Abstract: A video game device in which a competition is developed between a main character and an enemy character by giving instructions to move the main character operated by an operation unit in a game space displayed on a display screen. The video game device comprises: a character processing unit for displaying an area mark belonging to one of the main character and the enemy character and having a specified size, a judging unit for judging whether the other character has continued to be inside the area mark for a predetermined time, and a game result output unit for obtaining a result of the competition when the other character continued to be inside the area mark for the predetermined time.

Abstract: A background-sound switching method and apparatus is provided for switching of background-music data. A partitioning code represents an end position of a phrase of background sounds outputted through a speaker. A switching instruction device outputs a switching-instruction signal which causes switching from the background-sound data being outputted to a D/A converter to other background-sound data. Following output of the switching-instruction signal, a data-number controller stores in RAM a data number which defines a next background-sound data to be outputted to the D/A converter. A code detector detects the partitioning code of the background-sound data being outputted. At each time the partitioning code is detected, a switching controller determines whether or not the data number is stored in the RAM and, if the data number is stored in the RAM, the background-sound data being outputted is switched to the other background-sound data defined by the data number.

Abstract: Disclosed is a game system which matches a player's tastes. In a game system operating in time with music, it is possible to select an edit mode for editing timing data which define timings of operations. In the edit mode, an edit window having a predetermined display range is displayed on a screen of a display device in correspondence with information representing a position in a tune. Images in the edit window are scrolled so that the position of a target to be edited set inside the edit window moves forward and backward through the tune. When an operation is performed to provide marks, timing data for showing an operation timing of a control member provided in correspondence with the operation is provided at the position of the edit object in the edit window, and in addition, the timing data during editing is updated so that the position in the tune corresponding to the position of the edit object is defined as a operation timing.
