Been reverse engineering the GameCube save file format for NFL Blitz Pro. Mapped the full 40-byte player record structure, cracked the checksum algorithm, and built a Python pipeline that rewrites the roster directly in the .GCI memory card file — no disc modification required.

End result: all 32 teams updated with current 2026 players, stats, positions, and jersey numbers. Runs on real hardware and Dolphin.

Still early — commentary audio matching is the next unsolved problem. Looking for collaborators if anyone's into this kind of thing.
