On the left hand portion of the SplitFish edgeFX you get a familiar joystick and D-pad along with the L1 and L2 button on the top of the controller just like you get on the Dualshock 2. There are also two additional buttons on the left controller that you don't see on the standard PS2 controller. One of them is a sensitivity dial wheel used to change the mouse sensitivity, making movements faster or slower.
