OK, so in trying to get a game working, I changed the IOS # from 249 to 223 (I think) in the "Load Game" option screen of USB Loader GX. When I rebooted and started USB Loader GX again, I got a message, "No NTFS/FAT or WBFS partition found". I have since wiped the Wii's system memory and re soft-modded it. No dice.

Does anyone have any suggestions?

Many many thanks in advance.
