Extracting 20+ NES & Famicom ROMs from Animal Crossing

A Python script demonstrates how to extract 21 NES and Famicom ROM files from Animal Crossing GameCube ISO files. The ROMs are compressed using Nintendo's Yaz0 compression scheme and can be identified by their magic headers. The extracted ROMs, worth over $500 if purchased separately, can be played on modern emulators while maintaining legal ownership through the original Animal Crossing disk.
