Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic game apparatus 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 proceeds with the game based on an operator's key operation as one of branching conditions, transmits some BGM from a speaker or the like while the game is in progress. It is generally playing. This is the fun of the game,
This is because they try to enhance not only sight but also hearing.

[0003]

However, in the conventional electronic game apparatus, the types of BGM that can be reproduced are limited, and the reproduction order is determined uniformly, so that the same game is repeatedly executed. However, there is a drawback that the user eventually gets tired. An object of the present invention is to change the BGM to be reproduced in various ways according to the progress of a game (stage), thereby further improving the fun of the game from an auditory point of view.

[0004]

In order to achieve the above object, according to the present invention, a storage means for storing music information serving as BGM of a game, and a main CPU for controlling the progress of the game
Music sound converting means for converting the music information into acoustic data; and a sound CPU for controlling transfer of the music information read from the storage means to the musical sound forming means based on a command from the main CPU. It is characterized by becoming.

[0005] In this case, the music change instruction of the control means can be made by referring to a sound table in which the type of music information corresponding to the progress of the game is written in advance. The type of music information stored in the sound table can be arbitrarily rewritten.

According to the present invention, when the progress of a game is classified into, for example, a plurality of stages, 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 stimulatively improved from the auditory point of view. Moreover, if a large number of music information are prepared in advance, a variety of music changes can be made, so that the user does not get tired of playing the same game repeatedly. In particular, by allowing the user to arbitrarily select the desired music, the auditory fun is further improved.

[0007]

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 one embodiment of the present invention. In the figure, 1
Is a main CPU for controlling the progress of the game, 2 is a monitor for displaying the contents of the game in progress, 3 is a controller (key operation unit) provided with cursor keys K and shoot keys A and B operated by the user during the progress of the game. ), 4 are speakers (sound devices) for playing BGM during the progress of the game. When the main CPU 1 executes the game software, the contents displayed on the monitor 2 are sequentially updated. One of the branch conditions is a key input from the controller 3. The progress of the game changes according to the key input, which is common to general games.

Reference numeral 5 denotes a ROM cartridge corresponding to a first storage means, in which first music information (musical sound data G in this example) for a plurality of music pieces is stored. On the other hand, reference numeral 8 denotes 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 (in this example, a musical tone). Data G and sound data O) are stored for a plurality of music pieces. As an example, the ROM cartridge 5 stores musical tone data G for ten songs distinguished by sound numbers 00, 01, 02,... 09, and the CD 6 has sound numbers 10, 11, 12,. The music data G for 10 songs to be distinguished and the sound numbers 20, 21, 22, 22
... Sound data O for 10 pieces of music identified by 29 are stored.

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

The main CPU 1 has game control means realized by software, controls the progress of the game, and instructs the change of music to be reproduced according to the progress of the game. In this case, the control unit issues a change instruction with reference 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, for example, in a part of the RAM 7, and has a configuration in which a sound number can be written for each stage of the game. When setting (changing) the sound number, for example, a number change mode different from the game mode is set. In this number change mode, a number change screen as shown in FIG. Each stage is displayed in order, and the number of the sound number portion of the stage is incremented or decremented by the cursor key K to a desired value, and the value is changed by the key A or the like. Make sure it is fixed. 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 supply of the apparatus is turned on, first, initialization of step S1 is performed, and thereafter, step S2 is performed.
To each step S4 are repeated. Step S2
Is game progress control necessary for game progress. In this game progress control, for example, when an air battle game is assumed, (1) operation detection of keys A and B of the controller 3;
(2) Operation detection of the cursor key K of the controller,
(3) Comparison of the coordinates of the enemy aircraft and the coordinates of the own munition (judgment of enemy hit), (4) Comparison of the coordinates of the own aircraft with the coordinates of the enemy bullet (judgment of the own hit), (5) Game progress Perform drawing processing according to (stage).

In step S3, it is determined whether or not the condition for changing the stage (for example, whether a predetermined number of enemy aircraft have been shot down or a predetermined time has elapsed after entering one stage) is satisfied. Returning to S2, if established (Y), the process returns to step S2 via step S4. In step S4, BGM change control is performed, and the sound CPU 9
To sound change instruction. The sound CPU 9 has software control means for reading the corresponding music information from the ROM cartridge 5 or the CD 8 in accordance with the 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 is performed in step S11 when the power is turned on, the processes in and after step S12 are repeated. In step S12, it is determined whether there is a sound change command from the main CPU1.
If it is determined that there is a sound change command (Y), the sound table corresponding to the stage following the current stage is read in step S13 with reference to the sound table shown in FIG. Then, in step S14,
The read sound number is determined, and it is determined whether or not the read sound number is sound data O (sound number 20 to 29). If it is determined that the data is acoustic data, step S
At step 15, the sound data of the corresponding sound number is read from the CD 6, output to the sound 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, it is determined that the sound data is the tone data G, the corresponding data is read from the data area of the storage means (ROM cartridge 5 or CD6) according to the sound number in step S16. Tone data G (00-
09 or one of 10 to 19) is collectively read and written into the RAM 7. Thereafter, in step S17, the tone data G in the RAM 7 is sequentially transferred to the tone generating means (tone generator) 8. This transfer timing is determined by the music progress control (such as stepping the address to the RAM 7) 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 issued.

If it is determined in step S12 that there is no sound change command (N), the process in step S13 is omitted, and the process proceeds to step S14. Step S13
In the processing of (1), if the CD 6 is not connected despite the fact that a sound number equal to or greater than "10" is specified, an abnormal processing 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 erroneous selection when the CD 6 is not connected.
