ra2-decomp: a matching decompilation of Yuri's Revenge

ra2-decomp reconstructs Command & Conquer: Red Alert 2 – Yuri's Revenge 1.001 as C++ and checks compiled functions against gamemd.exe byte for byte. It maps function addresses, source files and hashes, while recording unmatched attempts separately. The author reports 79% of the game's code bytes matched as of 6 November 2026.
