<P>PROBLEM TO BE SOLVED: To provide game machine monitoring the condition of a power source when power supply is started, which is configured such that when the power source has an abnormal condition, the condition of the power source is monitored again after a predetermined period passes without increasing the program capacity and cost. <P>SOLUTION: A CPU 56 confirms a power off signal in main processing, and confirms the power off signal again after a predetermined time (time-out time) passes, when the power off signal is not off. A VDP 109 executes an alpha test or alpha blending using alpha values set in pixels for image data, and a decoration symbol images are gradually and stepwisely changed during variable display. Further, based on a command from a symbol control CPU 101a, the VDP 109 previously stores image data of a component image frequently used from a CGROM 83 to a VRAM 84 when the VDP is actuated; and the image data is read out from the VRAM 84 for rendering when display is updated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
