My son wants me to play this game with him online. I have installed the game and it says this card is not supported. Says I need a card with dual-TMU support. What is that? I know a new card would probly work but I like my voodoo card (V5 5500) and a lot of my games are optimized for 3DFX.

Wrong or just too old driver. Install the SFFT Alpha 32 and it should work fine. :-)
