Mario Kart in VR
The Mario Kart in VR Setup:
Dolphin Emulator for Mario Kart Wii and VR Oculus Rift DK2 Support. Link
Oculus Rift DK2 for head and positional tracking.
Logitech G27 Steering wheel and pedals for Kart control.
All combined = Awesome
Next you need to remove the head of Mario Link and then use the Dolphin VR camera controls to position the camera to where his head was. Then enjoy a first person Kart race as Mario himself with proper scale and everything.
Here is some video of me trying it out, the jutter and sound issues are from the capture software Fraps, the bad driving is all me.
