wanwan

rollback launcher for fighter maker games (fm2k/fm95). fm95 support not finished yet. spawns the game and injects a hook dll that does the save-state rollback, online play, spectating and replays. windows 32-bit only, cross-compiled from wsl/linux with mingw-w64 (i686) -- injection + the 32-bit game abi are why. native linux isn't wired up.

build

need wsl2 or linux with the i686 mingw toolchain:

sudo apt install -y gcc-mingw-w64-i686 g++-mingw-w64-i686 binutils-mingw-w64-i686 cmake ninja-build git

then:

git clone --recursive https://github.com/Armonte/wanwan.git
cd wanwan
./make_build.sh    # inits submodules + runs cmake
./build.sh         # compiles, stripped binaries land in dist/

forgot --recursive? make_build.sh self-heals it. gekkonet and the one kgt parity header are vendored in-tree as plain files so they need no submodule step. SDL, SDL_image, imgui, minhook and miniupnp are submodules make_build.sh pulls for you (and only the jpeg/png/tiff image codecs, not the big unused avif/jxl/webp ones).

outputs land in dist/: FM2K_RollbackLauncher.exe, FM2KHook.dll, FM95Hook.dll, FM2KUpdater.exe. unstripped copies with full debug info stay in build/ for symbolication. build/ is incremental, don't nuke it between builds.

run

drop the launcher + both hook dlls in a folder, point it at your fm2k games, go. both dlls ship together so it picks the right one per engine (fm2k vs fm95/cpw). deeper notes in docs/.

deploy (maintainer only)

go.sh builds then copies into my local windows games tree (/mnt/c/games). that half skips itself on any machine without that tree, so go.sh just builds for everyone else. the normal flow is make_build.sh && build.sh.
