How to play Gamecube games off softmodded wii
May 29th, 2014
Install MIOS and Gamecube Backup Launcher 0.2, attempt to load a burnt gamecube game into the Wii drive.
If unsuccessful you will need Wode or a older Wii drive replacement.
USB mode is disabled in Gamecube mode, that is why no one made a USB backup launcher for it.
It is said that with Wii NAND emulation you can attempt booting without a disk.
That is all I have to say, the rest is up to you to discover.
