PROBLEM TO BE SOLVED: To provide a game machine enabling a novel and powerful presentation operation.SOLUTION: The game machine includes: four speakers for performing a sound presentation by receiving an output from a sound synthesis circuit 42; a presentation control part for controlling the sound presentation by setting a necessary operation parameter in a control register of the sound synthesis circuit 42; and an LED driver for performing a lamp presentation by appropriately lighting and driving grouped a plurality of N groups of a lamp group. The presentation control part is composed of first means for setting a first operation parameter in the control register so that the sound synthesis circuit 42 may generate sound data, and second means for setting a second operation parameter in the control register so that sound volume of the four speakers may support the lamp presentation with respect to the sound data reproduced by the sound synthesis circuit 42.SELECTED DRAWING: Figure 7 |
