Abstract: A video game system includes a video game machine and a controller connected thereto, wherein the game machine is further connected with a display device. A video-game memory medium, detachably attached to the game machine, generates image data for displaying a player object, a plurality of courses, and objects other than the player object. A player chooses a course of play by operating the controller. A score-giving condition is detected according to a relation of the player object to another object. Depending on the detection, a first score is counted for the course. When the player object comes under a condition satisfying a course clear, the first score is memorized in a score-register area of a RAM. If the user chooses to play a same course, an initial value is written to the score-register area.

Abstract: A video game apparatus includes a reality coprocessor. The reality coprocessor performs a conversion process on image data to display a player object or non-player object according to image data transferred from an external ROM to a RAM, and supplies the image signal through the display. The reality coprocessor detects whether or not there exists a non-player object at around the player object on the display in response to an operation of a Z button. If a non-player object is detected, the reality coprocessor selects the non-player object as an attention non-player object. At this time, the hypothetical camera is changed in position and photographing direction such that photographing can be made for the player object directly facing the non-player object.

Abstract: A video game system includes a game machine and a memory medium. The game machine is connected with a controller to be operated by a player and a display device for displaying game images. The memory medium generates player object image data and influencing object image data, as well as generates message data. The message data is a message to teach the player how to operate the controller. A player object and an influencing object are displayed on the display device. Also, the display device displays a message of how to operate the controller.

Abstract: A cyanoiminoquinoxaline derivative of the formula (II) is useful as a preventive or therapeutic agent for diseases due to hyperexcitation of glutamate receptors. (wherein, X and Y each is independently O or NCN, provided that at least one of X and Y is NCN; R1, R2, R3, and R4 each is independently hydrogen, halogen, nitro, optionally substituted heterocyclic group etc.; R5 is hydrogen etc.; R1 and R2, R2 and R3, R3 and R4, and R4 and R5, each taken together with the adjacent atoms may form a carbocycle which may be substituted or may contain a heteroatom(s).

Abstract: When any of push-button switches on a handheld controller is pressed in a sound input mode, a video game machine generates and temporarily stores frequency data of a tone corresponding to the depressed switch. When a joystick on the controller is tilted to a predetermined direction, the video game machine changes the generated frequency data according to the amount of tilt of the joystick. It is therefore possible to input various sounds in tone using a limited number of switches. The frequency data stored in the video game machine is read later to be converted into audio signals, and outputted from a speaker incorporated in a CRT display. When a melody based on the inputted sound coincides with a predetermined melody set, the video game machine makes various changes in the progress of the game. For example, a hero character can be warped to a position that is different from the present position, or provided with various items.

Abstract: A video game apparatus includes a CPU. The CPU determines straight lines respectively connecting between the player object and a North Pole, target and marker, and determines respective directions of a direction pointing mark, target pointing mark and marker pointing mark to point direction parallel to the straight lines. The player object or other objects are combined with these pointing marks, and displayed on a display.

Abstract: A video game apparatus includes an external ROM. This external ROM is previously memorized with player object data, basic shadow object data and light object data. A direction in which a shadow is thrown is determined according to the player object data and the light object data, to thereby determine a length of each leg of the player object. Based on the length of the leg and the height of the light, a length of the shadow is determined. Based on the height of each leg, a depth of the shadow is determined. A shape of a displaying shadow object is determined from a state of a ground object to which the shadow is thrown.
