OK, cabinet build, Odroid XU4 and other hardware installed. Using the Lakka image with an Ultimarc iPac2 for joystick / buttons and a GGG TurboTwist Hi-Low spinner.
The spinner doesn’t work. I plug it into another PC, and it moves across the x-axis and clicks like it’s supposed to.
further research reveals I have to enable the mouse for the spinner to be available.
I see the option in MAME, but I don’t see anything for Retroarch / libreretro / Lakka on how to enable the mouse.
Very few pieces of documentation have been found, and so far none have been useful.
How do I get the system to use the mouse?
