A method for producing a mapping tool, a video game system for a stand-alone computer having the mapping tool and operation method thereof is disclosed. The mapping tool is created by means of linking a remote motion signal generated from a remote device which is operated by user with an input source signal from a conventional input source motion mapping table. User may operate the video game system for the stand-alone computer through the mapping tool. The present invention employs the mapping tool to replace conventional input source motion mapping table, thereby providing natural ergonomic and consistent usage of existing PC games or games for stand-alone computer having the input source motion mapping table.
