ABSTRACT:
A game cartridge includes a main cartridge which has a primary graphics memory unit, a first edge-board contact that is connected removably to a television game console and that enables the television game console to address and receive data from different storage locations in the primary graphics memory unit, and an edge-board connector that is connected electrically to the primary graphics memory unit and to the first edge-board contact. An auxiliary card has a secondary graphics memory unit and a second edge-board contact that is connected removably to the edge-board connector. A logic select circuit detects an address input from the television game console corresponding to a predetermined one of the storage locations in the primary graphics memory unit. The logic select circuit disables the primary graphics memory unit and enables the secondary graphics memory unit upon detection of the address input to permit the secondary graphics memory unit to replace the predetermined one of the storage locations in the primary graphics memory unit when the auxiliary card is attached to the main cartridge.
