I recently installed d2x CIOSs (247 and 248) so I could get Metroid Prime Trilogy to work. I got it to work in Configurable USB Loader but not in USB Loader GX and I prefer to use the latter. Any ideas why it won't work in USB Loader GX? I have the newest version and tried on 3 different CIOSs with that block setting on. On another note, regarding Config USB Loader, how can I make it use CIOS 248 by default? Thanks
