The CAT-R is a game development console produced by Nintendo for the Wii U. The console itself looks like a regular Wii U with the exception of the front panel being green. The Gamepad itself is also green on the back. The console has a Bluetooth connector and two DRC (Wii U Gamepad) connectors on the backside of the main unit. The unit is also able to switch between a wired and wireless mode for the BT and Gamepad connections. This version of the development unit is very common, as it was easier to access by the public, and many indie developers/aspiring developers picked this version up.
