Boss Rally / Top Gear Rally: matching decompilations and native ports

Boss Rally / Top Gear Rally reconstructs the PC and N64 games as C source checked against their original machine code. The author reports that all 572 functions of the N64 release match byte for byte, while the Boss Rally PC work remains partly matched. Rally Builder creates native builds from users’ BIN/CUE or ROM copies.

Requirements & limits

Prerequisites: A user-owned Boss Rally BIN/CUE or Top Gear Rally ROM is required for a native build.
Limits: The author reports that Boss Rally’s byte-exact matching remains incomplete.
License: The project’s own tools and port code are under CC0-1.0; its reconstructed game code is outside that dedication.
