I bought this beauty and am very impressed with it. Tempest, Centipede, Millipede and Missile Command work great with only 1 minor change in Retroarch.
I cannot however get the spinner to work in Stella / 2600 games. I've been testing with Breakout mostly.
I have been to the Stella Wiki and I see the input menu but nothing will bring that up in Batocera that I can figure out.
