I've been having an issue trying to get USB Loader GX to recognize my drive. I have a 1TB WD My Passport external with a 100gb wbfs partition that is set to a primary partition. When I plug my external to either back usb port on my wii u, my external shows a blinking light. However, no matter...
although i ended up accidentally changing my nand with no way of going back bc i didn't know you needed a gamecube controller to restore it (i have a wii minus/1.1, which doesn't have gamecube controller support)
and if i find the sd card i have my NAND backed up on, i can not only restore the NAND if i solder the right part in, but i can also put my NAND on dolphin, then i can play dolphin online, like PMEX Remix or MKWii Riibalanced
