The Smash Box is a controller designed by Hit Box founder Dustin Huffer. The design of the controller is reminiscent of a traditional fightstick used by other fighting games, with one notable exception: the lack of a joystick. In an attempt to address precision and health issues associated with the joystick, the Smash Box instead uses analog buttons.
The Smash Box received notable praise and financial backing, but ran into controversy over its tournament legality; several smashers accused the controller of potentially providing an unfair advantage for those who were able to use it. As a result of this uncertainty, GENESIS 4 permitted players to use the Smash Box controller in an attempt to test the controller.
