I am currently running Dragons lair on a pi3 3.6 retropie. Thank you for all the helpful tips here. I am still having issues with my 8bitdo nes pro 30 controllers withe the daphne emulator. The controller work great with the keyboard and the controller works once I add coins and press player one start. Unfortunately, I can not get these buttons to map. I have add the buttons from the jstest I ran (and +1 to each number as daphne states). I also added the auto mapping but no luck. Any suggestions to map the coin and start buttons?
Oh and during the menu videos the controller only pauses the game. It doesn’t matter what button.
