I ran into a problem when I was going to play backups off a flash drive using USB Loader GX after installing my games to my flash drive using Wii backup manager and then hiding the flash using Ustealth. It worked perfect when using a forwarder channel from the Wii U menu but after exiting from vWii back to Wii U and going thru the forwarder again it no longer did. I guess that’s not a real issue because simply going to it normally in vWii thru HBC makes it function again, but I’m mentioning it just in case it’s important. I had to make some changes to my flash so I put it back into my PC and used Ustealth to unhide it, it said it did make it unhidden but unplugging it and plugging it back in just prompted me to formate it again and it was still hidden in ustealth. Sorry it got lengthy but that’s what’s going on, I’d really appreciate if anyone could help me out. Cheers! My Wii U is on Tiramisu as well.
