Character body IK and new hands
Wiicompiled VR PLUS v1.3 brings the selected racer's body and textured hands into the first-person cockpit on Windows and Quest standalone.
- Tracked arms and hands follow the VR controllers, with fixed palm-centre calibration profiles for all 24 original characters.
- The character's head is hidden. A Character hands only option keeps the character hands while hiding the torso and arms; Character body IK can also be disabled in VR settings → Cameras.
- Hands are smaller, arm thickness and reach fit the tracked controllers, and close hand positions no longer force oversized folded arms in front of the view.
- Cockpit height and wheel reach adapt to small and tall characters, including Waluigi and King Boo. Wide torsos have additional eye clearance without moving the native seat and legs out of place.
- The torso remains stable during turns and drifts. Legs retain driving and drift movements, while trick jumps and raised-leg boost celebrations are suppressed, including animation blends after the mini-turbo timer ends.
- Native steering-wheel detection fixes contributed by iChris4: topology handling and node matrix retrieval / topology validation.
The roadmap now marks new hand models and fix character height as done. Existing multiplayer, Wheel Wizard, physical wheels/pedals, comfort modes and Windows/Quest functionality remain included.

All packages require your own clean PAL RMCP01 Mario Kart Wii disc image. No ROM, Nintendo game assets or translated game executable is distributed. Windows users must run setup/rebuild to apply the new runtime; Quest users must rebuild their locally installed games with the new app's game kit. Preserve your saves and configuration when updating.
Validation and limits
Eight targeted regression suites pass; the Windows games compile and generated dispatch tables validate. The final cockpit and animation changes were tested in a Windows headset. The Quest APK is rebuilt and its package contents checked; the new body IK changes have not yet received a separate Quest headset test.
This is seated body IK, without tracked feet or individual fingers. King Boo uses character hands only; Miis and unsupported custom skeletons retain the fallback behavior. More character/vehicle/hardware coverage is welcome.
Built on WiiCompiled, Aurora and iChris4's OpenXR port. Full credits and feature documentation are available on the Wiicompiled VR PLUS project page.
