Abstract

Abstract A TV game machine (10) having a connector for detachably connecting a memory cassette (30) having at least non-volatile memories (34) containing a game program (344), picture data (341) and sound data (342-343), a processor (13) for executing the game program for the game while processing the data from the memory cassette based on the instructions of an external control means (50,50') for giving instructions to the game program. Further, it has a work RAM (20) for temporarily memorizing the progress of the game program, and a connector (21) for detachably connecting an IC card (40) including a RAM (41) having a backup power supply (42). The processor is adapted to save the progress of the game stored in the work RAM (20) in the RAM (41) in the IC card (40) and to read the progress of the game saved in the IC card into the work RAM to allow the game to be resumed from this state.

Claims Analysis

Total Claims: 6

Claim 1

Independent Claim 144 words

A TV game machine comprising a first connecting means for detachably connecting a memory cassette comprising at least non-volatile memories containing a game program, picture data and sound data; a processor for executing the game program for said game while processing the data from said memory cassette based on the instructions of an external control means for giving instructions to the game program; a work RAM for temporarily memorizing the progress of said game program; and a second connecting means for detachably connecting an IC card including a RAM having a backup power supply; said processor being adapted to save the progress of the game stored in said work RAM in the RAM in said IC card and to read the progress of the game saved in said IC card into said work RAM to allow the game to be resumed from this state.

Claim 2

Dependent Claim 93 words

A games machine including a processor and first memory means storing a games program and games data, the processor being responsive to the operation of a user-operable control means for executing the games program, the machine further comprising non-volatile, writable, second memory means into which the processor is operable to load information relating to the status of the game, whereby the status can be stored while the machine is unpowered, and from which the processor is operable to read said status information to allow the game to be resumed at a later stage.

Claim 3

Dependent Claim 16 words

A machine as claimed in claim 2, including a detachable module housing said second memory means.

Claim 4

Dependent Claim 19 words

A machine as claimed in claim 2 or claim 3, including a detachable module housing said first memory means.

Claim 5

Dependent Claim 70 words

A machine as claimed in any one of claims 2 to 4, the machine further comprising a work memory which is used by the processor throughout the progress of the game and which temporarily memorises said progress, the processor being operable to load information relating to the status of the game into the second memory means by transferring said status information from the work memory to the second memory means.

Claim 6

Dependent Claim 34 words

A machine as claimed in any one of claims 2 to 5, wherein the second memory means comprises a volatile memory circuit, and a battery for maintaining the contents of the volatile memory circuit.
