Saitek P220

I bought this gamepad primarily because I wanted to play Mortal Kombat with it. :-) I tried it with the following games in alphabetical order:

Burger Time
Mortal Kombat
Money Puzzle Exchanger
Ms Pac-Man (the game I play 99% of the time in MacMame and the first one I tried)
Qix
The King of fighters 98
Popeye
Pulstar
Raiden
Sinistar
Tapper (Budweiser)

I didn't have to install any drivers. The games just work. The only minor problem I found was that the games started without sound. Once I pressed the ESC key, sound started playing.

Some of the buttons in Mortal Kombat don't correspond with the buttons in the controller, but I am confident I will be able to remap them.

Overall, I am very happy with how the controller works in MacMame.
