Second sdl gamepad not working for NES on RPi

[tregota]

Sorry if I'm too far off here.
I have two RetroUSB.com RetroPad NES controllers and run RetroArch on Raspberry Pi.
The first controller works fine but the second doesn't do anything.
It's configured correctly as far as I know and I've gone as far as to put some logging into the function that polls the controllers and it does poll the second controller and also recognize button presses. I'm not sure where to go from there though.
Any ideas?

You're using an old FCEUmm core. Try to build from Git. I believe there were some 2-player input issues which were fixed.

Ah thanks, that did the trick!
I'm using chameleonpi and it had the latest code from git but still had and referenced an old version.
