#### Debian 12
```bash
sudo apt install pkg-config cargo libudev-dev libevdev-dev libevdev2 && curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
```
Compiling requires rustc >1.70.0, but Debian 12's apt repository goes up to 1.63. Hence the rust installer from https://www.rust-lang.org/tools/install is used instead.

From Debain 13 onward, you can use `apt install rustup` instead of the Rust install script.


### Hardware

This is tested with a Wii MotionPlus Wiimote, and a Guitar Hero World Tour guitar. It should work with the other Guitar Hero Wii guitars (which have a slot for a Wiimote), and other Wiimotes, as long as both are recognised by the Linux kernel, though they have not been tested.

Provided in the `etc` folder are an example udev rule and systemd service to automatically run Roadii when a supported Wii guitar controller is connected. This presumes you are using SteamOS, adapting to other Linux systems is left as an exercise for the reader.

### Steam Deck

1. Install `roadii` and `evsieve` executables to `/home/deck/bin`
2. Copy `etc/systemd/system/roadii@.service` to `/etc/systemd/system`, and `etc/udev/rules.d/99-roadii.rules` to `/etc/udev/rules.d`.
3. Reload the udev rules with `sudo udevadm control --reload`

Now you're ready to connect your Wii guitar via Bluetooth!

### Non-Steam deck

1. Install `roadii` and `evsieve` executables anywhere, as long as it's in PATH
2. Run the code below

```bash
# Use a path lookup to determine install locations
evsieve_path=$(type -a -P evsieve)
roadii_path=$(type -a -P roadii)

# Replace default Steam Deck locations with fetched locations
sed -i "s~/home/deck/bin/roadii~$roadii_path~g" etc/systemd/system/roadii@.service
sed -i "s~/home/deck/bin/evsieve~$evsieve_path~g" etc/systemd/system/roadii@.service

# Copy the service & udev rules to their target locations
sudo cp etc/systemd/system/roadii@.service /etc/systemd/system
sudo cp etc/udev/rules.d/99-roadii.rules /etc/udev/rules.d

# Reload the udev rules
sudo udevadm control --reload
```

Now you're ready to connect your Wii guitar via Bluetooth!

## Usage

With the udev rules and systemd service configured, the guitar will appear as several devices; ignore any which mention Nintendo, as `evsieve` has taken exclusive access to them - the one you care about now is simply called "Wiitar".
