oh cool! yeah so i hear its easier with Batocera
especially if your using two guns apparently its super complicated to get a second gun working otherwise. i saw an endless wall of AHK script for it
seriously contemplating going back to Batocera but ive got BigBox and its really good and i wunna make it work, i think 3/4 of my lightgun games are working perfectly so far.. even wii games work with a bunch of aim hacks. do you have PS2 games working? also does Batocera have its own boarders for sinden or something? its annoying af to setup overlays for a boarder in every emulator.
