Sorry if this was already commented, but I couldn't find it via search.
I've cleared the controllers folder, updated nintendont to the latest and got the latest meta.xml, and boot the non-autoboot forwarder in my WiiU VC because all my games are on SD card. I can go around and select different options. Games loaded just fine in the past via vWii homebrew channel, and gamecube adapter.
When I select a game though, it instantly locks up. It's reading from SD:\games. I've tried both shrunk and 1:1 ISO rips, both get the same response. I disabled the read speed hack. Only have memcard hack and WiiU Widescreen on, with cheats (since most of my games have a hack to make widescreen happen nicely)
Any ideas?
