Wiiflow works on my 4.3J Wii -- it reads and loads most (but not all) back ups just fine from my 1TB USB HDD. USB Loader GX seems to recognize that the HDD is there, but lists 0 back ups. I have them all in a folder called wbfs, all lower case. I have tried WBFS in upper case as well with no luck. Also I have SNES GX and VBA GX installed. Both read fine from a USB stick but refuse to recognize any of several USB HDDs I have. Any suggestions? I can live without SNES and VBA, but I'd like to get USB Loader GX working to try the couple of back ups that aren't loading properly from Wiiflow.
