Why play 'Super Smash Bros. Ultimate' with a Joy-Con when GameCube controllers work great with the Nintendo Switch?

Using JoyToKey you can map keyboard and mouse inputs to any type of controller. It also supports profiles, allowing you to create and store different configurations.

Games aren't the same without a gamepad under your thumbs. Play on your PC with your Xbox 360, PS3, or PS2 controller--and other game devices.
