is a mod of Super Smash Bros.
It is the first notable mod for the game, with development having started in May of 2015. 19XXTE
is based on 20xx tournament edition; that is, the purpose of the mod is to assist in running tournaments, help players learn the game, and add other cosmetic changes instead of exclusively modifying characters or stages. 19XXTE
has seen tournament use. Its most important feature is the ability to add a timer to a stock match like in later games, saving tournament organizers from keeping track of match time externally.
