I just checked and my Wii is 4.0U and I use NeoGamma R7 channel to launch my back-ups. I also have IOS 249 rev14. I just bought Super Mario Galaxy 2 but it will not run. What all do I need to do to update my wii to play burned discs? Also I've always wanted to move over to using the USB Loader to save dvds, what is the latest for usb as far as channels and cios go? I read through the sticky but it seems to be more of a encyclopedia of Wii homebrew, a lot of it seems old and doesn't really suggest what is the best and newest to use. Thanks.
