Total Claims: 12
Claim 1
Independent Claim
143 words
A video game system for executing a video game program and generating game play graphics for display on a user's display comprising: a game processing system for executing a video game program and generating game play graphics on a user's display; communications circuitry, coupled in use to said game processing system and to a user's communications network, for linking said game processing system to a server; a writeable mass storage device coupled in use to said game processing system for storing at least graphics data loaded therein, wherein said writeable mass storage device has a unique security code associated therewith, a mass storage device controller including cryptographic processing circuitry for performing encyption operations using said unique security code, for controlling access to said writeable mass storage device, and for generating a game request packet and transmitting the game request packet to said server.
Claim 2
Dependent Claim
143 words
A video game system for executing a video game program and generating game play graphics for display on a user's display comprising: a game processing system for executing a video game program and generating game play graphics on a user's display; communications circuitry, coupled in use to said game processing system and to a user's communications network, for linking said game processing system to a server; a writeable mass storage device coupled in use to said game processing system for storing at least graphics data loaded therein, wherein said writeable mass storage device has a unique security code associated therewith, a mass storage device controller including cryptographic processing circuitry for performing encyption operations using said unique security code, for controlling access to said writeable mass storage device, and for generating a game request packet and transmitting the game request packet to said server.
Claim 3
Dependent Claim
39 words
A video game system according to claim 1 , wherein said unique security code is a unique ID associated with said mass storage device which is associated with at least one encryption key that is used during encryption processing.
Claim 4
Dependent Claim
48 words
A video game system according to claim 1 , wherein said mass storage device is operable to store a partition table defining the mass storage device partitions which are accessible to a game program and wherein said mass storage device controller is operable to maintain said partition table.
Claim 5
Dependent Claim
33 words
A video game system according to claim 1 , wherein said mass storage device controller cryptographic processing circuitry includes processing circuitry for decrypting encrypted game program instructions accessed from said mass storage device.
Claim 6
Dependent Claim
27 words
