Description

[Detailed description of the invention] The invention relates to a video game device, and particularly
This invention relates to a multi-television game device in which a CRT display is divided into multiple parts and used in multiple ways, allowing multiple games to be executed simultaneously on one device.

Conventional video game devices are generally devices dedicated to playing only one game.
Therefore, in order to play multiple games, it was necessary to prepare multiple devices. However, the internal structure of a video game device is generally the same regardless of the type of game, and the only difference is the program used to run the game. Therefore, the conventional method of only being able to play one game on one device was wasteful.

By the way, an object of the present invention is to provide a television game device that can execute a plurality of games with one device. According to the present invention, its purpose is to provide an image memory section that stores image display data for a CRT display and whose storage area is divided into a plurality of sections according to the number of games, and a scanning start signal and a blanking signal for the CRT display. a scanning signal generating section that generates a scanning signal generating section that generates a scanning signal, a game program starting signal generating section that generates a signal at a timing obtained by dividing a scanning period between the scanning start signal and the blanking signal according to the number of games, and the game program starting signal. A multiplayer game machine characterized by comprising a game execution unit that time-divisionally executes programs for each game that are executed in response to each game and rewrites the image memory unit that is executed in response to a blanking signal. - Achieved by providing video game devices.

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows a block diagram of the main parts of this embodiment. In this embodiment, two games (game 1 and game 2) can be played simultaneously on one device. 1 is an image memory section which is divided into two areas: game 1 and game 2. FIG. 2 is a timing chart for explaining the operation of each part of the apparatus shown in FIG.

In the present invention, various signals are generated according to various signals generated from the timing signal generator 6. For example, the scanning signal generating section 2 generates a scanning start signal and blanking signal for the CRT display, and the game program starting signal generating section 3 generates starting signals for starting the programs of game 1 and game 2. and synchronization signal generator 7
A signal is generated for synchronizing the video signal and the CRT display circuit section, which will be described later.

The relationship with the scanning start signal is as shown in FIG. The scan start signal is almost the same as a general scan signal and consists of scan start signals a ₁ , a _{2 .} . . and blanking signals b ₁ , b ₂ . The respective activation signals for game 1 and game 2 have scanning periods c ₁ ,
c ₂ ... is generated at the timing when the inside is divided according to the number of games 2.

Game program 5 based on the above signals
The game execution unit 4 executes the game. The program 5 includes programs for rewriting the game 1, game 2, and the image memory unit 1. And the program for game 1 is period G1,
The program for the game 2 is executed during the period G2, and the rewriting to the image memory unit 1 is executed during the periods d ₁ , d ₂ .
Note that the periods G1 and G2 are obtained by dividing the scanning periods c ₁ , c ₂ . . . . Furthermore, input signals from the game player (for example, signals from switches, knobs, etc. provided on the device) are input for each game.

The execution operations performed by the game execution unit 4 (specifically, the microprocessor) are as shown in FIG. That is, when the activation signal for game 1 is generated, the program for game 1 starts executing. The operation includes, for example, rewriting the information necessary for the game progress stored in the working memory 8 according to the input signal information of the game 1, and rewriting the necessary audio signals etc. according to the information. Output a signal. The audio signal generator 10 outputs an audio signal according to its output. Furthermore, when the activation signal for game 2 is generated, the same operation as described above is performed for game 2. Next, when blanking signals b ₁ , b _{2 .} . . of the scanning signals are generated, the necessary portions of the image memory section 1 are rewritten according to the information stored in the working memory 8. The rewriting is performed by outputting the address from 13 in the figure (which passes through MPX and becomes address 14) and the corresponding rewriting data from 15.

MPX (multiplexer) 11 outputs an address signal 1 as a scanning signal for displaying an image on a CRT.
2 and an address signal 13 for rewriting the image data, these two inputs are periodically and alternately opened and closed by a gate opening/closing signal generated by the timing signal generator 6, and the address signal 1 is generated.
Output as 4.

Image display on the CRT display is automatically performed independently of the game execution section 4.
This image display is performed simultaneously during scanning periods c ₁ , c ₂ .
2 (in Fig. 2) passes through the multiplexer 11 as an address signal for image data scanning and becomes address 14, and the data in the address section specified by this address 14 is read out and scanned as a black and white video signal. It is output to the data output section, and then this is the VIDEO signal and the color signal mixing section 9.
The video signal is mixed with the color data outputted from the color pattern generating section 16 and outputted, and the predetermined color VIDEO signal is inputted to the CRT display circuit section. (In the case of black-and-white video games, there is no color pattern generator, and the black-and-white data is used as a video signal as is.
input to the CRT display circuit).

As explained above, according to the present invention, in response to the generation of the scan start signal and the game program start signal,
Execution of the program for each game and rewriting of the image memory section are performed in a time-sharing manner, and scanning for image display is performed while the programs of multiple games are being executed, and rewriting is performed during the blanking period. Such a device is extremely advantageous in that it allows a plurality of games to be played simultaneously with one device.
