Just go the 8BitDo Ultimate 2.4G Controller and was surprised that it don't seem to work properly in Sequoia 15.1. Not recognized at al in some games and in some games only some buttons work. Seems fine on Apple TV and in iOS though, but there were some strange mappings in the game Dead Cells+ (Apple Arcade) when I tried that. A bit strange to see these problems if there's supposed to be "official" support from Apple on these controllers. Hmm....
In contact with 8bitdo support about it now.
