Publication number: 20220233950Abstract: The arcade-style video game controller is a video game controller that has the outward appearance resembling that of an arcade controller, and is attuned to perform for video games, specifically shooting games. The controller has many ports to connect it to the gaming computer or console, and to provide ports to the user for external hardware and an audio port. Two important distinguishing features of the arcade-style video game controller are its maintainability and customizability. The box can be easily maintained since the top is a hinged lid, that can open up for the user to clean the insides of the controller or replace parts as necessarily. Furthermore, the box can be easily customized by the same lid, which is comprised of several layers whereby the user may insert interchangeable artwork to be displayed as the controller's top face.Type: ApplicationFiled: January 25, 2021Publication date: July 28, 2022Inventor: Adam Larson
