Today, my Wii started giving me the error "The system files are corrupted" after I hit A on the health and safety screen. I can't even get to the home menu. I haven't done any modding to my wii. I've tried resetting the Wii several times, but it keeps giving me the same error. I tried removing the sd card, the game disc, and all the gamecube accessories, but it still didn't work. I could mail it in to Nintendo, but that will cost a lot of money. Is there any kind of DIY fix for this problem? Even a fix that would require modding would be fine by me. I just don't want to have to pay a whole lot of money to fix my Wii.
