Stupid Wii

Right about to get the last mask in Majoras mask, right before the moon crashes so I can get up into the clock tower, and beat Majora with the one mask you get if you get absolutely all of them, and my game freezes up, making me have to get 3 masks, the big wallet, and do the Kafei and Anju thing ALL OVER AGAIN!!! Sometimes the Wii just screws you over...
