So I just tested retropie via image in the last days and I love it. My controller didn’t work so I started the config and registered a RetroArch controller. Everything went fine.
Since I wanted everything to run on raspbian (pyload, xbmc, retropie, scripts, home automation, etc.) I installed it from source via git. Everything runs nice now but I can’t use the RetroArch controller registration. I don’t get an error message. It just doesn’t start, says config is written and thats it.
