Description

Specification

Regeneration system technical field

The present invention relates to a system for reproducing a medium in which data is stored in a multi-session system when the medium is applied to a game machine. Background art

Conventionally, the format of a CD in which audio and CD-ROM are recorded on a single CD is mainly divided into audio data (CD-DA) and ROM called mixed mode CD or CD-ROM ready. Data is written in a single session, and multi-session in which CD-DA and ROM data are written in separate sessions.

In the latter CD, the CD-DA and ROM data are written to separate sessions, so that the ROM data can be hidden from the CD-DA. CD-EXTRA (CD-Extra) is one of the multi-session methods and was standardized by Philips and Sony in 1995. This CD-EXTRA format specifies where song titles, lyrics, and jacket images should be written.

According to this CD-EXTRA, in addition to the original CD-DA function (the function of playing music on a CD player), various images are developed when the same disc is played on a personal computer. It can be added to a single recording medium. In other words, not only the expression of sound but also the expression as a video can be added to one disc, so that the user can touch more information, and the CD provider only uses the audio expression. Instead, more various expressions can be conveyed to the user. As described above, CD-EXTRA is known as a medium that can be played on a personal computer. When a user plays this CD on a personal computer, the user must use the CD-DA function or the CD-ROM function. You need to choose.

In recent years, home video game consoles, which are rapidly penetrating into homes, are configured so that a CD-ROM and a music CD having a gigabyte-level storage capacity for storing game programs are applied. Recording media written in the session is not configured to be applicable. Even if a home game machine is configured to be able to play CD-EXTRA, it must have a playback system that takes into account the characteristics of a home game. Disclosure of the invention

An object of the present invention is to provide a novel system for applying a recording medium written in multiple sessions such as a CD-EXTRA to a game machine.

The playback system according to the present invention, when playing back a medium stored in a multi-session by a game machine, particularly a home-use game machine, determines that the medium set by the detecting means is a medium stored in the multi-session. A reproducing means is provided for reproducing the ROM data session of the medium by prioritizing the audio data session by detecting it.

After the same input as that for reproducing the game recording medium on the game machine is performed, the reproducing means reproduces the ROM data session of the medium stored in the multi-session in preference to the audio data session. It is characterized by. The input for reproducing the game recording medium on the game machine indicates that the game machine is powered on.

In other words, when applied to game consoles, it is anticipated that many users will prioritize ROM data over CD-DA. Therefore, the same operation as starting the game on the game recording medium, that is, turning on the power of the game machine, causes the audio data Reproduce ROM data in preference to the session.

This priority reproduction makes it possible to differentiate from a personal computer in a multi-session type storage medium reproduction system.

Further, as an embodiment of the present invention, a boot ROM for starting a game machine is provided, and when the detecting means recognizes that the medium is a medium stored in a multi-session, the boot is performed. Control is performed to output the special logo in the ROM to the display.

The unique information is, for example, a dedicated logo, which can recognize a difference from ordinary game software and notify a user that the function is equivalent to multiple functions. Also, the type of the medium is recognized based on a combination of the display of the unique information in the dedicated boot ROM and the unique information in the medium stored in the multi-session and the display order.

The unique information in this medium is stored in the ROM data session. According to the present invention, the combination and / or order of display of the unique information of the hardware of the game machine body (such as a dedicated logo of the hardware) and the unique information of the medium (such as the dedicated logo stored in the medium) are appropriately set. By doing so, the type information of the medium applied to the game machine can be given to the player, or the player can recognize or confirm whether the medium is operating properly. This exclusive logo has a form such as displaying a single word or multiple logos in order or combining them. “Unique information” refers to information unique to the hardware of the game machine itself or a special logo (mark) for the recording medium, and the special logo is not particularly limited to a company name, a trademark name, a product name, or the like.

Further, in the present invention, as an embodiment, a communication software may be stored in the session of the ROM data, and the communication with the communication software makes it possible to access the dedicated server.

In addition, the ROM data of the storage medium in which the data is stored in the multi-session method. In the session, it is possible to selectively store an application conforming to the control specifications for each operation of a plurality of types of game machines including the game machine or an application conforming to the OS of a personal computer. It is characterized by

“CD-ROM” refers to a compact disk (CD) type recording medium in which game programs and the like are recorded in a non-rewritable (read, only, memory) state, and “CD-EXTRA” refers to music information. An area (CD-DA) for recording data and the like and an area (ROM data session) having the function of the CD-ROM exist on one CD. BRIEF DESCRIPTION OF THE FIGURES

Subunit 3 functions not only as a sub-monitor device that displays sub-images in response to commands transferred from game console 1 via controller 2, but also as a portable game device that can operate independently. It is configured.

Specifically, the subunit 3 includes a CPU 30 interface circuit 31, a RAM 32, a ROM 33, an oscillation circuit 34, a speaker 35, a piezo drive circuit 36, and a piezo element 37. , A liquid crystal driver 38, a sub monitor 39, and an operation button group 40.

The interface circuit 31 enables data transmission and reception with the controller 2.

RAM 32 is an operation area of CPU 30. The ROM 33 stores a program for operating the sub-unit 3 as a portable game device, and also stores sub-image data for operating the sub-unit 3 as a sub-monitor device. This sub-image data is an image corresponding to the image generated by the game machine body 1. The oscillating circuit 34 generates a sound signal of a constant frequency under the control of the CPU 30, and the speed controller 35 can convert the sound signal into sound. These (34, 35) are sound generation mechanisms that enable a player to recognize a sound of a predetermined frequency (about 1 kHz), such as the sound of “pip-pip” used in mobile phones. Other configurations, such as a buzzer, may be used as long as they can occur.

The piezo drive circuit 36 generates a drive signal of a constant frequency under the control of the CPU 30, and the piezo element 37 receives this signal and performs electromechanical conversion to convert the signal into vibration of a constant amplitude. These (36, 37) are vibration generating mechanisms. Other configurations such as an eccentric motor may be used as long as a predetermined vibration can be generated so that the player can recognize the vibration, such as a vibration used in a story.

The LCD driver 38 has a video memory, and is configured to be able to update the drawing data of the video memory under the control of the CPU 30. The sub-monitor 39 is configured to be able to display the drawing data stored in the video memory as an image. ing.

These (38, 39) need only be configured so that characters and images can be recognized by the player, like LCDs in portable information terminals.

The CPU 30 causes the sub-monitor 39 to display a sub-image corresponding to the game processing in the game machine body 1 based on the program stored in the ROM 33. Then, when a command is transmitted from the game console 1 via the interface circuit 31, new sub-image data is read from the ROM 33 in accordance with the command and displayed on the sub-monitor 39. The sub-image is updated. When the content of the command indicates the generation of sound, the CPU 30 operates the oscillation circuit 34 to generate sound, thereby stimulating the hearing of the player. Further, when the content of the command indicates generation of vibration, the CPU drives the piezo drive circuit 36 to transmit vibration to the player holding the sub-unit to stimulate the tactile sensation of the player. It has become.

In the above configuration, the subunit was connected to the controller 2 via the connection cable 160 as shown in FIG. 1, but as shown in FIG. 12, the subunit 3 was not connected via the connection cable 160. Alternatively, it may be directly connected to the connector of the controller 2. As a result, the game machine body 1 and the controller 2 constitute a game machine body side set.

Hereinafter, the operation of the present embodiment will be described with reference to the flowchart of FIG. First, when the power is turned on, the control means of the game machine main body executes this flowchart. After the start, the process proceeds to step 452 to change the flow path of the flowchart to S458 or S460, as described later, depending on whether or not CD200 is loaded. Branch.

(When loading CD → power on)

In step 452, if the affirmative determination is made, that is, if the power is turned on while the CD 200 is loaded in the game machine main body, the process proceeds to step 460, where the boot ROM is started up and the game machine is The logo stored on the main unit is displayed. The operation up to this point is executed regardless of whether the loaded recording medium is a dedicated CD-ROM on which ordinary game software is recorded, a music CD, or a CD-EXTRA.

In the next step 510, the type of the loaded CD 200 is determined. Then, in step 512, the determined CD 200 is loaded into a dedicated CD-ROM 200R storing a game program for a game machine. In this case, the process proceeds to step 514, where the logo mark (medium-specific information) stored on the medium side is displayed. Then, in step 515, it is determined whether or not the start button of the controller has been operated by the operation button. Is done. If an affirmative determination is made in step 515 (that is, the player operates the start button), the flow advances to step 516 to read the game program from the dedicated CD-ROM 200R and start the game. .

If it is determined in step 512 that the music is a music CD, the flow directly proceeds to step 518 to control the reproduction of the music recorded on the music track. Next, when it is determined in step 512 that the CD is EXTRA 200X, the process proceeds to step 520. At step 520, a mark for exclusive use of the CD-EXTRA on the medium side is displayed, and then at step 522, the video data of the CD-EXTRA is automatically read. At step 524, based on the read video data, a video based on the video data is displayed (see FIG. 7). The logo of step 520 and the logo of step 514 may be the same or different. In other words, the CD-EXTRA 200 X can be started automatically when the power is turned on. The operability is greatly different from the case where a user is used.

In the next step 526, various operation button guidance displays appear as a part of the displayed video data by operating one of the operation buttons of the controller 2 of the game machine of the user. An example of the button guidance display mode is shown in FIG. 8 which is a part of FIG. That is, a symbol similar to the actual operation button of the CD player is displayed in the form of an icon at the bottom of the screen as an operation button guidance display. The player can select one of the button guidance displays by operating a direction key or the like of the controller, and press an enter key to select an operation mode corresponding to the button guidance display. Operate the decision button. As a result, an operation based on the operated content is performed (step 528).

Next, if the power is turned on first before loading the CD 200 into the game machine, the process proceeds from step 452 to step 458 to start the boot ROM, and the game machine is set for a predetermined time. After displaying the logo on the side, a menu screen as shown in Fig. 9 is displayed (step 550).

In the next step 552, it is determined whether or not CD 200 is loaded. If the determination is affirmative, the process proceeds to step 554, and one of the buttons on the menu screen is clicked. Is determined. If it is determined that any of the buttons (“File”, “Play”, “Sound”, “Set”) has been selected, the process proceeds to step 556 to recognize the connector corresponding to each button. . Next, in step 558, the type of the loaded CD 200 is determined, and in step 560, it is determined whether or not the type of the loaded CD 200 matches the selected button. Is determined. Step 558 may be executed before step 554. Here, if it is determined that they match, the process proceeds to step 562, jumps to the connector code corresponding to each button in step 556, and continues the process. If it is determined that they do not match, the process proceeds to step 564 to display a message indicating the mismatch. And return to step 554.

If the attached CD is a dedicated CD-ROM, the play button is selected to jump to 514 via step 562. If the loaded CD is an EXTR A-CD, the play button is selected in the same way as the dedicated CD-ROM, and through step 562, the dedicated logo, which is the unique information of the game console itself, is displayed again. And then jump to step 520. The connector D is a functional unit for setting the operating environment of the game machine, and will be described with reference to FIG. The connector B is a functional unit for processing a file in the storage area of the game machine, but the description is omitted. Further, instead of the processing of steps 554 to 564, the processing may shift to step 215 after step 552.
