I just set up homebrew on a friends Wii. USB Loader GX works fine if I use my hd that is formatted as WBFS. Since she wanted to be able to use her HD for her PC too I used NTFS for hers and used Wii Backup Manager copy the games from my WBFS partition to the wbfs folder on her drive. When I use her drive, GX sees the games, but just gives a black screen when I try to load any of them. Again, using my drive instead, everything works normally. Her HD is a Hitachi XL500. Any ideas?
