I'm working on just a goofy little project to intercept SNES button pushes to my Raspberry Pi 3. I read some schematics of the controller and decided to dismantle an SNES to solder wires to the back of the controller port for the clock/latch/data signals.
Here's a picture of what that looks like: http://i.imgur.com/vhgaGOd.jpg

I can't seem to install the right drivers to intercept the button sequences, though. The error message in the log (posted above) doesn't provide me with much help.

Oddly enough, I can manually set up a listener with modprobe gamecon_gpio_rpi map=0,0,1,0,0,0 and am using jstest /dev/input/js0 to intercept signals. Things appear to be working, with a slight twist: every time I hit the B button, every single button is pressed. Here's a GIF of that sequence: http://i.imgur.com/jghmFmh.gif

My ultimate goal is to be able to intercept the button presses on my SNES controller. How can I move forward on doing that? Happy to provide any additional information necessary!

@gjtorikian from a terminal what is the output of uname -a ?

[gjtorikian]

It's:

Linux raspberry pi 4.1.19-v7+ #858 SMP Tue Mar 15 15:56:00 GMT 2016 armv7l GNU/Linux

You need to update your Raspbian packages. Looks like you have updated retropie but not the system.

@BuZz That did it, thank you! Out of curiosity, how were you able to identify that as the problem?

@gjtorikian your kernel was old.
