Have a Wii 4.2u, followed xzxero's guide, worked perfectly... Was playing burnt games, everything was working well, there was an update downloaded, not sure what update it was. The SD Card wasn't in the Wii when the update was done, after the update, trying to launch neogamma r7 would result in a black screen, everytime. because i'ma noob i figured i'll restart from the trucha bug, and hope that it fixes the problem, so i do that, reinstall neogamma r7, load it, this time neogamma loads, but when i tell it to load a game, i get the 001 this is an unauthorized disc error. As a final attempt i WAS going to restore the nand and start from scratch again, but i don't have a GC controller. If anyone knows of a fix for this plz help. Detailed steps would be best seeing as i'm quite noobish and don't want to brick my buddy's box.
