Third time again, but for some reason I am forced to install the Wii VC inject to RedNAND and guess what? It gave me error code 160-2793 when I launched it. Don't know if it's the inject, the SCT or the Wii U Installer Packer though.
I'd wait until dimok releases FAT32 support for mocha. Then we can install a regular Wii VC to USB and replace the nfs files on our PCs.
