Ok, so im messing with my new 1tb hardrive & usbloader GX. Played my backup of wii fit plus, hit go back to wii menu & poof... "your system files are corrupted" I'm on 4.1 with preloader installed, think ive got a back up but couldn't tell you where it is... So boot into preloader 0.29, try system menu. Works. Ok so reboot try as normal. Works. WTF??? Anyone else ever had this? Any idea if i need to be worried? Bueller?
