Dolphin, the GameCube and Wii emulator - Forums

You realize the gamecube can only turn so fast, you still have to emulate the hardware to do what the gamecube expects as a full press to the left or to the right... you can't use it to increase accuracy much as it will still only press the stick to the max it can go to... so it will only be so fast, this is because there's only so much of a range on the gamecube controller's analog sticks. So that even if you move the mouse really fast, the gamecube game/controller can only turn a set max speed.
