Mario and Sonic at the Olympic Winter Games Freezes at Winter Island!

Everything goes fine on this game, but when I want to go to Ice Peak on Winter Island the game freezes. It doesn't freeze immediately when I go to Ice Peak, but when the movie comes (when they show the town). I patched it a few times but it still freezes! Can somebody help? (I have the American version)

best of game

That didn't really help me x3

The pacth that i used is an unpatched version of the game with TT menu. It SHOULD work on R4

TT menu doesn't work on my DS, or i did something wrong. I downloaded the menu and removed all other things from my card, put the TT menu on and the card didn't recognise it.
