I bought this USB Game Controller from my local GameStop just to try for $17 and it is working in my Model 3 with new 48.12 update. Here is the amazon link for the same.
It is not a good brand I think but still works, so I think most of the gamepads should workhttps://www.amazon.com/Nintendo-Switch-Faceoff-Super-Mario-Controller/dp/B073X47SG9/ref=sr_1_7?ie=UTF8&qid=1545421048&sr=8-7&keywords=nintendo+switch+faceoff
It is so much fun playing with the gamepad, love it. Keep the games coming.
Damn you Nintendo.. you should have licensed Mario to Tesla.
