Does anyone know if Gameshark codes or action replay codes screw your game up? I really want one because I want Deoxys and Jirachi and Mew. But I won't get it if it screws my game up
some codes might mess up your game but it if you turn it off it like nothing ever happened.Also I tryed the mew code it worked and my game did not crash.so it is ok to get one.
can you give gameshark codes please
What codes do you need?
