+## Portable Mode
+
+By default the game keeps your save, options, and the private ROM-derived
+data cache in your OS's normal per-user app data folder. To keep everything
+next to the game instead (handy for a USB stick or portable drive you carry
+between computers), drop an empty file named `portable.txt` next to the app
+(next to `PokemonRed.app`/`.exe`, or next to `main.lua`/`conf.lua` when
+running from source), then launch the game. Portable mode is desktop-only
+(Windows, Linux, macOS); it has no effect on Android or iOS, where the app
+runs from a read-only package.
+
+With `portable.txt` present:
+
+- `save.lua`, `save.lua.bak`, and `options.lua` are read from and written to
+  that same folder instead of the OS save directory.
+- A ROM import writes the generated `data/generated` and `assets/generated`
+  cache straight into that folder too (nothing is left in the OS save
+  directory), so a later launch reuses it without asking for the ROM again
+  even on a different computer, as long as the same folder comes along.
+- Deleting `portable.txt` switches back to the normal OS save directory; nothing
+  already written to either location is touched automatically, so copy files
+  over yourself if you want to carry existing progress across the switch.

+## Reimplemented unused Prof. Oak and Rocket Chief battles
+
+The original ROM defines trainer data for `PROF_OAK` and `CHIEF`
+(`data/trainers/parties.asm`) but never attaches either to an NPC, so
+both battles are unreachable in the real game. This project makes them
+fightable after the Hall of Fame:
+
+- Prof. Oak battles you in Pallet Town once `EVENT_BEAT_CHAMPION_RIVAL`
+  is set, using `ProfOakData`'s three starter-matched teams (the team is
+  picked by the type that counters your starter, mirroring the rival).
+- The Celadon Game Corner Chief battles you in his house post-game.
+  `ChiefData` is empty in the ROM, so `OPP_CHIEF` is given a
+  reconstructed party.
+
+This is an intentional divergence: neither battle can be triggered in the
+original game.
+
+## Reimplemented unused Silph Co. card-key doors
+
+`engine/events/card_key.asm` and the unused `CardKeyTable1/2/3` coordinate
+lists (`data/events/card_key_coords.asm`) describe locked doors for Silph
+Co. floors 2F-11F, but no retail `.blk` map layout ever places the closed
+door block at those coordinates, so the card key check is dead code in
+the original game. This project stamps the closed door block (`$54`/`$5f`
+on floors 2F-10F, `$20` on 11F) over each of the 20 door coordinates on
+map load, and swaps it for the open block once that door's
+`EVENT_SILPH_CO_n_UNLOCKED_DOORn` flag is set (using the key from a Team
+Rocket grunt, as in the original's unused design).
+
+This is an intentional divergence: the doors are not visible or
+functional in the original game. The door layout lives in
+`tools/rom_manifest.json` (`field.cardKeyDoors.closedDoors`), hand-ported
+since no retail ROM data encodes it; `src/import/RomExtractor.lua` copies
+it straight through on ROM import.

+The console understands these verbs (anything else is evaluated as Lua):

+- `give ID [n|level]` — add an item (count) or a Pokémon (level).
+- `flag NAME [on|off]` — read or set an event flag.
+- `party` — dump the current party.
+- `mods` — list loaded mods and their state.
+- `reload` — hot-reload mods (same as `F5`).
+- `trace PAT | trace off` — trace events/hooks matching a glob pattern.
+- `help` — list the verbs.

-- Parity test, Viridian City's two old men + the Pokédex object swap.
--

--
--   object_event 18, 9, SPRITE_GAMBLER_ASLEEP, STAY, NONE,       ..._OLD_MAN_SLEEPY

--
-- The sleeper only ever grumbles "private property" and shoves you back
-- down; he never wakes, moves or hides.  The coffee ask and the catch
-- tutorial belong to the walking man, who starts OFF
-- (data/maps/toggleable_objects.asm) and is swapped in for the sleeper
-- when Oak hands over the Pokédex (scripts/OaksLab.asm:602-606).  The
-- north corridor is gated on EVENT_GOT_POKEDEX at exactly (19,9)
-- (ViridianCityCheckGotPokedexScript), not on either man's visibility.
--
-- All three of those were wrong at once: the port merged both men into
-- the sleeper, never ran the swap (so the walking man stayed hidden for
-- the entire game), and gated the corridor on the sleeper being hidden --
-- which made talking to him and answering "yes, I'm in a hurry" the only
-- way out of Viridian.  Self-contained; run via `luajit tests/parity_viridian.lua`.
