The Start button (also called the Start/Pause button on the GameCube controller) refers to the small, gray button in the center of a GameCube controller, or the small, red button in the center of a Nintendo 64 controller, or the small, rectangular pad to the bottom right of the touch screen of a Nintendo 3DS. In addition, the plus button on the Classic Controller, Wii U GamePad, and Wii U Pro Controller can alternatively be called Start.
During a match, players may repeatedly press the Start/Pause or + button to distract the other players, to disrupt their combo timing, or otherwise mock other players after a KO or win, though this practice is considered very rude. To prevent this occurrence, pausing may be turned off.
The Start/Pause or + Buttons are used to pause most games as well as select features in the menus. The button is also used to change the background in the games' Trophy Galleries.
