Abstract
A hand-held video game system having a microprocessor controller with address and data buses for providing memory accesses during memory cycles to a plurality of cartridge slots for electrically connecting cartridges containing memory to the address and data buses. An output terminal of the microprocessor controller provides cartridge-select signal which identifies a first memory containing cartridge to be accessed during an initial memory cycle with the microprocessor controller controlling the output terminal to change the cartridge-select signal for transparently accessing a second memory containing cartridge for a subsequent memory cycle. The cartridge slot may also provide a port for transferring and receiving information over a bi-directional communication link in which a communication cartridge allows communication over the internet, and allows for interactive play of a video game.
