So – a few years back I bought two ‘X-Arcade Build Your Own Arcade Control Panel Kit’ they each support two joysticks, so I figured If I bought 2, I could finally build a 4 player beat-em-up emulator. I have retro-pi running, and we programed one Control Panel to use half the keyboard and the other control board to use the default controls. Mapped everything to the MAME emulator and this weird thing happens where the controller that is plugged in second, just mimics the controls of the first controller, so in the game instead of being able to control 4 guys, you’ve got two sets of controls two control one guy.

Will the tankstick driver help? Any other ideas?

Thanks for any help.
