Retro Launcher

You can run this title standalone (release zip + the built-in recomp-ui Generate & Build flow), or manage installs, updates, ROM/BIOS wiring, and queued builds more intuitively with Retro Launcher — the Retro Compilation Manager hub for self-compiling recomps.

Retro checks for updates, rebuilds with existing build data when possible, shares the portable toolchain used by per-title launchers, and automates BIOS/ROM/save plumbing so you are not stuck repeating each game’s wizard by hand.

Legal

You must own the original game. Disc images under disc/ are gitignored and must never be committed. Retail BIOS dumps are not redistributed; OpenBIOS is used for Generate unless you supply your own SCPH locally.

Optional box art under launcher_assets/img/ may come from libretro-thumbnails (Named_Boxarts); see BOXART_SOURCE.txt when present.

Quick start (dev)

git submodule update --init --recursive
./psxrecomp/tools/ci/build_emitters.sh
python3 psxrecomp/psxrecomp_cli.py generate \
  --config game.toml --project-root . --disc disc/<your>.cue
cmake -S . -B build-release -G Ninja -DCMAKE_BUILD_TYPE=Release
cmake --build build-release --target psx-runtime

Zip prefix for CI artifacts: msx.

Symbols

Progressive map: symbols.toml → python3 tools/sync_symbols.py → psx_symbols.h (PSX_FN_*). See psxrecomp/docs/SYMBOLS.md.

Framework pins

Submodule gitlinks (psxrecomp, optional recomp-ui, nested recomp-net) are authoritative. framework_pins.txt is an optional scaffold snapshot; release CI logs SHAs with record_pins.sh but builds whatever the gitlinks resolve to. Bump submodules deliberately — do not float on main/master in release CI.
