Abstract: An object of the present invention is to, when execution of a program is started, in a case where a memory region used by the program when the execution of the program was stopped is usable, enable the past execution conditions of the program to be reproduced without reading in data disposed in the memory region used by the program, which data was stored when the execution of the program was stopped. When the execution of the program is stopped, a stop and end managing section (52) performs control to store at least a part of the data disposed in the memory region used by the program in association with the program while retaining the data.

A display processing unit (46) processes menu screen display and content reproduction. A menu unit (48) generates image data on a menu screen where a plurality of function icons and a plurality of media icons are arranged two-dimensionally according to a user function.

Abstract: A message data acquisition unit acquires message data including a message and additional information. An event ID acquisition unit acquires, when a condition fulfillment detection unit determines that a condition is fulfilled, condition identification information identifying the fulfilled playing condition in the game. A display information generation unit displays a message in the message data including the additional information corresponding to the acquired condition identification information, in a game screen displayed on a display device.

Abstract: A processor is allowed to receive a request for downloading save data of a game, to check, in reference to a list containing an identifier that identifies the save data, an attribute indicating whether download of the save data is restricted, and a next downloadable time in association with one another, whether the save data has the attribute that indicates the download is restricted, to check, when the save data has the attribute that indicates the download is restricted, whether the request for downloading the save data was received at or after the time at which the save data becomes downloadable again, and to reject the request for downloading the save data and notify a user the next downloadable time when the request for downloading the save data was received before the time at which the save data becomes downloadable again.

Abstract: A game device includes: a display device; a rear touch panel provided on the other side of a surface on which the display device is mounted; an activation control unit operative, when the rear touch panel detects an operation of bringing an input means into contact with the rear touch panel and moving the input means in a predetermined direction, to activate a function determined in accordance with the direction; and a screen image managing unit operative to display a screen image displayed by the function activated by the activation control unit on the display device so that the screen image slides from an edge of the screen of the display device in the direction.

Abstract: In an information processing apparatus, a file system manages files in a storage unit. Upon receipt of a boot instruction, a process boot unit starts an application. Once the application is started, a path acquisition unit acquires the path to an application file and the path to a patch file in the storage unit. When there is contents with the same name in both the application file and the patch file, a path switching unit switches the path directed to the contents of the application file to the path directed to the contents of the patch file.

Abstract: In an information processing apparatus, a file system manages files in a storage unit. Upon receipt of a boot instruction, a process boot unit starts an application. Once the application is started, a path acquisition unit acquires the path to an application file in the storage unit. A mount unit associates the path acquired by the path acquisition unit with a predetermined virtual mount point. A processor specifies the predetermined mount point and then accesses the file.
