When I load a retail Wii game, I'm trying to use the normal disc channel on the top left of the first page. The disc spins in he slot, and I see a picture of a wii disc and a GameCube disc spinning. After about 10 seconds, the wii tells me that the disc is unreadable. It's not loading a game from the sd card. I use USB Loader GX 3.0 to load Wii Isos from an external drive and GC isos from a SD card. Should I still delete SD:/games/boot.bin?
