I just want to apologize in advance because I've been away from the scene from a while and don't really remember everything. On top of that, it's my sister's Wii so I don't really know what she did to it... Anyways, my sister's Wii I believe is 4.2U, the only things I put on there were the HBC, USB-Loader, and the channel forwarder. Never had any problems with any games or something. I think it was IOS 223 (Not positive). She then said when she started it up, it says her Wii's memory is full and won't let her do anything. I had this problem once because I installed too many WADs at once and filled up the system's memory, but she doesn't touch anything on the Wii besides the USB-Loader channel. I'm pretty sure the reason for this is because she tried downloading a Just Dance song (Through the game's menu, no WADs or anything). I really don't have any idea what to do to fix it since I can't access anything on the Wii. Also, deleting things from the system memory doesn't do anything. It just deletes the selected file and it still says it's full. Thanks a lot, guys.
