Hi. I know many people have been having problems with Guitar Hero 6 Warriors of Rock for wii. Those who purchased the game legitimately and tried playing on their modded wii were getting an "Error: 002" upon loading the game. Go download USB Loader GX and install it. Once installed and loaded, load the disc in USB Loader GX. Go to settings and turn "002 fix" to yes. Run the game. Enjoy. Note: It's working fine on IOS249.
