Did you ever have this working before? I tried to get the Radio Shack device to work with my classic controller and they just weren't compatible. I upgraded to Windows XP and lost the gameport on my sound card. I figured I would try something different and gave it a try with no luck. In the end it turned out that a file was deleted for the gameport driver by Windows or the soundcard installer. Never found out which but after re-installing everything worked fine. Toook the adpater back to the shack,
