Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic game device that switches BGM (background music) in various ways according to the progress of a game.

[0002]

2. Description of the Related Art An electronic game apparatus which displays game contents on a monitor while executing game software and advances a game by using an operator's key operation as one of branching conditions, causes some BGM from a speaker or the like while the game is in progress. It is generally played back. This is the fun of the game
This is because we try to enhance not only our sight but also our hearing.

[0003]

However, in the conventional electronic game device, since the types of BGM that can be played back are limited and the playback order is uniformly set, the same game is repeatedly executed. However, there is a shortcoming that it gets tired. It is an object of the present invention to further improve the fun of the game from the viewpoint of hearing by switching the BGM to be reproduced variously according to the game progress situation (stage).

[0004]

In order to achieve the above object, according to the present invention, first storage means for storing first music information and second music information different from the first music information are stored. Second storage means, control means for controlling the progress of the game and instructing music information to be read out according to the progress status of the game, and selected from the first or second storage means according to the instruction of the control means. It is characterized by comprising a sound control means for reading out the music information in a general manner and a reproducing means for reproducing the music information read out by the sound control means.

In this case, the music change instruction of the control means can be constituted by referring to a sound table in which the type of music information corresponding to the progress of the game is written in advance. Further, the type of music information stored in this sound table can be rewritten arbitrarily.

[0006]

According to the present invention, when the progress status of the game is classified into, for example, a plurality of stages, the music (BGM) to be reproduced for each stage can be selectively changed by the first and second storage means. Therefore, the fun of the game can be stimulated from the viewpoint of hearing. Moreover, if a large number of pieces of music information are prepared in advance, various kinds of music can be changed, so that the user is not tired of repeatedly playing the same game. In particular, by allowing the user to arbitrarily select the desired music, the fun from the viewpoint of hearing is further improved.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an electronic game device according to an embodiment of the present invention. In the figure, 1 is a main CPU that controls the progress of the game, 2 is a monitor that displays the contents of the game in progress, and 3 is provided with a cursor key K and shoot keys A and B that the user operates while the game is in progress. Controllers (key operation units) 4 are speakers (sound devices) that reproduce BGM during the game progress. Main CPU1
When the game software is executed, the contents displayed on the monitor 2 are sequentially updated, and one of the branching conditions is a key input from the controller 3. It is common to general games that the progress of the game changes according to this key input.

Reference numeral 5 is a ROM cartridge corresponding to the first storage means, in which the first music information (musical tone data G in this example) is stored for a plurality of songs. On the other hand, 6 is a ROM using a CD (compact disc) corresponding to the second storage means, that is, a CD-ROM, in which second music information different from the first music information (musical tone in this example) is used. Data G and sound data O) are stored for a plurality of songs. For example, the ROM cartridge 5 stores the musical tone data G for 10 songs distinguished by the sound numbers 00, 01, 02, ... 09, and the CD 6 has the sound numbers 10, 11, 12 ,. The musical tone data G of 10 songs to be distinguished and the sound numbers 20, 21, 22,
The acoustic data O for 10 songs distinguished by 29 are stored.

The analog sound data O input to the speaker 4 and reproduced is the sound data O read from the CD 6 or one piece of the musical sound data G previously written in the CD 6 or the ROM cartridge 5. The data is collectively read into the RAM 7, read by the sound CPU 9 at the tempo of music performance, transferred to the tone forming means (tone generator) 8, converted, and output.

The main CPU 1 is provided with a game control means realized by software, controls the progress of the game, and gives an instruction to change the music to be played according to the progress of the game. In this case, the control means issues a change instruction by referring to the sound table 10 in which the number of the music information to be read corresponding to the progress of the game is written in advance. The type of music information stored in the sound table 10 can be arbitrarily rewritten by the user using the controller 3.

FIG. 2 is an explanatory diagram showing an example of the sound table 10. The table 10 is set in a part of the RAM 7, for example, and has a configuration in which a sound number can be written for each stage of the game. When setting (changing) this sound number, for example, a number changing mode different from the game mode is set, and in this number changing mode, a number changing screen as shown in FIG. 2 is displayed on the monitor 2. Then, each stage is displayed in order, and the user increments or decrements the number of the sound number part of the stage with the cursor key K to change it to the desired number, and press the key A or the like. Try to confirm. By performing this operation for each stage, the sound number desired by the user can be arbitrarily set (changed).

FIG. 3 is a schematic flowchart showing the processing of the main CPU 1. When the power source of the apparatus is turned on, first the initialization in step S1 is performed, and thereafter, step S2 is performed.
To each step S4 are repeated. Step S2
Is a game progress control necessary for the progress of the game. In this game progress control, assuming, for example, an aerial battle game, (1) operation detection of keys A and B of the controller 3,
(2) Operation detection of cursor key K of the controller,
(3) Comparing the coordinates of the enemy plane and the coordinates of the own bullet (judgment of the enemy plane), (4) Comparing the coordinates of the own plane and the coordinates of the enemy bullet (judging of the enemy plane), (5) Game progress status Drawing processing according to the (stage) is performed.

In step S3, it is determined whether or not a stage change condition (for example, a predetermined number of enemy planes have been shot down or a predetermined time has elapsed after entering one stage) is satisfied. If the condition is satisfied (Y), the process returns to step S2 through step S4. In step S4, BGM change control is performed, and the sound CPU 9
Issue a sound change instruction to. The sound CPU 9 includes a sound control means having a software configuration for reading the corresponding music information from the ROM cartridge 5 or the CD 6 in accordance with a sound change instruction from the main CPU 1.

FIG. 4 is a schematic flowchart showing the processing of the sound CPU 9. In this process, after initialization at step S11 when the power is turned on, the processes after step S12 are repeated. In step S12, it is determined whether or not there is a sound change command from the main CPU 1.
If it is determined that there is a sound change command (Y), the sound table shown in FIG. 2 is referenced in step S13, and the sound number corresponding to the stage next to the current stage is read. Then, in step S14,
The read sound number is determined, and it is determined whether or not it is acoustic data O (sound number 20 to 29). If it is determined that the data is acoustic data, step S
At 15, the acoustic data of the corresponding sound number is read from the CD 6, is output to the acoustic device (speaker 4), and the process returns to step S12.

On the other hand, if it is determined in step S14 that the sound number is not acoustic data, that is, the musical sound data G, it is determined in step S16 from the data area of the storage means (ROM cartridge 5 or CD6) according to the sound number. Sound number data G (00-00)
09 or one of 10 to 19) is collectively read and is written in the RAM 7. Thereafter, in step S17, the musical tone data G in the RAM 7 is sequentially transferred to the musical tone forming means (tone generator) 8. The transfer timing is determined by the music progression control (stepping the address to the RAM 7 or the like) in the next step S18, and the output sound data O of the musical sound forming means 8 is adjusted so as to have a tempo as a music. After executing step S18, the processes of steps S17 to S19 are repeated until a change instruction is given.

When it is determined in step S12 that there is no sound change command (N), the process of step S13 is omitted and the process proceeds to step S14. In addition, step S13
In the process (1), when the CD 6 is not connected despite the sound number of "10" or more being designated, the abnormal process is performed in which all the tenth digits are regarded as 0. For example, in the case of stage 3 in FIG. 2, the sound number “12” is read as “02”, and in the case of step S4, the sound number “23” is read as “03”. By doing so, it is possible to use only the standard ROM cartridge 5 and avoid a silent state due to an erroneous selection when the CD 6 is not connected.
