I can't get my SSBB USA DVD9 to work and someone said that the wiikey 1.9g has problems reading dual layer disks. I think I have a wiikey 1.9g because i can play Mario Galaxy and the wii chipset is probably D2B (probability of 80%). Maybe the game will run if I update the modchip to 1.9s. But what if I have a clone wiikey or any other modchip? Can I damage the wii or the modchip in any way? If you experienced guys say that there is no risk of ruining my system, I may try to update the modchip... Please help me. My Wii doesn't even try to read the backup SSBB disk and the disk channel shows that famous question mark. I am sorry to bother you, but please help me! I am sure someone else may have the same concern but I can't find the answer on the internet.
