I picked up a Magic NS adapter from a second-hand shop. The latest firmware update added Wii Remote + Classic Controller support. I have a Tatsunoko vs Capcom stick that is basically a giant claasic controller. I modded it with side buttons wired to ZL and ZR and use it as a pinball controller.
So now my Switch has a wireless arcade stick and a sweet pinball controller for both tabletop and docked mode. There is no perceptible lag but if I want to get picky I do have a HRAP4 for PS4 that the Magic NS will work with.
It's like having a portable modular arcade machine.
(Note: the adapter isn't actually in use for the pics because i'm waiting on a USB A to USB C adapter arriving on Wednesday. It was supposed to come with one but it didn't so I had to order one for $5. But this will be the set up away from the TV)
