========================================================================
Game Identification (information sourced from internal Atari Vax emails)
All System I games are required to initialize a byte in the configuration area
(at 01006E specifically) to a certain value. The utility system on the main
board interrogates this byte to determine if a new game cart has been installed
and clears the EEROM accordingly.
Here is the list, which includes confirmed (*) and unconfirmed values:
Diagnostic Cartridge: 255
Peter Packrat: 000*
Marble Madness: 001*
Indiana Jones - Temple of Doom: 002*
Road Runner: 003*
Relief Pitcher (unreleased): 004
Off-Road (unreleased): 004
RoadBlasters (aka Future Vette):005*
