I did other test, the problem isn’t batocera, with my old arcade board it work fine, but i need to change it.
I tried to connect one of time the 2 usb cable setting and they work fine, but when I connect both, it’s a mess! One of the two player flip the joystick control and mess the 6 buttons function, not ever the same player. I tried to flip the joystick settings directly in the retroarch throw start+hotkey, in this way the game work find but then i have the wrong controls in the batocera them.
Please help me!
