I've installed batocera after a long and painful setup with Retropie. I was surprised that -almost- everything worked out of the box, without issues, big kudos for that.
One thing however doesn't seem to work. I could pair and setup my Xbox One controller via bluetooth instantly and it works very well, in menus and in games also, however my hotkey doesn't seem to work. At the configuring stage it's recognized my XBox button as hotkey, all seemed fine, but it seems that it doesn't work in NES games. No rewind function, can't reset the game, can't quit to menu, it doesn't save states, it's like I don't press the hotkey at all.
How could I get it to work?
