It is getting hard to find sound cards with a game port on them. I've found that an easier solution is to purchase a USB game controller and use it instead. I found one at a local store for about $10.00. It is very basic, no joystick, but all you need is the buttons. You can open it up and hardwire external buttons in place of the ones on the game controller. Just hide the cheesy looking USP controller, and nobody will be the wiser.
