Ok, so I haven't had any problems with my wii in the 6 months I've had it, but suddenly it's having issues. Now whenever I try to load the system menu I get the "system files are corrupted" message. Here's a list of all the relevent information about the state of my Wii: System Menu 4.2. I updated a couple weeks ago and everything was running fine, but suddenly today I go to play and get issues. Haven't done any modding since I last played when everything was working fine... Preloader .29 installed. It loads fine on powerup, but can't load system menu from there. HBC. Can load it successfully from preloader. Bootmii as IOS. I am able to load it from HBC, so I can theoretically do a NAND restore correct? NAND backup on SD card from immediately before 4.2 update. ... I'm still able to play games via backup loaders through HBC, so that's not soooo bad...but the sudden loss of the system menu is disturbing... Help?
