It's likely you're thinking of a specific game, but you haven't provided any details about the game or system.
To help you find the correct information, please tell me:
* What game are you playing? (e.g., Pokemon, Final Fantasy, etc.)
* What system are you playing on? (e.g., Game Boy, PlayStation, etc.)
Once you provide this information, I can assist you in finding any available cheats for that game.
