Did the old delete and reinstall, took some fiddling to get the launcher to work again but all works perfectly now, cheers.
Seriously, thanks to all that have worked on RetroArch for WiiU - this is awesome!
I'm running rpx 2018-08-16, all the cores are running fine, but the menu icons appear as just mumbled garbage (like an ascii picture) on my wii U (running 5.5.1) - any ideas how I could fix this? Thanks!
