  • Patent number: 5963218
    Abstract: A method is provided for displaying a video game character traversing a video game playfield, for use with a system which includes a video screen display, a user-controlled graphics controller and digital memory; wherein the video game character follows a path within the playfield, the method comprising the steps of: storing multiple collision blocks that define respective path segments; dividing the playfield into multiple path blocks that comprise the path; storing character collision-type information; storing references from individual path blocks to individual collision blocks; displaying character movement through the playfield from path block to path block along the path in response to user input to the graphics controller; controlling the display of character movement by causing the character image to follow a path defined by the path segments of individual collision blocks; and changing the stored character collision-type information when the character path passes a prescribed location on the playfiel

  • Patent number: 5941775
    Abstract: The present invention aims at providing a data processing system which can realize a variety of process. A secondary memory cassette 31 includes a connector 32 which can be connected to both a primary memory cassette 21 or a processing device body, and address transfer circuit 39 which judges whether the connector has been connected to the primary memory cassette 21 based upon the connection state of the connector and outputs an address transfer signal, and a memory 38 which outputs data corresponding to the address transfer signal and the address signal supplied from connector 32. The primary memory cassette 21 includes a mask ROM 28, a connector 22 for connection with the processing device body, and a connector 24 which can be connected with the secondary memory cassette 31. A predetermined pin of connector 24 is connected to a ground.

  • Patent number: 5935003
    Abstract: Videogame systems and methods are provided to enhance the capability of the videogame system controller and data storage to provide graphic character element storage and processing. A display list technology utilizes an intentionally generated, location-specific vertical interrupt to implement a routine to modify or to alter existing graphical character elements. A second technique involves the definition of a small portion of the graphics map which is displayed differently than the balance of the graphics map because the stored priority bit is expressed in the defined area, but suppressed and replaced in all other areas. The third technique employs a virtual character element library to map the character elements appearing on the display, and recognizes available space within the video random access memory character element storage to provide a dynamic memory space.

  • Patent number: 5781180
    Abstract: A convertible peripheral input device comprises a control pad and a multiaxis input device selectably mounted on the edges of the control pad so that the multiaxis input device can be positioned for right-handed use or left-handed use according to the user's preference. The multiaxis input device can be rotated from one position to another by the use of a hinge mechanism with two points of rotation: one for rotation of the multiaxis input device 180 degrees relative to the hinge mechanism and the second point of rotation allowing the hinge mechanism to be rotated 180 degrees relative to the control pad bottom surface. The rotatable hinge mechanism may be used with videogame control pads and joysticks as well as keyboards with mouse controllers.

  • Patent number: 5523886
    Abstract: A stereoscopic video display device includes a left and a right video display for viewing by respectively the left and right eye of a viewer, a video driver circuit which alternates between driving the left video display and driving the right video display, and a view control circuit for providing a left-right signal which indicates which video display is currently displaying the video signal. A video signal source, such as a computer or a video game console, receives the left-right signal and provides a standard video signal. The stereoscopic display is usable with a source that provides a video signal that represents a left or right view according to the left-right signal, or with a source that ignores the left-right signal and provides a monoscopic video signal. The stereoscopic display is operable in both a stereo and a mono mode so that a user can select either monoscopic or stereoscopic video when the source is capable of providing stereoscopic views.
