A peripheral device is provided for connection to a home video game system having a recess formed in an external surface thereof. The peripheral device includes an electrical component, an electrical connector coupled to the electrical component for connecting to a connector of the home video game system, and a housing. The housing of the peripheral device is configured so that when the peripheral device is inserted in the recess of the home video game system, it is substantially flush with the external surface of the home video game system. In this way, the footprint of the video game system can remain the same, even if peripheral devices are added.
