System 7 games have the software revision identified with an “L” to signify the Level of software release. 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.
Flipper and Sound/Speech ROMs:
All System 7 games, except for #509 (Hyperball), #517 (Defender), and #530 (Starlight) use the BLUE flipper ROMs in positions IC17 and IC20. These are common between all games. Every game software file here includes images of these ROMs.
