Pokemon white freeze

Hello,I have defeated the elite four and than im in the castle where the pokemon zekrom is.
If i talk to him the game is freezing but the ingame music is playing normally ?How can i fix this problem ?

Might be because you have too many cheats on, try turning off the ones you don't need to run the game.

Thanks it works now :)

Works!!

I did have a lot of cheats on, but disabling them did nothing to fix it.
Is it a problem that I've been saving using DeSmuME states instead of actual in-game saves?Also I saved the state while Zekrom is saying "Bazzazzazzash" is that part of the problem?I really don't want to load from the last in-game save, I'd have to restart the whole game (that save was in the bedroom just after the first Pokemon battle)
