Well hers a piece of info for you The action replay needs a game ID to say where the codes go to not a game name There are official game ID's at codejunkies though i don't know where cause there gay ================================== Also not all codes will just work e.g. not all or some codes made for an American versions will not work with an Australian version or Japanese version
