The security code indicates that the CD-ROM disk 10 is duly licensed by a television game device maker. As shown in FIG. 1(c), the security code is recorded in a security region 16b at a preset address in the boot sector 16.
As shown in FIG. 1(d), the security code contains a program to be executed after a checking operation of the security code, color data indicative of colors of LOGOTYPE to be displayed, LOGOTYPE pattern data indicative of patterns of LOGOTYPE to be displayed, message data indicative of a message "PRODUCED BY OR UNDER LICENSE FROM XXXX KABUSHIKI KAISHA), and sound data indicative of a licensor television game device maker. This embodiment is especially characterized in that a program itself to be executed following a checking operation of the security code is contained in the security code.
A program involved in this embodiment is executed by a main CPU of television game device. As shown in FIG. 1(d), the program includes seven steps.
In the first step, an address the main CPU jumps when the television game device is reset is set.
In the second step, a sub-CPU provided in the CD-ROM device for the CD-ROM disk to be mounted on is temporarily paused.
In the third step, contents of the program memory of the sub-CPU are rewritten in data recorded in the CD-ROM.
In the fourth step, the operation of the sub-CPU which has been temporarily paused is resumed.
In some television game devices, these second through fourth steps may be omitted.
In the fifth step, head addresses of data recorded in the CD-ROM disk are set in a register of the main CPU.
In the sixth step, a required program routine stored in the CD-ROM device is executed. This program routine performs a resetting operation, such as license display.
The program routine involved in this embodiment performs the following resetting operation.
First a vertical interrupt address is set. Next, a sound processor and a video processor are reset, while a video RAM is cleared, and ASCII character graphics are set. Then, based on color data stored in the security code 16b, display colors are set, and based on LOGOTYPE data in the security code 16b, LOGOTYPE character graphics are set. Subsequently message data (PRODUCED BY OR UNDER LICENSE FROM XXXX KABUSHIKI KAISHA) in the security code 16b are displayed on a television screen, and a LOGOTYPE map is set to display LOGOTYPE on the television screen. Then, after one second, based on sound data stored in the security code 16b, sounds indicative of a licensor television game device maker are outputted, and a LOGOTYPE mark color is changed, and then the television screen display is cleared.
Finally in the seventh step, a jump is performed to an application program, such as a game program.
A CD-ROM disk security check method according to one embodiment of the present invention will be explained below with reference to FIGS. 2 and 3.
In the flow charts of FIGS. 2 and 3, Steps 101 to 106 are for checking the security code by the sub-CPU of the CD-ROM device provided in the television game device for mounting the CD-ROM disk. Step 107 and its following steps are for operation by the main CPU provided in the television gate device.
First it is judged whether or not one piece read from the CD-ROM 10 is a ROM track (Step 101). If it is not a ROM track, it is judged a musical disk.
It if is judged a ROM track, the first sector of the boot sector 16 is loaded (Step 102). Next, a disk identifier recorded in the identifier region 16a of the boot sector 16 is compared with a disk identifier stored in the memory of the CD-ROM device (Step 103).
If it is judged that the recorded identifier does not agree with the stored identifier, it is judged whether or not all the sectors of the boot sector 16 have been loaded (Step 104). If all the sectors of the boot sector 16 have not been loaded, a next load sector is set (Step 105), and the processing is returned to Step 102. If all the sectors of the boot sector 16 have been loaded to judge that the recorded identifier does not agree with the stored identifier, the disk is judged to be a CD-ROM disk but a disk other than a game disk.
When the recorded identifier agrees with the stored identifier in Step 103, then a security code recorded in the security region 16a in the boot sector 16 is compared with the security code stored in the memory of the CD-ROM device (Step 106). If the recorded security code agrees with the stored security code, the CD-ROM disk is judged a duly licensed proper game disk. If the recorded security code does not agree with the stored security code, the disk is judged a different disk.
The processing heretofore is the operation of the sub-CPU provided in the CD-ROM device. This processing is followed by the operation by the main CPU provided in the television game device.
First, it is judged whether or not the loaded CD-ROM disk 10 is a game disk (Step 107). If the disk is not a game disk, the operation for the usual music CD . .tis.!. .Iadd.is .Iaddend.enabled (Step 108). Incessantly it is judged whether or not the tray of the CD-ROM device is opened (Step 109), and when it is judged that the tray is opened, there will be a possibility that the loaded CD-ROM disk 10 has been replaced, and the processing is returned to Step 101.
In Step 107, when the loaded CD-ROM disk 10 is judged a game disk, "CD-ROM" is displayed on the television screen (Step 110), and both the operation of the usual musical CD and the game operation are enabled (Step 111). It is incessantly judged whether or not the tray is opened (Step 112), and if the tray is judged opened, there is a possibility that the CD-ROM disk 10 has been replaced, and the processing is returned to Step 101.
Subsequently it is judged which has been selected between the usual musical CD operation and the game operation (Step 113). If the game operation is selected, Step 114, which will be explained below, will follow.
First, the security code is loaded from the CD-ROM disk (Step 114). Then a program contained in the security code starts to be executed (Step 115).
The first step of the program is executed, and an address for the main CPU to jump when the television game device is reset is set (Step 116).
Then, the second step of the program is executed, and the operation of the sub-CPU provided in the CD-ROM device is temporarily paused (Step 117).
Next, the third step of the program is executed, and contents of the program memory of the sub-CPU is rewritten in data recorded in the CD-ROM disk (Step 118).
Then the fourth step of the program is executed, and the sub-CPU which has been temporarily paused is resumed (Step 119).
In some television game devices, these steps 117 to 119 can be skipped.
Then the fifth step of the program is executed, and the head addresses of data recorded in the CD-ROM disk are set in a register provided in the main CPU (Step 120).
Next, the sixth step of the program is executed, and a required program routine stored in the CD-ROM device is executed (Step 121). In this program routine, resetting operation including the above-described license display, etc. is performed.
Returning from the program routine stored in the CD-ROM device, the seventh step of the program is executed to jump to an application program (Step 122), and the execution of the application program of a game or others is started, and the security check operation of the CD-ROM disk is finished.
The present invention is limited to the above-described embodiment and covers other various modifications. For example, the program contained in the security code is not limited to the program involved in the above-described embodiment and may be any kind of program.
