Game data control program, game data overwriting program and game data overwriting device

A computer-readable recording medium, storing a game data control program for arranging game data in an internal memory of a video game device for use in a game process, the game data including a plurality of game parameters representing a status of a game stored in an external storage medium connected to the video game device, wherein the game data control program instructs a computer to function as:

• a game data loader for loading the game data from the external storage medium to the internal memory;
• a storage area changer for changing a storage area for each game parameter which has been loaded to the internal memory, at a predetermined time during the game process such that each game parameter is arranged in a storage area that differs each time a game parameter is arranged;
• a data rearranger for rearranging the game parameters based on results of the storage area changing process by the storage area changer;
• arrangement information storage programmed logic circuitry for storing arrangement information in a specified area of the internal memory, when the game parameters are rearranged by the data rearranger, the arrangement information being information which directly or indirectly indicates the storage area for each game parameter;
• and
• storage area determination programmed logic circuitry for determining the storage area for the game parameter by referring to the arrangement information, when a game parameter in the internal memory needs to be referred to or overwritten during the game process, wherein
• the storage area changer changes the storage area for the game data in the internal memory by specifying an offset value for shifting the storage area for the game data as a whole in the internal memory;
• and
• the data rearranger rearranges the game data as a whole in the internal memory so that a storage position relationship between the game parameters is maintained, by using, as a base address, an address obtained by adding the offset value to a specified address of the internal memory.
