# Pac-Man NES Source Reconstruction: seven byte-identical cartridge revisions

> Pac-Man NES Source Reconstruction rebuilds seven official Famicom and NES Pac-Man revisions from shared, annotated 6502 ca65 modules. Its build rules extract data from a user's ROM and compare assembled output byte for byte with each available original; a relocated build also has a recorded longplay check in MAME.
