Could I pair my PS4 controller with the Nintendo Switch and play with Minecrafg, for example? You can play Minecraft in splitscreen, if you have two controllers. Can you then play with the joy kons and PS4 controller splitscreen minecraft?
There's a third-party adapter that makes it possible to use the PS4 controller on the switch. Whether there's one for the PS4, which makes the Joycons compatible, unfortunately I do not know.
