I have retropie installed on a Raspberry pi2, and I want to create a retroconsole-arcade cabinet at same time. I have configured all systems with keyboard (I-pac2) and Joypad (Ps3 dualshock 3), all works correctly, but in lr-fba, the coin button (select), doesn’t work in the keyboard, but in the joypad works perfect
What I did was when I booted into lr-fba-next I opened up the RetroArch GUI while running the game, went to the binds and changed the coin button that I wanted from there then went into configuration then enabled save on exit. Quit the game, then rebooted to try and once I saw it working I turned the save config when exit off and quit again then tested and the button I wanted for coin was saved perfectly :)
I use a DualShock 4 and set my coin button to 12 which is the PS GUIDE button inbetween the sticks.
Are you sure thats the file I mentioned above (either way its not ideal wherever it came from). It should look more a bit more like this: http://pastebin.com/raw.php?i=5YN8wfE7
