So I don't know if this is enough info, but my wii was on pre-loaded when I chose to return to system menu, but it gave an error, could not make out letter other than "h syst s rruptd. P as rr h Wii Opras ual for help roubshooting." I assume it means "The system files are corrupted. Please refer to the Wii Operations Manual for help troubleshooting." Correct me if I'm wrong. And this error only occurs when boot is via Priiloader.
