When accessing 0, address data is provided through the pass line Bt-.

In addition, the keys 7 include game progress keys, mode switching keys, numeric keys, etc., and each key is operated by the sub CPU 16.
The key scanning signal from the sub CPU 16 is detected as a key operation signal and is sent to the sub CPU 16. When saving and loading, the sub CPU 16 not only provides address data to the sub memory 13 through the pass line bt-, but also reads the game program from the sub memory 13, executes the game, and executes the process via the driver 17 as described above. The images are displayed sequentially on the liquid crystal display @8.

The upper buffers 11 and 12 are the main CPU'1 respectively.
4. Input/output control cannot be performed when writing, saving, and loading each control evip number C and c from the CPU 16.

Furthermore, the main CPU 14 and the sub CPU 16 are directly connected through the control signal lines E and e, so that when the above save or load is performed, the main CPU 4 connects the sub CPU 1 to the sub CPU 1.
A write signal 'vV R, a read signal RD, a selection (chip enable) signal CE, and an instruction code transfer signal OP are given to the main CPU 14 from the sub CPU 16, and a busy signal BUSY and an interlat signal INT are given to the main CPU 14 from the sub CPU 16. There is no transfer control.

To load the game program from the child electronic game device 6 to the child boom device 6, place the child electronic game device 6 into the storage ftB4.
, and sweep the storage section selection key and load key corresponding to the storage section 4. Then, as shown in FIG. 3, when the main CPU 14 detects the operation signal of the storage section selection key, it gives the selection signal CE'r to the sub CPU 16, thereby selecting the path from the children's electronic game device fIt6 to be loaded. When the line is opened and the operation signal of the load key is detected, the instruction code transfer signal OP is also sent to the sub CPU1.
6, the load instruction code is transferred and outputted via the pass line A-Ds a, and after a slight delay, the write signal WR is also applied to the sub CPU 16, whereby the load instruction code is transferred to the sub CPU 16. written. The sub CPU 16 gives a busy signal BURY to the main CPU 14.

After loading the load instruction code 1, the sub CPU
16 stops outputting the busy signal BUSY, thereby causing the main CPU 14 to stop outputting the write signal WR,
After a slight delay, the output of the selection signal CE and the instruction code transfer signal OP is also stopped. Then, the sub CPU 16 gives a continuous command signal to the tap memory 13 based on the load instruction code read in t'.

Next, the main CPU 14 again applies the selection signal CE to the sub epui 6, whereby the start address data for reading of the sub memo 1713 is transferred and output via the pass line A%Dsa, and after a slight delay, the write signal WR is also applied to the sub memo 1713. C.P.
The head address data is then written to the sub ePU 16. During this time, sub CPU 1
6 provides a busy signal BUSY to the main CPU 14.

After writing the start address data, the sub CPU
No. 16 stops the output of the busy signal BUSY, and as a result, the main CPU 14 stops the output of the write-in No. 8 WR, and with a slight delay also stops the output of the selective supply CE. Then, the sub-CPU 16 supplies the invested first application address data to the sub-memory 13 via the bus twin b, and uses it as the read-first application address data of the sub-memory 13.

At this time, the main Ci'U 14 specifies the start address of the empty area in the main memory 10 via the pass line B based on the detection of the operation signal of the load key.

Then, the main CPU 14 again receives the selection signal CE.
is given to the sub CPU 16, and after a slight delay, the read signal R is sent to the sub CPU 16.
D is also given to sub CPU 16, and this also gives sub CPU 1.
6 reads out the game program of game 4 from the starting address of the sub-memory 13, and this program is transferred and outputted via the pass line 8% D% A'f- and written into an empty area of the main memory 10. During this time, the sub CPU
16 provides a busy signal BUS'Y to the main CPU 14.

When the loading of the program at the start address of the game program of game 4 is completed, the sub CPU 16 outputs the busy signal B.
The output of USY is stopped, and the main CPU 14
stops the output of the read signal RD, and after a slight delay, also stops the output of the selection signal CE.

Then, the sub CPU 16 increments the address data for the sub memory 13 by one.

Then, the main CPU 14 sends the selection signal CE and the slightly delayed read signal RL to the sub CPU 1 in the same manner as described above.
As a result, the program at address 9 next to the start address of the game program of game 4 in the submemory 13 is rolled.

By repeating this operation, the game zolograms of game 4 are loaded one after another, and when the program at the final address is loaded, the loading ends. When the loading is completed, the game 4 loaded in the main memory 10 can be selected by operating the game select key, game key, and game advance key for game 4 on the keyboard 2. The program is read and extracted, and the game execution process is performed by the CPU 14, and this execution process is displayed on the CRT display device 3 via the CRT controller 15.

In this way, the game of the children's electronic game device 6 is completed.
You can enjoy powerful games using the large operation keys on the keyboard 2 of the CRT display device 3 on the first screen. You can touch the bumps.

Also, if you insert the unique children's electronic game device M6 into another storage section 4 and perform the same operation, the game program will be loaded into the remaining empty area of the main memory 10. You can set up 7 games and have fun.

Note that in order to execute the game of this child electronic game device 6 on the parent electronic game device 1, the game program is not loaded and the main CPU 4 of the parent electronic game device 1 is executed by the child υ.
The game program in the submemory 13 of the child game device 6 may be directly read. In this case, the instruction code to be transferred is not "load" but "read".

Next, the parent selects the child electronic game device 1 to save the program from the child game device 1 to the child electronic game device 6. , put the device 6 into the storage section 4, and operate the storage section selection key corresponding to the storage section 4, the game selection key and the save key for the game you want to save, for example, the game 9-2 shown in FIG. . Then, as shown in FIG. 5, when the main CPU 14 detects the operation signal of the storage section selection key, it gives a selection signal GE to the sub CPU 16, which in turn sends a pass line to the child's electronic game device 6 to be saved. is opened, and when the operation signal of the save key is detected, an instruction code transfer signal oP is also given to the sub cPU 16, and the instruction code of the save key is transferred to the pass line As.
The write signal WR is also applied to the sub CPU 6 with a slight delay, and the save instruction code is written to the sub CPU 16 by force. During this writing, the sub CPU 16(, j) gives a busy signal BUSY to the main CPU 14.

After writing the save instruction code, the sub CPU
The main CPU 14 stops outputting the 16-bit busy signal BUSY, and thereby stops outputting the write signal WR, and with a slight delay also stops outputting the selection signal CE and instruction code transfer No. 4M oP. Then, the sub-CPU 16 sends the full 1-load command signal to the sub-memory 13 based on the written save instruction code.

Next, the main CPU 14 again applies the selection signal CEt to the CPU 16, so that the first address data for 1 in the submemory 13 is set to the path line A-Dsa'.
The write signal WR is also given to the sub CPU 16 with a slight delay, thereby writing the above-mentioned head address data to the CPU 16. During this time, the sub CPU 16 sends the busy signal BUSY to the main CPU 1.
It is given to 4.

After writing the start address data, the sub CPU
16 stops outputting the busy signal BUSY, which causes the main CPU 14 to stop outputting the write signal WR, and with a slight delay also stops outputting the selection signal CE. Then sub C
The PU 16 provides the written start address data to the sub-memory 13 via the pass line bl, and the sub-memory 13
Specify the start address for writing.

Further, at this time, when the main CPU 14 is given the operation signal of the game selection key of the game 2, the main CPU 14 sends the start address data of the game program of the game 2 in the main memory 10 corresponding to the selected game to the main CPU 14 via the path line El. The address of the main memory 10 is specified by applying the address to the memory lO and b.

Then, the main CPU 14 also gives the old layer selection signal CE to the sub CPU 16, and after a slight delay also gives the biting signal WR to the sub CPU 16, so that the game program at the start address of game 2 in the main memory 10 is changed to pass line A%. It is written to the transfer force sensing sub-memory 13 via D and a.

During this time, the sub CPU 16 also sends the busy signal BUSY to all main CPUs 14.

When the program at the start address of the game program for game 2 is saved, the sub CPU 16 outputs a busy signal B.
The main CPU 14 stops outputting the write signal WR, and after a slight delay outputting the selection signal CB.
output will also stop.

Then, the sub CPU 16 increments the address data for the sub memory 13 by one.

Then, the main CPU 14 gives the selection signal CE and the slightly delayed write signal WR to the sub CPU 16 in the same manner as described above, thereby causing the next address of the game program of game 2 in the main memory IO to be 20 logs of addresses are saved.

By repeating this operation, the game program for game 2 will be saved once. The saving process ends when the program at the final address is safe. When the save is finished, the child's electronic game device 6
By pulling out the game program from the storage part 4 and operating all the game progress keys in the key 7, the game program of game 2 saved in the sub memory 13 is read out and the sub CP
Game execution processing is performed at U16, and this execution process is displayed on the liquid crystal display device 8 via the driver 17vi.

In this way, it is possible to enjoy the games in the parent electronic game device AL on the child's electronic game device F6, which is convenient to carry. We can solve this.

Furthermore, when the child's electronic game device f6 is inserted into another storage section 4, the operation of the storage section selection key of key date 2 may be changed accordingly. Furthermore, if you want to save another game, you can change the operation of the game selection key (key 2) accordingly.

In doing so, the same save operation as described above is performed only by changing the address designation from the main CPU 14 to the main memory 10.

In this way, it is also possible to arbitrarily select and set a large number of games on the child's electronic child game device 6.

In addition, this Example 1-1: As shown in FIG.
