card/switch/gen1recomp/` (and ROMs/mods into the save-dir inboxes when needed).
+4. Wait for the transfer queue; refresh; optionally round-trip SHA-256 on first artifacts of a type.
+5. Exit MTP; launch via **title override** (hold **R** on a title → hbmenu, not Applet Mode).
+
+## OpenMTP + DBI transfer (loose build, Mac evidence example)
+
+Full multi-OS / multi-method steps: [switch-transfer.md](switch-transfer.md).
+The numbered Mac loop below reproduces the OLED evidence path.
+
+### On the Switch
+
+1. Close Gen1Recomp if it is running.
+2. Open **DBI** from hbmenu.
+3. Select **`Run MTP responder`** (DBI documents `X` on the main screen).
+4. Keep DBI on that screen for the entire transfer.
+5. Connect the Switch to the Mac with a USB-C data cable.
+
+### On the Mac
+
+1. Close any other MTP clients.
+2. Open **OpenMTP** and select the DBI device.
+3. In the remote pane, open **`1: SD Card`**.
+4. Navigate to **`switch/`** and create **`gen1recomp/`** if needed.
+5. Enter **`1: SD Card/switch/gen1recomp/`**.
+6. Drag from the local pane:
+
+   ```text
+   dist/switch/loose/gen1recomp.nro
+   dist/switch/loose/game.love
+   ```
+
+7. Wait for the OpenMTP queue to finish completely.
+8. Refresh the remote listing and confirm file sizes match the local files.
+9. On the Switch, exit MTP responder normally in DBI before launching the app.
+
+Expected layout on SD:
+
+```text
+1: SD Card/
+└── switch/
+    └── gen1recomp/
+        ├── gen1recomp.nro
+        └── game.love
+```
+
+## Round-trip SHA-256 verification
+
+For the **first deploy** of each artifact type (loose pair, later fused NRO), verify MTP integrity:
+
+1. **Before send** — record local hashes:
+
+   ```bash
+   shasum -a 256 dist/switch/loose/gen1recomp.nro \
+     dist/switch/loose/game.love
+   ```
+
+2. **After send** — in OpenMTP, copy the same files from `1: SD Card/switch/gen1recomp/` back to an empty local folder, e.g. `dist/switch/mtp-roundtrip/`.
+
+3. **Compare** round-trip hashes:
+
+   ```bash
+   shasum -a 256 dist/switch/mtp-roundtrip/gen1recomp.nro \
+     dist/switch/mtp-roundtrip/game.love
+   ```
+
+4. Local pre-send and round-trip hashes **must match**. Record results in the test report template below.
+
+Repeat whenever a cable glitch or interrupted transfer is suspected.
+
+## Title override launch (full memory)
+
+Applet Mode is **not** the primary validation path. Use **title override** so hbmenu runs with full memory:
+
+1. Confirm the OpenMTP transfer queue finished.
+2. Exit MTP responder in DBI; disconnect USB if desired.
+3. Hold **`R`** while launching any legitimately installed title.
+4. Keep holding until **hbmenu** appears.
+5. Confirm hbmenu does **not** show **Applet Mode**.
+6. Launch **`gen1recomp`** (or the probe NRO during Phase 0).
+
+Album / applet launches are only useful to document applet-specific limitations; P0/P1 gates use title override.
+
+## Phase 0 hardware checklist
+

+## Fast dev loop (loose mode)
+
+While iterating on Lua/assets:
+
+1. Edit on Mac; run `scripts/test.sh --quick`.
+2. Rebuild `.bazinga/work/game.love` (`scripts/build.sh mac --no-notarize` or project pack step).
+3. Close Gen1Recomp on Switch.
+4. DBI → `Run MTP responder`.
+5. OpenMTP → `1: SD Card/switch/gen1recomp/`.
+6. Replace **only** `game.love`; wait for queue + refresh listing.
+7. Exit MTP responder; launch via title override.
+8. Keep `gen1recomp.nro` unchanged until the love-nx pin changes.
+

+
+## Controller input mapping (NX)
+
+Measured on Switch OLED (`feat/switch-nx`, love-nx `11.5-nx1`, 1280×720). Both `joystickpressed` and `gamepadpressed` fire for Joy-Con; prefer the gamepad path when `joystick:isGamepad()` is true.
+
+| Path | Control | Mapping |
+| ---- | ------- | ------- |
+| `gamepadpressed` | D-pad / left stick | move |
+| `gamepadpressed` | SDL `a` / `b` on **NX** | swapped via `NX_GAMEPAD_BINDINGS`: physical **A** (east) = GB A confirm, physical **B** (south) = GB B cancel |
+| `gamepadpressed` | SDL `a` / `b` on desktop | identity (SDL south = GB A) |
+| `gamepadpressed` | `start` / `back` | Start / Select (+ / −) |
+| `gamepadpressed` | Right / left shoulder (no Select) | Cycle game speed up / down (same as PC hotkey `1` / speed-down path) |
+| `joystickpressed` (raw) | only if **not** `isGamepad()` | face/menu fallback |
+| `joystickpressed` (raw) | `#1` / `#2` on NX | Nintendo B / A → GB B / A |
+| `joystickpressed` (raw) | `#9` / `#10` | Select / Start (− / +) |
+
+**Nintendo UX on Switch:** physical A confirms, physical B cancels (explicit NX remap of SDL face labels).
+
+**Launcher extras** (`RomImporter`): physical **A** clicks at the virtual cursor; **L** / **R** switch tabs; **Start** / **Select** start Play when a ROM is ready (else open Choose ROM). D-pad / left stick move the virtual cursor.
+
+**Dual-path rule:** love-nx emits both `gamepadpressed` and `joystickpressed` for Joy-Con. When `joystick:isGamepad()` is true, Input and RomImporter **ignore raw** face/menu so NamingScreen does not see A+B in one frame. `NamingScreen` also prefers A over B if both edges still fire.
+
+Implementation: `src/core/GamepadMap.lua` (`NX_RAW_*`, `ignoreRawForJoystick`, `displayChordDigit`), `src/core/Game.lua` (shoulder speed), `src/import/RomImporter.lua` (launcher tabs). Launcher and gameplay share the same converter.
+
+## ROM inbox (NX)
+
+Legal dumps land in a shared MTP inbox; **Scan again** is tab-scoped:
+
+| Item | Value |
+| ---- | ----- |
+| Save-relative path | `imports/` (also accepts loose `.gb`/`.gbc` at the save-dir root) |
+| MTP destination | `1: SD Card/<save identity>/imports/` (see launcher notice for the live `getSaveDirectory()` path) |
+| Candidates | `*.gb` / `*.gbc` (hidden `.*` AppleDouble names skipped) |
+| Rescan | Game tab → **Scan again** — imports only the dump whose SHA-1 matches that tab (`GameVersion.forSha1`). Other known dumps stay for their own tabs |
+| Already ready | Same SHA already imported → “No new ROM found.” |
+
+Players may drop Red, Blue, and Yellow into the same folder. Opening Yellow and pressing **Scan again** must not start a Red import.
+
+## Mod zip inbox (NX)
+
+Community mods install from a **separate** MTP inbox (not mixed into the ROM `imports/` scan):
+
+| Item | Value |
+| ---- | ----- |
+| Save-relative path | `imports/mods/` |
+| MTP destination | `1: SD Card/<save identity>/imports/mods/` (see launcher notice for the live `getSaveDirectory()` path) |
+| Candidates | `*.zip` only |
+| Rescan | MODS tab → **Scan again** (installs each zip via `LauncherMods.installZip`; source zips are retained on success and failure) |
+| FIND MODS | Remains network-gated / hidden on NX (`networkValidated == false`) |
+
+Do **not** commit third-party mod zip bytes into git. Drop the zip over MTP, rescan, enable in MODS, then Play.
+
+**MTP tip (esp. macOS clients):** OpenMTP/Finder often creates AppleDouble sidecars named `._Something.zip` / `._cart.gb` / `._foo.sav`. Those are not real archives, ROMs, or saves — the launcher ignores hidden `.*` names under `imports/`, `imports/mods/`, and `imports/saves/<game>/`. If install still fails with “could not be opened” / “not a zip file”, delete any `._*` under the inbox and confirm the real zip starts with the `PK` magic (re-copy the release asset if unsure). This is a host-side annoyance of the current manual MTP loop, not something players should need forever.
+
+Drop any community release `.zip` into `imports/mods/`, rescan, enable.
+Player-facing install steps: [switch-install.md](switch-install.md#community-mods).
+Mods own their OPTIONS / rebinds — do not duplicate third-party control tables here.
+
+## Save `.sav` inbox (NX)
+
+Raw Gen1 battery images use a **separate** MTP inbox (not mixed into ROM `imports/` or mod `imports/mods/`):
+
+| Item | Value |
+| ---- | ----- |
+| Save-relative path | `imports/saves/red/`, `imports/saves/blue/`, `imports/saves/yellow/` |
+| MTP destination | `1: SD Card/<save identity>/imports/saves/<game>/` (see launcher notice for the live `getSaveDirectory()` path) |
+| Candidates | non-hidden `*.sav` only in **that game’s** folder |
+| Rescan | SAVE FILES → **Import save** on the matching game tab (scans only that folder) |
+| After success | Retire to `*.sav.imported` + append content hash to `imports/saves/<game>/.imported-sha1` |
+| Exports | **Export save** writes under `exports/<game>/gen1recomp-<game>-<slot>.sav`; NX shows an MTP path notice (no `openURL`) |
+
+Do **not** commit `.sav` bytes into git. Drop the file into the matching game folder over MTP, press **Import save** on that tab, then play. Pull exports from `exports/<game>/`.
+
+**MTP tip:** the same AppleDouble `._*.sav` rule applies — see the mod inbox tip above.
+
+## Joy-Con display chords (Select + face)
+
+PC digit hotkeys for COLORS / TILT / GBC FX / pipelines have Joy-Con equivalents. Hold **Select** (`back` / −) and press a face/shoulder button; the engine runs the same path as `Game:keypressed` for that digit (including `writeOptions` / Pipelines parity).
+
+| Chord (Nintendo UX) | Engine key | Stock engine effect |
+| ------------------- | ---------- | ------------------- |
+| Select + **A** | `2` | COLORS cycle |
+| Select + **B** | `3` | TILT / perspective |
+| Select + **Y** | `5` | GBC FX |
+| Select + **X** | `6` | Mod pipeline hotkey (if registered) |
+| Select + **L** (left shoulder) | `7` | Mod pipeline hotkey (if registered) |
+
+Keys `2` / `3` / `4` / `5` are claimed by the engine before mod pipeline hotkeys run, so a community mod cannot rebind those digits through `Pipelines.hotkey`. Mods that need their own controls should use OPTIONS rows or unclaimed hotkeys.
+
+Without Select held, face buttons keep normal GB A/B gameplay mapping (no accidental color/tilt cycles). The **Options** menu remains available for the same settings — chords are optional shortcuts, not the only path.
+
+On NX, A/B chords resolve through the Nintendo UX face remap so physical **A** → key `2` and physical **B** → key `3` match this table.
+
+**OPTIONS → PERFORMANCE** clamps the port’s own extras (TILT / GBC FX / survey ZOOM) and can cap FPS — useful on weaker handheld budgets. Details: [new-features.md — Performance tier](new-features.md#performance-tier-low-end-devices).
+
+Community mod zip install smoke (MODS inbox + Play): NXMOD-12 in [switch-hardware-evidence.md](switch-hardware-evidence.md).
+
+**Opt-in diagnostics:** create an empty `switch-debug.txt` in the save directory; events flush to `switch.log` at ≤1 Hz with build identity (no ROM/save bytes).
+
+**NX asset probe (always on Play):** every Switch Play writes `nx-asset-probe.log` in the save directory (`pokemon-love2d/`). It lists whether `assets/generated/…` vs `yellow|blue/assets/generated/…` exist, what `Assets.resolve` returns, and whether `newImage` / `newImageData` open — for Yellow/Blue blank-sprite triage. No ROM bytes.
+
+**Blue/Yellow cache overlay (NX):** fused love-nx cannot reliably mount `yellow|blue/assets/generated` onto the un-prefixed path, so `src/core/NxAssetOverlay.lua` wraps EVERY read-side love API that accepts a filesystem path (`filesystem.read/load/lines/newFileData/getInfo`, `graphics.newImage/newFont`, `image.newImageData`, `audio.newSource`, `sound.newSoundData`, `font.newFontData`) once at boot — only when `Platform.isNX()`. Covering the whole read surface (not just the loaders the boot needs today) keeps future states and mods inside the fallback automatically; write-side functions stay stock. Core code must NOT call love loaders on literal `assets/generated` paths (enforced by `tests/engine/nx_generated_guard_test.lua`); the chip-audio worker is a separate Lua state and gets the prefix explicitly via `audio.programPrefix` from `ChipAudio.slimAudio`.
+
+**Hardware re-test:** T16 **pass** @ `2699c9a` (naming A=confirm / B=cancel). T19 **pass** (quit/reopen, suspend×10, reboot) — operator 2026-08-01.
+
+**Suspend/resume audio:** after resume, chip music is stopped to avoid duplicate streams; confirm on hardware during P0-09/10 (T19).
+
+## Lua error log (save directory)
+
+On any uncaught Lua error, Gen1Recomp appends a redacted trace to `lua-error.log` in the LÖVE save directory (`love.filesystem.getSaveDirectory()`). The on-screen error overlay includes a hint pointing at that file. Logs rotate to `lua-error.log.1` when the active file exceeds 32 KiB. ROM/save bytes and non-printable data are stripped — never commit or share logs that might contain private paths without reviewing them first.
+
+## Native crash triage (love-nx / Atmosphère)
+
+love-nx native faults land under the console’s `crash_reports/` folder on SD (reachable via the same manual MTP workflow used for game deploys).
+
+1. **Collect** — DBI → `Run MTP responder`; copy `sdmc:/crash_reports/*.bin` (or the dated subfolder) to the contributor host. Prefer keeping the microSD in-console for routine pulls.
+2. **Redact** — delete any attached screenshots or notes that mention ROM filenames, save paths, or private hashes before sharing logs publicly.
+3. **Symbolize** — use the **pinned** `love.elf` from `.bazinga/love-nx/11.5-nx1/` that matches `build-info.json` / `scripts/switch/love-nx-11.5-nx1.sha256`. Never use a “latest” download.
+
+   ```bash
+   # Example: aarch64-none-elf-addr2line from devkitPro
+   aarch64-none-elf-addr2line -e .bazinga/love-nx/11.5-nx1/love.elf -f -C 0xADDRESS_FROM_CRASH_REPORT
+   ```
+
+4. **Correlate** — compare `gitCommit` / `loveNxTag` from embedded `build-info.json` with the operator’s hardware notes.
+
+If `addr2line` cannot resolve an address, archive the crash `.bin` with the exact `love.elf` SHA-256 used for the build — addresses are only meaningful against that ELF.

+## Review guidance
+
+Maintainers may review as one PR or split later. Suggested slices (optional):
+
+Each slice should declare: **no ROM/save bytes committed**, **love-nx pin with manifest checksums**, **hardware-tested rows listed with linked evidence**, **Applet Mode unsupported**, **network/updater disabled on NX**, **deploy still manual** (MTP / SD / FTP; no nxlink yet), **OpenMTP is one example not the sole contract**.
+
+### Slice 1 — Platform + import (`platform/import`)

+- `src/core/Platform.lua`, `conf.lua` NX branch
+- `src/import/RomImporter.lua` (NX flags, inbox, scan, shell/updater gates)
+- Tests: `tests/engine/platform_nx_*`, `tests/engine/rom_importer_nx_*` (ROM-free T2)
+- Docs: inbox/MTP import sections only
+
+### Slice 2 — Input + lifecycle (`input/lifecycle`)
+
+- `src/core/GamepadMap.lua`, `Input.lua`, `main.lua` focus/joystick hooks
+- `src/debug/SwitchDiagnostics.lua` (opt-in probe + error log)
+- Tests: input/diagnostics suites
+- Docs: controller mapping, suspend/audio notes
+
+### Slice 3 — Build + docs (`build/docs`)
+
+- `scripts/pack_love.sh`, `scripts/build_switch.sh`, `scripts/switch/*`
+- `assets/switch/icon.jpg`, `docs/switch-development.md`, hardware evidence templates
+- Gates: `pack_love.sh --dry-run`, `verify_payload.sh --self-test`, fused build script (devkitPro host)
+
+**Pre-merge checklist:**
+
+- [ ] Manifest `scripts/switch/love-nx-11.5-nx1.sha256` filled; binaries not in git
+- [ ] `verify_payload.sh` rejects generated cache / ROM / `.sav` / `.bak`
+- [ ] P0 matrix rows marked pass only with linked hardware evidence
+- [x] Fused NRO P0-12/14/15 pass with T24 evidence (`docs/switch-hardware-evidence.md`)

+# Install Gen1Recomp on Nintendo Switch
+
+Every GitHub Release that includes Switch support ships an SD-ready zip:
+`gen1recomp-*-switch.zip`. Extract it at the root of your microSD (install
+**or** update — same steps), launch with **title override**, then import your
+own legal `.gb` ROM.
+
+> You need a console that can run Switch homebrew (custom firmware / hbmenu).
+> This project does not help you set that up. Tracks issue
+> [#531](https://github.com/bryanthaboi/gen1recomp/issues/531).
+> Hardware: **OLED** validated by the porter; **V1 / Erista** boot confirmed
+> by the community. Lite and other setups welcome more reports.
+> See [switch-development.md](switch-development.md) for limitations.
+
+Prefer building from source? See [switch-build.md](switch-build.md).
+
+Port by [andrewqsantos](https://github.com/andrewqsantos). Community testing
+help from [booshankles](https://github.com/booshankles).
+
+## 1. Download the zip
+
+1. Open
+   [Releases](https://github.com/bryanthaboi/gen1recomp/releases).
+2. Download `gen1recomp-*-switch.zip` for the version you want.
+   (Optional: verify against `sha256sums.txt` in the same release.)
+
+## 2. Extract onto the microSD
+
+Extract the zip at the **root** of the microSD so you get:
+
+```text
+sdmc:/switch/gen1recomp/gen1recomp.nro
+sdmc:/switch/gen1recomp/pokemon-love2d/imports/
+sdmc:/switch/gen1recomp/pokemon-love2d/imports/mods/
+sdmc:/switch/gen1recomp/pokemon-love2d/imports/saves/...
+```
+
+Merge folders if your OS asks. Any method works: **MTP** (DBI → Run MTP
+responder + a client), **direct SD** (Hekate UMS or a card reader), or **FTP**.
+Exit MTP / unmount / stop FTP cleanly before launching. Step-by-step for
+macOS, Linux, and Windows: [switch-transfer.md](switch-transfer.md).
+
+### Updating
+
+Use the **same** extract/merge. It replaces `gen1recomp.nro` (and the small
+help `README.txt` / `INSTALL.txt` files). Saves, imported ROMs, mods, and
+options live under `pokemon-love2d/` — **do not delete that folder** when
+updating, or you will lose progress.
+
+## 3. Launch with title override
+
+**Applet Mode is not supported** for this game (not enough memory).
+
+1. On the Switch HOME menu, highlight any installed title.
+2. Hold **R** and launch that title — this opens hbmenu with full memory
+   (title override).
+3. From hbmenu, open `gen1recomp`.
+
+Do **not** launch from the Album applet path for normal play.
+
+## 4. Import your ROM
+
+This project ships **no** game data. On first launch:
+
+1. Put your own legally obtained Pokémon Red, Blue (`.gb`), or Yellow
+   (`.gbc`) dump into `switch/gen1recomp/pokemon-love2d/imports/` (the
+   launcher also shows the live save-dir path). All three can sit in the
+   same folder.
+2. Use **Scan again** on that game’s tab (Red / Blue / Yellow). Rescan
+   matches by ROM SHA-1 for the open tab only — a Red dump never imports
+   from the Yellow tab (and vice versa).
+
+## 5. Import / Export a raw `.sav`
+
+Continue a cart or PC battery save (or pull a slot off-console) via MTP /
+SD / FTP — same transfer methods as ROMs. Paths are **per game**:
+
+| Game | Import inbox | Export folder |
+| ---- | ------------ | ------------- |
+| Red | `imports/saves/red/` | `exports/red/` |
+| Blue | `imports/saves/blue/` | `exports/blue/` |
+| Yellow | `imports/saves/yellow/` | `exports/yellow/` |
+
+(Under the save dir `pokemon-love2d/` — the zip already creates these folders.)
+
+1. Copy a Gen1 `.sav` (32 KB) into that game’s inbox under the save dir
+   ([switch-transfer.md](switch-transfer.md)).
+2. With the game’s ROM already imported, open **that game’s tab** →
+   **SAVE FILES** → **Import save**. Only that folder is scanned.
+3. A successful import retires the file to `*.sav.imported` and records its
+   content hash so pressing **Import save** again does not clone slots.
+   Failed imports leave the original `.sav` in place.
+4. To pull a slot off the console, use **Export save**, then copy the file
+   from that game’s **`exports/<game>/`** folder via MTP / SD / FTP.
+
+Do not put `.sav` files into git. Prefer clean copies — some MTP clients
+create `._*.sav` AppleDouble sidecars that are not real saves.
+
+## Controls
+
+### Gameplay
+
+| Control | Action |
+| ------- | ------ |
+| D-pad / left stick | Move |
+| **A** | Confirm |
+| **B** | Cancel |
+| **+** (Start) | Start |
+| **−** (Select) | Select |
+| **R** (no Select held) | Cycle game speed up |
+| **L** (no Select held) | Cycle game speed down |
+
+### Launcher
+
+| Control | Action |
+| ------- | ------ |
+| D-pad / left stick | Move virtual cursor |
+| **A** | Click at cursor |
+| **L** / **R** | Previous / next tab |
+| **Start** / **Select** | Play if a ROM is ready; otherwise Choose ROM |
+
+### System
+
+| Control | Action |
+| ------- | ------ |
+| Hold **R** on HOME, then open from hbmenu | Title override (full memory) |
+
+## Community mods
+
+Mods install from a zip inbox (same transfer methods as ROMs):
+
+1. Copy a release `.zip` into the save-dir **`imports/mods/`** path the
+   launcher shows (MTP / SD / FTP — [switch-transfer.md](switch-transfer.md)).
+2. In the launcher, open **MODS** → **Scan again** → enable the mod →
+   **Play**.
+
+Remote **FIND MODS** / GitHub download stays **off** on Switch. Do not put
+mod zips into git. Community mods ship their own OPTIONS / rebinds — this port
+does not document third-party control tables.
+
+### Joy-Con shortcuts (Select + face)
+
+Hold **Select** (−) and press a face/shoulder button. Without Select, A/B stay
+normal gameplay confirm/cancel. These chords are the stock engine display
+hotkeys (`2`/`3`/`5` are claimed before any mod pipeline hotkey runs).
+
+| Chord | Same as PC key | Stock engine effect |
+| ----- | -------------- | ------------------- |
+| Select + **A** | `2` | COLORS |
+| Select + **B** | `3` | TILT |
+| Select + **Y** | `5` | GBC FX |
+| Select + **X** | `6` | Mod pipeline hotkey (if a mod registers `6`) |
+| Select + **L** | `7` | Mod pipeline hotkey (if a mod registers `7`) |
+
+If the handheld stutters with extras on, try **OPTIONS → PERFORMANCE** →
+`LOW` or `BALANCED`. Full chord notes for contributors:

+# Switch file transfer (MTP / SD / FTP)
+
+Canonical ways to put Gen1Recomp artifacts and inbox files onto a Nintendo
+Switch. **Any method is valid** if the bytes land in the destinations below.
+
+This is the home runbook for contributors on **macOS, Linux, and Windows**.
+Player install (what to download, title override) stays in
+[switch-install.md](switch-install.md). Packaging stays in
+[switch-build.md](switch-build.md). Hardware evidence lives in
+[switch-hardware-evidence.md](switch-hardware-evidence.md).
+
+> **Not supported yet:** `nxlink` / hbmenu netloader automation. Useful later
+> for a fast contrib rebuild loop; deferred on purpose (AD-009). Do not treat
+> netloader as the release or ROM/mod install path.
+
+---
+
+## Destinations (shared by every method)
+
+| What | Where on the console |
+| ---- | -------------------- |
+| SD-ready release zip | Extract at microSD **root** → `sdmc:/switch/gen1recomp/gen1recomp.nro` plus `pokemon-love2d/` inbox folders. Install and update use the same merge; do **not** delete `pokemon-love2d/` |
+| Loose iteration pair | `sdmc:/switch/gen1recomp/gen1recomp.nro` **and** `game.love` beside it |
+| ROM inbox | LÖVE save dir → `imports/` (launcher shows the live `getSaveDirectory()` path; under MTP often `1: SD Card/<save identity>/imports/`) |
+| Mod zip inbox | Same save dir → `imports/mods/` then MODS → **Scan again** |
+| Save `.sav` inbox | Same save dir → `imports/saves/red\|blue\|yellow/` then that game’s SAVE FILES → **Import save** |
+| Save exports | Same save dir → `exports/red\|blue\|yellow/` (pull after **Export save**; MTP / SD / FTP) |
+| Opt-in diagnostics | Empty `switch-debug.txt` in the save dir → `switch.log` |
+| Lua error log | `lua-error.log` in the save dir |
+
+Saves persist across zip re-extract / NRO replacements as long as
+`pokemon-love2d/` is left in place. Never commit ROM dumps, `.sav`
+files, or third-party mod zips to git.
+
+---
+
+## Canonical methods
+
+### 1. MTP (DBI responder + host client)
+
+On the Switch: close Gen1Recomp → open **DBI** → **Run MTP responder** (often
+**X** on the main screen) → keep that screen up → USB-C data cable to the host.
+
+On the host: open **one** MTP client, navigate to **`1: SD Card`**, then the
+paths above. Wait for the transfer queue; refresh; exit MTP on the Switch
+before launching.
+
+#### macOS (example: OpenMTP)
+
+[OpenMTP](https://github.com/ganeshrvel/openmtp) is the loop used for OLED
+hardware evidence — **one contributor example**, not a Mac-only product rule.
+
+1. Quit other MTP clients.
+2. Open OpenMTP → select the DBI device → **`1: SD Card`**.
+3. Create `switch/gen1recomp/` if needed; extract the release zip at SD root
+   (or copy NRO / `game.love` for loose).
+4. For ROMs/mods/saves, open the save-dir `imports/`, `imports/mods/`,
+   `imports/saves/<red|blue|yellow>/`, or `exports/<red|blue|yellow>/` path the
+   launcher prints.
+5. Wait for the queue; refresh; exit MTP responder; title-override launch.
+
+macOS clients often create AppleDouble sidecars (`._Something.zip`,
+`._cart.gb`, `._foo.sav`). Those are not real archives or saves — the
+launcher skips hidden `.*` names. Delete `._*` junk if a zip/ROM/`.sav`
+fails to open.
+
+#### Linux
+
+1. Install desktop MTP support if needed (e.g. `gvfs-mtp` on GNOME/GTK
+   desktops, or your distro’s KDE MTP stack).
+2. With DBI MTP active, open **Files** / **Dolphin** / **Thunar** and select
+   the Switch / DBI device → **`1: SD Card`**.
+3. Extract the release zip at SD root (merge), or copy into `switch/gen1recomp/`
+   and the save-dir inboxes as above.
+4. Use **only one** MTP accessor at a time. If `mtp-tools` / `mtpfs` reports
+   “device is busy”, close the file manager’s MTP mount (or the CLI mount)
+   and retry with a single client.
+5. Eject/unmount cleanly; exit MTP on the Switch; title-override launch.
+
+If MTP is unavailable or flaky on Linux, use **direct SD** (Hekate UMS or a
+card reader) or **FTP** instead — same destinations in the table above.
+
+#### Windows
+
+1. With DBI MTP active, open **This PC** / **File Explorer** and look under
+   **Portable Devices** for the Switch / DBI MTP volume → **`1: SD Card`**.
+2. Copy / extract into `switch\gen1recomp\` and the save-dir inboxes.
+3. Optional: [OpenMTP](https://github.com/ganeshrvel/openmtp) on Windows if
+   Explorer is flaky.
+4. If Windows does not show an MTP device: Device Manager → find DBI / Switch
+   → Update driver → **MTP USB Device** (or Standard MTP Device). Prefer a
+   data-capable USB-C cable and a direct port.
+5. Safely disconnect; exit MTP on the Switch; title-override launch.
+
+If MTP is unavailable or flaky on Windows, use **direct SD** (Hekate UMS or a
+card reader) or **FTP** instead — same destinations in the table above.
+
+### 2. Direct SD (Hekate UMS or card reader)
+
+Same destinations; no MTP client required.
+
+- **Hekate UMS** (preferred when available): expose the microSD to the host
+  while the card stays in the console; mount the volume; copy files; **cleanly
+  unmount** before leaving UMS.
+- **Physical reader**: power off / remove the microSD, copy on the host,
+  **eject safely**, reinsert, boot CFW, title-override launch.
+
+Do not yank the card or unplug UMS mid-write.
+
+### 3. FTP (any SD-exposing Switch FTP)
+
+Any homebrew FTP server that can write the microSD is fine — for example
+**DBI’s own FTP**, **sys-ftpd-light**, or **Sphaira** (names are illustrations
+only; pick what your CFW setup already uses).
+
+1. Start the FTP server on the Switch; note IP/port/credentials from that app.
+2. From the host, connect with any FTP client and upload to the same
+   `switch/gen1recomp/`, `imports/`, `imports/mods/`, `imports/saves/<game>/`,
+   and `exports/<game>/` paths.
+3. Stop the FTP server cleanly before launching Gen1Recomp.
+
+If credentials or chroots differ by app, trust the **destination paths**, not
+a single vendor tutorial.
+
+---
+
+## After every transfer
+
+1. Exit MTP / unmount SD / stop FTP cleanly.
+2. Launch via **title override** (hold **R** on a title → hbmenu). **Applet
+   Mode is not supported** (not enough memory).
+3. For ROMs: open the matching game tab → **Scan again** if the file was
+   added after boot (SHA-1 must match that tab; other dumps in `imports/`
+   stay for their own tabs). For mods: MODS → **Scan again** → enable →
+   Play. For saves: SAVE FILES → **Import save** (rescans
+   `imports/saves/<game>/`). Pull exported `.sav` files from
+   `exports/<game>/`. Joy-Con display chords (stock engine):
+   [switch-install.md](switch-install.md#joy-con-shortcuts-select--face).
+
+### Optional NRO integrity check
+
+For the first deploy of a given artifact (or after a flaky cable):
+
+```bash
+shasum -a 256 path/to/gen1recomp.nro   # or sha256sum
+```
+
+Copy the file back from the SD and compare hashes. Round-trip must match.
+
+---
+
+## Failure modes (quick)
+
+| Symptom | What to try |
+| ------- | ----------- |
+| Device busy / no MTP volume | One client only; different cable/port; Windows MTP USB Device driver; alternate method (SD or FTP) |
+| Zip/ROM/`.sav` “could not be opened” | Delete `._*` sidecars (including `._*.sav`); confirm real zip starts with `PK` |
+| Half-copied NRO / crash on boot | Re-copy; verify SHA-256; exit transfer mode before launch |
+| App opens in Applet Mode | Use title override (hold **R**), not Album |

+# Timing parity with the Game Boy
+
+The port's clock is faithful: `src/core/FixedStep.lua` advances game logic in
+whole 1/60 s steps off wall-clock `dt`, the default speed multiplier is 1x
+(`src/core/GameSpeed.lua:22`), and audio runs on its own real-time accumulator
+so fast-forward cannot pitch it. Almost nothing in `src/` is seconds-based.
+
+What diverges is the **frame budget of composed sequences**. The original
+spends a large fraction of its running time inside `DelayFrames` calls that
+produce no visible change - the pause after a page break, the beat before a
+status move resolves, the drain of an HP bar one point at a time. Those are
+invisible in a screenshot and easy to drop when porting behavior rather than
+timing. Dropping them is why the port reads as faster and snappier than
+hardware even though every individual animation is correct.
+
+This document is the specification: what each sequence costs on hardware, and
+where that number comes from.
+
+## Method
+
+`tools/scan_pokered_delays.ps1` walks the disassembly and reports every
+frame-consuming wait with its enclosing routine label:
+
+| Kind | Meaning | Frames |
+| --- | --- | --- |
+| `DelayFrames` | `ld c, N` + `call DelayFrames` (`home/delay.asm:1`) | N |
+| `DelayFrame` | one vblank wait (`home/vblank.asm:92`) | 1 |
+| `Delay3` | `home/palettes.asm:14`, three frames for a full bg-map update | 3 |
+| `Fade` | the `GBFade*` helpers, expanded to their totals below | 24 or 32 |
+
+Current inventory against `pokered-master`: **450 sites** - 181 `DelayFrames`,
+164 `Delay3`, 65 `DelayFrame`, 31 `GBFade*`, and 9 `DelayFrames` calls whose
+count is computed at runtime.
+
+The four fades all live in `home/fade.asm` and are loops of
+`ld c, 8 / call DelayFrames`:
+
+| Routine | Iterations | Frames | Source |
+| --- | --- | --- | --- |
+| `GBFadeInFromBlack` | 4 | **32** | `home/fade.asm:21` |
+| `GBFadeOutToBlack` | 4 | **32** | `home/fade.asm:43` |
+| `GBFadeOutToWhite` | 3 | **24** | `home/fade.asm:26` |
+| `GBFadeInFromWhite` | 3 | **24** | `home/fade.asm:48` |
+
+## The metric
+
+For each catalog entry, `delta = |port - truth| / truth`; the entry passes at
+`delta <= 0.05`. The headline number is the **exposure-weighted** pass rate,
+weighting each sequence by how often it occurs in ordinary play - a 30-frame
+error on every page of dialogue matters more than a 30-frame error in the Hall
+of Fame. Weights are in the tier column: T1 sequences recur constantly, T2 are
+frequent, T3 are set pieces seen once or twice per playthrough.
+
+## Tier 1 - constant exposure
+
+These recur every few seconds of play and dominate perceived pacing. Both
+sides are verified.
+
+### Overworld and transitions
+
+| Sequence | Hardware | Source | Port | Port source | Delta |
+| --- | --- | --- | --- | --- | --- |
+| Overworld loop iteration | 2 frames (two `DelayFrame`) | `home/overworld.asm:41-44` | 1 step | `src/core/Game.lua:174` | see note |
+| Warp / door: fade out | **32** | `home/overworld.asm:703` -> `GBFadeOutToBlack` | 32 | `src/render/Transition.lua` | **fixed** |
+| Warp / door: fade in | **0** (map is drawn under blacked palettes, no fade) | `home/overworld.asm:690-703` | 0 | `src/render/Transition.lua` | **fixed** |
+| Return to overworld after a battle | **10** hold, then `GBFadeInFromWhite` **24** | `home/overworld.asm:351-352`, `:22`, `:749-753` | 10 + 24 | `Transition.battleReturn` | **fixed** |
+| Special warp entry (fly / teleport / dungeon) | `Delay3` + `GBFadeInFromWhite` = **27** | `engine/overworld/player_animations.asm:5-7` | - | - | unmeasured |
+| Dungeon-warp arrival hold | **50** | `engine/overworld/player_animations.asm:43` | - | - | unmeasured |
+| Player step (walk) | 16 | 8 loop iterations x 2 frames | 16 | `src/world/Player.lua:14` | **ok** |
+| Turn in place | 2 | one extra loop pass | 2 | `src/world/Player.lua:18` | **ok** |
+
+Note on the overworld loop: `OverworldLoop` calls `DelayFrame` and then falls
+through to `OverworldLoopLessDelay`, which calls it again - so a full pass
+costs 2 frames, and input is sampled every other frame. The port steps logic
+and samples input every frame. This does not change walking speed (the 2-frame
+loop moves 2 px, giving the same 16 frames per tile) but it does halve input
+latency versus hardware. Flagged rather than "wrong": matching it exactly would
+make the port feel less responsive than the original does on a modern display,
+and it is the one place where a deliberate divergence is defensible.
+
+### Text
+
+The typewriter cadence itself is already correct - 1/3/5 frames per character
+from `TextSpeedOptionData`, implemented at `src/render/TextBox.lua:267`. The
+gaps around it are missing.
+
+| Sequence | Hardware | Source | Port | Port source | Delta |
+| --- | --- | --- | --- | --- | --- |
+| `<CONT>` line scroll (after the A press) | `ProtectedDelay3` 3 + 2x `ScrollTextUpOneLine` 5 = **13** | `home/text.asm:262-277`, `:283-307` | 13 | `src/render/TextBox.lua` | **fixed** |
+| `<PARA>` paragraph break | `ProtectedDelay3` 3 + clear + **20** = **23** | `home/text.asm:230-243` | 23 | `src/render/TextBox.lua` | **fixed** |
+| Page break (`PageChar`) | 3 + **20** = **23** | `home/text.asm:245-260` | 23 | `src/render/TextBox.lua` | **fixed** |
+| `TextCommand_PAUSE` | **30** | `home/text.asm:500` | - | - | unmeasured |
+| `TextCommand_DOTS` | **10** per dot | `home/text.asm:576` | - | - | unmeasured |
+
+The three ProtectedDelay3 frames are a *pre*-input hold: the arrow is already
+up and the button is ignored, because `ManualTextScroll` only starts watching
+the joypad after the delay returns. Mashing A through a long conversation
+therefore cannot go faster than 3 frames per line on hardware, and now cannot
+here either. `PromptText` (`home/text.asm:209-217`) has the same shape, so a
+finished page holds three frames before it can be dismissed too.
+
+**Battle text is a second, separate engine.** `BattleState` types its own
+messages rather than going through `src/render/TextBox.lua`, so none of the
+fixes above reached it and it had drifted further than the overworld box:
+
+| Sequence | Hardware | Source | Was | Now |
+| --- | --- | --- | --- | --- |
+| Per character | 1 glyph per `wOptions & $f` frames (1/3/5, default **3**) | `home/print_text.asm:4-45` | 2 glyphs **per frame**, option ignored | 3 |
+| Per character, A or B held | **1** frame | `print_text.asm:27-36` | 2 glyphs per frame | 1 |
+| `<CONT>` pre-input hold | **3** | `home/text.asm:263-267` | 0 | 3 |
+| `<CONT>` scroll after the press | **10** | `home/text.asm:280-305` | 0 | 10 |
+| Finished page, pre-input hold | **3** | `home/text.asm:213-217` | 0 | 3 |
+
+At the default text speed the battle typewriter was running **six times**
+hardware speed, which is most of why battle text read as a blur, and it
+ignored the OPTION text-speed setting entirely.
+
+`ScrollTextUpOneLine` is `ld b, 5` of `DelayFrame` (`home/text.asm:301-305`)
+and its own comment notes it is "always called twice in a row", so a CONT
+scroll blocks for 10 frames. The port's `scrollPx` slide at
+`src/render/TextBox.lua:305-307` is a cosmetic 8 px at 2 px/frame running in
+`draw()`, not on the logic step, and it does not gate the typewriter.
+
+### Menus
+
+| Sequence | Hardware | Source | Port | Port source | Delta |
+| --- | --- | --- | --- | --- | --- |
+| Yes/no answer (either option) | **15** | `engine/menus/text_box.asm:322-323`, `:333-334` | 15 | `src/ui/ChoiceBox.lua` | **fixed** |
+| List menu open (bag, PC, party-as-list) | **10** | `home/list_menu.asm:55-56` | 0 | `src/ui/ListMenu.lua` | **-100%, open** |
+| List menu redraw per input | `Delay3` = **3** | `home/list_menu.asm:64` | 0 | - | **-100%, open** |
+| Field move from the party menu | `Delay3` = **3** | `engine/menus/start_sub_menus.asm:4,27,175-203` | 7 (white flash) | `src/render/Transition.lua:8` | see note |
+| Teleport from the party menu | **60** + `Delay3` | `engine/menus/start_sub_menus.asm:224-225` | - | - | unmeasured |
+
+The port's 7-frame `white_flash` models `GBPalWhiteOutWithDelay3` plus the
+screen-tile restore, which is a defensible reading of the same sequence; it is
+listed here to be reconciled against the exact path rather than treated as a
+bug.
+
+### Battle entry
+
+The wipe into a battle and the silhouette slide behind it. Numbers here come
+from **pokered-c** (`C:\Users\Anthony\pokered`), whose `battle_transition.c`
+derives each wipe from `battle_transitions.asm` and then corrects it against a
+live side-by-side with the ROM. Where that project's measured value and a
+naive reading of the asm disagree, the measured value wins - see the inward
+spiral below.
+
+| Sequence | Hardware | Was | Now |
+| --- | --- | --- | --- |
+| DoubleCircle wipe (wild, weak) | 10 x 3 = **30** | 40 | 30 |
+| Circle wipe (wild, strong) | 20 x 3 = **60** | 40 | 60 |
+| Spiral outward (trainer, strong) | 360 fills / 3 per frame = **120** | 40 | 120 |
+| Spiral inward (trainer, weak) | 7 tiles per `Delay3` = **~150** | 40 | 156 |
+| HStripes (dungeon wild, weak) | 20 x 3 = **60** | 24 | 60 |
+| VStripes (dungeon wild, strong) | 18 x 3 = **54** | 24 | 54 |
+| Shrink (dungeon trainer, weak) | 9 x 6 = **54** | 24 | 54 |
+| Split (dungeon trainer, strong) | 9 x 6 = **54** | 24 | 54 |
+| Flash before the circle wipes | 12 x 2 x 3 = **72** | 72 | 72 |
+| Black hold before the battle draws | not stated by pokered; ~30 floor, calibrated **60** | 30 | 60 |
+| Silhouette slide in | 144 px at 2 px/frame = **72** | 40 (160 px at 4 px/frame) | 72 |
+| Trainer intro, before balls + text | `WaitForSoundToFinish` + `DelayFrames 20` | 0 | sfx wait + 20 |
+
+The trainer intro's sound is `SFX_Silph_Scope`, extracted here as
+`Trainer_Appeared` (`tools/rom_manifest.json` `audio.sfxHeaders`, bank 8 /
+`$42bb`). It was being extracted and never played by anything. It now plays
+into a clear window: `PrintBeginningBattleText .trainerBattle` does
+`PlaySound` then `WaitForSoundToFinish`, which **blocks**, and only then
+`DelayFrames 20` before `DrawAllPokeballs` and the text. `BattleState`'s
+message queue grew a `waitSound` row for that, since `WaitForSoundToFinish`
+waits on the sound actually stopping rather than on a fixed frame count.
+
+**Scripted battles were skipping the transition entirely.** `BattleTransition`
+runs from `DoBattleTransitionAndInitBattleVariables`, which both
+`InitBattleCommon` (`core.asm:6680`, trainers) and `InitWildBattle` (`:6699`)
+call unconditionally - every battle on hardware enters through a wipe. In the
+port only `OverworldState:pushBattle` built one, and `Commands.start_battle`
+pushed the `BattleState` straight onto the stack. The trainer-*sight* path
+went through `pushBattle`, but every **script-driven** battle did not: gym
+leaders, the rival, Giovanni, and every scripted wild encounter cut straight
+to the battle screen with no transition at all. The catch tutorial
+(`old_man_demo`) had the same gap; `InitWildBattle` has no
+`BATTLE_TYPE_OLD_MAN` special case, so it gets a wipe too.
+
+**Beyond 160x144.** Both halves of the transition used to stop at the classic
+letterbox. The flash filled the 160x144 UI canvas, and the wipe handed the
+surrounding window a generic centre-out square cascade
+(`Renderer:drawBattleCascade`) regardless of which of the eight styles was
+running - so at any zoom a spiral read as "a spiral in a box, with something
+else happening around it".
+
+- The flash is a palette write (`rBGP`), and a palette register tints every
+  pixel the LCD shows; there is no "outside the screen" for it to miss. It is
+  now published to the renderer as a screen-space veil and painted over the
+  finished composite, so it covers the whole surface at any zoom.
+- The spiral and circle walks are now generated for whatever grid the window
+  works out to (`BattleTransition.gridOrder`), and the area outside the
+  letterbox is filled in that order instead of the square cascade. The
+  authentic 20x18 builders still own the letterbox itself, overrun and all,
+  so nothing changes at 1x. The generic builders are deliberately *not* the
+  ROM's walk - out there the hardware has no behaviour to be faithful to,
+  only a shape to continue.
+- `shrink`, `split` and the two stripe styles are plain geometry rather than
+  a tile order, so they keep the cascade for now. Extending them is
+  rectangles, not a walk, and has not been done.
+
+Note that the **flash is wild-only**: `BattleTransition_FlashScreen` is called
+from `BattleTransition_Circle` (`:585`) and `BattleTransition_DoubleCircle`
+(`:628`) and nowhere else. A trainer battle's transition is the spiral -
+inward against a weaker foe, outward against a stronger one
+(`wBattleTransitionSpiralDirection`, `:119-126`) - with no flash in front of
+it. The port's `flash` mapping was already correct; the transition simply
+never ran for those battles.
+
+Two of these deserve their reasoning recorded:
+
+**The inward spiral** writes one tile per iteration and calls
+`BattleTransition_TransferDelay3` every seventh tile. That helper is not a
+one-frame transfer - it is `ld a,1 / ldh [hAutoBGTransferEnabled] / call
+Delay3 / xor a / ldh [...]` (`battle_transitions.asm:619`), so the cadence is
+7 tiles per **three** frames. Reading it as one frame runs the whole wipe 3x
+too fast, ~46 frames against the ROM's ~150. pokered-c hit that exact bug and
+caught it on a live comparison.
+
+**The black hold** is not a number pokered states anywhere; it is incidental
+load cost that a modern port does not pay. The derivable floor is ~13 frames
+(`LoadHpBarAndStatusTilePatterns` 4, `LoadHudTilePatterns` 2, `ClearScreen`'s
+`Delay3` 3, the `DisableLCD` LY wait 1, `Delay3` after `EnableLCD` 3), but the
+two sprite decompressors (`UncompressSpriteFromDE` for the 7x7 front pic and
+`LoadPlayerBackPic`'s uncompress + `ScaleSpriteByTwo`) are bit-level RLE/delta
+decoders that cannot be cycle-counted from the asm at all. So the derivation
+bottoms out around 25-30 with an unbounded remainder. pokered-c set 60 by ear
+against the real ROM and marked it ~95% right rather than frame-matched. The
+credible range is 30-60; it should not be "corrected" down toward the floor on
+the strength of the derivation, because the omitted decompressors are exactly
+the unbounded part. Pinning it exactly wants a frame-by-frame capture.
+

+
+The HP bar was the single largest battle divergence. `UpdateHPBar` steps **one
+HP point per loop iteration**; each iteration pays 1 frame in
+`UpdateHPBar_PrintHPNumber` whenever `wHPBarType != 0` - the player's own HUD
+and the party menu, but not the enemy HUD - plus 2 frames for each pixel the
+bar actually moves. The tail (`.animateHPBarDone`, `:132-135`) prints the
+number once more, animates one last pixel and falls into `Delay3`, so it costs
+6 frames player-side and 5 enemy-side.
+
+A 150 HP mon losing everything therefore costs 150 + 96 + 6 = **252 frames
+(4.2 s)** on the player's HUD, against 96 + 5 = 101 on the enemy's. The port
+used a flat `maxHP/96` - the enemy-side rate applied to both sides - and ran
+that same drain in 96 frames (1.6 s).
+
+## Tier 2 - frequent
+
+Status-effect failures (`engine/battle/effects.asm:161,1162,1205`) hold **50**
+frames each. `SwitchAndTeleportEffect` uses 50 and 20
+(`:834-901`). Evolution holds **50** then **40**
+(`engine/pokemon/evos_moves.asm:123,155`). The healing machine
+(`engine/overworld/healing_machine.asm`), item effects
+(`engine/items/item_effects.asm`, 259 frames across 8 sites), and the fishing
+animation (**10** then **100**, `engine/overworld/player_animations.asm:380,399`)
+are all in this tier.
+
+## Tier 3 - set pieces
+
+Highest total budgets in the scan, all seen rarely:
+`engine/movie/hall_of_fame.asm` (529 frames / 7 sites),
+`engine/link/cable_club.asm` (507 / 12), `engine/movie/credits.asm` (502 / 7),
+`engine/movie/trade.asm` (494 / 19), `engine/movie/intro.asm` (317 / 7),
+`engine/menus/main_menu.asm` (271 / 15), `engine/menus/save.asm` (250 / 3),
+`engine/battle/end_of_battle.asm` (200 / 1, the link-battle win/lose string).
+Several of these already have faithful implementations - see
+`src/ui/IntroMovie.lua`, `src/ui/Credits.lua`, `src/ui/HallOfFame.lua`, whose
+constants cite their asm sources directly.
+
+## Status
+
+Closed, and locked by `tests/engine/timing_parity.lua`:
+
+1. **Text page and CONT breaks** - were 0 frames where hardware spends 13-23,
+   on every page of every dialogue in the game. Now exact, including the
+   three-frame pre-input hold that swallows a mashed A.
+2. **Player HP bar drain** - was ~2.5x too fast on a typical mon. Now steps
+   one HP point at a time at the hardware rate, with the enemy HUD correctly
+   cheaper than the player's.
+3. **Warp fade** - was a symmetric 12/12; now 32 out and no fade in, which is
+   both the right duration and the right shape.
+4. **Yes/no answer** - was 0 frames where hardware spends 15, with the cursor
+   snapping to NO on B for the duration as `.choseSecondMenuItem` does.
+
+5. **Battle entry** - every wipe ran at a flat 40/24 against budgets of 30-156,
+   the silhouette slide was 40 frames against 72, the black hold was half
+   what pokered-c calibrated, and the trainer intro's 20-frame gap before the
+   balls and text was missing entirely. This was the single most compressed
+   stretch in the game.
+
+6. **Battle turns** - the type-4 blink ran at 20 frames against 60. That is
+   the applying animation for every plain damaging move the player uses, so
+   it was the single most-repeated timing error in the game. The 30-frame
+   beat that hardware spends on every status move and every miss was missing
+   entirely. The faint slide, unusually, ran *slower* than hardware (30
+   against 14).
+
+Two things worth recording about that last batch, because both contradict a
+plausible reading:
+
+- **`PrintCriticalOHKOText`'s 20-frame hold is not conditional.** The
+  "no critical hit" early-out at `core.asm:3799` jumps to `.done`, and
+  `.done` *is* the `ld c, 20 / jp DelayFrames`. Every landed hit pays it,
+  which is where the beat before "It's super effective!" comes from.
+- **`StartBattle`'s 40-frame hold is not conditional either.** The `call nz`
+  at `core.asm:154` gates only `EnemySendOutFirstMon`; the `DelayFrames 40`
+  under it runs for wild battles too, and it lands *between* the enemy's
+  send-out and `.playerSendOutFirstMon` (`:166`) rather than at the end of
+  the intro.
+
+Trainer victory (24-frame scroll-in + 40-frame hold) and the ball shake
+(`SFX_TINK` + `DelayFrames 40` per rock) were already correct -
+`BattleState.lua`'s `wait = 64` and `AnimPlayer.lua`'s `emit(40)`. Note that
+pokered-c's `BUI_TRAINER_VICTORY_SLIDE` comment calls the scroll-in 14
+frames; `_ScrollTrainerPicAfterBattle` is 6 loop passes of `DelayFrames 4`,
+so 24 is right and this port already had it.
+
+**Leaving a battle was a cut, not a fade.** `EnterMap` checks
+`BIT_BATTLE_OVER_OR_BLACKOUT` and calls `MapEntryAfterBattle`
+(`home/overworld.asm:22`), which is `GBFadeInFromWhite` - so the map fades up
+from white over 24 frames, behind the 10-frame hold at `:351-352`. The port
+popped the battle and the overworld was simply there. `Transition.battleReturn`
+supplies both halves, and steps the veil in three palette stages of 8 frames
+rather than tweening it, because `GBFadeIncCommon` writes a palette and holds
+it with `ld c, 8 / call DelayFrames` (`home/fade.asm:30-41`) three times over.
+
+It is wrapped around `battle.onFinish` in `OverworldState:pushBattle` - the
+one funnel every battle goes through - rather than living in `afterBattle`.
+That placement matters: a script-driven **win** defers `afterBattle` into
+`ctx.afterScript` so an evolution screen cannot be buried under the trainer's
+follow-up text (`Commands.start_battle`), and a fade inside `afterBattle`
+inherited that deferral. On a rival battle it fired after the post-battle
+dialogue *and* the rival's walk-off, rather than when the battle ended.
+
+The rest of `onFinish` runs as the fade's `onDone`, which is also the hardware
+order: `MapEntryAfterBattle` fades the map back in and only then does the map
+script run. The overworld is frozen meanwhile - `StateStack` updates the top
+state only - so nothing moves under the white.
+
+Hardware skips the fade on a dark map (`wMapPalOffset` nonzero takes the
+`LoadGBPal` branch at `:754`). This port has no `wMapPalOffset` equivalent -
+no map needs FLASH to be lit - so that branch is unreachable here;
+`battleReturn` accepts `opts.instant` for it if that ever changes.
+
+Still open, hardware number confirmed but not yet wired:
+
+- List menu open (10) and per-input redraw (`Delay3`).
+- Every battle-table row marked "unmeasured" above - the status/miss beat (30)
+  is the highest-exposure of them, since it is paid on every status move and
+  every miss.
+
+Entries marked "unmeasured" have confirmed hardware numbers but the port side
+has not been traced; they are remaining work, not known-good.

+# Gen1Recomp Xbox UWP build notes
+
+This is the Xbox Dev Mode package for Gen1Recomp.
+
+The rough shape is:
+
+- `Gen1RecompUWP.exe` starts LÖVE through SDL's WinRT wrapper
+- the bundled LÖVE 11.5 UWP backend provides LuaJIT and the Xbox file picker
+- the bundled SDL2 runtime contains the Xbox controller mapping
+- ANGLE provides OpenGL ES over D3D11
+- the bundled runtime contains the audio, font, video, and compression libraries
+
+## What You Need
+
+The tested toolchain is:
+
+- Visual Studio 2022 17.14
+- MSVC v143 x64/x86 build tools
+- C++ Universal Windows Platform tools
+- Windows 11 SDK `10.0.26100.0`
+- CMake 3.24 or newer
+- Git for Windows
+- Info-ZIP `zip` and `unzip`
+
+Use Visual Studio Installer to add **Universal Windows Platform development**, the v143 C++ tools, CMake tools for Windows, and Windows SDK `10.0.26100.0`.
+
+The x64 UWP dependencies are committed under `third_party`. Their versions,
+source revisions, licences, and hashes are recorded in `third_party/manifest.json`.
+No additional checkout or environment variable is required for a normal game
+build.
+
+## Rebuild the Dependencies
+
+Run the dependency rebuild from the repository root:
+
+```powershell
+.\scripts\xbox-uwp\rebuild_dependencies.ps1
+```
+
+The script clones the pinned SDL2, LÖVE, LuaJIT, vcpkg, depot_tools, and ANGLE
+sources when they are missing. It applies the Xbox SDL2 patch, builds the x64
+UWP Release libraries, stages the required DLLs, import libraries, headers, and
+licences under `third_party`, updates every SHA-256 entry in the manifest, then
+builds the Release MSIX.
+
+The generated source checkouts are ignored by Git. A fresh ANGLE sync is about
+10 GB, so allow at least 20 GB of free disk space for all sources and build
+outputs. Use `-SkipAngle` to retain the existing pinned ANGLE runtime while
+rebuilding SDL2, LÖVE, LuaJIT, and the vcpkg libraries. Use `-SkipPackage` when
+only the dependency bundle needs to be refreshed. The rebuild stops if a source
+checkout has local changes. Remove that generated `source` directory to restore
+the pinned revision.
+
+## Build the MSIX
+
+Run the Xbox build from Git Bash at the repository root:
+
+```bash
+scripts/build_xbox_uwp.sh --release --version 1.2.3
+```
+
+The build uses `scripts/pack_love.sh` to create and verify the same ROM-free
+`game.love` payload used by the other release targets. It then links the UWP
+host and stages LÖVE, LuaJIT, SDL2, ANGLE, and the vcpkg runtime DLLs.
+
+Use `--relwithdebinfo` for a package with symbols. To package a `.love` produced
+by another build or downloaded from CI, pass `--game-love path/to/game.love`.
+The upstream `X.Y.Z` release becomes `X.Y.Z.0` in the generated MSIX manifest.
+Neither the manifest template nor `src/core/Version.lua` is edited in place.
+
+The manifest publisher must match the signing certificate subject. Pass it
+when preparing a signed package:
+
+```bash
+scripts/build_xbox_uwp.sh --release --version 1.2.3 \
+  --publisher "CN=Gen1Recomp"
+```
+
+The normal build is unsigned. Release CI supplies the private PFX and password
+from `XBOX_UWP_SIGNING_CERTIFICATE` and `XBOX_UWP_SIGNING_PASSWORD`; neither may
+be committed. The public certificate is safe to include with the release.
+
+Run the offline packaging checks from Git Bash:
+
+```bash
+bash scripts/xbox-uwp/selftest_build_xbox_uwp.sh
+```
+
+## Build Output
+
+Visual Studio package output lands under:
+
+```text
+ports\uwp\build\release\AppPackages\Gen1RecompUWP
+```
+
+The build also stages the distributable archive and checksum under:
+
+```text
+dist\xbox-uwp\gen1recomp-X.Y.Z-xbox-uwp.zip
+dist\xbox-uwp\gen1recomp-X.Y.Z-xbox-uwp.zip.sha256
+```
+
+The archive contains the MSIX, framework dependencies, build provenance and,
+for a signed release, the public certificate. The third-party notices are
+packaged inside the MSIX. Install the MSIX and dependency packages through
+Xbox Device Portal.
+
+## Runtime Data
+
+The package contains no ROM, generated cache, save or mod data. The Xbox file
+picker copies user-selected files into LocalState and the launcher imports them
+from there. Saves, ROM cache and installed mods remain under the LÖVE save
+directory in LocalState.
+
+LuaJIT requires the `codeGeneration` capability. `removableStorage` exposes
+external media to the Xbox picker. The network capabilities support relay play
+and direct hosting. The package does not request full trust or broad filesystem
+access.
