An example display system for playing a video game includes a hand-holdable housing; a liquid crystal display; one or more input devices; a first boot ROM storing code that is executed if a video game program for the video game has a first specification; and a second boot ROM storing code that is executed if a video game program for the video game has a second specification.

Portable video game system

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.

Video game display system

Memory for video game system and emulator using the memory

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.

Hand-held display system and display method and storage medium therefor

An example image display apparatus includes processing circuitry such as a communication processor and a game processor. The processing circuitry continuously processes a communication-related function and selectively processes a game-related function. When the game function is in an off-state, binary image data and color image data for the communication-related function are written to a first memory and to a second memory, respectively. When the game function is set to an on-state, color image data for the game-related function is written to the second frame memory instead of the color image data for the communication-related function. A display includes a composite image based on the binary image data stored in the first memory and the color image data stored in the second memory.

Image processing apparatus and display control method

An electronic apparatus includes a phone CPU and a game CPU. When a * key is operated during execution of a game, the phone CPU sets a specified bit of a game key register to '1'. The phone CPU is set '1' into the specified bit when there is an incoming call of a phone during the execution of the game. The game CPU pauses the game being in execution when the specified bit is renewed to &#x201c;1&#x201d; and restores the specified bit from &#x201c;1&#x201d; to &#x201c;0&#x201d;. When the * key is operated in a state the game is interrupted, the phone CPU sets &#x201c;1&#x201d; into the specified bit. The game CPU restarts the game by canceling the pause.

Electronic apparatus having game and telephone functions

An information processing device such as a game machine is selectively connectable to different peripheral devices such as memory devices. These 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.

Gaming machine that is usable with different game cartridge types

Hand-held electronic game machine

To a CPU in a portable game machine , a temperature detector and a voltage detector are connected. The temperature detector detects an operating temperature of an LCD , and the voltage detector detects a power supply voltage supplied by the LCD . Following a program stored in on-chip ROM , the CPU calculates a driving voltage for the LCD based on the detected temperature and voltage. At the same time, the CPU selects, from among a plurality of character data items which are previously provided, at least one character data item and writes the selected data item into display RAM . The detected temperature and voltage each correspond to the character's age and action. As a result, correct colors can be displayed even in a case where the LCD is adopting an Electrically Controlled Birefringence method. Further the character selected based on the temperature and voltage is displayed on the LCD

Portable game machine

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.

Portable color display game machine and storage medium for the same

In a portable game machine 10, formed on the upper portion of a body portion 20 is a camera portion 30. An image display device 22 is arranged on one main surpace of the body portion 20, and operating switches 23, 24, etc., are arranged on other areas. The camera portion 30 is rotatably supported to the body portion 20, and a user can shoot images in both forward and backward directions when viewed from the user. Preferably, the camera portion 30 is supported having a prescribed angle to the body portion 20 so that its focal axis tilts with respect to main surfaces of the body portion 20.

Portable game machine and portable game machine cartridge

A memory cartridge which may be loaded in an attachable/detachable manner to a data processing apparatus, such as a hand-held electronic game machine having a central processing unit (CPU), includes logic control circuitry, a program read only memory (ROM), a bank changing circuit, and external random access memory (RAM). The external RAM is backed-up by a battery. First key data and second key data are initially stored in the program ROM. After a power source of the data processing apparatus is turned-on and a power source voltage reaches a predetermined value, a reset signal is provided to the memory cartridge to enable circuits on the memory cartridge. When the first key data is read from the program ROM and the reset signal is detected, the external RAM may be accessed by the CPU to read and write information from/into the external RAM. When the second key data is read from the program ROM, the CPU is inhibited from such access to the external RAM.

Memory cartridge including a key detector for inhibiting memory access

A communication adapter which is used with a plurality of game sets for transmitting and receiving data related to the game states of the game sets. Each game set including a serial interface and a buffer memory for temporarily storing transmit/receive data. The adapter including: a housing; a connection terminal for each game set; data input, data output and clock output ports, a clock signal generator, format converter and transmit/receive storage means. The clock signal generating means applies the same clock signal used for data communication with the game sets to each clock output port so that data to be transmitted to each game set and data received from each game set is synchronized with the clock signal whereby reliable communication is obtained with two or more game sets without the use of modems.

Communication adaptor for game set

An X-axis counter (101) and a Y-axis counter (102) detect velocities of the movement of a mouse in X-axis and Y-axis directions, respectively. A comparator (103) detects which of the velocities of the movement of the mouse in the X-axis and Y-axis directions is higher. An X-axis displacement amount correction data ROM (106) and a Y-axis displacement amount correction data ROM (107) correct a detection result by the X-axis counter (101) and a detection result by the Y-axis counter (102) with the same correction rate based upon detection results by the comparator (103) to output displacements in the X-axis and Y-axis directions.
