Abstract: A hand-held electronic device (10) includes an upper housing (21) and a lower housing (11) which are foldable. An upper LCD (22) capable of displaying an image which is stereoscopically visible with naked eyes is provided on an inner side surface of the upper housing (21).

Abstract: A portable game system includes two display screens, at least one of which is touch-sensitive. A memory card or other device is selectively connectable to the portable game system via in insertable connection port.

Abstract: A semiconductor memory includes a memory control section and a memory core section. A command judgment circuit in the memory control section changes the operating mode of the semiconductor memory in response to a command sent from a controller of an information processing apparatus. In a first mode, a decryption process is performed in a command decryption circuit, and data outputted from the memory core section is not scrambled. In a second mode, the decryption process is not performed in the command decryption circuit, and the command outputted from the memory core section is scrambled.

Abstract: A hand-held display system for playing video games includes a housing grippable by a user's hands, a liquid crystal display viewable by the user gripping the housing, input devices operable by the user when the user grips the housing and a connector for, in use, operatively connecting to portable storage media storing video game programs for the video games. First processing circuitry processes video game programs having a first program specification and second processing circuitry processes video game programs having a second program specification.

Abstract: A storage medium includes an ID registration area for storing therein a main body ID which is an ID unique to an information processing apparatus. The information processing apparatus has the main body ID stored therein. The information processing apparatus includes copying means for, when the storage medium is attached thereto, copying a program stored in the storage medium thereinto in the case where the main body ID has not yet been registered. When the copy is made, the main body ID is stored into the ID registration area of the storage medium. The information processing apparatus also includes execution program selecting means for selecting, from the copied program and from the program stored in the storage medium, a program to be executed.

Abstract: A colorizing method for a display system involves accessing a memory storing monochrome display data for a video game program. User input designates one of a plurality of different color palettes and a color display is generated based on the monochrome display data and the designated palette.

Abstract: An information processing device such as a game machine is selectively connectable to different peripheral devices such as memory devices. The peripheral devices may be provided with characteristics for distinguishing one from another. The information processing device carries out operations based on the peripheral device connected thereto The information processing device may also access memories which store data having different data widths.

Abstract: A portable color display game machine includes a game cartridge type determining circuit configured to determine whether a color game cartridge storing color data for a game or a monochrome game cartridge storing monochrome data for a game is attached to the color display game machine. Color display generating circuitry is configured to generate a color game display based on the color data when the color game cartridge is attached to the color display game machine, and to generate a color game display based on the monochrome data when the monochrome game cartridge is attached to the color display game machine.

Abstract: In an information processing device 30 having engaged in a detachable manner with, for processing, via an external bus 37, 47 in a second data width, a first game cartridge 20 housing first memory 22 in a first data width, or a second game cartridge 40 being partially different in shape from the first game cartridge 20 and housing second memory 42 in the second data width, a shape discriminator 35 discriminates between the first and second game cartridges 20, 40, and a central processing unit accesses the second memory 42 in a multiplex bus mode and the first memory 22 in a normal mode.
