Game apparatus, wireless module and game system

Abstract

A master wireless module transmits a beacon signal to a client wireless module in the same cycle as a game processing cycle. Each of the master wireless module and the client wireless module outputs an interrupt signal when a transmission time of the beacon signal arrives. A game processing section of each of the master wireless module and the client wireless module adjusts a V counter based on the interrupt signal. Therefore, it becomes possible to easily synchronize, when a multiplayer gameplay is performed using a plurality of game apparatuses capable of performing wireless communication with each other, times at which the plurality of game apparatuses execute predetermined processes.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] The disclosure of Japanese Patent Application No. 2006-285379, filed Oct. 19, 2006, is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a game apparatus, a wireless module and a game system, and more particularly to a game apparatus, a wireless module and a game system capable of realizing a multiplayer gameplay using a plurality of game apparatuses capable of performing wireless communication with each other. [0004] 2. Description of the Background Art [0005] Conventionally, there is a technique in which other game apparatuses each adjusts a transmission time of a signal based on a reception time of a signal transmitted from a reference game apparatus (Japanese Laid-Open Patent Publication No. 2000-135380 (hereinafter referred to as “patent document 1”), for example). [0006] Conventionally, there is also a technique in which a master game apparatus tra...

Benefits of technology

[0011] Therefore, an object of the present invention is to provide a game apparatus, a wireless module and a game system capable of easily synchronizing, when performing a multiplayer gameplay using a plurality of game apparatuses capable of performing wireless communication with each other, times at which the plurality of game apparatuses execute predetermined processes.

[0021] The wireless module may include interrupt signal outputting means of outputting an interrupt signal in a constant cycle based on the value of the timer, and the adjustment section may adjust a time at which the predetermined process is executed based on a time at which the wireless module outputs the interrupt signal. Thus, a change in the value of the timer included in the wireless module can be minimized.

[0035] According to the present invention, it becomes possible to easily synchronize, when performing the multiplayer gameplay using a plurality of game apparatuses capable of performing wireless communication with each other, times at which the plurality of game apparatuses execute the predetermined processes.

Problems solved by technology

Furthermore, in the technique disclosed in patent document 2, the master game apparatus needs to transmit the time information to the client game apparatus on a regular basis, thereby correspondingly deteriorating a usage efficiency of a communication line.

However, in the case where the technique disclosed in patent document 3 is applied to wireless communication, problems such as delay and jitter occur, thereby making it impossible to easily apply the technique disclosed in patent document 3 to wireless communication.
