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.

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.

first embodiment

[0050]FIG. 1 is a block diagram illustrating a configuration of a game system according to a first embodiment of the present invention. Although the present embodiment illustrates an example where two game apparatuses (i.e., a first game apparatus 10a and a second game apparatus 10b) perform wireless communication with each other, the present invention is not limited thereto. The present invention is applicable to a case where three or more game apparatuses perform wireless communication with each other.

[0051] The first game apparatus 10a and the second game apparatus 10b are set to each other as communication parties for a multiplayer gameplay. For example, prior to starting the multiplayer gameplay, the first game apparatus 10a exchanges its own apparatus ID (which may be added with a user ID or a game program ID of a game program executed by the game apparatus 10a) with the second game apparatus 10b by wireless communication, and presents information concerning the second game a...

second embodiment

[0130]FIG. 9 is a block diagram illustrating the configuration of the game system according to the second embodiment of the present invention. The configuration shown in FIG. 9 is similar to that shown in FIG. 1 except that the TBTT interrupt signals are not outputted from the processors 123a and 123b to the interrupt circuits 16a and 16b, respectively, and therefore a detailed description thereof as shown in FIG. 9 will be omitted.

[0131] According to the second embodiment, as shown in FIG. 10, the game processing section 14a obtains the value of the TSF timer 124a (the TSF timer value) of the wireless module 12a on a regular basis in a cycle N times as long as 16.7 msec, thereby adjusting the V counter 181a based on the TSF timer value thus obtained. The same is also true of the game processing section 14b.

[0132] Hereinafter, described will be the flows of the processes executed by the game processing section 14a, the game processing section 14b, the wireless module 12a and the w...

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...
