Game Shark Codes
Warning: Using Game Shark on your game might do harm to your game. It might erase your saved game, cause glitches (such as not being able to battle a gym leader when you are suppose to), etc. Nintendo does not endorse Game Shark. Pokemon Gold/Silver Game Shark is especially unstable. Nor Nintendo or Game Shark (or this website), is reliable for any harm to your game. I highly do not recommend using Game Shark if you don't want to take the risks. Use with caution.
