You have most likely either heard or read on the internet that you can upgrade a 2001 through 2005 Golden Tee board by simply adding a hard drive/compact flash card or changing out U53 (security IC) and have the 2006 Complete. THAT IS SIMPLY NOT TRUE AND CANNOT BE DONE!!!!!

If you have an NFL Blitz / NBA Showtime Vegas system, you should note that it uses a Voodoo video card. The Gauntlet and or WAR Final Assault Vegas system uses an Obsidian video card, which means that you cannot run the NBA Showtime on a Gauntlet system without changing out the video card to the Voodoo card, and vise versa for the Gauntlet on the NBA Showtime system.
