Game system and computer-readable memory medium

摘要

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.
