Description

  The present invention relates to a program, an information storage medium, a game machine, a server, and a network system.

  Conventionally, a role playing game in which a player character operated by a player performs a transaction or a battle using an item to achieve a predetermined purpose is known. Such a role-playing game can save save data obtained by executing the game, and can later resume the game by loading the save data.

  However, in recent years, in such role-playing games, a player illegally duplicates an item, an act of registering an illegally duplicated item in save data and playing a game, and a player illegally exchanges an item with another player. It is a problem that the game balance of the game cannot be maintained due to an action deviating from the original game, such as an action of multiplying items and playing a game.

Conventionally, there is known a technique for prohibiting an act of illegally duplicating game data used for game calculation of an item or the like (Patent Document 1 and Patent Document 2). However, these conventional methods only prevent specific duplication actions and cannot completely prevent all duplication actions. In addition, if the duplication action cannot be prevented, the duplicated game data can be used as it is in the game as in the original.

For example, the display flag is set to true for the data acquired according to the acquisition format (for example, the format for acquiring data by the ad hoc mode) other than the first acquisition format (format for acquiring data by the infrastructure mode) In addition, the display flag can be set to false for the data acquired according to the first acquisition format.

  Further, the flag setting unit 116 can set a flag according to the acquisition format for the item included in the save data. For example, the item acquisition format is the first acquisition format (a format in which the player character acquires items based on data acquired in the infrastructure mode) or the third acquisition format (the player based on the action result of the player character in the game). If the character is an item acquisition format), the transaction flag is set to true, and the item acquisition format is the second acquisition format (the player character acquires the item based on the data acquired in the ad hoc mode). Format), the transaction flag can be set to false.

  The display control unit 118 performs processing for displaying data used for game calculation on the display unit. In particular, the display control unit 118 of the present embodiment performs a process of causing the display unit to display the data to be transmitted to be transmitted to other game machines. For example, data with a true display flag set in the flag setting unit is displayed on the display unit as data that can be selected as a transmission target, and data with a false display flag is displayed on the display unit as data that can be selected as a transmission target. Processing that is not displayed can be performed.

  The drawing unit 120 performs drawing processing based on the results of various processing (game processing) performed by the processing unit 100, thereby generating an image and outputting the image to the display unit 190. When generating a so-called three-dimensional game image, first, object data (model data) including vertex data (vertex position coordinates, texture coordinates, color data, normal vector, α value, etc.) of each vertex of the object (model) ) Is input, and vertex processing (shading by a vertex shader) is performed based on the vertex data included in the input object data. When performing the vertex processing, vertex generation processing (tessellation, curved surface division, polygon division) for re-dividing the polygon may be performed as necessary. In the vertex processing, according to the vertex processing program (vertex shader program, first shader program), vertex movement processing, coordinate conversion (world coordinate conversion, camera coordinate conversion), clipping processing, perspective processing, and other geometric processing are performed. On the basis of the processing result, the vertex data given to the vertex group constituting the object is changed (updated or adjusted). Then, rasterization (scan conversion) is performed based on the vertex data after the vertex processing, and the surface of the polygon (primitive) is associated with the pixel. Subsequent to rasterization, pixel processing (shading or fragment processing by a pixel shader) for drawing pixels (fragments forming a display screen) constituting an image is performed. In pixel processing, according to a pixel processing program (pixel shader program, second shader program), various processes such as texture reading (texture mapping), color data setting / change, translucent composition, anti-aliasing, etc. are performed, and an image is processed. The final drawing color of the constituent pixels is determined, and the drawing color of the perspective-transformed object is output (drawn) to the drawing buffer 174 (a buffer capable of storing image information in units of pixels; VRAM, rendering target). That is, in pixel processing, per-pixel processing for setting or changing image information (color, normal, luminance, α value, etc.) in units of pixels is performed. Thereby, an image that can be seen from the virtual camera (given viewpoint) in the object space is generated. Note that when there are a plurality of virtual cameras (viewpoints), an image can be generated so that an image seen from each virtual camera can be displayed as a divided image on one screen.

  The vertex processing and pixel processing are realized by hardware that enables polygon (primitive) drawing processing to be programmed by a shader program written in a shading language, so-called programmable shaders (vertex shaders and pixel shaders). Programmable shaders can be programmed with vertex-level processing and pixel-level processing, so that the degree of freedom of drawing processing is high, and expressive power is greatly improved compared to conventional hardware-based fixed drawing processing. Can do.

  The drawing unit 120 performs geometry processing, texture mapping, hidden surface removal processing, α blending, and the like when drawing an object.

  In the geometry processing, processing such as coordinate conversion, clipping processing, perspective projection conversion, or light source calculation is performed on the object. Then, object data (positional coordinates of object vertices, texture coordinates, color data (luminance data), normal vector, α value, etc.) after geometry processing (after perspective projection conversion) is stored in the object data storage unit 176. Is done.

  Texture mapping is a process for mapping a texture (texel value) stored in the texture storage unit of the storage unit 170 to an object. Specifically, the texture (surface properties such as color (RGB) and α value) is read from the texture storage unit of the storage unit 170 using the texture coordinates set (given) to the vertex of the object. Then, a texture that is a two-dimensional image is mapped to an object. In this case, processing for associating pixels with texels, bilinear interpolation or the like is performed as texel interpolation.

  As the hidden surface removal processing, hidden surface removal processing can be performed by a Z buffer method (depth comparison method, Z test) using a Z buffer (depth buffer) in which Z values (depth information) of drawing pixels are stored. . That is, when drawing pixels corresponding to the primitive of the object are drawn, the Z value stored in the Z buffer is referred to. Then, the Z value of the referenced Z buffer is compared with the Z value at the drawing pixel of the primitive, and the Z value at the drawing pixel is a Z value (for example, a small Z value) on the near side when viewed from the virtual camera. In some cases, the drawing process of the drawing pixel is performed and the Z value of the Z buffer is updated to a new Z value.

  α blending (α synthesis) is a translucent synthesis process (usually α blending, addition α blending, subtraction α blending, or the like) based on an α value (A value).

  The α value is information that can be stored in association with each pixel (texel, dot), for example, plus alpha information other than color information. The α value can be used as mask information, translucency (equivalent to transparency and opacity), bump information, and the like.

  The sound generation unit 130 performs sound processing based on the results of various processes performed by the processing unit 100, generates game sounds such as BGM, sound effects, or sounds, and outputs the game sounds to the sound output unit 192.

  The processing unit 100 includes a communication control unit and a network setting unit. The network setting unit performs processing for acquiring and managing information necessary for the network system. The communication control unit generates a packet to be transmitted to another game machine, processes to specify a network address of a game machine that is a packet transmission destination, a process to save the received packet in the storage unit 170, and analyzes the received packet Control processing of the communication unit 196 related to processing and other packet transmission / reception is performed.

3. 3. Method of this embodiment 3.1 Save data identification information registration method The server of this embodiment employs a method of registering save data identification information associated with save data of a game machine. This is because the server can generate an import file that can register game data only in specific save data based on the save data identification information. That is, the import file transmitted to the game machine by the server according to the present embodiment includes save data identification information. The save data identification information contained in the import file and the save data associated with the save data of the game machine are included. Unless the data identification information matches, the game machine cannot register the game data included in the import file in the save data. In order to support such a game machine, it is necessary to include save data identification information in the import file transmitted from the server. As a prerequisite, the server saves data identification information associated with the save data of the game machine. Must be registered in advance.

  The server according to the present embodiment obtains an export file including save data identification information associated with save data of the game machine from the game machine or the terminal via the network. The export file acquired by the server includes status data of the player character to be operated by the player included in the save data, in addition to the save data identification information.

  The export file is generated by exporting the save data in the game machine of the present embodiment. More specifically, first, save data to be exported is selected based on the operation of the player. Here, “exporting” refers to extracting save data identification information and status data from the save data, and generating a file in a format that can be analyzed by the server of this embodiment. That is, the export file is generated by extracting the save data identification information corresponding to the save data and the player character status data stored in the save data from the selected save data.

  FIG. 4A shows an example of a screen displayed on the display unit of the game machine when the player selects save data. The display unit displays the contents such as the game name, the date and time when the save data was saved, the save data size, the player character name, and the level as the contents of the save data. The player can select save data to be exported by selecting “OK”. And the game machine of this embodiment performs the export process of the selected save data, and produces | generates an export file.

  The generated export file can be uploaded from the game machine to the server. In addition, you may upload to a server from a terminal using the portable information storage medium of a game machine.

  And the server of this embodiment performs the process which matches the save data identification information contained in the export file uploaded to the server from the game machine, and status data in the storage unit in association with the accessing user ID. . The server also performs processing for generating mercenary data based on the status data included in the export file. The mercenary data can be a my character for the uploaded player.

  For example, the server of the present embodiment generates mercenary data 1 based on status data included in an export file uploaded by player A. When player B logs into the server, mercenary data 1 can be downloaded as game data. On the other hand, when the player A logs in to the server, the player A cannot download the mercenary data 1 and can refer to the generated mercenary data 1 as a my character.

  In the network system of this embodiment, mercenary data (my character for a logged-in player) can be disclosed based on the WWW function of the server.

  FIG. 4B is an example of a screen on which the player's My Character is displayed on the Web browser of the terminal after the game machine of the present embodiment uploads the export file to the server. In other words, this is an example of a screen displayed on the Web browser after an export file generated based on the save data of the game machine operated by the player is uploaded to the server and the player logs in with his / her user ID.

  On the screen 41, the my character of the logged-in player is displayed. By pressing the “Upload” button on the screen 41, the player can upload the export file any number of times, and can update my character any number of times. For example, a player character raised by the progress of the game can be uploaded each time it grows.

  On the screen 42, data relating to mercenaries such as the number of downloads from other players is displayed. The screen 43 displays a download history in which the player character mercenary has been downloaded to another player.

  Note that the export file uploaded to the server by the game machine may be encrypted. In such a case, the server performs a process of decrypting the acquired export file.

3.2. Method for Registering Game Data in Saved Data The game machine or terminal according to the present embodiment can acquire game data (data relating to items and mercenaries) desired by the player by accessing the server. Specifically, the server of this embodiment generates an import file including game data and save data identification information associated with the accessing user ID. And a server can transmit an import file according to the request | requirement of a game machine or a terminal. The game machine of this embodiment can register the acquired game data in the save data by importing the import file.

  FIG. 5 is an example of a screen displayed when the player displayed on the terminal selects a desired item and downloads the item. The screen displayed on the game machine can be the same. For example, a list of items is displayed on the screen 51 shown in FIG. Then, the player can select an item by checking the desired item. When an item is selected on the screen 51 and “pack” is pressed, the contents packed in the item list on the screen 52 are displayed. The “pack” in the present embodiment is an import file generated by storing data including one or more items and saved data identification information associated with the logged-in user ID in one file. is there. Then, when the player presses the “Download Pack” button, the import file (pack) can be downloaded to the game machine or the terminal. When downloading a pack generated in the past, a past list displayed on the screen 53 of FIG. 5 can be selected and downloaded.

  FIG. 6 is an example of a screen displayed when a mercenary appearing in the game of the game machine of the player is selected and the selected mercenary list is downloaded. The screen displayed on the game machine can be the same. A screen 61 in FIG. 6A is a screen on which mercenary data stored in the game data storage area 275 of the server can be searched. For example, a search can be performed using a name, a level, or the like as a search condition. A search result is displayed on the screen 62 of FIG. When the displayed mercenary is selected, for example, as shown in FIG. 6B, detailed contents such as the image, name, and level of the selected mercenary are displayed. If the player wants to add the displayed mercenary to the list, the player presses the “Register in mercenary download list” button. Then, the registered mercenary list is displayed on the screen 63 of FIG. When the list is downloaded to the game machine, it can be downloaded by pressing a “download list” button. In addition, when the “Empty list” button is pressed on the screen 63 in FIG. 6A, the mercenary list can be emptied.

  The server of the present embodiment generates an import file (pack) including one or more mercenary data included in the mercenary list generated in the server and save data identification information in the same manner as the item download, and the game machine Alternatively, the terminal can download the generated import file.

  FIG. 7 is an example of an import file (packed file) generated by the server. The import file includes a key number, a user name, save data identification information, mercenary data, item data, and a checksum.

  The key number is, for example, a number for identifying a key for performing falsification or personal authentication. The user name is a user name determined at the time of initial registration when the player accesses the server. The user name can be a user name managed by the server of this embodiment.

  The save data identification information is save data identification information corresponding to a user ID managed by the server. That is, the save data identification information included in the import file uploaded from the game machine to the server. As the save data identification information, save data identification information can be generated based on unique identification information of the game machine (for example, a physical address of the game machine), a random number, or the like. The save data identification information may be allocated so as to be different for each save data, or may be allocated in association with a plurality of save data. For example, when one save data is branched and further save data is saved, the save data that is the branch source and the save data after the branch can be made the same save data identification information. Mercenary data is mercenary data of another player to be downloaded selected by the player. Item data is item data of an item selected by the player as illustrated in FIG. Note that the import file may include only one of mercenary data and item data, or may include both mercenary data and item data. The checksum is data for performing error detection during data transmission / reception.

  In the present embodiment, the server can encrypt the import file based on the key specified in the key number. In such a case, the game machine needs to perform processing for decrypting the encrypted import file.

  A method for importing an import file downloaded to a game machine or terminal into the game machine will be described with reference to FIG. The player selects save data for importing the downloaded file. For example, FIG. 8A is an example in which selected save data is displayed on a screen in a game machine. The player can determine save data to be imported by pressing a determination button.

  The game machine according to the present embodiment determines whether or not the save data identification information of the save data to be imported matches the save data identification information stored in the downloaded import file. In case you can import the import file. If it is determined that they do not match, the import file cannot be imported. Therefore, since the import file can be imported only in correspondence with specific save data, unauthorized use of the replicated data can be prevented. Note that importing means registering game data included in an import file in saved data. That is, it is registered in the save data as data that can be used in the game machine.

  A method for registering the downloaded game data in the save data will be described with reference to FIG. FIG. 9 shows an example of an image of the portable information storage medium of the game machine of the present embodiment. The portable information storage medium of the game machine of the present embodiment includes a save data storage area and a temporary data storage area used in the game of the present embodiment. The save data storage area can store one or a plurality of save data. The temporary data storage area stores import data (data included in the import file) downloaded from the server as temporary data. Then, it is determined whether or not the save data identification information included in the data in the temporary data area matches the save data identification information associated with the save data. If they match, the data is in the temporary data storage area. Game data can be registered in saved data. If they do not match, the game data is not registered in the save data, but is stored as it is in the temporary data storage area. The temporary data storage area may be overwritten successively with import data downloaded from the server. In this way, the memory area can be saved.

  Furthermore, when the game data (item data, mercenary data, etc.) included in the import file is registered in the save data, the game machine of this embodiment stores the file identification information included in the import file as a history in the storage unit. Remember. For example, a history table may be provided so that save data in which data included in the acquired import file is registered and file identification information of the import file are associated with each other and stored.

  In this way, when game data included in the same import file is registered again in the same save data, registration can be suspended. This is because if the player can register the item data and mercenary data included in the same import file as many times as possible, the game balance may not be maintained against the purpose of the game. Therefore, if it does not contradict the purpose of the game, subsequent registration may be permitted. For example, the number of file identification information histories is limited to a predetermined number, and when a certain number is exceeded, old file identification information is sequentially deleted. And when registering the data of the file corresponding to the file identification information already deleted from the history, it may be possible to register it in the save data. In addition, when registering the import file corresponding to the file identification information remaining in the history again in the save data, the registration of the game data included in the import file is not simply suspended but refused. May be.

  Next, a method for restricting the use of an item when a flag is set for each item in the present embodiment and the game machine according to the present embodiment exchanges an item with another game machine will be described.

  In the conventional method based on item exchange, there is a problem that an item is duplicated by exchanging the item, and the duplicated item is used as it is during the game. For example, when the game machine A transfers the item 1 to the opponent game machine B and acquires the item 2 from the game machine B, the item exchange is established. Here, the game machine A has only the item 2 at hand. However, if the item exchange is established without performing the transfer operation to the game machine A, the game machine B is in a state where both the item 1 and the item 2 are at hand. Therefore, duplication occurs by exchanging items. For example, the item 2 remains in the hands of both the game machine A and the game machine B, and duplication occurs.

  Therefore, the game machine according to the present embodiment employs a technique that prevents an item acquired in a specific acquisition format from being exchanged with another game machine. Specifically, a method is adopted in which items acquired via the network in the infrastructure mode are not displayed on the exchange list screen for exchanging items with other game machines. This is because items acquired in the infrastructure mode may be duplicated and scattered on the network. In other words, an item that can be acquired by the game machine via the network in the infrastructure mode, with the server serving as the source of the item, can be registered only in specific save data in association with the save data identification information described above. When a game is played based on saved data, duplication may occur due to illegal exchange with other game machines. Therefore, in the game machine of the present embodiment, items acquired via the network in the infrastructure mode are not displayed on the exchange list in order not to be exchanged with other game machines.

  FIG. 10A shows a setting example in the case where an item is displayed as an item to be transmitted to the opponent game machine when the item is exchanged with another game machine. For example, when displaying an item on the exchange list, the display flag is set to 1 (true). If the item is not displayed in the exchange list, the display flag is set to 0 (false). Then, as shown in FIG. 10B, only items whose display flag is set to 1 can be displayed as items to be transmitted. In other words, the item acquired via the network in the infrastructure mode sets the display flag to 0 (false). On the other hand, the display flag can be set to 1 (true) for data acquired outside the network in the infrastructure mode, that is, data acquired in the ad hoc mode or data acquired during the game, and displayed on the exchange list. Like that.

  Furthermore, the game machine according to the present embodiment employs a technique for changing the transaction value in order to limit the use value of the item acquired by the player character by an illegal copying act. That is, a transaction flag is set for each item, and the transaction value of the item acquired by exchanging is reduced. This is because, when an item is exchanged, one player may have both an item to be transferred to the opponent and an item received from the opponent, causing the items to proliferate.

  For example, FIG. 11A is an example in which a transaction flag is set for each item. 1 (true) is set when the transaction value is traded at a predetermined transaction value, and 0 (false) when the transaction value is reduced below the predetermined transaction value. Set. For example, FIG. 11 (B) shows an example of the transaction value of an item set in advance in the game of the present embodiment. FIG.11 (C) shows the transaction value at the time of reducing the transaction value of an item based on a transaction flag with respect to the item set in FIG.11 (B). During the game, the player character deals with an item whose transaction flag is 0 at the transaction value when the item is reduced. For example, referring to FIG. 11, since the transaction value of shoes and umbrella items is set to 1 (true), the shoe item trades with the transaction value 7000, and the umbrella item trades with the transaction value 1500. . However, since the hat and sword items have a transaction value of 0 (false), the hat item trades with a transaction value 1 that is lower than the predetermined transaction value 3000. Umbrella items are also traded with a transaction value of 1 that is less than a predetermined transaction value of 10,000.

  When the transaction value of an item for which the transaction flag is set to 0 (false) is decreased, the transaction value may be set to the minimum value of the monetary unit determined by the game, for example, 1. The transaction value may be decreased based on a certain decrease rate. For example, when the predetermined transaction value of the sword item is 10,000, and the decrease rate is 20%, the value may be decreased to 8000 value transaction value.

4). Processing of this embodiment Next, detailed processing examples of the game machine and the server program of this embodiment will be described with reference to the flowcharts of FIGS.

4.1 Export Processing FIG. 12 is a flowchart illustrating an example of processing in which the game machine of the network system according to the present embodiment exports save data and generates an export file.

  First, a user ID and a password are input based on player operation input (step S110). Next, it is determined whether or not there is an export folder (step S120). If there is an export folder (Yes in step S120), the process proceeds to step S150. If there is no export folder (No in step S120), the process proceeds to step S130. If creation of a folder is permitted based on the operation input of the player (Yes in step S130), a folder for export is created. If creation of the folder is not permitted (No in step S130), the process is terminated.

  Next, it is determined whether there is exportable save data (step S150). If there is save data that can be exported (Yes in step S150), the process proceeds to the next step. On the other hand, if there is no exportable save data (No in step S150), an error message is displayed (step S160) and the process is terminated. For example, “There is no save data that can be exported” is displayed.

  Next, it is determined whether or not save data has been selected based on the operation input of the player (step S170). If save data is selected (Yes in step S170), the process proceeds to the next step. On the other hand, when the save data is not selected based on the operation input of the player (for example, when the player performs an end operation) (No in step S170), the process ends.

  Next, it is determined whether or not the status data is to be exported based on the operation input of the player (step S180). When the status data is to be exported (Yes in step S180), a process of exporting and generating export data (or a file storing the export data) is performed (step S190). On the other hand, if it is determined not to export the status data based on the operation input of the player (No in step S180), it is determined again whether save data has been selected (step S170).

  Through the above processing, the player can store the exported export file in a portable information storage medium and upload it to a server via a terminal (for example, a user's personal computer).

  FIG. 13 is a flowchart showing an example of processing in which the game machine of the present embodiment exports save data and uploads the saved data to a server via the network in the infrastructure mode.

  First, it is determined whether there is any save data that can be exported (step S210). If there is save data that can be exported (Yes in step S210), the process proceeds to the next step. On the other hand, if there is no exportable save data (No in step S210), an error message is displayed (step S211), and the process is terminated. For example, “There is no save data that can be exported” is displayed.

  Next, a user ID and a password are input based on the player's operation input (step S212). Then, it is determined whether or not the game machine can be connected to the network (step S213). When it is possible to connect to the network (Yes in step S213), the process proceeds to the next step. When it is not possible to connect to the network (No in step S213), a connection impossible message is displayed (step S214). Exit. For example, a process of displaying “Cannot connect to network” on the screen is performed.

  Next, it is determined whether or not the user ID and password of the player can be authenticated on the server side (step S215). If the authentication is successful (Yes in step S215), the process proceeds to the next step. If the authentication cannot be performed, a non-authentication message is displayed (step S216), and the process ends.

  Next, it is determined whether save data to be exported is selected based on the operation input of the player (step S217). If save data is selected (Yes in step S217), the process proceeds to the next step. On the other hand, when the save data is not selected based on the operation input of the player (for example, when the player performs an end operation) (No in step S217), the process ends.

  Next, it is determined whether or not there is permission to export the save data based on the operation input of the player (step S218). When the save data is to be exported (Yes in step S218), a process of exporting and generating export data (or a file storing the export data) is performed (step S219), and the process proceeds to the next step. On the other hand, when it is determined that the save data is not to be exported based on the operation input by the player (No in step S218), it is determined again whether the save data has been selected (step S217).

  Next, it is determined whether or not the export data (or the file storing the export data) can be uploaded to the server (step S220). If uploading to the server is possible (Yes in step S220), the process ends. On the other hand, if uploading to the server is impossible (No in step S220), an export failure message is displayed (step S221) (for example, “Cannot export” is displayed), and save data is selected again. Is determined (step S217).

4.2 Save Data Identification Information Registration Process FIG. 14 is a flowchart showing an example of a server process when export data (export file) exported by a game machine is received in the network system of this embodiment.

  First, the server accepts exported export data (export file) (step S310). Next, the save data identification information included in the export data (export file) is registered in association with the accessing user ID (step S320). Then, the status data included in the export data (export file) is registered in association with the accessing user ID (step S330). This is the end of the process.

4.3 Import File Generation Processing FIG. 15 is a flowchart showing an example of processing of a server that generates an import file to be imported into game machine save data in the network system of the present embodiment.

  First, it is determined whether save data identification information associated with a user ID of a user accessing the server and status data associated with the user ID are registered in the server (step S410). If not registered in the server (No in step S410), the process ends. On the other hand, if it is registered in the server (Yes in step S410), the item (one or a plurality of items) in the item list and the save data identification information are included in association with the accessing user ID. An import file is generated (step S420). Next, the import file is encrypted (step S430). Next, an encrypted import file is transmitted in response to a download request from the game machine or terminal (step S440). This is the end of the process.

4.4 Import Process FIG. 16 is a flowchart illustrating an example of a process in which the game machine of the network system according to the present embodiment imports an import file including item data into save data of the game machine. Note that the import file has already been downloaded from the server and saved in the portable information storage medium of the game machine.

  First, the acquired import file is decrypted (step S510). Next, it is determined whether there is save data that can be imported (step S520). If there is save data that can be imported (Yes in step S520), the process proceeds to the next step. If there is no importable save data (No in step S520), an error message is displayed (step S530), and the process ends. For example, “No save data that can be imported” is displayed.

  Next, if there is save data (Yes in step S520), it is determined whether save data to be imported is selected based on the operation input of the player (step S540). If save data is selected (Yes in step S540), the process proceeds to the next step, and if save data is not selected (for example, if the player ends without selecting) (No in step S540), processing is performed. Exit.

  Next, based on the operation input of the player, it is determined whether or not overwriting of the item list of items in the save data of the game machine of the present embodiment has been permitted (step S550). If overwriting is permitted (Yes in step S550), the process proceeds to the next step. If overwriting is not permitted (No in step S550), the process returns to step S540 to determine again whether save data to be imported has been selected.

  Next, it is determined whether or not the save data identification information of the selected save data matches the save data identification information included in the acquired import file (step S560). If the save data identification information of the selected save data matches the save data identification information included in the acquired import file (Yes in step S560), the acquired import file data (item data) is saved. Import processing is performed (step S570), and the processing is terminated.

  On the other hand, if the save data identification information of the selected save data does not match the save data identification information included in the acquired import file (No in step S560), an error message is displayed (step S580), and the process Exit.

  FIG. 17 shows an example of processing in which the game machine of the network system of the present embodiment acquires an import file including mercenary data from a server via the network in the infrastructure mode, and registers the acquired import file in save data. It is a flowchart.

  First, a user ID and password are input based on the player's operation input (step S610). Next, it is determined whether or not the game machine can be connected to the network (step S611). If network connection is possible (Yes in step S611), the process proceeds to the next step. On the other hand, when the network connection is impossible (No in step S611), a connection impossible message is displayed (step S612), and the process is terminated.

  Next, it is determined whether or not the user ID and password are authenticated in the server to be connected (step S613). If authenticated (Yes in step S613), the server accesses the address where the server import file is stored (step S615). On the other hand, when it is not authenticated (No in step S613), an unauthenticated message is displayed (step S614).

  Next, it is determined whether or not there is a response to the save data identification information registration confirmation request (step S616). That is, it is determined whether or not there is a response to the confirmation request that the save data identification information associated with the accessing user ID requested by the game machine is registered. If there is a response that saved data identification information corresponding to the accessed user ID is registered (Yes in step S616), the process proceeds to the next step. On the other hand, if there is no response that the save data identification information corresponding to the accessed user ID is registered (No in step S616), an error message is displayed (step S617), and the process is terminated. For example, a message “Export saved data” is displayed.

  Next, the import file is downloaded (step S618), and the network is disconnected (step S619). Then, a process of decrypting the encrypted import file is performed (step S620).

  Next, it is determined whether there is save data that can be imported (step S621). If there is save data that can be imported (Yes in step S621), the process proceeds to the next step. On the other hand, if there is no save data that can be imported (No in step S621), an error message is displayed (step S622), and the process ends. For example, “No saved data” is displayed.

  Next, when there is save data (Yes in step S621), it is determined whether save data to be imported is selected based on the operation input of the player (step S623). If the save data is selected (Yes in step S623), the process proceeds to the next step. If the save data is not selected (for example, when the player ends without selecting) (No in step S623), the process is performed. Exit.

  Next, based on the operation input of the player, it is determined whether or not the overwrite of the mercenary data of the game of this embodiment has been permitted (step S624). When overwriting is permitted (Yes in step S624), the process proceeds to the next step. If overwriting is not permitted (No in step S624), the process returns to step S623 to determine again whether save data to be imported has been selected.

  Next, it is determined whether or not the save data identification information of the selected save data matches the save data identification information included in the acquired import file (step S625). If the save data identification information of the selected save data matches the save data identification information included in the acquired import file (Yes in step S625), the game data (merchant data) of the acquired import file is saved. A process of importing data is performed (step S626), and the process is terminated.

  On the other hand, if the save data identification information of the selected save data does not match the save data identification information included in the acquired import file (No in step S625), an error message is displayed (step S627), and the process is performed. Exit.

Perform processing, sound processing, etc. The coprocessor 902 assists the processing of the main processor 900, and executes matrix operation (vector operation) at high speed. For example, when a matrix calculation process is required for a physical simulation for moving or moving an object, a program operating on the main processor 900 instructs (requests) the process to the coprocessor 902.

  The geometry processor 904 performs geometry processing such as coordinate conversion, perspective conversion, light source calculation, and curved surface generation based on an instruction from a program operating on the main processor 900, and executes matrix calculation at high speed. The data decompression processor 906 performs decoding processing of compressed image data and sound data, and accelerates the decoding processing of the main processor 900. Thereby, a moving image compressed by the MPEG method or the like can be displayed on the opening screen or the game screen.

  The drawing processor 910 executes drawing (rendering) processing of an object composed of primitive surfaces such as polygons and curved surfaces. When drawing an object, the main processor 900 uses the DMA controller 970 to pass the drawing data to the drawing processor 910 and, if necessary, transfers the texture to the texture storage unit 924. Then, the drawing processor 910 draws the object in the frame buffer 922 while performing hidden surface removal using a Z buffer or the like based on the drawing data and texture. The drawing processor 910 also performs α blending (translucent processing), depth cueing, mip mapping, fog processing, bilinear filtering, trilinear filtering, anti-aliasing, shading processing, and the like. When a programmable shader such as a vertex shader or a pixel shader is installed, the vertex data is created / changed (updated) and the drawing color of a pixel (or fragment) is determined according to the shader program. When an image for one frame is written in the frame buffer 922, the image is displayed on the display 912.

  The sound processor 930 includes a multi-channel ADPCM sound source and the like, generates game sounds such as BGM, sound effects, and sounds, and outputs them through the speaker 932. Data from the game controller 942 and the memory card 944 is input via the serial interface 940.

  The ROM 950 stores system programs and the like. In the case of an arcade game system, the ROM 950 functions as an information storage medium, and various programs are stored in the ROM 950. A hard disk may be used instead of the ROM 950. The RAM 960 is a work area for various processors. The DMA controller 970 controls DMA transfer between the processor and the memory. The DVD drive 980 (may be a CD drive) accesses a DVD 982 (may be a CD) in which programs, image data, sound data, and the like are stored. The communication interface 990 performs data transfer with the outside via a network (communication line, high-speed serial bus).
