I did all the steps I could find to get gamecube games working. I used dml 2.10 wad in a wad manager. When I use configurable USB loader only wii games show up. I don't know what I could need to do to get it working. I reformatted the sd card to 32k Fat32. I barely got it working for Wii games, it turned out I needed a META file. Perhaps I need a META file formatted for gamecube? Also, it's doing something where it don't remember my options. I change the theme and it changes back when I restart the configurable usb loader.
