Game Genie (Nintendo NES, 1990) is the original cheat device that let you bend reality before the GameSharks and Action Replays of the world ever existed. Want infinite lives in Contra? Moon jumps in Mario? Invincibility in games that already hate your existence? This little gold-plated brick had your back.

Slide it into your NES, insert a game on top, punch in some mystical alphanumeric codes, and boom — your childhood just got a whole lot easier (or weirder). Half the fun was experimenting with random codes and seeing how badly you could break the game.

1. Cheat Like It’s 1990: Gain infinite lives, unlock hidden content, and mess with physics in your favorite NES games.
2. Compatible With Most Titles: Works with hundreds of NES games — from Castlevania to DuckTales.
3. Physical Code Book Included (if present): A relic of gaming history full of glorious exploits and wonky fonts.
4. Plug-and-Play Chaos: No modding, no soldering — just pure cartridge-stacking madness.
5. Essential Retro Collectible: Whether you used it for good or evil, it’s a must-have for any NES fan or retro collector.
