Homebrew Question Control Switch with a PC

[Karathan]

I want to use my switch through a controller connected to the PC. This enables me to play coop with a friend that doesn't have a switch. Is it possible?

Two main paths to such a thing, I assume screen capture is handled by HDMI or whatever streaming option is available.

1) You hardwire it in the other end -- all those things people do for turbo buttons, external controller adapters and whatever else work just as well for taking input from something else. This will require you solder into the controller, or maybe make some kind of adapter ( https://gbatemp.net/threads/switch-fightstick-scripting-inputs-to-automate-games.496148/ ).
Personally I would buy a cheap third party device (not like you need the rumble or for it to feel good in your hand here) and solder it accordingly.
Modern PCs don't output nice clean signals very well (all the old methods they used to do that on are rarely seen any more) so you will probably want a programmable device like an arduino, teensy or if you want overkill I guess a raspberry pi could be made to do it too. You could possibly use a nice USB to serial adapter but for the money I would much rather have an arduino to do some extra stuff if you wanted it, though it looks like https://github.com/wwwwwwzx/NXController already supports usb-serial.
No hacked switch needed for this, and will drop into whatever switch you have to hand really.

2) You hack the Switch and use a network control mod (though you might have to chain a few things together* if you are going to be on an internet connection, nothing drastic though). I don't know what we have for this right now, if we have anything at all (it is not so commonly done, most people being more concerned with remapping buttons instead).

*most Switch programs are not going to house a full network security thing so you will have to remote control the PC or VPN into your friend's network. Likewise joypad connections are not always sent over the internet, but we have a thousand different programs to fake mouse or keyboard inputs for such a thing. All quite basic and easy, just extra steps depending upon what you want.

Thank you so much! I'll try the 2 option. I'll remap with xpadder and use parsec for streaming.
