I have a Wii with system menu 4.0 with cIOS rev10 and the Ultimate loader 7.4 with USB loader 1.5. Every game I've tried so far works great (except the ones with known issues of course) even Rock band 2 and the ACDC Track pack work fine. The problem i am having is with Guitar Hero 3 and Guitar Hero World Tour. Everything seems to work fine at first but randomly when playing a song it may either slow down for a second and the sound loops with it. causing the music and notes to become out of sync. sometimes the sound just loops and becomes out of sync with the notes by a few seconds. This doesn't seem to happen every time either sometimes songs play just fine. THIS is the Enclosure I'm using and I'm using a WD 160 GB hard drive.
