Bump, adding /opt/retropie/configs/all/retroarch.cfg file to the first post ... I don't see anything wrong with it. Yet neither controller or keyboard work with lr-cores.
EDIT : managed to get back controls on lr-cores by deleting /opt/retropie/configs/all/retroarch-joypads , disabling , enabling xboxdrv, remapping the controllers and lots of reboot
On another note, no progress on getting enhanced resolution and analog support with pcsx-rearmed :/
