Download and install the latest release on the releases page

or install with cargo (binary name is switcheroo)
cargo install switcheroo-nx

The binary name is switcheroo

To display application use switcheroo help
Use switcheroo <subcommand> help for help with that subcommand.

Execute a payload.
switcheroo execute <path>

Check if the switch is connected.
switcheroo device

Start the GUI.
switcheroo gui

On many linux systems the usb control is blocked by default.

This can be fixed by adding the following file:
/etc/udev/rules.d/99-switch.rules
with the following content:

SUBSYSTEM=="usb", ATTRS{idVendor}=="057e", ATTRS{idProduct}=="3000", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="0955", ATTRS{idProduct}=="7321", MODE="0666"

then reload the udev rules:
sudo udevadm control --reload-rules

Finally unplug and plug back in the switch.

Due to a limitation of flatpak not allowing access to udev, the flatpak version only works if the Switch is already in rcm mode and plugged in when it is launched. If the application is launched without these conditions being met, it will never show RCM OK

On windows the rcm connection will only work if the Switch is using the libusbK drivers.
The easiest way to install them is to plug in the switch in RCM mode and use zadig to install the correct driver
