Wat doet de rapid fire mod met je ps3 controller?

letterlijk geciteerd: "The game controller that comes with the PlayStation 3 is a solid and dependable performer. What it lacks is a rapid-fire button so you can mow down your opponents in games where the speed of shooting is more important than accuracy. You can modify, or "mod" the PS3 controller so that it will have rapid fire capabilities. The modification will require opening the controller and installing a special circuit board that you can purchase from a PlayStation parts supply store. No special electronic skill is needed other than being proficient with a soldering iron. The PlayStation 3 console is not altered in any way."
