I just installed a clean version of RetroPie 3 beta 2 (for the Pi2).

I copied across a rom into the fba rom folder and it played and it read the:
/opt/retropie/configs/fba/fba2x.cfg file

I confirmed this by changing this line
QUIT=119 (119 = w. It usually reads 27 which is ESC)
When I did this, ESC no longer quit fba, I had to press “w”.

If you know the key presses being produced with your jpac you can get the ascii equivalent for the config file here:

The reason I said to update your firmware is that users on this forum who have used the ipac have said that it resolved their input issues. However, as you say, if you are concerned this may damage your device, please dont do it.
