No Contest screen
A no contest screen happens whenever a play resigns from a match. This screen only happens when playing on local regular Smash, Special Smash, and 8-Player Smash, and does not happen when connecting on the internet. While on the screen, the character the player chose will appear on the screen clapping (some characters might not do this). So far, this screen happens in the victory screen area.
Super Smash Bros.
In the first Super Smash Bros. game of the series, the game cuts right in to the screen, while the background of the said screen fades in.
Super Smash Bros. Melee
The screen, like the previous one, just cuts in to the screen, but before the announcer yells "No Contest," the crowd groans in the background while the Smash Bros. emblem zooms out to the top left corner of the screen.
Super Smash Bros. Brawl
While the camera moves zooms out a little, the announcer yells "No Contest," before the crowd gasps in the background. The Smash Bros. emblem zoom outs in the near bottom left corner which then the "No Contest" sign appears after.
Super Smash Bros. 4
If the player decides to quit, the screen will fade to white then to the screen while the Smash Bros. emblem moves to the bottom right corner of the screen. The camera then zooms out a little more than the previous one, and the announcer yells "No Contest!"
