@zing I'll have a look and see if that's the issue.
Right now I am able to load games with my P2 Joystick being selected as P1 in the configuration menu, and my P1 Joystick as P2. But when I load games with two players it comes up a yellow text at the bottom of the screen saying that GPIO controller 1 is not configured, so I'm guessing that has to be the issue.
@xanarkan oui il s'agit d'une feature arm/neon only.
L'ajout de nouveaux cores, dont le mednafen psx est prévu. Mais nous avons d'autres chantiers "techniques" à terminer avant de nous lancer la dedans.
