joinski Thank you for your reply, i'm using Batocera 5.25
Yes, it happens for every emulator off retroarch, i use 8bitdo n30 pro and Dualshock 4 on may laptop (PC)
May joypad recoginized in retroarch normally but as a 2nd controller, and default input of retroarch is my laptop keyboard, i tried change to may joypad in the F1 menu and it work but every times i'm out of F1 menu the setting of retroarch is reseted.
So my problem is how to change my joypad as the first input default or how to save setting of retroarch after quit F1 menu. I have used Batocera 5.24 before and retroarch work perfect because it recognized my joypad as first input
