Hey there, might be able to do one for you... question is do you prefer 3” trackball or 2 1/4”
Also with spinner, trackball, and action buttons the panel will have 3 USB connections. Mouse devices should be fine but a joystick/button encoder will come up as player 3 I assume if plugging in to your existing 2player bartop. With that in mind I assume all can be mapped without issue in Mame trackball/spinner games. I have plenty of pics of all my builds for reference, Private message me
