for some reason, any codes that my pokesav generates (i also tried pokegen) or any i recieved online that had been tested that are made to replace pokemon in your party have not been working for me. i'm not sure if its my Action Replay (DSi) or if i'm missing a master code. tho, it may be that my L and R buttons do not work. im not sure. but if anyone has any input or advice it would be greatly appreciated.
