I have an old game controller that I really like using (Gravis PC GamePad), unfortunately, it has a 15 pin game port connector, and my computer does not have a game port (on board sound). I tried a Belkin game port to USB adapter, but it won't recognize, a buddy gave me a game port riser connector, but for the life of me I can't find a connector for it on my motherboard, I tried looking for a PCI game port card on ebay but they are all on sound cards, and I don't want or need another sound card. Anybody got any suggestions on how I could get this thing to work?
