An advantageous set of external interfaces for home video game platform provide modularity and expandability while maintaining and preserving the proprietary nature of the platform. A disk drive interface provides flexible communications with an internal disk drive. Various serial bus interfaces provide expandability and interconnectability with a variety of internal and external devices including, for example, flash memory, broadband adapters, modems, and various other devices. A 4-port game controller interface provides serial interconnectability with handheld game controllers and various other input/output device. Power supply, digital and analog audio/video connections, and parallel memory expansion connections are also provided.

External interfaces for a 3D graphics system

A video game system includes a game program executing system executing a game program and one or more controllers supplying user inputs to the game program executing system. An interface between the controllers and the game program executing system is programmable to periodically poll the controller without involvement of the game program executing system.

Controller interface for a graphics system

A video game system includes an audio digital signal processor, a main memory and an audio memory separate from the main memory and storing audio-related data for processing by the audio digital signal processor. Memory access circuitry reads non-audio-related data stored on a mass storage device and writes the non-audio-related data to the audio memory. The non-audio-related data is later read from the audio memory and written to the main memory.
