WiimoteHook: Nintendo Wii Remote driver with MotionPlus, Rumble and Nunchuk support

What this is:

WiimoteHook is software for the Nintendo Wii Remote that has native support for MotionPlus-based motion, the Nunchuk, Rumble, Mouse emulation from Gyroscope data, and XInput output. It can be used in a standalone fashion as an XInput, DS4 or mouse emulation layer but when combined with Cemuhook’s motion API it provides 6-axes based motion on Cemu games from gyroscope and accelerometer data to the emulated GamePad or emulated Wii Remote.

When driving a vanilla Wii Remote without MotionPlus hardware, the software retains basic 3-axes motion via Accelerometer data, which can be useful on games that use it as a “Wii Wheel”, like Mario Kart 8.

Various additional options are provided by the software like multiple and custom orientations, DS4 hardware emulation, Rumble custom settings, multiple(unlimited) Wiimotes, and more.

How to use it / Requirements:

Step 1: Get the latest WiimoteHook zip from the end of this post and extract the full folder to a location including its subfolders. To extract the folder if you don’t have a third-party tool for the job, just right click the .zip and select “Extract All..” or copy & paste the folder to another location after you open the .zip with explorer.

Step 2: Install the emulated gamepads driver included in the WiimoteHook folder by running InstallEmulatedGamepadsDriver(run as admin).bat (right click->run as admin). This is not strictly required but it allows WiimoteHook to produce the Rumble effect and a convenient XInput device for Cemu’s Input menu. The feature called “Also use for buttons/axes” of Cemuhook is also supported alternatively. Win 7 machines also need for the XInput feature(ignore these URLs for Win8, 8.1 or 10): the xbox360 driver, and this security update. An alternative method is to install that driver from here.

Step 3: Run WiimoteHook.exe to automatically pair with or connect to a Wiimote, deal with its incoming data and launch the motion server and xinput output. Let it run in the background. In case it is required, a .NET 4.5.2 installation link is included in the zip. When WiimoteHook first runs, and provided the controller is properly paired and connected to windows, the Wiimote should be detected by the application (next pic).

Note: When WiimoteHook first runs and if it doesn’t detect a device it will offer to automatically pair Wiimotes with Windows by pressing “B” and then pressing the red button on the Wiimotes (next pic); this needs standard Bluetooth support (if you’re in the market for an adapter, special ones aren’t required; a generic CSR 4.0 works well); If the pairing process fails (possibly because of an unsupported bluetooth stack) you can manually pair the device with standard windows tools. In order to manually pair the device on Windows 10 and avoid the PIN question you might need to “Add” it as a device in “Devices and Printers” and click Next when asked for a Pin, without entering a pin. While Windows 7 or older installations can pair with the new Remote Plus devices, they require the Toshiba bluetooth stack to properly communicate with them.

Note: DolphinBar also works if set to mode 4 and since it always exposes 4 devices, it’s normal for the software to detect bogus ones at launch before a real one is detected. If a DolphinBar doesn’t work at first, it’s reported reconnecting it to another USB port helps.

Note: To reconnect a paired remote after it’s disconnected press “A” so that it’s detected by the PC and it’s reported “connected” in Windows. This is normal behavior for various gaming controllers. They power off to save power after disconnections and they need to wake up by a user action.

Step 4: Optionally, configure the application with the settings editor (or leave it at the defaults for a start). Various niche options not described in this thread are in the .config file; the config editor can open with “S” from the console.

The software also features a tray icon which can be used to open the configuration, toggle the visibility of the console and exit the application (double-clicking it also toggles the visibility of the console).

Step 5: Test motion with PadTest found here (next pic). To do that use the Port set for WiimoteHook (26760 by default), click “Start”, then double-click a detected controller . To test Rumble and XInput support run XInputTest found here. If you had used another motion server in the past that had a custom remote IP in cemuhook’s ini you will need to either edit that setting or remove it.

Note 1: The Orientation for motion can be changed by pressing “O”/”M” in the console or permanently in the settings editor. Preset orientations include Aiming (default), WiiWheel, Upright, Classic and there’s also Manual which depends on the config. To similarly change the orientation of the D-pad buttons press “D” or edit the default in the settings editor.

Note 2: MotionPlus hardware is autocalibrated a few seconds after launch and also manually with “C”. The Remote should be on a standstill during calibration. Also a motion client (Cemu or Padtest) expects the remote to be physically at the orientation preferred when they start (pressing “A” on the Remote itself resets the view on Padtest).

Step 6: Have Cemuhook in Cemu.exe’s directory. Use the latest version from here. This step is not strictly required for all features, but it allows Cemu to receive motion data and non-XInput button data.

Note: Cemu 1.18.0 supports Cemuhook’s API natively so Cemuhook is not required to be installed from that version onwards (note that the same version also supports motion for the emulated Wii Remote).

Step 7: Launch Cemu.exe, select a motion source now detected in the Options->Gamepad motion source menu (next pic). If you elect to not use XInput’s binds, you can select “Also use for buttons/axes” (you can reconfigure buttons for that feature in the settings editor). “By Slot” or “By MAC” only affects behavior if there are multiple remotes; by selecting a remote by MAC it will be remembered as the motion source regardless of order of detection (Cemu and Cemuhook currently only support one motion source).

Step 8: Choose GamePad as controller 1, and also select “Controller #” under XInput and set up the buttons (or leave them be if you use the “Also use for buttons/axes” feature).

Note: Cemu 1.18.0 added motion support on the emulated Wii Remote itself.

Note: Cemu 1.11.5 onwards added emulated wiimotes but for some games it’s mainly for booting and not playing them yet, and Cemuhook does not support motion servers for it.

Note: Shaking a Nunchuk or a Remote corresponds to certain buttons. This behavior can be configured or removed in the settings editor.

Step 9: Load a game

Caveats/Notes:

1. Bluetooth pairing can be ..an adventure on Windows. WiimoteHook now has a built-in pairing method but if that fails (possibly because of an unsupported bluetooth stack) you can try standard windows tools for pairing and in some cases physically reconnecting an adapter, rebooting or removing a pairing might help. While Windows 7 or older installations can pair with the new Remote Plus devices, they require the Toshiba bluetooth stack to properly communicate with them; Windows 10’s default method asks for a pin, but you can avoid that problem by “adding” it in “devices and printers” and click next when asked for a pin without entering one.

2. DolphinBar works on mode 4 + it’s normal to always return 4 devices and few of them to be detected as bogus + reconnecting it to another usb port often helps.

3. Linux is partly supported now that we’ve added raw Bluetooth HID support in Wine (originally inspired for this software). Details/Instructions are here.

Known bugs or limitations:

1. Cemu 1.11.5 onwards includes emulated wiimotes in input settings but for some games it’s mainly for booting and not playing them yet, and Cemuhook does not support motion for it. Update: Cemu 1.18.0 added support for motion with the emulated Wii Remote too.

2. Multiple(unlimited) Wiimotes are supported, however motion only works for the first Cemu GamePad chosen as the first controller (this is a Cemu and Cemuhook limitation).

3. Static MotionPlus calibration data are not fully reverse engineered. If your MotionPlus gets inverted axes you can switch that with the settings editor.
