Abstract: A forward direction line is set on a course, in a virtual game world, on which a player object is allowed to move. An advancing direction at a current position of the player object is determined based on the forward direction line. The advancing direction is determined as a direction in which the player object advances so as to control a movement of a player character in accordance with an acceleration instruction, and a leftward-rightward movement instruction from a player. Consequently, it is possible to assist the player in controlling a direction in which an object operated by the player moves.

Abstract: A game apparatus includes a touch panel on which at least two pointing positions are simultaneously detectable. In response to an operation of the touch panel by a player, coordinates values of the detected two points are detected, and at least one of a distance between the two points and an angle of the line connecting the two points is calculated. Furthermore, change amounts of the distance and angle between the two points are calculated. A movement parameter such as a travel speed and a turning angle is set on the basis of at least one of the calculated distance and angle, and the movement of the character such as travel and turning is controlled on the basis of the movement parameter. In addition, when a pointing state of the two points is changed, the movement parameter is changed on the basis of a change amount, and the movement of the character is controlled on the basis of the movement parameter.

Abstract: Sound generated by handclaps of a player is converted into an electric signal by a microphone, and the electric signal is inputted to a game apparatus. When a jump instruction is inputted, a player character jumps. However, the character jumps in accordance with the handclaps of the player only when the character is positioned on a jump ramp set in a virtual game world. In a case where ambient noise is inputted through the microphone when the character is not positioned on the jump ramp, the player character does not jump, but performs a provocative action. The provocative action does not exert any influence on a movement of the player character. Thus, in an action game for causing the player character to perform a predetermined action in accordance with a sound input, it becomes possible to prevent the player character from performing an action which is not intended by the player, even if the sound input is mistakenly detected.

Abstract: Each time a player hits either one of right and left strike surfaces of a conga controller, it is determined whether: the right strike surface has been hit continuously; the left strike surface has been hit continuously; or the right strike surface and the left strike surface have been hit alternately. When the right strike surface has been hit continuously, a character in a game world is caused to move rightward. When the left strike surface has been hit continuously, the character is caused to move leftward. When the right strike surface and the left strike surface have been hit alternately, the character is caused to accelerate. Based on the above, a game program and a game apparatus, which are capable of giving various action instructions to the character of the virtual game world by using continuous inputs by a plurality of switches, can be provided.

Abstract: In a game processor GP that enable a player to play a plurality of games interrelated to each other, flash memory 12 stores a plurality of game programs PG interrelated to each other. SRAM 13 readably and writably stores backup data DG representing the progress of each of games A, B, and C. The player selects one of the game programs PG through a controller 70 to start game play. A deciding unit (CPU) 61 decides whether there is backup data DG for any game related to the game specific to the selected game. Based on a decision as to the backup data DG, a game program changer changes part of the game program PG.

Abstract: A videographics/video game fabricating system includes a multiprocessor based game processor console which includes a main central processing unit (CPU) which controls editing operations and operating system task execution and a game CPU for executing the model video game which is loaded into a pluggable RAM cartridge. The model video game provides a starting point from which a user can readily create an original video game including desired aspects of the model software. The system permits a user to modify any of the game's moving objects, background screens, music or sound effects. The main CPU and game CPU cooperate in the game execution and editorial process such that an editing screen generated by the main CPU is superimposed on a game screen generated by the program executing CPU.
