Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game device suitable for use in playing a game.

[0002]

2. Description of the Related Art In a conventional game machine, for example, when a removable cassette having a built-in ROM storing a game program is installed, the game program is read from the cassette, and characters on the screen are displayed. Background display control or music or voice output control is performed.

By the way, in order to attract the interest of the user, if the game is complicated and a more realistic character is to be displayed or the character is to be operated, the data of the character and the like will be stored together with the game program. There has been a problem that the storage capacity is insufficient due to the enormous number of ROMs that can be built in the cassette.

Therefore, a storage medium for storing a game program has a large storage capacity and is capable of reading data at high speed, such as a CD-ROM or C.
Optical discs such as DI have come into use.

In recent game devices, such a CD-
ROM and CD-I make it possible to enjoy a wide variety of complicated games.

[0006]

By the way, in such a game device, for example, a CD-ROM in which a program for a predetermined game such as a so-called car race game is stored.
When you play a car racing game by playing CDs or CD-I, as you clear each stage of the game, for example, the maximum speed that the car can drive increases, and the car racing course (race course) becomes more complicated than ever. The game is changing, that is, the difficulty level of the game increases as the game progresses, thereby keeping the user's interest.

However, in this device, since the race course is displayed on the screen according to the program stored in the CD-ROM or the CD-I as described above, for example, the game is interrupted midway. Then, when the game is restarted from the beginning, the same race course as once cleared, that is, a race course which is known in advance, is displayed, which causes a problem of intriguing the user.

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

Also in a so-called battle game in which an ally character (ally character) and an enemy character (enemy character) compete, as each stage of the game is cleared, for example, the attacking ability and defense of the enemy character and ally 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 it is also used There was a problem that intrigued the person.

Further, in order to play a game on such a game device, a CD-ROM storing a game program is stored.
Or CD-I (CD-ROM or CD-I dedicated to games) had to be purchased.

The present invention has been made in view of such a situation, and it is possible to play a game of various patterns at low cost.

C is read, and there, from TOC, step S11
The total number of songs recorded on the CD determined to have been set in step 1, the total time, and the time of the longest recorded song (longest song) are calculated.

That is, the value in the TOC is 00H to 9
Among points have become 9H (bit Q ₁₇ to Q ₂₄₎ (FIG. 5), a different number of all points of the value is counted, the total number of tracks N recorded on the CD is calculated.

Further, the points (bits Q _{17 to} Q ₂₄ ) in the TOC are referred to the bits Q _{57 to} Q ₈₀ of the Q channel of A2H (FIG. 5), and the absolute time (Mt minutes St) of the lead-out area of the CD is read. Second Ft frame) is detected. The absolute time (Mt minutes St seconds Ft frames) at the beginning of the lead-out area indicates the total time of the songs recorded on the CD (to be exact, all the songs and the pause between the songs). Including time).

The values in the TOC are 00H to 9
Among points have become 9H (bit Q ₁₇ to Q _24), it is referred to different all points Q channel bits Q ₅₇ to Q ₈₀ of its value, the beginning of the absolute time detection of each song recorded on the CD To be done. Then, the absolute time at the beginning of the nth song is subtracted from the absolute time at the beginning of the (n + 1) th song (n
, 1, 2, ..., N−1), of which the longest time, that is, the time of the longest piece of music (longest piece) recorded on the CD (M _max minutes S _max seconds F _max frames) ( To be precise, the true time of the song, including the time of the pause that exists after the song, is calculated.

Of the total number N of songs recorded on the CD, the total time (Mt minutes St seconds Ft frames), and the recorded songs calculated by the game control unit 11 as described above. The time of the longest song (longest song) (M
_max minutes S _max seconds F _max frames) are temporarily stored in a predetermined area of the game data memory 17 (FIG. 9), and the attack power or energy of the monster 32 is calculated by, for example, formula (1) or (2).
According to the above calculation, the process proceeds to step S14.

In step S14, step S13
The attacking power and energy of the monster 32 calculated in step 3 are displayed on the upper part of the monster 32 (FIG. 10), and the process ends.

After the processing of steps S11 to S14 of FIG. 8, that is, the processing of step S3 of FIG. 6, when the CD loaded by the player B is removed, the CD is loaded by the player A and the player A is loaded in step S4. The attack power and energy of the crocodile 31 as the character are calculated.

That is, in step S4, in steps S21 to S24 shown in FIG.
The same process as the process of replacing the monster 32 with the crocodile 31 in 11 to S14 (FIG. 8) is performed.
The offensive power and energy of are calculated and displayed.

As described above, by the processing of steps S3 and S4, as shown in FIG. 10, on the display unit 18, the energy of the monster 32 or the crocodile 31 to the left or right of the symbol EG indicating energy, for example, 4000 is displayed. Or 100
0 is displayed respectively, and the symbol P indicating the attack power is displayed.
On the left or right side of W, for example, 2400 or 2900 as the attack power of the monster 32 or the crocodile 31 is displayed, respectively.

Then, in step S5, the monster 32 is attacked or energy is replenished.

That is, in step S5, first, in step S31 shown in FIG. 12, it is determined whether or not the battle button 23a (FIG. 2) for the monster 32 to attack the crocodile 31 has been operated. When it is determined in step S31 that the battle button 23a is not operated, the process proceeds to step S32, and it is determined whether or not the energy button 23b (FIG. 2) for the monster 32 to replenish its own energy is operated. It

When it is determined in step S32 that the energy button 23b is not operated, the process returns to step S31, it is determined that the battle button 23a is operated in step S31, or the energy button 23b is operated in step S32. The processes of steps S31 and S32 are repeated until it is determined that they have been performed.

In step S31, the battle button 2
If it is determined that 3a has been operated, the process proceeds to step S33, and in order to store that the battle button 23a has been operated, the variable KF is set to, for example, 1 out of 0 and 1
Is set and the process proceeds to step S35.

On the other hand, when it is determined in step S32 that the energy button 23b has been operated, the process proceeds to step S34, and in order to store that the energy button 23b has been operated, it is stored in the variable KF among 0 and 1. Is set to 0, for example, and the process proceeds to step S35.

In step S35, the variable TIM is set to
The time (second) measured by the time counter built in the game control unit 11 is set, and the process proceeds to step S36.
The time counter is reset, and the process proceeds to step S37. In step S37, a clock is supplied from the game control unit 11 to the random number generation circuit 16, and the random number generation circuit 1
A random number is output from 6 and the process proceeds to step S38.

In step S38, step S13
The attack power of the monster 32 calculated in (FIG. 8) is multiplied by the random number output from the random number generation circuit 16, and the result is used as a score (described later).

Then, in step S39, the variable KF
Is determined. When it is determined in step S39 that the variable KF is not 1, that is, the monster 3
When the energy button 23b for replenishing energy of 2 is operated, the process proceeds to step S40, and the energy of the monster 32 is updated (replenished) according to the following equation from the score calculated in step S38. Step S
Proceed to 41. Energy of monster 32 ← Energy of monster 32 + score

In step S41, step S40
The energy of the monster 32 replenished by is displayed on the display unit 18 again, and the process ends.

On the other hand, in step S39, the variable KF
Is determined to be 1, that is, the monster 32 crocodile 31
When the battle button 23a for attacking is operated, the process proceeds to step S42, and in step S35, the variable TI
For example, it is determined whether or not the value of the time counter set to M is equal to the value obtained by multiplying the 100th digit of the energy of the current alligator 31 by 0.5.

Here, when the value of the time counter set in the variable TIM is equal to the value obtained by multiplying the 100th digit of the energy of the current crocodile 31 by 0.5, the score is a normal bonus. The monster 32 can deal twice as much damage to the crocodile 31 as will be described later.

If it is determined in step S42 that the value of the variable TIM is not equal to the value obtained by multiplying the digit of the 100th digit of the current energy of the alligator 31 by 0.5,
In step S43, the energy of the crocodile 31 is updated (decreased by the attack of the monster 32 against the crocodile 31) from the score calculated in step S38 according to the following equation. Energy of alligator 31 ← Energy of alligator 31-Score

In step S42, the variable TI
If it is determined that the value of M is equal to the value obtained by multiplying the digit of the 100th digit of the energy of the current alligator 31 by 0.5,
In step S44, the energy of the crocodile 31 is updated (decreased by the attack of the monster 32 against the crocodile 31) from the score calculated in step S38 according to the following equation:
It proceeds to step S45. Energy of crocodile 31 ← Energy of crocodile 31-score x 2

Therefore, the value of the variable TIM and the current alligator 3
If the value obtained by multiplying the 100's digit of 1 energy by 0.5 is equal, it is possible to do double damage to the crocodile 31 compared to the case where it is not. There is.

In step S43 or S44, the crocodile 31
After the energy of the crocodile 31 is updated (decreased by the attack of the monster 32 on the crocodile 31), the process proceeds to step S45, the energy of the crocodile 31 is displayed again on the display unit 18, and the process ends.

When the variable KF is 1, that is, when the monster 32 attacks the crocodile 31, flames are emitted from the mouth of the monster 32 (the flame is displayed at the mouth of the monster 32). Is supposed to be).

After the processes of steps S31 to S45 of FIG. 12, that is, after the process of step S5 of FIG. 6, the process proceeds to step S6, and it is determined whether the energy of the crocodile 31 is 0 or less. When it is determined in step S6 that the energy of the crocodile 31 is 0 or less, the process ends. That is, the game is over when the monster 32 (player B) wins.

When it is determined in step S6 that the energy of the crocodile 31 is not less than 0, the process proceeds to step S7, and the attack or replenishment of the crocodile 31 is performed.

That is, in step S7, first in steps S51 to S61 shown in FIG. 13, the monster 32 in step S31 to S41 (FIG. 12) described above is set to the crocodile 31, the crocodile 31 is set to the monster 32, and the battle button 23a. Is replaced with the battle button 24a or the energy button 23b is replaced with the energy button 24b.

Then, in step S62, it is determined whether or not the value of the time counter set in the variable TIM in step S55 is equal to, for example, the tens digit of the energy of the current monster 32.

If it is determined in step S62 that the value of the variable TIM is not equal to the current tenth digit of the monster 32, the process proceeds to step S63, and the energy of the monster 32 is calculated in step S58. From the score obtained, update according to the following formula (3
It is reduced by the attack of 1.) Energy of Monster 32 ← Energy of Monster 32-Score

In step S62, the variable TI
When it is determined that the value of M is equal to the number of tens of the current energy of the monster 32, the process proceeds to step S64.
The energy of the monster 32 is updated (decreased by the attack of the crocodile 31 against the monster 32) from the score calculated in step S58 according to the following equation, and the process proceeds to step S65. Energy of Monster 32 ← Energy of Monster 32-Score x 2

Therefore, the value of the variable TIM and the current monster 3
When the tens digit of the energy of 2 is equal, it is possible to do double damage to the monster 32 as compared with the case where it is not.

In step S63 or S64, the monster 32
Is updated (reduced by the attack of the crocodile 31 against the monster 32), the process proceeds to step S65, the energy of the monster 32 is displayed again on the display unit 18, and the process ends.

When the variable KF is 1, that is, when the crocodile 31 attacks the monster 32, the water flow is discharged from the mouth of the crocodile 31 (the water flow at the mouth of the crocodile 31). Is displayed).

After the processing of steps S51 to S65 of FIG. 13, that is, after the processing of step S7 of FIG. 6, the process proceeds to step S8, and it is determined whether the energy of the monster 32 is 0 or less. When it is determined in step S8 that the energy of the monster 32 is not 0 or less, the process returns to step S5,
The processing from step S5 is repeated again.

If it is determined in step S8 that the energy of the monster 32 is 0 or less, the process is terminated.
That is, the game is over when the crocodile 31 (player A) wins.

The game can be ended by operating the CD display button 22 (FIG. 2) during the game.

As described above, the CD of player A or B
Since the game data such as the energy and the attack power of the crocodile 31 or the monster 32 are set from the TOC in step 3,
It is possible to prevent the characteristics of 1 or the monster 32 from changing and distracting the users (players A and B) from the game.

Furthermore, when a predetermined condition (condition in step S42 (FIG. 12) or S62 (FIG. 13)) is satisfied, damage caused to the opponent by the monster 32 or the crocodile 31 is increased. Therefore, it is possible to attract the user's interest.

In the above-mentioned embodiment relating to the CD battle game, when the predetermined condition is satisfied, for example, the value of the variable TIM and the current energy of the crocodile 31 is 10
If the value of the zero digit multiplied by 0.5 is equal,
The monster 32 can now deal twice as much damage to the crocodile 31 as it would otherwise.
Not limited to this case, the damage that the monster 32 gives to the crocodile 31 can be increased or decreased.

Similarly, when the predetermined condition is satisfied,
For example, when the value of the variable TIM is equal to the tens digit of the current energy of the monster 32, the crocodile 31 can cause double damage to the monster 32 as compared to the case where it is not. I made it possible, but not limited to this case,
It is possible to increase or decrease the damage done by the crocodile 31 to the monster 32.

Furthermore, the attack power or energy of the crocodile 31 (monster 32) is calculated according to the equation (1) or (2), respectively. The calculation method is not limited to this. That is, from the TOC, as other information,
For example, the time of the shortest song recorded on the CD is taken out, and the crocodile 31 (monster 3
The attack power or energy of 2) can be calculated.

Next, when the music battle button 26 (FIG. 2) of the key input section 15 is operated, the mode of the device is set as the character of the player (self), for example, the crocodile 31 and the character of the enemy. , A music battle game mode where, for example, a monster 32 is played.

A music battle game is a device and 1
A game in which two players are competing, that is, when the player mounts the CD1 on the device, a monster army consisting of monsters corresponding to each song recorded on the CD1 (monsters corresponding to the number of songs recorded on CD1) is formed. In this game, you become an enemy and play against the crocodile 31 as a player character.

In this music battle game, after the player selects a monster to fight against from the monster corps, that is, a song, they attack each other alternately or replenish their own energy, so that the energy of the opponent is given first. Those who set 0 will win. Also, during the match, a song corresponding to the monster selected by the player is reproduced from CD1,
Meanwhile, if the player, that is, the crocodile 31 does not defeat the monster 32, the crocodile 31 loses. Then, the ultimate victory or defeat is decided by the monster 31 being defeated by the monster corps, for example, three times, or the crocodile 31 defeating the boss of the monster corps.

The attack power or energy supply amount of the crocodile 31 is determined by the volume level of the music (audio signal) reproduced from the CD 1, and therefore the player is reproduced from the CD 1. If the player attacks or replenishes energy in good timing based on the volume level of a song (audio signal), he or she can reinforce a strong attack or replenish sufficient energy.

In addition, the crocodile 31 as a player character is provided with crocodile of different types (described later), and the player matches the monster (the song recorded on the CD) in accordance with the crocodile. You can select the crocodile as your character from the inside.

Therefore, when the music battle game is played, it is first determined in step S71 of the flowchart shown in FIG. 14 whether or not the music battle button 26 (FIG. 2) of the key input unit 15 has been turned ON. When it is determined in step S71 that the music battle button 26 is not turned on, the process returns to step S71 again. When it is determined in step S71 that the music battle button 26 is turned on, a message is displayed on the display unit 18 to set the CD 1.

Then, the processing advances to step S72, at which the device C
It is determined whether D1 is set. Step S7
If it is determined in step 2 that CD1 is not set in the device, the process returns to step S72 again. Step S7
If it is determined in step 2 that the CD1 is set in the device, the process proceeds to step S73, and data such as energy of the monster corps as an enemy is initialized.

That is, in step S73, first, in step S81 of FIG. 16, the TO of the CD loaded in the apparatus is
C (FIG. 5) is read and temporarily stored in the TOC memory 14.

The TOC stored in the TOC memory 14 is
It is read out by the game control unit 11 via the CD control unit 12, where the start time of each song recorded on the CD 1 is extracted from the TOC.

That is, the value in the TOC is 00H to 9
Among points have become 9H (bit Q ₁₇ to Q ₂₄₎ (FIG. 5), is referred to different all points Q channel bits Q ₅₇ to Q ₈₀ of its value, the head of each song recorded on CD1 The absolute time (M minutes S seconds F frames) is retrieved.

Further, the absolute time at the beginning of the nth song is subtracted from the absolute time at the beginning of the (n + 1) th song (n = 1, 2,
..., N-1: N is the number of songs recorded on CD1, the recording time of each song ( _Mn minutes _Sn seconds _Fn frames) (more precisely,
At the true time of the song, the time including the time of the pause existing after the song) is calculated.

Then, the energy of the monster corresponding to the nth music piece is calculated from the frame number F of the absolute time (M minutes S seconds F frames) at the beginning of the music piece according to the following equation. Monster energy corresponding to the nth song ← 40 × F

After the energy of the monster corresponding to the N songs recorded on the CD1 is calculated as described above, the process proceeds to step S83, and the boss of the monster corps (hereinafter referred to as the boss monster) is determined. .

As described above, in the music battle game, if the boss monster of the monster corps is defeated, the player (crocodile 31) wins. However, the boss monster is described below. It has a lot of energy and is hard to knock down.

That is, in step S83, the recording time (M _n minutes S _n seconds F of each music piece calculated in step S82 is calculated.
_The number of frames F _n of ( _n frames) is multiplied by the random number generated by the random number generation circuit 16. Then, the song having the maximum value is detected, and the monster corresponding to the song is set as the boss monster.

Then, the process proceeds to step S84, the energy of the boss monster is calculated according to the following equation, and step S8
Go to 5. Boss monster energy ← 5 x Boss monster energy

In step S85, the monster corresponding to the song 5 songs before the song of the boss monster and the monster corresponding to the song 5 songs after are set as bonus monsters (described later), and the data table of the monster corps (see FIG. 17). ) Is created.

That is, for example, as shown in FIG. 17, the song number (what song), the energy of the monster corresponding to the song set in step S82 (if the monster is a boss monster, step (Energy set in S83), a boss flag indicating whether or not the monster is a boss monster (if the monster is a boss monster, it is set to 1 out of 0 and 1, for example, otherwise 0 Of 1 and 1, for example, is set to 0), and a bonus flag indicating whether or not the monster is a bonus monster (if the monster is a bonus monster, it is set to, for example, 1 of 0 and 1, If not, it is set to 0 of 1 and 0, for example), and a life-and-death flag indicating whether or not the monster has been defeated by the crocodile 31 (0 if not yet defeated). And of 1 Chino, for example set to 1, if they are already defeated is of 0 and 1, the data table is created made of, for example, 0 is set to).

In step S85, the created data table is stored in the game data memory 17, and the process ends.

After the processing of steps S81 to S85 of FIG. 16, that is, after the processing of step S73 of FIG.
Proceeding to 74, the match between Alligator 31 and the Monster Army begins.

That is, in step S74, first, in step S91 of FIG. 18, a variable WN for counting the number of times the crocodile 31 was defeated by the monster corps is set to 1 as an initial value, and the process proceeds to step S92. The crocodile 31 as a character operated by the player is selected.

That is, in step S92, first in step S121 of FIG.
A screen for selecting the crocodile 31 as shown in 5 appears,
It proceeds to step S122.

Here, the music battle button 26
Each time (FIG. 2) is operated, step S71 is performed.
(FIG. 14) The crocodile 31 (FIG. 1) displayed on the display unit 18 is displayed.
The color of 5) is alternately switched to, for example, yellow or pink. Further, the characteristics of the yellow crocodile 31 and the pink crocodile 31 are different as described later.

When the battle button 24a (FIG. 2) is operated in step S122, the color crocodile 31 displayed at that time is selected as the player's character, and the process proceeds to step S123, where the energy of the crocodile 31 is selected. To
For example, 1200 is set as the initial value, and the process ends.

After the processing of steps S121 to S123,
That is, after the processing of step S92 of FIG. 18, step S93
Then, the variable BN, which will be described later, is set to 1 as an initial value, and the process proceeds to step S94.

In step S94, the monster 32 that fights against the crocodile 31 is selected from the monster corps.

That is, in step S94, first in step S131 of FIG. 20, step S85 (FIG. 16).
The data table (FIG. 17) of the monster corps created in 1 is referred to, and the monster symbol (FIG. 21) corresponding to the song is displayed on the display unit 18.

That is, when, for example, 10 pieces of music are recorded on the CD 1, at step S131, as shown in FIG.
As shown in FIG. 1, ten monster symbols are displayed, and the process proceeds to step S132. Of the monster symbols,
The symbol of the boss monster (the shaded symbol in FIG. 21) is displayed in a color different from that of the monster that is not, for example, red. Also, the bonus monster is not known to the player.

Here, each time the battle button 23a (FIG. 2) is operated, the symbol 1 of the monster on the upper left is changed to symbols 2, 3, ... Has become. Also, the energy button 23b
When (Fig. 2) is operated, the symbols of monsters are sequentially displayed in blue in the direction opposite to that when the battle button 23a is operated.

In step S132, when the battle button 24a (FIG. 2) is operated, the monster 32 displayed in blue at that time is selected as the opponent of the crocodile 31 and the process ends.

After the processing of steps S131 to S132,
That is, after the processing of step S94 in FIG. 18, step S95
22, the battle screen between the crocodile 31 and the monster 32 as shown in FIG. 22 is displayed on the display unit 18.

That is, in step S95, the monster 32
With crocodile 31 symbol EG showing energy
To the left or right of, the energy of the monster 32, or crocodile 3
For example, 3800 or 1200 as the energy of 1
Are displayed respectively, and the process proceeds to step S96.

In step S96, of the songs recorded on the CD 1, reproduction of the song corresponding to the monster 32 selected in step S94 is started. That is, the music recorded on the CD 1 is reproduced and output from the speaker 9 in the same manner as in the CD reproduction mode described above.

At the same time, the reproduced song (audio signal)
Is input to the volume level detection unit 10, and the level is detected there.

In this case, a flame corresponding to the level of the audio signal detected by the volume level detecting section 10 is discharged from the mouth of the monster 32,
As a result, the level of the song (audio signal) can be visually recognized.

Then, in step S97, the crocodile 31
It is determined whether or not the (player-side character) has operated the battle button 24a (FIG. 2) for attacking the monster 32 (enemy character). In step S97,
When it is determined that the battle button 24a is not operated, the process proceeds to step S98, and it is determined whether or not the energy button 24b (FIG. 2) for supplying the energy of the crocodile 31 is operated.

If it is determined in step S98 that the energy button 24b is not operated, the process returns to step S97, it is determined that the battle button 24a is operated in step S97, or the energy button 24b is operated in step S98. The processes of steps S97 and S98 are repeated until it is determined that they have been performed.

At step S97, the battle button 2
If it is determined that 4a is operated, the process proceeds to step S99, and in order to store that the battle button 24a is operated, in order to store the variable KF, for example, 1 out of 0 and 1 is set.
Is set, and the process proceeds to step S101.

On the other hand, if it is determined in step S98 that the energy button 24b has been operated, then the flow proceeds to step S100, and in order to store that the energy button 24b has been operated, it is stored in the variable KF among 0 and 1. , For example, 0 is set, and the process proceeds to step S101.

In step S101, step S9
7 or S98, when the battle button 24a or the energy button 24b is operated, the volume level detection unit 10
The score is calculated from the volume level detected in (the level of the audio signal reproduced from the CD1).

Here, in step S92 (steps S121 to S123 (FIG. 19)) described above, the yellow crocodile 31
When is selected, the score of alligator 31 is calculated according to the following equation, for example. Score ← a × (volume level−average volume level) (3) where a is a positive constant.

Therefore, in this case, if the battle button 24a or the energy button 24b is operated while the level (volume level) of the audio signal reproduced from the CD 1 is high, the score becomes high.

Also, in step S92 (steps S121 to S123 (FIG. 19)) described above, the pink crocodile 3
When 1 is selected, the score of alligator 31 is calculated according to the following equation, for example. Score = a x (average volume level-volume level) (4)

Therefore, in this case, if the battle button 24a or the energy button 24b is operated when the level (volume level) of the audio signal reproduced from the CD 1 is low, the score becomes high.

After the score is calculated in step S101,
In step S102, the attack of the crocodile 31 or replenishment of energy is performed.

That is, in step S102, first, referring to FIG.
In step S141 of FIG.
It is determined whether the score calculated in 8) is a positive number. When it is determined in step S141 that the score is not a positive number, the process proceeds to step S150, and the score is set to 0. Then, in the lower part of the display unit 18 where the energy of the crocodile 31 is displayed, the score of the crocodile 31 is 0.
Is displayed (FIG. 22, and in FIG. 22, alligator 3
300 is displayed as the score of 1), and the process ends.

If it is determined in step S141 that the score is a positive number, the process proceeds to step S142, the score is multiplied by the variable BN, and the score is held as the alligator score. Then, the process proceeds to step S143, and step S14
The crocodile score calculated in 2 is displayed on the lower portion of the display unit 18 at the position where the energy of the crocodile 31 is displayed (see FIG. 2).
22. In addition, in FIG. 22, the score of alligator 31 is 3
00 is displayed), the process proceeds to step S145.

In step S145, the variable KF is 1
Is determined. When it is determined in step S145 that the variable KF is not 1, that is, the crocodile 3
When the energy button 24b for replenishing one's own energy is operated by the user 1, the process proceeds to step S148,
The energy of the crocodile 31 is updated (supplemented) from the crocodile score calculated in step S142 according to the following equation, and the process proceeds to step S149. Energy of crocodile 31 ← Energy of crocodile 31 + crocodile score

In step S149, step S1
The energy of the crocodile 31 replenished at 48 is displayed again on the display unit 18, and the process ends.

On the other hand, in step S145, the variable K
If F is determined to be 1, that is, alligator 31 is monster 3
When the battle button 24a for attacking 2 is operated, the process proceeds to step S146, and the energy of the monster 32 is
The crocodile score calculated in step S142 is updated (decreased by the attack of the crocodile 31 against the monster 32) according to the following equation. Energy of monster 32 ← Energy of monster 32-Croc

In step S147, step S1
The energy of the monster 32 reduced by the attack of the crocodile 31 at 46 is displayed again on the display unit 18, and the process ends.

Therefore, when the crocodile 31 attacks the monster 32, the higher the score (larger), the more damage is done to the monster 32. Also, when the crocodile 31 replenishes its own energy, the score is high (large)
The more energy is replenished.

As described above, after the attack or energy supply of the crocodile 31 is performed by the processing of steps S141 to 150, that is, the processing of step S102 of FIG. 18, the process proceeds to step S103, and the energy of the monster 32 is 0 or less. It is determined whether or not there is. When it is determined in step S103 that the energy of the monster 32 is 0 or less, that is, when the crocodile 31 defeats the monster 32, the process proceeds to step S104, and the data table stored in the game data memory 17 (FIG. 17). Is referred to, and it is determined whether or not the monster 32 is a boss monster.

When it is determined in step S104 that the monster 32 is the boss monster, it is determined that the crocodile 31 (player) has won the monster army, and the process ends.

If it is determined in step S104 that the monster 32 is not the boss monster, step S105
Then, for example, 1200 is added to the energy of the crocodile 31, that is, the energy of the crocodile 31 is increased by 1200, and the process proceeds to step S106.

In step S106, the data table (FIG. 17) stored in the game data memory 17 is referred to, and it is determined whether or not the monster 32 defeated by the crocodile 31 is a bonus monster.

In step S106, if it is determined that the monster 32 defeated by the crocodile 31 is not a bonus monster, step S107 is skipped and step S94 is executed.
Then, the processing from step S94 is repeated again.

When it is determined in step S106 that the monster 32 which the crocodile 31 has defeated is a bonus monster, the process proceeds to step S107, and the variable BN is incremented by one.

That is, when the monster 32 which the crocodile 31 has defeated is a bonus monster, the variable BN is increased. Therefore,
As described above, the variable BN is set in step S142 (FIG. 2).
Since it is multiplied by the score in 3), the attack power of the crocodile 31 (damage that can be given to the monster 32) and the defense power (supply amount of energy) will be used in the subsequent battle with the monster corps. Will be up. In this case, a bonus mark (not shown) is displayed on the display unit 18 so that the crocodile 31 can know that the bonus monster has been defeated.

After the variable BN is incremented by 1 in step S107, the process returns to step S94 and the processing from step S94 is repeated. In this case, the symbol of the defeated monster is not displayed on the screen (FIG. 21) for selecting the monster as the opponent in step S94.

On the other hand, in step S103, the monster 3
When it is determined that the energy of 2 is not less than 0, the process proceeds to step S108, and a wait time (waiting time) of, for example, 1 to 2 seconds is set, and the process proceeds to step S109.

In step S109, the monster 32 is attacked or energy is replenished.

That is, in step S109, first, referring to FIG.
In step S161 of FIG.
It is determined whether the score calculated in 8) is 0 or more.

Here, when the monster 31 attacks or replenishes energy, when the score calculated in step S101 is not 0 or more, that is, when the score is a negative number, the score is the attack power or energy of the monster 31. It is used as it is as the score of the monster 31 to determine the supply amount of. Also,
When the score calculated in step S101 is 0 or more, the random number generated by the random number generation circuit 16 is used to determine the attack power of the monster 31 or the amount of energy supply.
It is used as a score of 1.

In step S161, step S1
When it is determined that the score calculated in 01 (FIG. 18) is not 0 or more, step S162 is skipped and the process proceeds to step S163.

In step S161, step S1
When it is determined that the score calculated in 01 (FIG. 18) is 0 or more, the process proceeds to step S162, and the game control unit 1
A clock is supplied from 1 to the random number generation circuit 16, a random number is output from the random number generation circuit 16, and the process proceeds to step S163.

Here, in this case, the random number generation circuit 16
Negative random numbers are generated from.

In step S163, the score is displayed below the position where the energy of the monster 32 is displayed on the display unit 18 (FIG. 22, it should be noted that 200 is displayed as the score of the monster 32 in FIG. 22). ), And proceeds to step S164.

In this case, the score of the monster 32 is a negative number, but the negative sign (-) is deleted from the display portion 18 so as to be displayed.

In step S164, the variable KF is 1
Is determined. If it is determined in step S164 that the variable KF is not 1, that is, if the crocodile 31 replenishes its own energy in step S102 (FIG. 18), the monster 32 also replenishes its own energy.

That is, in this case, the process proceeds to step S165, and the energy of the monster 32 is updated (supplied) from the score according to the following equation. Energy of Monster 32 ← Energy of Monster 32-Score

In this case, since the score is a negative number as described above, the energy of the monster 32 increases according to the above equation.

Then, the process proceeds to step S166, the energy of the monster 32 replenished in step S165 is displayed again on the display unit 18, and the process ends.

On the other hand, in step S164, the variable K
When F is determined to be 1, that is, step S102
In FIG. 18, when the crocodile 31 attacks the monster 32, the monster 32 also attacks the crocodile 31.

That is, in this case, the process proceeds to step S167, and the energy of the crocodile 31 is updated from the score according to the following equation (decreased by the attack of the monster 32 on the crocodile 31):
To be done. Energy of alligator 31 ← Energy of alligator 31 + points

In this case, since the score is a negative number as described above, the energy of the crocodile 31 is reduced by the above equation.

Then, in step S168, the crocodile 31 which has been reduced by the attack of the monster 32 in step S167 is used.
Energy is displayed again on the display unit 18, and the process ends.

As described above, after the monster 32 is attacked or the energy is replenished by the processing of steps S161 to 168, that is, the processing of step S109 of FIG. 18, the process proceeds to step S110, and the energy of the crocodile 31 is 0 or less. It is determined whether or not there is. When it is determined in step S110 that the energy of the crocodile 31 is not 0 or less, the process proceeds to step S111, and it is determined whether or not the reproduction of the song started in step S96 is completed. Step S111
If it is determined that the reproduction of the music has not ended, the process returns to step S97 and the process from step S97 is repeated.

If it is determined in step S111 that the reproduction of the music has ended, it is determined that the crocodile 31 cannot defeat the monster 32, and the crocodile 31 (player) is defeated, and the process proceeds to step S112.

On the other hand, in step S110, alligator 3
When it is determined that the energy of 1 is 0 or less, that is, when the crocodile 31 is defeated by the monster 32, step S111 is skipped, the process proceeds to step S112, and it is determined whether the variable WN is 3 or not. It

In step S112, the variable WN is 3
If not, that is, the crocodile 31 becomes the monster 32,
If it has not been defeated three times, the process proceeds to step S113, the variable WN is incremented by 1, and the step S113 is performed.
Returning to 92, the processing from step S92 is repeated again.

In step S112, the variable WN is 3
If it is determined that, that is, the crocodile 31 becomes the monster 32,
