Get the wireless version. Not the bluetooth version. Reason is because the 8bitdo ultimate 2 wireless got a firmware update so it supports dinput mode when you power it on while holding down the B button. That provides full Steam Input support to rebind the extra 2 bumpers and paddles to any input you want. Wireless version does have bluetooth support, but difference is just that the one with the bluetooth name is one that connects to the Switch console over bluetooth and the wireless one made more with PC support in mind. Which is the reason it got dinput update while the bluetooth version didn’t.
