Three runtime bugs were fixed during bring-up on psxrecomp v0.3.2-alpha — a boot freeze, a dead in-game controller, and the "return to Mode Select" black screen (a live-traced SR-register bug in the shared TCB scheduler). Full write-up: see Port report below.

Requirements

• Retail BIOS (SCPH-1001, US, 512 KiB, CRC32 37157331). This title is set openbios = false — OpenBIOS is not compatible with it. Point the first-run wizard (or bios.cfg) at your own legal dump.
• Your own legal disc image (.cue / .bin). Disc images are never committed.

Notes

• 120 Hz+ monitors: game.toml sets [video] vsync = "off" so the 59.94 Hz wall-clock pacer owns the frame rate. Without it, letting vsync drive cadence on a high-refresh panel runs the game at 2×.
• Controller: SF EX2 Plus is a digital-pad title. p1_mode must be digital — analog / DualShock mode makes the game ignore all input. Multitap should be off for a normal 1v1.

RetComM 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 RetComM Launcher — the Retro Compilation Manager hub for self-compiling recomps.

Downloads · Full README & features

RetComM 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 and are never committed — supply your own SCPH-1001 dump locally (this title requires it; OpenBIOS is disabled).

Default app icon: assets/psxrecomp.ico (and .png / .svg) — RetComM-themed controller mark from psxrecomp/assets/. Windows builds embed it via APP_ICON.

Box art (launcher_assets/img/boxart.tga) is used by the launcher.

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 \
  --bios /path/to/SCPH1001.BIN
cmake -S . -B build-release -G Ninja -DCMAKE_BUILD_TYPE=Release
cmake --build build-release --target psx-runtime

Zip prefix for CI artifacts: sfex2p.

Symbols

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

Framework pins

Submodule gitlinks are authoritative. psxrecomp points at strider973/psxrecomp branch sfex2p-v032 — v0.3.2-alpha plus the two SR/TCB scheduler fixes from bring-up (09ff2311, 36e124d3); recomp-ui tracks upstream mstan. 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.
