The Mad Catz Advanced Controller is very similar to the original N64 controller, so the only thing that you have to get used to is the fact that it?s comfortable. It does have a Slow feature, but I?m relatively sure no one out there ever uses this feature since games almost always have a series of options you can choose from when a game is paused, and the slow features simply bounce between pause and un-pause. There is also a Turbo fire feature you can set on your different fire buttons. The turbo button is placed in the center area of the controller, where it is easily accessed, but not accidentally so. If you want to use the Turbo feature, you?ll find it easy to set and clear. But the comfortable design is the real selling point on this controller. And for that, the learning curve is exactly zero. Just enjoy.
