Well, I could not find a PCI Game port card. But I have heard of folks using a second cheap PCI sound card with a game port just for the game port. They let XP "discover" the new hardware, but ensured the new sound drivers were disabled - they had to be installed or XP would re-discover them, just disabled. One guy had to reinstall his sound drivers after. I think XP and the new sound card would behave - I just would not trust Creative to cooperate. So if you do this, make sure you back up all critical data and create a System Restore point, just in case you encounter problems.
