After update, gamepad stops working [Freeplay Zero]

[Flavor]

I'm in the same boat. I was trying to see if I could get ppsspp to work by updating Retropie. I've tried 0.1.5.6, 0.1.5.7 and 0.1.5.10 and neither seem to work.

After updating to the latest (which I think is now 0.1.6.0), can you post the output of

Code:

cat /etc/modprobe.d/mk_arcade_joystick.conf

It really only needs a single line in there, but it may be rather large if you tried to update several times. I'm guessing that you have an old line in there that doesn't have the correct number of options for the gpio parameter (just a guess).
