This is a Dualshock 2 compatible controller for the PS2. The layout of PlayStation 2's Dual Shock 2 controller is nearly identical to that of the original PlayStation's Dual Shock controller. The main new feature is that, when the buttons are pushed, the controller can register how much pressure is being exerted. This adds a completely new dimension to sports, racing, fighting, and more games that support this feature. Aside from the Start and Select buttons, all of the functions are analog for greater control and a wider variety of operations. Two convex analog thumb pads and twoforce-feedback solenoid rumblers round out the features. This PS2 Dualshock 2 compatible controller is also compatible with all software that supports the original Dual Shock controller.
