I have retroarch with launchbox. I cant get retroarch to recognize the 2nd controller, although it works when I try to map in settings in launchbox.
Issue seems to be with retroarch. But when I start a game, it says xinput is good but ps3 wireless is not configured. So I go to quick menu, as forums have suggested, but the section where controls are in is in really small Japanese characters, so I cant even configure it.
