Most everything I've read regarding USB loaders is that IOS 249 is what should be used. However, Cfg USB Loader uses 222 by default (on my Wii at least). Anyway, I've been trying out WiiFlow and USB Loader GX (now my new favorite ) and they both were set to use 249 by default, but I would just get a black screen when trying to load any games. Switching to 222 fixed it on both of them. I installed 249 via the installer from ModMii, so I know it's there and all. Just curious about why this is really. Thanks!
