I have an old I-PAC (I don’t even think it is an I-PAC2) that I got back in 2008. I’m trying to get it to work in Batocera and having a hard time. I followed this instructions here DIY Arcade Controls and got it to somewhat work. The Start/Select only work on player 2 and the buttons seem to work inconsistently.
Should I just bite the bullet and buy a new I-PAC2 ?
