# Goemon's Great Adventure: a matching Nintendo 64 decompilation

> Goemon's Great Adventure reconstructs the Nintendo 64 US game's code as C and supplies tools to rebuild its ROM from a user-provided copy. The author reports that the reconstructed ROM matches the original byte for byte and that all 5,838 game functions match at the instruction level. The build extracts assets from the user's ROM and rebuilds them alongside the code.
