Sys-con is a Nintendo Switch module that adds support for all HID and XID joysticks and gamepads to the Nintendo Switch.

Only USB connection is supported. If you want to connect your controllers using Bluetooth, you should use ndeadly's MissionControl.

Some of the supported controllers include:

All PC Controllers
All Playstation Controllers
All Xbox Controllers
Wheels

A complete list of tested controller is available here.

Features

HID joystick/gamepad/wheels supported (PC Controller compatible).
PS and XBOXs controllers supported.
Custom key mapping using VID/PID and profile.
Automatically add new controllers (Try to determine the best driver).
Configurable deadzone.
Configurable polling frequency.
Configurable controller color using #RGBA.

Installation

Grab the latest zip, extract it in your SD card and boot/reboot your switch.

Configuration

The sys-con configuration folder is located at /config/sys-con/. It includes settings for controller button mappings, stick configurations, trigger settings, and deadzones.

The configuration is loaded in the following way:

Global Settings - The [global] section is applied only once at boot. To update settings here, reboot the Switch.
Controller-Specific Settings - For each controller, configuration is applied in the following order:
- [default] - Loaded first.
- [VID-PID] - Loaded next, where VID and PID correspond to the controller’s vendor and product IDs.
- If [VID-PID] contains a [profile], it will load the [profile] then load [VID-PID].

In other words, the loading order is: [Default] [Profile] [VID-PID]. If you want to override a setting for only 1 controller, it's adviced to change the configuration in [VID-PID] in order to not impact others controllers

Logs

Logs are stored at /config/sys-con/log.log on your SD card. The logs are automatically created with a log level equal to Info.

For more verbose logs, modify /config/sys-con/config.ini:

[global]
log_level=0

Then reboot your Switch.

User guide

Configure a controller

When a new controller is connected, sys-con attempts to automatically assign the best profile. Most features like arrows and joysticks will work correctly, but button mappings may need adjustment. If you find that buttons are not correctly mapped or the right stick is reversed, you can manually configure the controller using one of the following methods:

Method 1: Configure on the Switch (Recommended)

Connect your controller:

Connect your controller to the Nintendo Switch.
Open the input test menu: On the Switch, go to: Settings > Controllers & Sensors > Test Input Devices.

Test each button:

Press every button on the controller and write down or memorize how the Switch reports each input.
Your goal here is to understand the correct mapping for your specific controller.

Edit your sys-con configuration:

On the SD card, open: /config/sys-con/config.ini
Locate the section corresponding to your controller’s VID-PID, which looks like: [vid-pid]
This section is usually added automatically when sys-con detects an unknown controller.
Most of the time, it will be at the bottom of the file.

Tips for Faster Iteration:

The config.ini file is reloaded every time you plug in a controller. To speed up testing:
- Install vgedit on your Switch.
- Unplug the controller.
- Edit config.ini directly from the Switch using vgedit.
- Re-plug the controller to reload the config.
- Test your changes immediately.

This allows very quick trial-and-error cycles.

Typical configuration will look like

[0810-0001]
B=1
A=2
Y=3
X=4
L=5
R=6
ZL=7
ZR=8
minus=9
plus=10
home=11
capture=12
rstick_left=-Rz
rstick_right=+Rz
rstick_up=+Z
rstick_down=-Z

Where ButtonName (A,B,Y,X...) should be assign to a ButtonID (1,2,3,4,5...) you determined from testing. For example, if you found that 'B' is reversed with 'A', just swap the ButtonID:

B=2
A=1

Method 2: Configure using a Windows PC

Note: Button mapping can differ between windows and the switch

Finding the VID and PID:

Plug your controller into your PC.
Go to Control Panel > Device Manager.
Locate your controller under Human Interface Devices, right-click, and select Properties.
Go to the Details tab and select Hardware IDs to find the PID and VID, which will look like HID\VID_0810&PID_0001, translating to [0810-0001].

View Button IDs:

Open joy.cpl (either from Win+R or directly from the Start menu).
Select your controller and click on Properties.
Here you should see a panel with ButtonID (1,2,3...), press the button and make a note of them (which button is assigned to which ID).

Update Configuration:

On your SD card, open /config/sys-con/config.ini.
Edit the [vid-pid] section with the button IDs you noted:

[0810-0001]

B=3
A=2
Y=4
X=1
L=7
R=8
ZL=5
ZR=6
minus=9
plus=10
home=11
capture=12
rstick_left=-Z
rstick_right=+Z
rstick_up=+Rz
rstick_down=-Rz

Replace ButtonID (1,2,3,4...) from your PC testing. If this method does not work or mappings are incorrect, use Method 1.

Button mapping

List of possible mappable switch buttons:

lstick_left=
lstick_right=
lstick_up=
lstick_down=
rstick_left=
rstick_right=
rstick_up=
rstick_down=
B=
A=
Y=
X=
L=
R=
ZL=
ZR=
minus=
plus=
lstick_click=
rstick_click=
dpad_up=
dpad_down=
dpad_left=
dpad_right=
capture=
home=
simulate_home=
simulate_capture=

List of possible values:

1 to 31 - Represent the Button ID of the controller.
Z, -Z, Rz, -Rz, Rx, -Rx, Ry, -Ry, Slider, -Slider, Dial, -Dial, Brake, -Brake, Accelerator, -Accelerator - Represents the analog inputs (e.g., joystick, slider).
32 to 35 - Represents the hat switch (D-Pad) directions
- 32 - dpad_up
- 33 - dpad_down
- 34 - dpad_left
- 35 - dpad_right

Deadzone

Additionally to these mappings, you can configure deadzone for every analog:

deadzone_x=20
deadzone_y=20
deadzone_z=20
deadzone_rz=20
deadzone_rx=5
deadzone_ry=5
deadzone_slider=20
deadzone_dial=20

factor_x=100
factor_y=100
factor_z=100
factor_rz=100
factor_rx=100
factor_ry=100
factor_slider=100
factor_dial=100

All these values are in percentages:

Typical deadzone range: 0% to 30%
Typical Factor range: 100% to 150%

Shortcuts

By default, the HOME and CAPTURE can be triggered by pressing Minus + DPAD_UP and Minus + DPAD_DOWN, respectively.

Minus button is often mapped to the select button.
