I been looking around for the last hour or so trying out a few things before i posted this help. Just before this 4.0.2 update all my Wii backups worked on my Wii U they show up in the loader but all games just go black screen then back to the Vwii menu. I have re-installed the CIOS i have tried cleaning out the files on the SD card and even tried my old housing for my hard drive. I am running Wii Flow 4.2 with a FAT32 hard drive with just Wii backups on it.
