Gundam Wing Endless Duel Recomp

Gundam Wing Endless Duel Recomp

A native recompilation of Gundam Wing Endless Duel (JPN), built on snesrecomp.

It is the year After Colony 195, and war between the Space Colonies and Earth has begun. To give the colonies an edge, they send 5 young soldiers, trained to perfection, to earth in the most powerful of Mobile Suits-Gundams. With their arrival, the tide of the war changes as they battle against the Earth forces and the Colonies of their origin.

You must legally own a copy of the game. No ROM data is distributed with this project, in the repository or in any release. The recompiled C is generated locally from your own copy and is never committed.

Status

The original Japanese game boots and runs through assisted story matches. Widescreen and localization remain optional mod packages. See the coverage survey below for the tested scenes and current validation limits.

ROM identity

File	Shin Kidou Senki Gundam W - Endless Duel (Japan).sfc
Publisher	Bandai
Year	1996
Mapping	lorom
Region	JPN (Japan)
Coprocessor	none
CRC32	c0aecdca
SHA-256	dd94308d822636c6ddf73c5e2644c84f2eb8fb4d9201150fc5f37d44d6f423f1

tools/regen.sh refuses to run against anything else, so a mismatched revision fails immediately instead of producing subtly wrong output.

Build

git submodule update --init --recursive
bash tools/regen.sh --rom /path/to/Shin Kidou Senki Gundam W - Endless Duel (Japan).sfc
cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build -j

The ROM does not have to live in the repository — keeping it on your own drive is the better habit, and SNESRECOMP_ROM sets the path once for a shell. tools/regen.sh also finds Shin Kidou Senki Gundam W - Endless Duel (Japan).sfc at the repo root if you prefer that; .gitignore blocks it from ever being committed either way.

tools/regen.sh verifies the ROM, generates src/gen/*.c, and re-syncs recomp/funcs.h. Re-run it whenever you change anything under recomp/.

Releases are setup packs

A release zip does not contain the game — nothing derived from the ROM ever does. It contains a setup host (this executable built with -DSNESRECOMP_SETUP_HOST=ON, i.e. without recompiled code), the recompiler, and this source tree. On first run the launcher takes your ROM, generates, rebuilds into build/, and relaunches into the real game. The build tools (the retcomm cmake-clang-v1 pack) are embedded in the zip, or downloaded once per machine if you chose a lean pack.

To produce one locally:

cmake -S . -B build-setup -DCMAKE_BUILD_TYPE=Release -DSNESRECOMP_SETUP_HOST=ON
cmake --build build-setup -j
scripts/package_release.sh build-setup linux-x64 [--embed-toolchain]

src/gen/ must be empty for that configure; the framework refuses to build a "setup" host from a tree that has generated C. .github/workflows/release.yml does the same for four platforms.

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.

Downloads · Full README & features

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.

Porting from here

The scaffold stops where the game-specific work starts. In rough order:

1. Make it boot. src/game_rtl.c holds the frame driver. The generic LLE-first shape is there; a real title usually needs a frame boundary and NMI delivery that understand its own main loop. This is the bulk of the work.
2. Name things. Add entries to recomp/symbols.toml as you identify routines, then re-run tools/regen.sh. Set emit = true to promote one into ahead-of-time codegen; leave it false to keep it interpreted.
3. Resolve dispatch misses. After every run, deal with unresolved indirect targets before anything else — they are the reason a port diverges, and they are cheap to fix early.
4. Never synthesise a result to get past uncovered code, and never edit src/gen/ by hand. Fix the config or the framework and regenerate.

Multiplayer

Two players, one controller per port.

Netplay is built with rollback available (SNES_NET_MODE=rollback); See snesrecomp/docs/ROLLBACK.md.

License

This project's own source is under the license in LICENSE. The framework carries its own terms — see snesrecomp/LICENSE and snesrecomp/THIRD_PARTY_ATTRIBUTION.md. Neither covers the game data, which is not distributed here.

Coverage survey and regeneration

Game-owned generation policy is in recomp/generate.toml; the shared framework runs the same hooks for tools/regen.sh and launcher rebuilds. See the 2026-10-18 coverage survey for verified ROM identity, observed scenes, corrections, and remaining validation limits.
