Cheating in Pokemon games usually involves specific codes or modifications that can be entered using devices like Game Shark or Action Replay. However, these devices are not compatible with the original Game Boy version of Pokemon Yellow.
It's important to note that using cheats can detract from the experience of playing the game. They can break the balance of the game, make it less challenging, and potentially lead to bugs or crashes.
Enjoy Pokemon Yellow by playing the game the way it was intended!
