Hey there!
I'm a noob to this and just recently got into emulation, never knew existed til I stumbled across the Raspberry Pi. Now I'm hooked and want to get more into it.
So long story short, I have Mame installed into Retropie 3.0 and I got all roms running and everything working great. I found out about FBA and loaded SFiii3 into FBA libretro (lrFBA in my case) and it works great with zero lag at all. My issue is I can't get player 2 controls on my cab to work ( player 1 is fine) . I have already switched the options in the meta data for 2 players. Just a thought but do you guys think because I have separate usb keyboard controllers for each joystick/buttons ( not using the IPAC controller ), FBA will not recognize the 2nd player controls? Any help is greatly appreciated.
