NMJ

NMJ is a Smashcentric, 3rd party Switch accessory that’s poised to change the way we play the game forever. It’s a small computer that sits between your GameCube adapter and Nintendo Switch. You will experience the game at unprecedented speeds, both at home and online. NMJ also uses a “game changing” calibration technique to make nearly every controller work precisely and reliably. And yes, NMJ will make your old controllers like new. NMJ offers many other features such as input mapping for Smash, an advanced controller visualizer, a GameCube controller simulator, and a Training Mode (The Lab). All of this with no hacking. NMJ will make every player a better player, no more excuses. No More Johns.
