I recently hacked my Wii, and I have Homebrew and USB Loader GX, and I can use USB Loader GX to load backups of Wii games, but for some reason I cannot open GameCube games. I have a Mac and I am using Witgui to transfer ISOs of games from my Mac to a WBFS formatted USB Drive, which I then put into my Wii. This process works for Wii games, but I used Witgui to transfer some GameCube games and they don't work. How can I play these GameCube games on my Wii?
