First thank you for a great product, the interface and ease of configuration is really helpfull, coming from retroarch.
There's one problem i'm running in to though. I've been testing Batocera on my Pi 4 and had a great experience. But when installing on my pi 3 i run into the problem my wiimote with plugged in wii classic controller is not working in any of the cores. On the pi 4 this was working great out of the box, but on the pi 3 it's only working in Emulationstation.
I've tried configuring the controllers and assigning a specific controller to input p1, but i can't get it to work in the cores.
Has anybody got an idea where to look next?
