I used my action replay put in the id and stuff

Did you know that using some codes can cause damage to your game? Official codes and codes tested through emulation are the only ones you should ever use. If the game still works fine without the code, or without your Action Replay, then you should be okay.

Try disabling other codes when using the one you put in for yourself. If it fails, double check the code. If you need to, use the software that comes with the Action Replay to put the code in via copy/paste. If this still doesn't work, the code is bad, or is not for your region.
