# Madden Football 64: matching Nintendo 64 decompilation

> Madden Football 64 decompilation reconstructs portions of the USA Rev 0 Nintendo 64 game's code and maps its packed ROM layout. Build commands recover the resident program, compare compiled C units byte for byte with retail code and track assembly references separately. The author reports 19.60% of whole-program code as matching decompiled C at the documented snapshot.
