My external USB drive doesn't seem to work with any of the popular backup loaders. (I used WBFS Manager, and followed all of the instructions.) When I use it with USB Loader GX, it shows the game, but when I launch it, it disconnects the Wii Remotes and freezes. Can I use a DVD-R or DVD+R with USB Loader GX? If so, which one? If not, what backup loader does support them?
