You have most likely either heard or read on the internet that you can upgrade a 2001 through 2005 Golden Tee or a Buck Hunter 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.
The first thing you should do to verify that you do not have a bad gun is to use the test menu and attempt to calibrate both guns. To do this, first press the self-test button in the game or the slide switch on the PCB (labeled test switch) to get the game into self-test mode.
