To see what version your game is running, set your test switch to AUTO/UP and press ADVANCE while in Game Over mode. You will see "2GGG" in the player 1 display, where GGG is the game number. The player 2 display will show the number of the installed game revision.

All Sound and Speech ROMs for the System 9 games are included with the game ROM file. Not all games use all chips, and the chip size varies per game.
