Lego Rock Band

Hey - I was wondering if there was a patch or anything for Lego Rock Band... I can open the file on my DS, but once I get so far it freezes... :-\

What flashcard do you use? With what FW? And which version of game you tried?I have Acekard 2 with Akaio 1.5 and playing USA version of this game, and have NO PROBLEMS...
