Mario Kart: Super Circuit - Character Modifier CodeBreaker Codes (USA)
This page contains CodeBreaker cheat codes for Mario Kart: Super Circuit (USA). If you're playing on an emulator you can usually input codes very easily by accessing a tab off the top of the toolbar. Anyone playing on a physical Gameboy will need to purchase a physical CodeBreaker device to use these codes.
If you're using an emulator and still can't figure out how to setup these codes, you're in luck! There's two common emulators for GBA games, the mGBA and VisualBoy Advance. Follow the link provided for the emulator you're using to be taken to a guide explaining how to get these codes working.
