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.

What I see from Retroarch is
1.10.3 - Stella (7.0_pre-ba51197)
When I use the spinner and trackball in retroarch, the mouse pointer moves. However I cannot get it to actually register in any of the input fields. I’m not sure where it goes, but I’ve been poking around some guesses with no luck.
