Swapping GB carts from the Game Boy to our advantage

The beauties (and crashes) of CartSwap

CartSwap (Cartridge Swapping) is a technique that allows ACE in any Game Boy game, even before the game has actually booted up! Example applications include :

  • Spoofing consoles (Pokémon Crystal can run on the Gray Brick!)
  • Speedrunning games quicker than a TAS
  • Gaining ACE on games that are otherwise ACE-less
