I used PimpMyWii to update the io files. I followed the advice of someone else on another forum who also has a wiikey and was also at 3.2U, basically I did the auto update on all of the io files and menu update and ended up with (according to wii sys info page) 4.1x (x=a letter that I cant remember at the moment). After the update everything was working fine, it is just that NSMB backup will still not play. Any ideas? I have an early model wii and I figure I better do some sort of full backup. From what I understand, it is called a Nand backup. What is the best way to go about this?
