The determination is made based on whether the word is correctly stored.
If keywords are correctly stored, backup is available
Conversely, if the keyword is not correct,
Backup data has been destroyed,
Not valid. If the backup is valid (S43:
Yes), the process proceeds to S44, and each of the main control boards C
Return the state to the state before the power was turned off. In the processing from S44, first, the backup
Reads the value of the stack pointer from the area 54a
And write this to the stack pointer before power down (stop
(Before the power failure), that is, the state before the occurrence of the NMI interrupt (S

(S46), execute NMI interrupt return and process
To where it was before the power was turned off, and
Continue from the previous state. On the other hand, if the backup is not valid
(S43: No) or the clear switch 30c is on
If it is done (S42: Yes), the RAM is cleared and the
The initialization process is executed (S47), and the user work RAM
Initialize each value of 54. Here, the flow chart of FIG.
The RAM clear and initialization processing is explained with reference to the
I will tell. FIG. 7 shows an initialization process for the main control board C (S1).
2) RAM clearing and initialization processing executed in (2)
47 is a flowchart showing 47). This process is
Initialize each value of the user work RAM 54 and
A random number using the value (unique code) of the code memory 64a
By generating an initial value for updating the counter 54b,
Initial update of random number counter 54b, which differs for each pachinko machine
This is a process for generating a period value. In this RAM clearing and initialization processing,
Clear each value of user work RAM 54 to “0”
Then, an initial value is set (S51). Here, the conventional crack
In the machine, the value cleared to “0” is used as the initial value.
Since the update of the random number counter was started,
The period value becomes a fixed value (here, “0”), and the random number
This caused a decrease in the randomness of the counter. Therefore,
In the Ming's pachinko machine P, the processing described below
An initial value for updating the number counter 54b is randomly generated,
The random number counter 54b is prevented from having a reduced randomness.
ing. That is, after the processing of S51, first, the ID R
Read the value of the unique code memory 64a of AM64
(S52) The read value is stored in the user work RAM.
The data is written to the initial value setting memory 54e (S53).
The value of the unique code memory 64a is as described above.
Is a unique number unique to the MPU 11. That
Therefore, in S53, all pachinko machines of the same model
A different value for each pachinko machine is stored in the initial value setting memory 54e.
Written to Next, by the processing of S54 and S55,
The value of the initial value setting memory 54e is stored in the random number counter 54b.
(Correction) to a value within the update range of. Specifically,
The value of the initial value setting memory 54e is equal to or less than "630".
Or not, that is, a value within the update range of the random number counter 54b.
Is determined (S54). Initial value setting memory
If the value of 54e is “631” or more (S54: N
o), exceeds the update range value of the random number counter 54b
You. Therefore, in this case, in the initial value setting memory 54e,
From the value, “630”, that is, the update range of the random number counter 54 b
The processing (S55) for subtracting the upper limit value (maximum value) of the value of the box
The value of the initial value setting memory 54e is repeatedly executed.
(Correction) into a value within the update range of the random number counter 54b
(S54, S55). On the other hand, in the process of S54, an initial value is set.
If the value of the memory 54e is equal to or less than "630" (S54:
Yes), the value within the update range of the random number counter 54b
You. Therefore, in such a case, the initial value setting memory 54e
To the random number counter 54b and the current initial value memory 54c.
Write (S56, S57), random number counter 54b and
The update initial value is set in the current initial value memory 54c. What
Note that the random number counter 54b performs the processing in S56.
Using the set value as the initial value of the update, the random number update described later
The first cycle of the process (S16, see FIGS. 5 and 8)
Start the update. As described above, the update of the random number counter 54b is performed.
The initial value includes the value of the unique code memory 64a (that is, the initial value).
Processing (correcting) the value written in the value setting memory 54e)
A random value generated is set. Backup
The value of the random number counter 54b is properly held
If not, or if the clear switch 30c is pressed
When the value of the random number counter 54b is cleared,
From the randomly generated initial value, the random number counter 54b
Since updating is started, updating of the random number counter 54b is performed.
To avoid new starting from a fixed value such as "0",
Suppressing a decrease in randomness of the random number counter 54b
You can do it. Here, for example, the main control board C and another board
(For example, power supply board 30), etc.
For example, a so-called "hanging board")
A signal illegally generated from the board (for example, power failure signal 3
An illegal act of outputting 1) to the main control board C is conceivable.
For example, the power failure signal generated illegally is continuously
When the power is output to C and the power failure process occurs frequently, the main control board
C (MPU 11) must execute the power failure process normally
Is not possible, and the game state is initialized (user work R
AM 54 is initialized). Doing this
The update of the random number counter 54b is started from a fixed value such as "0".
Is started, and the randomness of the random number counter 54b is unduly low.
Let it down. However, according to the gaming machine P of the present invention,
For example, the initial value of the update of the random number counter 54b is a unique code.
Generated based on the value (unique code) of the memory 64a
Therefore, the random value differs for each pachinko machine. Yo
The person who commits the wrongdoing (illegal board) is
The detection signal of the switch 20 is illegally generated, and the illegally generated
Attempt to output the generated detection signal at the timing of jackpot
However, the value of the random number counter 54b can be grasped.
There is no, so you can not generate a jackpot fraudulently
No. Therefore, the so-called "hanging substrate"
Prevent fraudulent acts such as unfair
You can. The pachinko machine P is obtained illegally and
Code memory of MPU11 provided in pachinko machine P
Decrypt the value of 64a (unique code) and program
The control program stored in the program RAM 52 is analyzed.
Obtains the initial value of the update of the random number counter 54b
You can (grab) it. But get this fraudulently
The initial value of the update of the random number counter 54b is
This value occurs only in the pachinko machine P itself.
Then (because the unique code is different for each pachinko machine)
Causes different initial values. Therefore, the same model
For pachinko machines, a unique code for each pachinko machine
Without deciphering the information, cheating cannot be done,
As a result, such misconduct can be extremely difficult.
I can come. Returning to the flowchart of FIG.
In the process of S13, the timer interrupt is set (S13).
The timer interrupt set here is the fluctuation of LCD3.
