Game machine

Abstract

To provide a game machine highly efficiently using a capacity of a main ROM by executing prescribed processing without adding new processing when referring to information input from an input port to execute the prescribed processing.SOLUTION: A game machine includes setting value operation means, door opening / closing detection means, setting change processing means capable of changing a setting value, and input port processing means for executing processing of reading information from an input port. The input port processing means reads setting operation information and door opening / closing information, where second storage means has a prescribed area for storing the setting operation information and the door opening / closing information. The input port processing means stores the setting operation information read from a prescribed input port in the prescribed area, and the door opening / closing information read from a specific input port in the prescribed area, The setting change processing means refers to the setting operation information and the door opening / closing information stored in the predetermined area and determines the end of the processing by the setting change processing means.SELECTED DRAWING: Figure 433

Claims

【Claim 1】 control means for performing arithmetic processing for controlling the progress of the game; first storage means in which information necessary for the execution of the arithmetic processing by the control means is stored; second storage means in which information necessary for the execution of the arithmetic processing by the control means is stored; setting value operation means for changing or confirming a setting value; door opening / closing detection means for detecting the opening and closing of the front door; setting change processing means capable of executing the change of the setting value; input port processing means for performing a process of reading information from an input port within an interrupt process executed based on a timer interrupt occurring at a fixed cycle, comprising: the input port processing means reads setting operation information indicating the state of the setting value operation means and door opening / closing information indicating the state of the door opening / closing detection means; the setting change processing means determines the end of the process by the setting change processing means based on the read setting operation information and door opening / closing information; the second storage means has a predetermined area for storing the setting operation information and the door opening / closing information; the input port processing means stores the setting operation information included in the input information read from a predetermined input port in the predetermined area, and stores the door opening / closing information included in the input information read from a specific input port in the predetermined area; the setting change processing means determines the end of the process by the setting change processing means with reference to the setting operation information and the door opening / closing information stored in the predetermined area; the second storage means has a plurality of state information storage areas for storing a plurality of types of information regarding the state of the input port, provided for each type of input port; the state information storage area includes at least a first state storage area for storing information indicating the state of the current input port, a second state storage area for storing information indicating the state of the input port at the previous interrupt process, and a third state storage area for storing information regarding the change mode of the state of the current input port; the input port processing means generates information regarding the change mode of the state of the current input port based on the information indicating the state of the current input port, the information indicating the state of the input port at the previous interrupt process, and the information indicating the state of the input port at the penultimate interrupt process; A gaming machine characterized by the above.
