M2 
IMSA World Championship Racing
rsantos722/imsa-wcr-m2-recomp
A native Windows, macOS, and Linux port of IMSA presents World Championship Racing, a racing game that never came out because the Panasonic M2 was cancelled in 1997, and of shooter2d, the other game on the same disc. It’s a static recompilation with its own recompiler, which translates the game’s PowerPC 602 code to C, on top of its own program standing in for the console (SDL3, with OpenGL 3.3 or a software renderer); MAME’s M2 driver served as a reference for the graphics chip. The README calls it fully playable and stable, with some graphics and performance issues left to polish. It aims to stay faithful to the original and offers three control profiles (the original, a patched one that makes the game’s own settings work, and a custom one), analog control rebuilt from scratch, fixes, enhancements, and features the game left unfinished, all optional. The launcher installs the game, handles graphics, controls, and saves, starts IMSA or shooter2d directly, and has a 3D car viewer. v1.0.1 (November 6) is the latest of 2 releases.
