Action replay code for Pokemon black to clear wonder cards?

[TrainerBZ]

I used a wonder card code incorrectly and now whenever I check my wonder card album, the screen all of a sudden turns black. I can still hear the music playing, it's just that the screen is black and I can't exit out so I can no longer see my wonder cards. I'm not playing an emulator, I'm playing a real game cart. I know the corrupted data is in my Wonder Card Album so all I need to fix this problem is to clear my wonder card album. But I don't want to reset my game. It has hundreds of hours of hard work on there so what I need is an Action Replay code for clearing all the Wonder Cards in my Album. Does anybody have that code or could please make one? Someone please help me, it would be very appreciated.
