Play Game Genie (Unl) Online

Game Overview

Remember the Game Genie? That weird little cartridge you'd plug your NES game into before shoving the whole stack into the console? This ROM perfectly recreates that nostalgic cheat code screen—the one where you'd frantically enter random letter combos from the booklet (or that one kid at school swore worked).

Suddenly, Mario could fly forever, or Link started with the Master Sword, or—if you got really creative—you'd completely break the game in hilarious ways. People even hacked entire new experiences out of old games using these codes. It's all here: that same janky magic of bending the rules before the title screen even loads.

Just don't tell your younger self how much easier this makes Battletoads.
