Do any major Switch emulators natively support JoyCons the way Dolphin does WiiMotes? (Do JoyCons even use regular ol' Bluetooth the way the WiiMotes do? EDIT: quick Google says yes :) )
I have no experience with JoyCons unfortunately. I use an Xbox Elite controller + PS4 controllers. They map extremely well to a Switch Pro controller in Yuzu emulator. Launching Yuzu via Steam via Parsec works surprinsgly well to recognise the controllers, despite the occasional hiccup. Smash Bros and Mario Kart are a blast on the big screen.
I figure in Smash, Kart, etc; it doesn't matter, but I'm just curious how deeply the motion controls affect the gameplay on average in Switch games. :)
It currently sits in a box somewhere in my house because I have never had any use for it, which I think is the case for most PC gamers, hence its failure.
