I am play with original hardware mostly, but I try from time to time things like aje pcbs, and others RPI solutions.
Recalbox like any other arcade related hardware is designed by people who let say don't have common (minus Darksoft who do really awesome but expensive plug and play solution)

Regarding your problem It either it assign your controller to a new a new input everytime you boot and other time the input file is on conflict with the original file and something make it read only. try a new install it may work better after that.

If you use a arcade stick, best solution for autofire is an dedicated +5v pcb you put inside (I have those on my Cocktail table) you can even build it yourself for less than 5 dollars. Good luck
