I'm not getting input from the U-Trak and need help troubleshooting.
I've included a photo of the U-Trak connected the MiniPAC harness -- see attached photos.
When I try to configure the U Trak in a MAME game (by pressing TAB) the input is never registered.
I am using Raspberry Pi 3, with RetroPie, EmulationStation and using MAME4ALL as primary emulator.
All of my other buttons and joysticks are working great.
Any ideas for troubleshooting?
