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 22 for controlling the sound presentation by setting an operation parameter necessary for a control register of the sound synthesis circuit 42; and an LED driver for performing a lamp presentation by appropriately lighting and driving a plurality of N groups of lamp groups formed into groups. The presentation control part 22 includes: first means for setting a first operation parameter in a control register so that the sound synthesis circuit 42 generates sound data; and second means for setting a second operation parameter in the control register so that the sound volume of the four speakers corresponds to the lamp presentation with respect to the sound data reproduced by the sound synthesis circuit 42. |
