So I gave this joystick an A for ease of installation BUT I put it in a three button Sega Genesis arcade joystick case and it required some ingenuity as the joystick wasn't really fits in stock The Sega arcade case was not designed for this. But with the help of my trusty Dremil to clean a couple of tabs on the case, my drill and pliers to change the base plate, and some Sanwa modifications (three washers, a cut of the spring holders and a little filing of the limiter), it fits. Hardly. But now I can enjoy all Sanwa style Genesis games! Oh, and the joystick connector also had to be re-pinned a bit to be on top etc.
