Learning to reverse engineer MechWarrior 3

The full story

This unofficial fan rebuild makes MechWarrior 3 (1999) run on Windows 10 and 11, macOS and Linux without Wine or DirectX wrappers. It isn't a remake. The original Mech3.exe (patch 1.2) was taken apart with REA and rewritten function by function in C++, mostly checked against the original running in an emulator, so it plays as it always did but without the old bugs.

You need your own copy, as an installed game, the disc or a disc image (a .cue image also gives you the music). It uses Direct3D 12 on Windows and Metal on Mac. The author describes it as a personal learning project.
