Ships a dual-NRO native launcher that checks GitHub Releases, updates both NROs from gen1recomp-*-switch.zip with matching NACP versions, and stays silent unless an update needs confirm.
2.1 KiB
Native Switch OTA launcher
In-console updates for Gen1Recomp on Nintendo Switch. This NRO is the hbmenu
entry (gen1recomp.nro). It checks GitHub Releases quietly (no console flash
when you are already up to date or offline). Only if a newer release exists
does it prompt to download the same gen1recomp-*-switch.zip used for install,
verify SHA-256 from sha256sums.txt, replace both gen1recomp-game.nro
and gen1recomp.nro (matching NACP version for hbmenu/Sphaira), then hand off
with envSetNextLoad.
The LÖVE self-updater (src/update/Check.lua) stays disabled on NX.
Protocol contract (also in Lua): src/update/SwitchOta.lua.
NACP icon: assets/switch/icon.jpg.
Layout on microSD
sdmc:/switch/gen1recomp/gen1recomp.nro ← this launcher
sdmc:/switch/gen1recomp/gen1recomp-game.nro ← fused LÖVE game
sdmc:/switch/gen1recomp/version.txt ← installed X.Y.Z
sdmc:/switch/gen1recomp/pokemon-love2d/ ← saves (never touched by OTA)
Host tests (no DEVKITPRO)
cd native/switch-ota-launcher
make host-test
Switch build (DEVKITPRO)
Needs DEVKITPRO with packages roughly:
(dkp-)pacman -S --needed switch-curl switch-mbedtls switch-zlib switch-zziplib
# or: bash scripts/switch/install_devkitpro_deps.sh
export DEVKITPRO=/opt/devkitpro # typical
cd native/switch-ota-launcher
make
# → gen1recomp.nro
Or from repo root:
scripts/switch/build_ota_launcher.sh
Docker fallback uses the same pin as fused builds (scripts/switch/dkp-docker.image).
Packaging
scripts/switch/pack_sd_zip.sh GAME_NRO VERSION OUT_ZIP LAUNCHER_NRO writes both
NROs into the SD zip. That zip is also the OTA download asset (unified).
Manifest: scripts/switch/ota_launcher.manifest.
Status / known gaps
- Zip extraction uses
switch-zziplib(ota_unzip.c) on device. - OTA replaces launcher + game from the unified zip (NACP versions stay aligned).
- Sphaira HOME forwarders cache metadata until reinstalled (see docs/switch-install.md).
- Install toolchain deps once:
bash scripts/switch/install_devkitpro_deps.sh
