Abstract: To provide an emulator capable of targeting a device capable of accepting connection of an expansion device for expanding a controller connection port to a plurality of controller connection ports. The emulator, targeting a device having at least one controller connection port and capable of accepting connection of an expansion device for expanding the controller connection port to a plurality of controller connection ports so as to accept connection of a plurality of controllers, emulates operation of the targeted device. The emulator assigns port identification information to each of controllers connected via wire or radio, the port identification information indicating to which of a controller connection port of the targeted device and the controller connection ports of the expansion device connected to the device the controller is assumed to be connected. The assigned port identification information is provided to a process for receiving an operation carried out on the controller.

Abstract: A compatibility adapter configured for connection to an external connection terminal of a new-generation game device is provided. An old-generation processor unit is a processor unit compatible with the processing function of an old-generation game device. When it is determined that the type of a recording medium storing application software is for the old-generation game device, a hub receives data, which has been input to the new-generation game device, from the new-generation game device via the external connection interface. Data extracted from a received packet is supplied to the old-generation processor unit and processed accordingly. The hub supplies the processed data to the new-generation game device via the external connection interface.

Abstract: An information processing device to solve the above-mentioned disadvantage according to the present invention comprises: information receipt part to receive a digital information from an external information record medium; first judgment part to judge whether the external information record medium is a medium which is readable and writable; second judgment part which judges whether a predetermined security processing is performed to the digital information to be received; and control part to control the information receipt part to refuse a receipt of the digital information which is judged that the medium is readable and writable by the first judgment part and a security processing is not performed by the second judgment part.

Abstract: An entertainment apparatus includes a storage unit that stores outside a kernel a device driver for a peripheral device. To make the peripheral device operable, a CPU causes an I/O processor to execute the device driver using a remote procedure call. Data is transferred between the peripheral device and the CPU through a direct memory access using a communication protocol that is commonly used in the apparatus.
