A:AnswerIf you are playing the switch on your TV or even handheld, you can hook it uo and play via the controller instead of the one that comes with it or taking the joycons off
A:AnswerNo wireless adapter needed on our switch (not sure it is different for the different versions, we got our switch like 2 years ago) but that is why I went with this controller and yes they play with this one and two joy cons all the time! It connected pretty easy as well!
