2. Description of the Related Art In a conventional game apparatus, when a detachable cassette containing a ROM in which a game program is stored, for example, is mounted, the game program is read therefrom, and characters and characters on a screen are read. Background display control or output control of music or sound is performed.

[0003] By the way, in order to attract the user's interest, if the game is complicated and a more realistic character is to be displayed or the character is to be operated, for example, the data of the character and the like are stored together with the game program. There has been a problem that the storage capacity is insufficient with the number of ROMs that can be built in the cassette and become large.

Therefore, as a storage medium for storing a game program, a storage medium having a large storage capacity and capable of reading data at high speed, for example, a CD-ROM or C
Optical discs such as DI have come to be used.

ROMs and CD-Is allow users to enjoy complicated and diverse games.

[0006]

By the way, in such a game apparatus, for example, a CD-ROM in which a program of a predetermined game such as a so-called car racing game is stored.
When a car racing game is played by using a car or a CD-I, for example, as each stage of the game is cleared, the maximum speed at which a car can go up is increased, and a car racing course (race course) becomes more complicated than before. It is changing, that is, the difficulty of the game increases as the game progresses, so that the interest of the user is not lost.

However, in this apparatus, the race course is displayed on the screen in accordance with the program stored on the CD-ROM or CD-I as described above. Then, when starting the game again from the beginning, the same race course that has been cleared once, that is, a race course known in advance is displayed, so that there is a problem that distracts the user's interest.

Further, when the game is completed to the end, all race courses are known, and there is a problem that a user's interest in the game is reduced.

In a so-called battle game in which a friend character (friend character) and an enemy character (enemy character) compete with each other, as each stage of the game is cleared, for example, the attack ability and defense of the enemy character and the friend character The ability is improved, that is, the difficulty of the game increases as the game progresses, but like the car racing game described above, the game pattern of the stage once cleared hardly changes, so There was a problem that distracted the interest of the elderly.

When the processing in step S1 of FIG. 7 is completed, the process proceeds to step S2 shown in FIG.
It is determined whether or not d (FIG. 2) has been operated and the reproduction of the audio signal from CD1 has started. If it is determined in step S2 that the reproduction of the audio signal from CD1 has not been started, the process returns to step S2, where
Step S2 is repeated until it is determined that the reproduction of the audio signal from CD1 has been started. Step S
If it is determined in step 2 that the reproduction of the audio signal from the CD 1 has been started, the process proceeds to step S3, in which a selection and setting process of the alligator 41 as a friendly character and a musician as a defense mode is performed.

Here, in this battle game, the musicians in the attack and defense modes are "POPS" (pops), "ROCK" (rock), "ENKA" (enka), and "CLASSI" shown in FIG.
"C" (classic). Attack and defense mode (hereinafter musician) "POPS"
Is an attack power of 200 and a defensive power of 50. Therefore, in a mode in which an attack is the subject, an energy coefficient X described later is RA
Level detection circuit 1 temporarily stored in M19 at 2 second intervals
X = (MAX−MIN) −3 (1) is calculated from the maximum value MAX and the minimum value MIN of the level value (the signal level of the audio signal reproduced from the CD1) of the level signal detected at 1.

The musician "ROCK" or "EN"
KA "have an attack power of 100 and a defensive power of 100,
Therefore, in the mode in which both the attack and the defense (defense) are balanced, the musician is temporarily stored in the RAM 19 at intervals of 2 seconds, based on the maximum value MAX and the minimum value MIN of the level value of the level signal detected by the level detection circuit 11. "RO
The energy coefficient X of the musician “ENKA” described below is expressed as follows: X = (MAX−MIN) −3 (3) Is calculated.

The musician "CLASSIC" has an attack power of 50 and a defensive power of 200. Therefore, in a mode in which the main body is defensive (defense), the energy coefficient X to be described later is R

X = 12− (MAX−MIN) (4)

In this battle game, as will be described later, the larger the energy coefficient X is, the more the energy coefficient X is increased.
However, more effective attacks and defenses can be made. Therefore, the musician "POP" for which the energy coefficient X is calculated by the equation (1) or (2), respectively.
When “S” or “ROCK” is selected as the attack and defense mode, the maximum value and the minimum value of the level value of the level signal (the signal level of the audio signal reproduced from the CD1) detected by the level detection circuit 11 The greater the difference from the MIN, the more effective the attack and defense, and the more powerful the attacker and the defender of the musician “ENKA” or “CLASSIC” whose energy coefficient X is calculated by equation (3) or (4), respectively. When the mode is selected, as the difference between the maximum value MAX and the minimum value MIN of the level value of the level signal detected by the level detection circuit 11 is smaller, more effective attack and defense can be performed.

In the step S3 in which the selection and the setting process of the musicians in the attack and defense mode of the alligator 41 as the ally character as described above are performed, first, in the step S31 shown in FIG.

If it is determined in step S41 that the stored value (musician number M) of the register M is 2 or 3, that is, the musician "ROCK" or "ENKA" is selected as the attack and defense mode. In this case, the process proceeds to step S44, where 100 is set in the register P indicating the attack power of the alligator 41 as the ally character, which is built in the game control unit 12 (FIG. 8). Is set to the register U indicating (FIG. 8), and the process proceeds to step S48.

Further, if it is determined in step S41 that the stored value of the register M (musician number M) is 4, that is, if the musician "CLASSIC" is selected as the attack and defense mode, the process proceeds to step S46. In the register P indicating the attack power of the alligator 41 as the ally character, 50 is set in the register P indicating the defense power of the alligator 41 in step S47. Is set (FIG. 8), and the process proceeds to step S48.

In step S48, the game control unit 1
A register E indicating the energy of alligator 41 built in
Is set to 6000 as an initial value, and the process ends.

When the processing of steps S31 to S48 shown in FIG. 9 is completed, that is, when the processing of step S3 shown in FIG. 6 is completed, in step S4 (FIG. 6), the alligator 41 can be used as an ally character. Selection and setting processing of a musical instrument as a weapon are performed.

In this battle game, 41 alligators can be used as musical instruments as weapons in FIG.
"GUITAR" (guitar), "PIANO"
(Piano), “SYNTH” (synthesizer), and “TRUMPET” (trumpet) are prepared. Alligator 41 is a weapon (hereinafter, musical instrument) "GUITA
In the case of attacking or defending using “R”, the energy coefficient X calculated according to any of the equations (1) to (4) is temporarily stored in the RAM 19 at intervals of 2 seconds. (The signal level of the audio signal reproduced from CD1)
Is corrected according to the following equation: X ← X + Y−3 (5)

When the alligator 41 attacks or defends using the musical instrument "PIANO", the energy coefficient X calculated according to any of the equations (1) to (4) is RA
Level detection circuit 1 temporarily stored in M19 at 2 second intervals
The average value Y of the level values of the level signals detected at 1 is corrected according to the following equation: X ← X + 12−Y (6)

Further, when the alligator 41 attacks or defends using the musical instrument “SYNTH”, the energy coefficient X calculated according to any of the equations (1) to (4) is stored in the RAM 19 for 2 seconds. X ← X + 10 (when Y is an even number) (7a) or X ← X−3, corresponding to the average value Y of the level values of the level signals detected by the level detection circuit 11 temporarily stored at intervals. (However, when Y is an odd number) It is corrected as shown in (7b).

The alligator 41 is a musical instrument "TRUMPET".
In the case of attacking or defending using, the energy coefficient X calculated according to any one of the equations (1) to (4) is temporarily stored in the RAM 19 at intervals of 2 seconds and detected by the level detection circuit 11. Regardless of the average value Y of the level values of the obtained level signals, the correction is performed in accordance with X ← X + 5 (8).

Here, the energy coefficient X is
Attacked the monster 44, the damage of the monster 44,
That is, the energy KE of the monster 44 (the stored value of the register KE)
Is used to determine a value for reducing the energy E (the value stored in the register E).

That is, as shown in FIG.
When the monster 44 is attacked, the energy KE (register KE) of the monster 44 is calculated according to KE ← KE−X × P by the energy coefficient X and the above-mentioned alligator 41's attack power P (stored value of the register P).
Is calculated (decreased), and when the alligator 41 replenishes its own energy E, the energy coefficient X and the defensive force U of the alligator 41 (the stored value of the register U)
Accordingly, 41 energy E (the value stored in the register E) is calculated (increased) according to E ← E + X × U.

Accordingly, the larger the energy coefficient X is, the more effective the alligator 41 can attack and defend. That is, the alligator 41 is the energy KE of the monster 44
(The value stored in the register KE) can be further reduced (the monster 44 can be damaged more), and the energy E of itself (alligator 41) can be further increased.

Therefore, when the average value Y of the level value of the level signal (the signal level of the audio signal reproduced from the CD1), which is temporarily stored in the RAM 19 at intervals of 2 seconds, is large. When the musical instrument "GUITAR" whose energy coefficient X is corrected by the equation (5) is used as a weapon, and the average value Y is small, the musical instrument "PIANO" whose energy coefficient X is corrected by the equation (6) is used as a weapon. When used as the alligator, the alligator 41 can provide more effective attack and defense.

Further, when the musical instrument "SYNTH" is used as a weapon, the average value Y of the level values of the level signals detected by the level detection circuit 11, which is temporarily stored in the RAM 19 at intervals of 2 seconds, is an even number. , Equation (7a)
, The alligator 41 can perform a more effective attack or defense, but the average value Y
Is an odd number, the energy coefficient X is corrected by the equation (7b), so that the attack capability and the defense capability of the alligator 41 are reduced.

When the musical instrument "TRUMPET" whose energy coefficient X is corrected by the equation (8) is used as a weapon, it is temporarily stored in the RAM 19 at intervals of 2 seconds.
Regardless of the average value Y of the level values of the level signals detected by the level detection circuit 11, the alligator 41 can perform more effective attack and defense.

In the step S4 in which the musical instrument as a weapon used by the alligator 41 as the ally character is set and set as described above, first, in step S51 shown in FIG. , 1 is set as an initial value in the register I (FIG. 4) indicating the musical instrument number, and the process proceeds to step S52, where the musical instrument “GUITA” is set.
R "," PIANO "," SYNTH ", or" TR "
A selection screen for selecting any one of “UMPET” is displayed on the display unit 13 (FIG. 11).

The musical instruments "GUITAR", "PIAN"
O, “SYNTH”, or “TRUMPET” is assigned with an instrument number 1, 2, 3, or 4, respectively. On the selection screen of the display section 13, the instrument number is set in a register I built in the game control section 12. The musical instrument corresponding to the selected musical instrument number is highlighted (FIG. 11).

When the selection screen is displayed on the display section 13, the CALL key 16a and the UP key 16 of the game operation section 16 are displayed.
b or the DOWN key 16c (FIG. 2) is operated to select and confirm (set) a musical instrument (weapon).

That is, in step S53, it is determined which one of the CALL key 16a, the UP key 16b, and the DOWN key 16c of the game operation section 16 has been operated. If it is determined in step S53 that the UP key 16b of the game operation unit 16 has been operated, the process proceeds to step S54, and it is determined whether the stored value of the register I is 1 or not. If it is determined in step S54 that the storage value of the register I is 1, the process proceeds to step S5
The process proceeds to step S5, where 4 is set in the register I.
