NES "100-in-1" Cartridge? (Multi-Carts Explained – Unlicensed & Modern)

No licensed NES cartridge contained exactly 100 games. However, unlicensed multi-carts (common in Asia, Brazil, Eastern Europe) packed dozens–hundreds of games via bank-switching mappers.

Notable Multi-Carts

• 150-in-1 / 200-in-1 / 76000-in-1 – mostly duplicates, hacks, tiny homebrews.
• Action 52 (1991) – 52 original games; infamous for quality.
• Caltron 6-in-1 / Myriad 6-in-1 – 6 games.
• Super Game / Supervision 100-in-1 – Famicom format, 60-pin.

Legitimate Multi-Game Carts

• Nintendo World Championships 1990 – 3 games (Mario, Rad Racer, Tetris) timed.
• Donkey Kong Classics – DK + DK Jr.
• Mario Bros. / Duck Hunt combo – 2 games.

Modern flashcarts (EverDrive N8 Pro, FXPAK Pro) hold full libraries on SD – the true "∞-in-1".
