Abstract: Provided is a security system for managing which CD-ROM is used for a game device not having identifying information in advance. When a game device accesses a server via a communication network, a device ID, which is issued from the server, is stored in a nonvolatile memory This device ID is generated based on the time and date when the game device accesses the server via a communication network (e.g. Dec. 10, 2000 at 21:05:37). The server associates a serial number (SN) of a CD-ROM used in the game device and a device ID of the game device with each other and registers them on a database. This makes it possible to manage which CD-ROM is used in each game device.

Abstract: A data processing method is provided whereby, even if communication delay occurs between computer game devices connected through a communication network, data is processed practically simultaneously between the respective computer game devices. When a computer game contest is carried out through a network having communication delay, before the game is started, the delay times between the game devices are found and, using these, synchronization of the time counted by the individual game devices is obtained. Then, during the progress of the game, the operating data signal is processed after the lapse of the longest delay time of the delay times between the game devices measured beforehand after it is generated. In this way, the operating data signal can be processed simultaneously in a plurality of game devices.

Abstract: A game device enabling adjustment of the virtual viewpoint displaying a game character to be positioned to view the surroundings of the character in a broad range. When the manipulation character C stands still, the viewpoint of the virtual cameral 30 can move along the face of the exterior sphere 40B in accordance with manipulations of the game player. Upon collision with an obstacle, this virtual camera approaches the character in the direction of the face of the interior sphere 40A. However, the virtual camera does not approach the character C beyond the interior sphere.

Abstract: Although difficult game stages may not be cleared by unskilled players, by making the stages easy to be cleared, the degree of difficulty of the game would be lowered and the amusement of the game would be reduced. The present invention comprises: a storing device 102 capable of storing the number of certain marks displayed in an virtual space and which are in the player's hand, as well as displaying the position of such marks; a processing circuit 10 for advancing the respective steps of game control in sequence by referring to the operation signals supplied from an input device 2b, the number of marks in hand and positions thereof stored in the storing device, and for outputting displaying image data related thereto; a displaying circuit 11 for displaying a displaying image including the segment and marks on the basis of displaying image data supplied from the processing circuit.
