To use Action Replay for Mario and Luigi, first, insert the Action Replay cartridge into the Nintendo DS or Game Boy Advance console, then insert your Mario and Luigi game cartridge into the Action Replay. Turn on the console and follow the on-screen prompts to input or select cheat codes for the game. Once you've activated your desired cheats, start the game, and the cheats will take effect.
