VIDEO GAME MACHINE 
(VGM) OPERATION
STARTING UP
W henever you turn on the machine or restore power, the system executes boot ROM code. The boot
ROM contains self-diagnostic tests. These tests automatically verify and report the condition of the disk
drive and other hardware. The screen is blank during these tests. If the hardware fails a test, the system
displays an error message. The message appears for 30 seconds or until someone presses a button.
•
  If nobody presses a button, the system quickly completes tests, and then loads game software.
•
  To skip boot ROM tests and activate the Menu System, press and hold the TEST MODE button. You’ll
find this button behind the coin door.
Having passed power-up tests, the VGM computer enters Attract Mode. Attract Mode consists of typical
game scenes and sounds, alternating with high scores. Attract Mode continues until game play
commences.
Players insert currency or tokens to start the game. Pressing a START determines which player receives
the credit. The VGM computer asks the players which game that they want to play: NBA Showtime Gold
Edition or NFL Blitz 2000 Gold Edition. Players request one or the other via player panel controls. Then
players select a team. The VGM computer associates one team with the Player–1 and Player-2 joysticks.
The Player–3 and Player-4 joysticks assume control of the opposing team. Play begins after a countdown
period. Play progresses like a real-life football or basketball game. At Game-Over Mode, players may
choose to begin again. If players choose not to continue, then the VGM computer returns to Attract Mode.
