Note

Food Fight is equipped with a self-calibrating joystick, which checks its maximum and minimum values while the game is being played. Initial values are set at the factory and stored in NVRAM. When Food Fight is turned off, the NVRAM values are updated. Each time Food Fight is turned on, the current values are read out of NVRAM. If NVRAM fails (see the description under Automatic Self-Test), then the joystick is recalibrated as the game is being played. In this case, the control will be sluggish for the first game or two after the game is turned on.

SWITCH TEST displays the state of the control panel switches, the joystick values, the coin inputs, and the dual-inline-package (DIP) switches as shown in Figure 2-3. A one (1) indicates that the switch is on, and a zero (0) indicates it is off. All eight bits are displayed for each direction of the joystick. Push both the one- and two-player start buttons to end this test.

See Chapter 1, Selecting the Options, for information on the settings of the DIP switch located on the game PCB.
