Thread title basically outlines the problem. Issue: A recent onset problem using a 4.3U Wii with USBLoaderGX 1.8: I can not play any GC games ripped to a FAT32 16gb SD card. When I press "Start," the screen fades black and after a couple seconds, flickers and reboots back to BootMii. Wii games ripped to USB work fine and do not reset, as do VC and Wii Channels. USBLoader and the Wii can both start GC games by disk still. This all results after a previous disk installed Wii-Update from the CoD BO DVD, as before this disk install, the USBLoader started GC games just fine without issue, as well as ripped Wii games, VC, and channels. Attempted Fix: To fix this problem, I've tried reformatting both USB and SD drives, flashing the NAND back to a point where I just had Homebrew and BootMii installed and then reinstalling the mandatory IOSs for USBLoader, and putting the GC ROMs on a USB harddrive instead of SD. None of these attempts have fixed the problem; GC games still reset the Wii back to BootMii. I would appreciate some advice as to how to remedy this issue. My suspicion is that the CoD BO disk updated some files which conflict with what was needed to boot GC games off of SD via USBLoader, but if so, I do not understand why flashing the NAND back before the disk update was installed would not fix this issue. ps: I also apologize if I've skipped any mannerisms expected from a "help" post like this. If it's too much of a bother, I have no objections to this thread getting locked.
