KIMITRANCE -- To enter the codes, you need a Gameshark or Action Replay system, (which is purchased seprately from the GBA and the games,) you can usually find them in most places that sell video games. then turn on your GBA after plugging your Gameshark/Action Replay into the game slot, and the game into the slot on the GS/AR. a new screen should come up and you can enter the cheats from there.
devinechaos3 -- if it is the button that isnt working, just try wiping it down with a moist paper towel, (BE SURE TO WRING OUT ANY EXCESS WATER, YOU DONT WANT TO FRY YOUR SYSTEM BY GETTING IT TOO WET DO YOU!) and just go around the edges of the buttons with it... if it is the circutry, the only thing i can think of is either getting a new one, or getting the existing one fixed.
Hope I helped...
