Hi, I burnt SSBB to a dual-layered disk, which had been patched to PAL and had the modchip error removed. The game works fine, but then when I tried to go on adventure mode with 2 players, after a couple of minutes of playing Mario V Kirby, the game freezes and then a strange loud noise plays, and the only way to turn the Wii off is removing the power lead to the Wii. This also happened when I was in a Brawl with a friend and he used Mario. What could be the problem? Thanks, Jake.
