I remember the original 3DO could daisy chain controllers together for multi-player games i.e. twisted.
When I go to retroarch settings for the 4do and go into setting>input and try to bind the keys for player 3 and 4 the inputs all say n/a instead input b, etc. I can still enter inputs in but it seems not to register in game.
I checked “controllers” in the retroarch settings and it seems to list only player 1 and 2. I have two fightsticks plugged in via usb and two wireless xbox controllers connected via wireless receiver, but not matter the configuration of the controllers I still only see 2 controllers available for binding.
Is there a way to add more controllers in the 4do core?
