The Motion FX Adapter for Playstation 2 basically turns your Dual Shock 2 for PS2 into a Six Axis PS3 controller.
Once the easy installation is complete (requires only 1 minute), you can control your game with motion on the Dual Shock controller!
Well calibrated, the product is very efficient, and can be switched on/off for the games you want to use it with.

Clip the MotionFX onto your Sony Dual Shock wired controller and MotionFX adds PS3 / Wii type motion control to your existing PS2 controller.
Now you can interact with PS2 games like never before.
