My friend's wii has always had this problem but trying to get all my gamecube games backed up and testing them, the freeze has proven to be annoying and mysterious. Basically, 1. Gamecube disc or gamecube backup disc inserted into wii 2. Wii goes to system menu 3. Wii freezes It doesn't freeze if the disc is inserted at any other moment. I can browse the HBC without the wii freezing and et cetera. Unless things have changed drastically, I think he has some form of cioscorp installed because I can see wii backups at the disc channel. Other than that, I think he used ModMii a few weeks ago. Has anyone heard of something like this happening and would know a way to solve this?
