Speed Demos Archive (abbreviated SDA) is a site dedicated to speedruns done on many computer and video games.
History
The site originally began as a demo archive of Quake play throughs. SDA was formed initially by Nolan "Radix" Pflug by merging with a site created by Gunnar and Jesse in April of 1998. In 2004 after the success of his own famous 100% Metroid Prime run, Radix expanded SDA to include demos of other games.
As of March 2nd, 2004, SDA is now home to numerous videos of gamers completing various video games as quickly as they can. Players may do the runs in a single segment (single sitting) or in multiple segments using the game's built-in saving system. Runs saved in multiple segments are usually downloaded part by part, which is helpful when one does not have time to watch or download an entire run. Almost every speedrun on SDA can be downloaded in low, normal, or high quality to suit differing bandwidths. In some cases there is also an "insane" video quality available. Runs must be performed on their native consoles or on certain PC/Mac configurations. Runs done on emulators are not accepted, since it cannot be proven that a user did not use any tools to assist them. Runs of an alternate mode within the game (such as Devil May Cry's Super Dante mode) can be accepted, but for the first runs of a game to be uploaded, it is preferred they be "out-of-the-box" runs (playing the game the first time).
