40 (V) (non-interlace), 38 in mode 9
4 (H) × 480 (V) (interlace). That is, the display start position and the display end position can be specified independently in the horizontal and vertical directions. The relationship between the value that can be specified for each coordinate and the screen mode is, for example, the horizontal coordinate specification range is 0 to 276 (horizontal display start position coordinate) and 4 to 280 (horizontal display) in modes 0 and 4. In the modes 8 and 9, 0 to 396 (horizontal display start position coordinates) and 4 to 400 (vertical display end position coordinates). The designated range of vertical coordinates is 0 to 240 (vertical display start position coordinates) in modes 0 to 3 and 8, and 4 to 484 (vertical display end position coordinates) in modes 4 to 7 and 9. . here,
The horizontal start and end position coordinates need to be set to be a multiple of four. Therefore, the minimum screen size is
Pixels, 2 pixels vertically (at non-interlace) or 4 pixels (at interlace).

The GPU 62 has a 16-bit direct mode (32768) as a mode relating to the number of display colors.
Color) and 24-bit direct mode (full color). The 16-bit direct mode (hereinafter referred to as 16-bit mode) is a 32768-color display mode. In the 16-bit mode, a 24-bit direct mode (hereinafter referred to as a 24-bit mode)
Although the number of display colors is limited as compared with the above, the color calculation inside the GPU 62 at the time of drawing is performed in 24 bits, and a so-called dither function capable of increasing the gradation in a pseudo manner is provided. (24-bit color) display is possible. The 24-bit mode is 2677
This is a mode for displaying 7216 colors (full color). However,
Only the display of the image data transferred in the frame buffer 63 (display of the bitmap) is possible, and the GPU 62
Cannot execute the drawing function. Here, the bit length of one pixel is 24 bits, but the values of the coordinates and display position on the frame buffer 63 need to be specified on the basis of 16 bits. That is, 24 of 640 × 480
The bit image data is 96 bits in the frame buffer 63.
It is treated as 0x480. Also, the horizontal display end position coordinates need to be set to be a multiple of 8, so that the minimum screen size in this 24-bit mode is 8 × 2 pixels.

The GPU 62 has the following drawing function. First, 1 × 1 dot to 256 × 25
For a 6-dot polygon or sprite, a 4-bit CLUT (4-bit mode, 16 colors / polygon, sprite), an 8-bit CLUT (8-bit mode, 256 colors / polygon, sprite), or a 16-bit CLUT (16
Bit mode, 32768 colors / polygon, sprite)
Polygon or sprite drawing function that can draw etc.,
Draw by specifying the coordinates on the screen of each vertex of polygons and sprites, flat shading to fill the inside of polygons and sprites with the same color, Gouraud shading to specify different colors for each vertex and gradation inside, polygon A polygon drawing function for preparing a texture pattern that is two-dimensional image data (particularly, a sprite pattern is called a sprite pattern) on the surface of a sprite, and performing a texture mapping and the like, a straight line drawing function capable of gradation, and a CP.
The image transfer function such as transfer from the U51 to the frame buffer 63 and the other function of translucent by taking the average of each pixel, that is, by mixing the pixel data of each pixel at a predetermined ratio α There is a function called a blending function, a dither function that blurs by putting noise on a color boundary, a drawing clipping function that does not display a portion beyond the drawing area, an offset designation function that moves the drawing origin according to the drawing area, and the like.

The coordinate system for drawing is 11 with a sign.
The unit of bit is -1024 to ++ for each of X and Y.
Take the value of 1023. In addition, since the size of the frame buffer 63 in this example is 1024 × 512, the protruding portion is folded back. The origin of the drawing coordinates can be freely changed in the frame buffer 63 by the function of arbitrarily setting the offset value of the coordinate values. In addition, drawing is performed by the drawing clipping function.
This is performed only for an arbitrary rectangular area in the frame buffer 63. Further, the CPU 62 supports a texture of a maximum of 256 × 256 dots, and can freely set vertical and horizontal values.

The image data (texture pattern or sprite pattern) to be attached to the polygon or sprite is arranged in a non-display area of the frame buffer 63. The texture pattern or sprite pattern can be placed on the frame buffer 63 as many as the memory permits, and 256 × 256 pixels are defined as one page, and this 256 × 256 area is called a texture page. The location of one texture page is determined by specifying a page number as a parameter for specifying the position (address) of the texture page in the drawing command.

For a texture pattern or a sprite pattern, a 4-bit CLUT (4-bit mode), an 8-bit CLUT (8-bit mode), and a 16-bit CLUT
(16-bit mode). In the 4-bit and 8-bit CLUT color modes, C
Use LUT. The CLUT has 16 to 256 R, G, and B values of three primary colors representing colors to be finally displayed, arranged in the frame buffer 63. Each R, G, B
The values are numbered sequentially from the left on the frame buffer 63, and the texture pattern or sprite pattern represents the color of each pixel by this number. Also,
CLUT can be selected in units of polygons or sprites, independent CLUTs for all polygons or sprites
It is also possible to have The storage position of the CLUT in the frame buffer 63 is determined by the parameter used to specify the position (address) of the CLUT in the drawing command.
It is determined by specifying the coordinates of the left end of the LUT.

The GPU 62 uses a method called frame double buffering as a moving image display method. This frame double buffering is to prepare two rectangular areas on the frame buffer 63, display the other side while drawing in one area, and exchange the two areas with each other when drawing is completed. It is. Thus, it is possible to avoid displaying the state of rewriting. Note that the buffer switching operation is performed during the vertical blanking period. In the GPU 62, since the rectangular area to be drawn and the origin of the coordinate system can be freely set, a plurality of buffers can be realized by moving the two.

The drawing command is in a packet format. In this example, the drawing command is in a format directly specified by the CPU 51.
There is a format specified directly by dedicated hardware. Especially,
In the format that the dedicated hardware directly specifies, the CPU 5
A packet configuration is used in which a tag is added to the instruction format used by 1 in which the number of words of the instruction and a pointer to the next instruction are added. As a result, a plurality of instruction sequences that are not placed in a continuous area on the frame buffer 63 can be connected and executed at once. In this case, the transfer of the drawing command is performed by dedicated hardware, and the CPU 51 is not involved at all.

The parameters that can be included in the drawing command are as follows.

CDDE: command code call option R, G, B: luminance value shared by all vertices Rn, Bn, Gn: luminance value of vertex n Xn, Yn: two-dimensional coordinates Un of vertex n in drawing space Un, Vn: two-dimensional coordinates of a point on the texture source space corresponding to vertex n CBA (CULT BASE ADDRESS): CL
UT start address TSB (TEXTURE SOURCE BASE):
Additional information such as texture page top address and texture type For example, triangle drawing command (command code 1h)
Gives vertex information as a command argument after a command code containing options. Arguments and formats differ depending on the option.

As parameters, IIP: type of luminance value SIZ: size of rectangular area CNT: vertex to be used TME: presence or absence of texture mapping ABE: presence or absence of translucent processing TGE: presence or absence of multiplication of the texture pattern and the luminance value For example When IIP is 0, one type of luminance value (R, G,
In B), a triangle is drawn (flat shading).
For example, when CNT is 0, one triangle is drawn at three vertices following the command, and when CNT is 1, a connected triangle is drawn at four vertices following the command, that is, a quadrangle is drawn.
When TME is 0, texture mapping is turned off and 1
When, texture mapping is turned on. ABE is 0
When the value is 1, the translucent process is off, and when the value is 1, the translucent process is on. TGE is effective only in the case of TME. When TGE is 0, the texture pattern is multiplied by the luminance value for display. When TGE is 1, only the texture pattern is drawn.

Line drawing command (command code = 2)
h) gives single point information as a command argument after a command code including an option. The number and format of arguments differ depending on the option. For example, when the IIP is 0, the pixel is drawn with the designated brightness value, and when the IIP is 1, the brightness values of the two vertices are linearly interpolated with the displacement in the long axis direction of the line segment. When CNT is 0, one straight line is drawn at the two end points following the command, and when CNT is 1, a connected straight line is drawn. When ABE is 0, the translucent processing is off, and when ABE is 1, the translucent processing is on. When drawing a connected straight line, an end code indicating the end of the command is required at the end.

In the sprite drawing command (command code = 3h), after the command code (including an option), luminance information, the lower left point of the rectangular area, the upper left point of the texture source space, and the width and height of the rectangular area are command arguments. Give as. The number and format of arguments differ depending on the option. Since the sprite drawing command processes two pixels at the same time, the two-dimensional coordinates Un of the point on the texture source space corresponding to the vertex n must be specified as an even number.

That is, the lower one bit has no meaning.
When TME is 0, texture mapping is turned off, and when TME is 1, texture mapping is turned on. AB
When E is 0, the translucent process is turned off, and when E is 1, the translucent process is turned on. TGE (valid only for TME) is 0
In the case of, drawing is performed by multiplying a texture pattern (in this case, a sprite pattern) by a constant luminance value. In the case of 1, only the texture pattern is drawn. SIZ is 00
Is specified by H and 2 fields, and 01 is specified by 1
In the case of × 1, 10, the size is specified as 8 × 8, and in the case of 11, the size is specified as 16 × 16.

Next, the data stored in the ROM 54 and
A game program (pachinko game program) loaded from the CD-ROM 84 onto the main memory 53 according to the operation system program and executed by the CPU 51 according to the operation system program, and is stored on the main memory 53 by the pachinko game program. Table to be developed (nail coordinate table and ball management table), and
Video output means 65 according to the pachinko game program
An example of an image displayed on the display device via the PC will be described.

FIG. 3 shows the state of the CPU 5 stored in the ROM 54.
1 is a flowchart showing an outline of an operation system program executed by the first embodiment. This operation system is started by turning on the power to the apparatus main body. Then, in the first S001 after the star, the program data (game program,
Data) is read and written to the main memory 53.

In the next S002, the game program read out in S001 is replaced by a CPU 51 which is a computer.
Is executed by This operation system continues to be executed until the power supplied to the apparatus main body is cut off.

FIGS. 3 to 9 are flowcharts showing the contents of the pachinko game program which is the game program executed in S002 of FIG. In the first step S101 after entering the processing of FIG. 4, which is the main routine of the pachinko game program, it is continuously checked whether or not the start button 92b has been pressed.

In S102 executed when the start button 92b is pressed, the select screen 10 shown in FIG.
5 is displayed on the display device via the video output means 65. The select screen 105 displays one of four game modes included in the pachinko game, that is, one of the following modes: “study research” mode, “pounding test” mode, “winning / losing notebook” mode, and “pachinko term dictionary” mode. This is a screen for selecting a mode, and displays icons corresponding to each game mode.

In the next step S103, an initial mode (for example, a "click and play" mode) is selected as a play target mode. Then, the icon corresponding to the selected play target mode is displayed brighter than the other icons.

In the next step S104, it is checked whether or not the cross key (any of L, R, U and D) of the controller 92 has been pressed. And when pressed,
The process proceeds from S104 to S105. This S10
In 5, when the pressing direction of the cross key is on the right side,
The next game mode is selected as the play target mode, and if the direction in which the cross key is pressed is on the left side, the previous game mode is selected as the play target mode. When S105 is completed, the process returns to S104.

On the other hand, if it is determined in step S104 that the cross key has not been pressed, it is checked in step S106 whether the fourth button 92f has been pressed. If the fourth button 92f has not been pressed, the process returns to S104.

On the other hand, the fourth button 9
If it is determined that 2f has been pressed, the next step S107
In, the game mode currently selected as the play target mode is determined, and the corresponding program data is read from the CD-ROM 84 to the main memory 53.

In the next S108, flags, variables, and tables necessary for executing the game mode determined in S107 are set.

In each of the above-mentioned "click-and-play" mode and "pounding test" mode, the pachinko board is displayed on the display device via the video output means 65, and the ball in the displayed pachinko board is displayed. This is a game mode in which the trajectory is calculated and the display of the ball is moved along the trajectory.

FIG. 12 is an image of the pachinko board displayed on the display device in these game modes. As shown in FIG. 12, the pachinko board surface has a rail R arranged in a substantially spiral shape so as to form a ball launch path G, and a roulette 31 arranged substantially in the center of a game area surrounded by the rail R. , An out opening 32 arranged at the lowest position of the game area, a winning opening 30 studded in the game area, and nails 33a, 33b. In order to calculate the trajectory of the ball on the pachinko board, the position of the ball on the pachinko board and the positions of the nails 33a and 33b and the outer wall of the roulette 31 which are obstacles to the ball are accurately determined. Must be specified.

Further, in order to three-dimensionally display the state of the nails 33a and 33b on the pachinko board surface from various angles, position data of each part of the nails 33a and 33b (root position data and head position data) 3D display based on the position data).

Therefore, the data for displaying the pachinko board surface shown in FIG. 12 is such that the horizontal direction in FIG. 12 is the X coordinate (left is the + direction) and the vertical direction is the Y coordinate (the bottom is the + direction). It is created as map data on the XY coordinates, the position of each ball is defined as a coordinate point on the XY coordinates, and the position of each nail 33a, 33b is
-The coordinate points corresponding to the position of the root on the Y coordinate and the coordinate points corresponding to the position of the head are separately defined.

Therefore, when the above-mentioned "click-and-click" mode and the "puzzle test" mode are selected as the game object modes, the nail coordinate table (S108) for defining the coordinate position of each part protruding from the pachinko board surface in S108. FIG. 10) and a ball management table (FIG. 11) for defining the coordinate position of the ball are developed on the main memory 53.

The nail coordinate table (corresponding to nail coordinate defining means) shown in FIG. 10 is provided for each nail 33 arranged on the pachinko board.
For each of a and 33b, the nail ID (N) and the nail axis intermediate coordinates (KX _N , KY _N ) indicating the axial center position at the intermediate portion (the portion where the ball hits) of the nail axis (the intermediate portion of the nail) Coordinate position), reference coordinates (X _N , Y _N ) indicating the axial position at the base of the nail (corresponding to the coordinate position at the base of the nail), and nail head coordinates indicating the axial position at the head of the nail (HX _N , HY _N )
(Corresponding to the coordinate position of the nail head) and the nail axis intermediate coordinates (KX _N , KY _N ) with respect to the reference coordinates (X _N , Y _N ) of the nail
The adjustment amount (DX _N , DY _N ) indicating the shift amount is defined. The nails corresponding to the nail IDs (N) = 0 to 9 are the adjustable nails 33b capable of moving the nail axis intermediate coordinates (KX _N , KY _N ) (adjusting the nails). Axis intermediate coordinates (KX _N , KY _N ), nail point coordinates (HX _N , H
Y _N ) and the adjustment amounts (DX _N , DY _N ) can be rewritten (in the initial state, the nail axis intermediate coordinates (KX
_N , KY _N ) and the nail point coordinates (HX _N , HY _N ) have the same values as the reference coordinates (X _N , Y _N ), and the adjustment amounts (DX _N , D
Y _N ) is 0. ). Also, nail ID (N) = 1
Since the nails corresponding to 0 to 99 are non-adjustable nails 33a that cannot be adjusted, the nail axis intermediate coordinates (KX _N , KY _N ), the reference coordinates (X _N , Y _N ), and the nail head coordinates ( HX _N , HY _N ) cannot be rewritten, and the adjustment amount (DX _N , DY _N ) is not specified. Also, obstacles other than the nails 33a and 33b (for example, the outer wall of the roulette 31 and the side wall and the bottom of the winning opening 30).
Is regarded as a row of continuous nails (virtual nails), and the coordinate data of the virtual nails is defined in entries of ID (N) = 100 to 999. However, since the coordinate data of the virtual nail is used only for calculating the trajectory of the ball, the nail axis intermediate coordinates (K
X _N , KY _N ) are specified.

On the other hand, the ball management table shown in FIG. 11 stores the ID of each ball hit into the pachinko board.
(I), the ball center coordinates (T
X _N, TY _N) and ball velocity vector (VX _N indicating the velocity vector of the ball, defines the VY _N). Since the range of the ball ID (i) in this ball management table is 1 to 20,
Twenty balls can be simultaneously displayed and moved on the pachinko board.

In the next step S109 in FIG.
It is checked whether or not the play target mode determined in the above is a nail-adjustable game mode (that is, a “click-and-click study” mode). If the game mode is not the nail adjustable game mode, the process proceeds to S115. This S115
Then, the program data read in S107 is executed, and mode play is performed in the play target mode. In the next S116, it is checked whether or not the game end is selected during the mode play in S115. If the game end is not selected, the process returns to S115.
If the game end has been selected, the process returns to S102.

On the other hand, if it is determined in S109 that the play target mode determined in S107 is a game mode in which nail adjustment is possible (that is, a "click and play" mode), then in S110, the menu shown in FIG. Screen 11
0 is displayed on the display device. The menu screen 110 includes a “nail adjustment” icon 111 for reading the “nail adjustment” subroutine, and a “slingshot play” icon 1 for reading the “pachinko play” subroutine.
12 is a screen for displaying No. 12.

In the next step S111, when the cross key and the third button 92e of the controller 92 are simultaneously pressed, the "nail adjustment" icon 111 is displayed on the menu screen 110.
It is checked whether the fourth button 92f has been pressed in a state where is selected. Then, the “nail adjustment” icon 11
If the fourth button 92f is pressed in a state where 1 is selected, a "nail adjustment" subroutine as a nail coordinate moving means is executed in S112.

FIG. 4 is a flowchart showing the contents of the "nail adjustment" subroutine. In the first step S201 after entering this subroutine, the variables DX _N , DY _N , HX _N , and HY _N used for calculating the nail adjustment amount are initialized. In the next S202, 0 is substituted for a variable N indicating the nail ID of the nail to be adjusted.

In the next step S203, the main memory 53
Each nail read from the nail coordinate table (adjustable nail 33
b, based on the coordinate data of the non-adjustable nail 33a), FIG.
As shown in FIG. 5, the state of each nail 33a, 33b is shown in a three-dimensional table.
(Corresponding to display means). At this time, the value of the variable N

3B shows an image.

In the next step S204, it is checked whether or not the cross key of the controller 92 has been pressed. If the cross key is pressed, the process proceeds to S20.
Proceed to 5. In S205, the variable N is incremented if the pressing direction of the cross key is right, and the variable N is decremented if the pressing direction is left. Since the value that the variable N can take is in the range of 0 to 9, N = 0 when incrementing from N = 9, and N = 9 when decrementing from N = 0. When S205 is completed, the process returns to S203.

On the other hand, if it is determined in step S204 that the cross key has not been pressed, it is checked in step S206 whether the cross key and the third button 92e have been pressed simultaneously. If the cross key or the third button 92e has not been pressed, the process proceeds directly to S214 without performing nail adjustment.

On the other hand, if it is determined in S206 that the cross key and the third button 92e have been pressed simultaneously, the process proceeds to S207 in which the time during which the cross key and the third button 92e have been pressed simultaneously, and Based on the pressing direction of the cross key at that time (that is, input information from the operator),
An adjustment amount (X-direction adjustment amount, Y-direction adjustment amount) is calculated. Then, even if the nail to be adjusted is tilted according to the adjustment amount calculated in this manner, the width (ball diameter of the ball) that the ball can pass between the shaft middle part of this nail to be adjusted and the shaft middle part of another nail More width)
Check if the gap can be secured. Then, when a gap having a width (width equal to or larger than the diameter of the ball) through which the ball can pass cannot be secured, in S213, a comment stating “No more.
The process proceeds to S214.

On the other hand, if it is determined in S207 that a gap having a width through which the ball can pass can be ensured, the process proceeds to S208.
In, it is checked whether the adjustment amount calculated in S207 is within a predetermined limit. If the adjustment amount exceeds the limit, in S213, a comment stating "No more ... no turn" is displayed on the display device, and the process proceeds to S214.

[0084] On the contrary, when the adjustment amount is determined to be within the limits in S208, in S209, by substituting the X-direction adjustment amount calculated in S207 to the variable DX _N showing the X-direction adjustment amount , The variable DY _N indicating the Y-direction adjustment amount is S
The Y-direction adjustment amount calculated in 207 is substituted.

In the next step S210, the values of X _N and Y _{N in} the entry using the value of the variable N as the nail ID are read from the nail coordinate table in the main memory 53.

In the next S211, the following equation (1) is executed based on the value of X _{N and} the value of the variable DX _N read in S210, and the calculation result is substituted for the variable HX _N.

[0087]

HX _N = X _N + DX _N × 2 (1) Similarly, the following equation (2) is executed and calculated based on the value of Y _{N and} the value of the variable DY _N read in S210. The result is assigned to a variable HY _N.

[0088]

HY _N = Y _N + DY _N × 2 (2) In the next step S212, the entry of the nail ID that matches the variable N in the nail coordinate table in the main memory 53 includes the variables DX _N , DY Write the values of _N , HX _N and HY _N. S2
When 12 is completed, the process proceeds to S214.

In S214, it is checked whether the fourth button 92f has been pressed. If the fourth button 92f has not been pressed yet, the process proceeds to S215.
Proceed to In S215, the cross key and the first button 92c
Check if and were pressed at the same time. If the cross key and the first button 92c are pressed at the same time, the viewpoint of the screen displayed on the display device is changed in S216. For example, based on the image in FIG. 15, the viewpoint is made closer as shown in the image shown in FIG. 16, or the viewpoint is shifted in an oblique direction as shown in the image shown in FIG. 17. When S216 is completed, the process returns to S203 in order to display an image corresponding to the moved viewpoint. On the other hand, in S215, the cross key or the first button 92 is pressed.
If it is determined that c has not been pressed, the process returns directly to S203.

On the other hand, if it is determined in S214 that the fourth button 92f has been pressed, the "nail adjustment" subroutine ends, and the process returns to the main routine of FIG.
In the main routine of FIG. 3, after the completion of S112, the process returns to S111.

On the other hand, if it is determined in step S111 that the fourth button 92f has not been pressed while the "nail adjustment" icon is selected, then in step S113, the cross key and the third button 92e are simultaneously pressed. "Play" icon 11 on the menu screen 110 (FIG. 14)
It is checked whether the fourth button 92f has been pressed in a state where 2 has been selected. And "Play" icon 1
If the fourth button 92f is pressed in a state where 12 has been selected, a "play" subroutine is executed in S114.

FIG. 5 is a flowchart showing the contents of the "play" subroutine. In the first step S300 after entering this subroutine, the reference coordinates (X _N , Y _N ) and the adjustment amount (DX) are obtained from the nail coordinate table on the main memory 53 for each nail ID (where N = 0 to 9). _N , DY _N ) are read out, and the following equations (3) and (4) are executed based on the read out values, and the calculation result is expressed as nail axis intermediate coordinates (K
X _N, respectively overwritten in the column of KY _N) (corresponding to a nail coordinate moving means).

[0093]

KX _N = X _N + DX _N (3) KY _N = Y _N + DY _N (4) The following processing from S301 is a processing as a ball trajectory calculating means for calculating a ball trajectory. .

First, in S301, time measurement is started. In the next step S302, 0 is substituted for a variable j for sequentially assigning ball IDs. In the next S303, S301
It is checked whether the first cycle (0.5 seconds) has elapsed since the start of the time measurement in step (1). When it is determined that the first cycle has elapsed, it is checked whether or not the first cycle has further elapsed since the judgment. Then, if the first cycle has not elapsed yet, the process proceeds immediately to S310.

On the other hand, if it is determined that the first cycle has elapsed, the process proceeds to S304. This S3
The processes from 04 to S309 are processes for displaying (launching) one new ball. Specifically, S30
In step 4, the variable j is incremented by one. Next S30
At 5, it is checked whether the variable j has exceeded 20. If the variable j does not exceed 20, the process proceeds directly to S307, and if the variable j exceeds 20, the process proceeds to S307.
After substituting 1 for j in 306, the process proceeds to S307. In S307, the variable j corresponding to the ball ID is set to the variable j.
Substitute the value of In the next S308, the main memory 53
Ball ID that matches variable i in the ball management table above
, The initial values of TX _i , TY _i , VX _i , and VY _i are appropriately written. At this time, the initial values of the ball center coordinates (TX _i , TY _i ) are always the same (the coordinates of the base end of the launch path G),
The initial values of the ball speed vectors (VX _i , VY _i ) are the first right button 92R1 (pressed to increase the ball launch) and the first left button 92L1 (pressed to weaken the ball launch). ) And a random number appropriately generated. In the next step S309, the number of ball stocks, which is a variable indicating the possessed ball, is decremented by one. Then, after completion of S309, the process proceeds to S310.

[0096] Loop processing from S310 to S315 is processing for each ball to update its ball center coordinates (TX _i, TY _i) and ball speed (VX _i, VY _i) a. In the first step S311 after entering this loop processing, the variable i is incremented by one.

In the next S312, the ball center coordinates (TX _i , T _i ) of the ball (ball to be processed) whose ball ID matches the variable i

If Y _i ) matches the coordinate position of the winning opening, S
At 316, processing corresponding to the type of the winning opening (increase the number of ball stocks by a predetermined amount, open tulips,
Rotate the roulette, if the roulette stops at "777", call out "big hit", if the roulette stops at "7-7", play out "reach", etc.) Then, in the next step S317, data is deleted from the entry of the ball ID that matches the variable i in the ball management table on the main memory 53, and the process proceeds to S317.
Proceed to 315.

On the other hand, if it is determined in S312 that the ball center coordinates (TX _i , TY _i ) of the ball to be processed do not match the coordinate position of the winning opening, the process proceeds to S313. In S313, the ball center coordinates (TX _i, TY _i) of balls balls ID matches the variable i is checked to see if it matches the coordinate position of the out port. If the ball center coordinates (TX _i , TY _i ) of the ball to be processed match the coordinate position of the out mouth, in S317, it matches the variable i in the ball management table on the main memory 53. Data is deleted from the ball ID entry, and
Proceed to 315.

On the other hand, the ball center coordinates of the ball to be processed
(TX_i, TY_i) Does not match the coordinate position of the out mouth
If it is determined in step S313 that the process is complete, the process proceeds to step S314.

Reading direction ball speed VY _i, adds the gravitational acceleration constant predetermined for the read Y-direction ball speed VY _i, writes the addition result to the original position in the ball management table.
Here,, X-direction ball velocity VX _i is left as it is. This is because the falling trajectory of the ball is a parabola.

In the next S402, the ball center coordinates (TX _i , TY _i ) and the ball speed vector (VX _i , VY _i ) are obtained from the ball ID entry matching the variable i in the ball management table on the main memory 53. Each value is read out, and the values of the new ball center coordinates (TX _i , TY _i ) are calculated by executing the following equations (5) and (6) based on the read out values,
Overwrites the original position in the ball management table, respectively.

The process proceeds directly to S409. On the other hand, the distance between the ball center coordinates (TX _i , TY _i ) of the processing target ball and the nail axis intermediate coordinates (KX _N , KY _N ) of the nail to be checked is determined by the radius of the ball and the radius of the nail axis. If less than the combined distance, ie
