The Missile Command Multigame on-screen setup menu allows you to configure your game options without crawling into the cabinet to set DIP switches and allows separate configuration of Missile Command and Super Missile Attack options. The setup menu is also the place where high scores can be reset to the factory defaults.
To enter setup mode, place the game in self-test mode. The self-test switch is located inside the cabinet, usually above the coin box.
Once Self-test is started, the screen may appear to be frozen while making a low raspy tone. This indicates the memory test is in progess. After the memory test passes, there is a low tone followed by a high tone. The screen will now start to indicate the selftest progress. During testing of the pokey chip you should hear a series of tones that sound like a scale on a musical instrument.
When the self-test has completed, there should be a message on the bottom of the screen indicating that to enter setup mode you need to press both thebutton and buttons at the same time. The game should now transition into setup mode. See the screen shots below for what to expect.
Once in the setup mode, use the Trak Ball to move up and down within the menu or you can use theand buttons. The current selected item is highlighted in a different color than the other selections. To make changes to the current selected item, press any button. For each button press, the current selected field will toggle to the next option.
To save the settings and return to self-test mode, scroll down to the bottom item "save and exit", and press any fire button. At this point the currently displayed configuration will be saved and the game will return to self-test mode. It is at this point that high scores are erased if you selected that option.
If for some reason you wish to cancel your changes without saving them, simply take the game out of self-test without executing the "save and exit" option!
To return to game play mode after executing "save and exit" simply take the game out of self-test mode. The new settings will now have taken affect.
The SMA software has 3 levels of difficulty, and a 4th setting called "MC MODE". The "MC MODE" setting is the SMA version of Missile Command. SMA for backward compatibilty included a version of Missile Command. This version is slightly different from the Atari version, for instance the copyright notice on the bottom includes both "ATARI (C) 1980" and "GENCOMP (C) 1981". It is not known if there are any other differences in this software from the original Atari version. It is included in the multigame for completness and those who may be interested in playing it. Note: When using this setting it can sometimes be misleading and you may think the multigame is not working as each time you pressand buttons to toggle games, it appears that the game did not switch, but in reality it is switching between two very similar games. The only way to know which version you are playing is to check the copyright on the bottom.
