Bakugan game not saving

when ever i play this game on my ds (it is a itouch game card but m3 ds real format) it wont let me save or takes ages... i downloaded the U game on romulation and *Other Site* but it wont let me save. it just says:
Saving...
Please do not turn power off or remove the game card
...please help me...

Try looking through the Common Issues thread.
