One of my friends lastnight downloaded some rockband 2 dlc to the wii internal through cfg usbloader. Anyways, to make a long story short. I deleted them off the wii turned the wii off and went to bed. Turned it on today and it said system memory corrupted. I reset with priloader, and select system menu from the options and the starts fine. Try to start wii normal and it still says system menu is no good. Thanks in advance.
