I’ve been working with PiPlay for a few months, and Shea had created a really nice controller GUI. you basically have to pick what emulator, and it shows a vector image of the correct controller and hit Button A when it states. It really worked well.
If we wanted to add a new controller after configuring it , can we just copy the button assignments from retroarch.cfg to a file in ‘/opt/retropie/emulators/RetroArch/configs’ and use the name that appears during bootup?
(or maybe a better way would be /retroarch-joyconfig -j 1 >> /opt/retropie/emulators/RetroArch/configs/filename-for-controller.cfg)
