The Nintendo Switch console recently received a new system update, which added support for the Wii U Pokkén Pro Pad. The controller along with its excellent D-pad, which was designed specifically for Pokkén Tournament, can now be used with any Nintendo Switch game. The gamepad is also compatible with an adapter in tabletop mode on Nintendo Switch, as demonstrated in the video below:
