Abstract: The purpose of the present invention is to provide a backup memory management system capable of indicating any misuse of data in a backup memory and imposing an appropriate sanction. The backup memory management device comprises a data saving system 10. When the generated and renewed parameter data is stored into the backup memory 3, the data saving system 10 determines whether or not parameter data already stored in the backup memory 3 is proper data, and if the parameter data is determined as proper data, the generated and renewed parameter data is written over the parameter data saved in the backup memory 3, and if the parameter data is determined as improper data, executes predetermined special processing. Special processing means processing such as imposing a penalty in the course of a game.

Abstract: A game device is provided which has a function to automatically compose background music without forcing a player to input complicated operations, while allowing the player to enjoy the game. A game processor (22) receives operational signals from a control pad (10) and thereby performs the game processing. An accompaniment parameter generator (25) receives, from the game processor (22), parameters relating to the status of the game and then generates an accompaniment parameter which corresponds to the status of the game. A melody parameter generator (24) receives the operational signals from the control pad (10), and then decides on scales, sound production starting time, note lengths and other necessary conditions by considering the operational signals as sound producing factors for a melody. The starting time for producing the melody is determined by referring to the sound producing timing of the melody which is included in the accompaniment parameter.
