Freeplay CM3 Slim with shoulder button upgrades

[Hipcat]

Hipcat, can you try the new driver version : https://github.com/TheFlav/mk_arcade_joystick_rpi

You will have to add " auto_center_analog=1 " in mk_arcade_joystick.conf to check if it solve your problem.

Thanks a lot for all your info. I was pretty stuck on it, but Ed Flavor figured it all out and now everything is great. I really appreciate your help.
