WiitarThing

WiitarThing is a free Windows application that lets compatible Wii Guitar Hero instruments be used as controllers on a PC. The instrument connects to a Wii Remote’s extension port, the Wii Remote pairs over Bluetooth, and WiitarThing publishes the result to Windows as a virtual game controller that ordinary PC games can read.

Almost everyone uses it for PC rhythm games. Instead of playing on a keyboard or buying a new controller, you keep using the plastic guitar, drum kit or turntable you already own from the Wii era. It is also used for testing instrument inputs and for mapping Wii instruments to any Windows software that accepts a game controller.

Yes. WiitarThing is a free, open-source community project, and there is no paid version. Because it is distributed as a downloadable build rather than through an app store, take the extra minute to confirm you are downloading from the project’s own release page rather than a re-upload site.

This is the most common use case. Clone Hero reads standard game controllers, so once WiitarThing has created the virtual controller, Clone Hero sees your Wii guitar like any other controller. You still assign frets, strum and star power inside the game and run its calibration for accurate timing.

WiitarThing is built for Windows and that is the only platform it officially targets. There is no supported macOS or Linux build. Which Windows versions run cleanly depends partly on the driver or virtual controller component your specific WiitarThing release depends on, so check its notes.

Yes, for the standard wireless workflow. The Wii Remote is a Bluetooth device, so your PC needs built-in Bluetooth or a USB Bluetooth adapter. Adapter quality matters more than people expect — a cheap or unstable adapter is a frequent cause of dropped connections and pairing failures.

For the wireless setup, yes. The instrument has no radio of its own; it plugs into the Wii Remote’s extension port and the Wii Remote does the talking. If you would rather skip the Wii Remote entirely, a wired USB adapter is the alternative route, and it usually does not need WiitarThing.

Sometimes. Third-party and clone Wii Remotes vary a lot in how faithfully they implement Bluetooth and the extension protocol, and some never pair reliably or report extension data incorrectly. If you have the choice, an original Nintendo Wii Remote gives you the fewest unknowns to debug.

The Wii Guitar Hero guitars that connect through the Wii Remote extension port are the main target — the World Tour through Warriors of Rock generation of controllers. Exact recognition still depends on the WiitarThing version you run, so check the release notes for the build you download.

Wii Guitar Hero drum kits that connect through the Wii Remote extension port are documented as supported devices in WiitarThing builds that list them. Support is not identical across every version and fork, and pad or pedal mapping may need adjusting in the game rather than in WiitarThing.

The Wii DJ Hero turntable is listed among the supported devices in WiitarThing releases that include it, since it also connects through the Wii Remote extension port. Expect to map the platter, crossfader and buttons manually in whichever software you are using it with.

Generally no, and it is worth understanding why. Wii Rock Band instruments typically use their own USB dongle rather than the Wii Remote extension port, so they never enter the chain WiitarThing works with. Those instruments usually connect to a PC through their own receiver instead.

Yes. Each instrument needs its own Wii Remote, and each paired Wii Remote becomes its own virtual controller. Pair and confirm them one at a time so you can tell which player is which. Your practical limit is your Bluetooth adapter’s ability to hold several stable connections.

Open the calibration area in WiitarThing, select the connected instrument, then push the whammy through its full travel and release it so both ends of the range are recorded. Save, then confirm the axis moves the right way in your game. Re-run it if you ever swap instruments.

Hold the guitar in your normal playing position to set the resting point, then tilt it up the way you would in a song to set the activation point. If your instrument reports tilt through the accelerometer, it will be more sensitive to movement — binding star power to a button is the reliable fallback.

Delete any old pairing for it in Windows Bluetooth settings first, since stale entries block new connections. Then press the red sync button under the battery cover — or 1 and 2 together — and pair while the lights are still flashing. Fresh batteries and a different Bluetooth adapter are the next things to try.

Almost always the extension connection. Unplug the instrument from the Wii Remote, seat the connector firmly, then reconnect the Wii Remote so the extension is detected on connect rather than mid-session. If the Wii Remote itself connects but no instrument appears, check that your WiitarThing version lists that device.

A wireless chain adds a small amount of latency compared with a direct wired connection, but it is consistent rather than random, which means in-game calibration handles it. Run your game’s audio and video calibration, keep the Wii Remote in line of sight, and avoid a congested Bluetooth adapter.

Only if your specific release says so. Older WiitarThing builds relied on SCP-era virtual bus components, and instructions written for those builds still circulate. Newer maintained versions do not use them. Installing the wrong driver for your build is a common cause of a controller that never appears.

Newer maintained WiitarThing builds generally use ViGEmBus as the virtual controller backend, replacing the older SCP-era approach. If your release depends on it, install the version its documentation specifies and reboot if asked, then start WiitarThing again before pairing anything.

Yes, and for some people it is the simpler path. A USB adapter presents the instrument to Windows directly, with no Wii Remote, no Bluetooth pairing and typically no WiitarThing at all. The trade-off is a cable and the cost of the adapter itself.

For anyone who already owns Wii instruments, yes. Wireless play with original hardware still appeals, the PC rhythm-game scene is active, and community-maintained builds have kept the software working with current virtual controller components rather than leaving it stuck in the past.

Use the project’s own release page rather than a mirror, a file locker or a video description link. You are installing software that adds a virtual controller device to Windows, so the source matters. Read the release notes before running anything, and check which driver that build expects.

Close WiitarThing, download the newer release, and replace the old files with the new ones. Read the changelog before you do: if the driver dependency changed between versions, you may also need to install or remove a virtual controller component before the new build will detect anything.
