BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a verification system for CD-ROM software, which can be applied to, for example, a game CD-ROM.

[0002]

2. Description of the Related Art Recently, as a game system using a computer, there is a game system in which software as game contents is stored in a CD-ROM in consideration of high image quality and high speed. As is well known, a CD-ROM cannot write data, unlike a floppy disk or the like. Therefore, the verification of the CD-ROM software needs to be particularly strict. In practice, game application software handles various data such as moving images, voices, and character data. Therefore, even if each data alone is sufficient, it may not be sufficient as a whole, and verification is required.

Conventionally, the verification of the CD-ROM software has been performed by any of the following first to third methods. The first method is a method of actually creating a CD-ROM, loading the CD-ROM into a game system, and executing application software for verification. The second method is a method of executing and verifying application software in a premastering device (master manufacturing device) during premastering. In practice, the premastering device has a display and the like. Third
The method is a method of extracting a part of data that can be handled by a personal computer from the data of the application software, recording the data on a hard disk or a floppy disk, and causing the personal computer to execute the verification.

[0004]

However, all the conventional methods have problems.

Since the first method is a method for actually making a CD-ROM, the cost and time loss are large.
When debugging is required, the created CD-ROM and master disc are wasted.

The second method has a problem of occupying an expensive premastering device for a long time. Also, debugging must always be run on other systems. Furthermore, the game system itself, which originally uses the CD-ROM player, is not used for verification, and it may not be possible to make an accurate determination.

Since the third method is a verification in which a part of data is taken out, it is impossible to carry out a comprehensive verification of all the software parts of the CD-ROM, which may cause a problem after the verification. Even with this method, the original CD-ROM
The game system body using the playback device is not used for verification, and an accurate determination may not be possible.

The present invention has been made in consideration of the above points, and provides a CD-ROM software verification method capable of accurately and promptly verifying the software of a CD-ROM with a simple system. It is the one we are trying to provide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a computer game system will be described below with reference to the drawings.

FIG. 1 shows the overall construction of this embodiment. In FIG. 1, the game device main body 1 which is the verification target system is originally connected to the CD-ROM reproducing device via the CD-ROM interface unit 2, and is stored in a system card or the like (not shown). The data is read from a CD-ROM according to a system program or the like, the data is processed and converted into a video signal and an audio signal, which are given to the television monitor device 3, and the television monitor device 3 outputs and outputs the sound. ..

At the time of verifying the CD-ROM software, a pseudo CD-RO that looks like a CD-ROM reproducing device to the game device main body 1 is seen from the game device main body 1 side.
An M reproducing device (hereinafter, pseudo CD-ROM reproducing device) 10 is connected via a CD-ROM interface section 2.

In this embodiment, the pseudo CD-ROM reproducing device 10 is composed of a personal computer 11 and a hard disk device (HD) 12 connected to the personal computer 11. The hard disk loaded in the hard disk device 12 stores the application software (game software) 12a of the CD-ROM to be verified. Further, the personal computer 11 stores address conversion data 11a for converting an address output by the game apparatus body 1 to access the CD-ROM into an address on the hard disk, and a verification time program 11b shown in FIG. Has been done. The personal computer 11 executes the verification program 11b when an access command for the CD-ROM is given from the game apparatus body 1.

Further, a system RAM 4 for recording software having similar functions is provided in place of the system card used when the game apparatus main body 1 originally operates. Such changes are described below.
This is because not only the game apparatus body 1 but also the debugging personal computer 13 uses the stored contents of the RAM 4.
