boeingbus2002,
Did you try to install the software? My joystick software was allegedly WIn98, but installed OK under Win2k and Win XP.
You also need to check that after you plug in your USB-Game Port converter (but before you install teh joystick software or plug it in) that you have a "Standard Game Port" showing in device manager.
In Control Panel (Classic View), double click administrative tools, then computer management. Choose device manager in the left hand pane and in the right pane, scroll sown to "Sound, video and game controllers". In the hierarchy, you should have a "Standard Game Port". If not, this is a non-starter.
However, unfortunately, ORAC and Conan may be correct. There may be no way for this to work at all.
Let me know how it pans out.
