Have you ever thought about hooking up another console's controller to your Switch but you don't fancy either carrying around a USB adapter dongle or running an app on another device for hid-mitm? Look no further then, as sys-con is here to save the day!

Sys-con is a custom Switch sysmodule that allows you to use third-party controllers on your Nintendo Switch. Unlike the other previously mentioned homebrew solution, which, as the name suggests, worked by MITMing Horizon OS' built-in hid module, sys-con just needs you to connect your controllers using your Dock's USB ports: no Wi-Fi connection or external applications required. Not only this will result in less input latency (and, of course, a much simpler setup) but it also means the sysmodule won't conflict with Atmosphère 0.9.4's libnx input workaround, making it fully compatible with the CFW's latest version!

There are, however, a few limitations. First off, as hinted before, sys-con only works in Docked mode. The sysmodule is also only compatible with DualShock 3, Xbox 360 (wired, the wireless dongle reportedly doesn't work) and Xbox One controllers, with DualShock 4 support coming soon. Lastly, rumble and motion controls do not work at the moment.

Sys-con has been developed by @cathery and can be downloaded by clicking the download link below. It officially supports Atmosphère and will work on FW 5.0.0 and up (warning: crashes or freezes may happen on 9.0.X due to high memory usage). You can install it by extracting the release's contents on your microSD card, overwriting if necessary, and then rebooting your console. For more information on upcoming features, troubleshooting and developer support, head over to the project's GitHub repo (also linked below).

My 8bitdo wireless adapter stoped working... not complaining cuz I can now use 2 DS4 with my switch and with no input lag

 

[Ranshiro]

I had the same problem with the 8bitdo wireless adaptor but I was able to get it working by updating the adaptor's own firmware.

Is it possible to bind one key to multiple buttons or the other way around? For example binding the Switch A button to both LB and RB buttons on a xbox360 controller or bind A & B buttons to RT.

Also is it possible to make keybinds without the keys swapping around? Currently if I do this: key_DPAD_DOWN = FACE_DOWN, B button will swap with the down button on dpad. If I add another line after that where I try to bind the B key somewhere else: key_FACE_DOWN = RIGHT_TRIGGER, dpad will reset back to normal, B button turns into right trigger and right trigger unbinds itself.

I'm trying to make a button layout for xbox360 arcade stick for playing Groove Coaster. Currently the way the keys swap when changing binds makes configuring pretty difficult.

I just hooked up an extra dock to my arcade machine i have been working on, foolishly thinking that the usb zero delay encoders would be plug and play with this using a dualshock ini, turns out i didn't do my research and dualshock 2 isnt supported. Is there nothing that could be done about this currently?

I appreciate the hard work that goes into making stuff like this and i look forward to where you take it next.

I've read many topics and still can't find a definitive answer: Does this work with SX OS 2.9.3? If so, how do I do it?
I already copied the content to the root of my SD, but it still does not recognize my PS4 controller (it's the first model).

EDIT:
Finally made it work. But I have another issue.
The position of the buttons is swapped. The B button is not actually X as I thought it would be (to keep the original position). What would be the B button of the switch is actually O in the PS4 controller. I tried to remap them, so I add the following lines in the config_dualshock4 file of the config folder:

key_FACE_LEFT = FACE_LEFT
key_FACE_RIGHT = FACE_RIGHT
key_FACE_UP = FACE_UP
key_FACE_DOWN = FACE_DOWN

But it makes no difference when I tried. Do I have to do something else?

When I plug in my Xbox One controller, all I can use is the thumbsticks. D-pad, ABXY, triggers, bumpers, and Start/Select are all unresponsive. How do I fix this?

 

[Qubarf]

There is a known issue on all versions of sys-con regarding Xbox One controllers. if you update your Xbox One controller to the latest firmware, it stops working properly. Since you can't downgrade the firmware, I suggest you don't update your Xbox One controllers until a fix has been found.

Maybe this has something to do with it?

It was freshly purchased so I suppose that may be why. That's unfortunate, but oh well.

 

[mathew77]

Well, such a nice project!..

Btw, can you think about adding support to the PS1 Classic USB-controller?..

My dream would be to be able to play N64 games on RA using an original controller or a Hori Mini. Raphnet makes a fabulous N64 to USB adapter. Do you think one day it may be possible to use that with sys-con?

Is there any chance that wii-u controller will be supported? I really love that controller :3

 

[ElonStark]

I tried my wireless xbox360 controller and it works flawlessly with the xbox360 windows adapter plugged into the switch's usb port. That was a pleasant surprise!

 

[TR_mahmutpek]

I wonder if we can use multiple controllers at the same time. Like ds3 and ds4 plugged to dock and works like that?

I just use a Mayflash adapter. It cost less than $20 and works on my PC too.

I tried it with both my DS4 and my Xbox360 wireless and it kind of sort of worked. It took me a few tries to get the 2nd controller working though, and then it mysteriously stopped working after a few minutes. Eventually my switch crashed when the DS4 came unplugged in the middle of a Mario Kart race.

Strange, looks like we need some fixes. Thx for answer.

I think this dude has what you're asking for, and uses a 3rd party dock, to add cherries on top.



I think by doing this (below) you can connect 4 wireless X360 controllers.

Spoiler: comedy

But, um...just wondering, guys, has anyone had major issues on 9.1 with sys-con?

 

[Nikoru]

So I tried syscon and it works like a charm on my DS4 but I'm kinda disappointed though because the main reason I want to use this homebrew is to play Xenoblade 2 and Torna The Golden Country without that pesky JoyCon drift and it crashes whenever I play these two even though it works perfectly on Mario Kart 8, Mario Tennis Aces, Odyssey and even on a demanding ttle Astral Chain so yeah I dont get why it crashes on Xenoblade but works perfectly fine on Astral Chain. btw, it also crashes resident evil 4

 

[Crimson Cuttlefish]

Just checking in to see if Xbox One controllers work yet

 

[fst312]

Just curious, would it be possible to make one of those pc n64 controllers work with this. Just wondering because it would make n64 on retroarch better.
