# Monster Hunter Tri: a matching Wii decompilation

> Monster Hunter Tri is an in-progress matching decompilation of the USA Wii release RMHE08 in C and C++. Its build links matching reconstructed units with original bytes for unfinished regions, then checks main.dol against a recorded SHA-1. The project tracks split translation units, symbols and per-function scores, and documents compiler-matching techniques and build checks.
