Description

In order to achieve the above object, the gaming machine according to the present invention provides image control means having a CPU circuit for issuing a display list specifying a display screen of a display device ; image generating means having a drawing circuit for executing a drawing operation to generate predetermined image data based on the set values and the display list in a predetermined RW memory; and a CG memory , wherein the RW memory is a plurality of memories including a special area and a reserved area by setting a setting value required by the CPU circuit in any of the built-in registers. Securing processing for partitioning into areas and securing a predetermined two-dimensional space in a storage area other than the special area is executed prior to the drawing operation of the drawing circuit, and the display list includes the drawing of the drawing circuit. First information specifying a base point position of a rectangular space within the predetermined two-dimensional space, which functions in response to an action, and defining the drawing content to be reflected in the rectangular space among the drawing content based on the display list. 2nd information specifying the two corner points of the diagonal position of the rectangular drawing range, and 3rd information specifying the storage position and data size of the basic data when the basic data is to be acquired. By associating the rectangular drawing range with the rectangular space of the RW memory by means of the first information and the second information, the drawing contents based on the display list are reflected in the rectangular space. 3 The basic data acquired based on the information is configured to be acquired in the special area and then developed in the reserved area, and the image generating means extracts the basic data from the CPU circuit in units of predetermined acquired bits. a data transfer circuit having a transfer port for receiving configuration data of a display list and a FIFO buffer having a FIFO structure for accumulating the configuration data received by the transfer port; determination means for determining whether the data transfer circuit is functioning normally based on one or more status registers built in the device; canceling means for setting an initialization instruction in one or a plurality of registers incorporated in the image generating means to stop issuing the display list when the display list is not normalized.
