Here is your common
Famicom pirate controller. Because the connector at
the end of the cord doesn't fit the controller port
at the front of the Famicom, this controller is good
only for use on certain pirate consoles. It has your common
buttons along with Turbo A and B buttons. The wire
sprouts from the left side, just like the regular
Famicom controllers and you'll notice that there is
a bulge around all four sides of the controller that
will allow it to sit in the side slots of the
Famicom and some pirate consoles.

The Mule Joystick is not a joystick at all.
Something weird about
the controller is that it's called a joystick when
it's clearly not. Those Japanese dudes must see
things differently than us. Oh well.
