I haven't played much DK, but I do remember the stock joystick because it was annoying. You could move it in one of only four directions and there is a guide slot so you can't go directly from one direction to another -- you must move through zero first. The stick shown, regardless of whether or not it's an eight-way, may not have the same guide slot, the absence of which would provide a game play advantage.
