Doomed Speed Demos Archive
The DooMed Speed Demos Archive (often abbreviated DSDA) is a website that collects speedruns for various PWADS. It was created by Opulent on September 1st, 2000, and has been run by Andy Olivera since November 12th, 2008.
As of August 2019, the archive contains well over 53,000 demos by more than 670 speedrunners. It allows many different demo types, expanding on those allowed in Compet-n. It also offers tutorials on recording and playing demos, hosts binaries of various source ports and useful utilities.
The DSDA lists all players and their contributions to the archive, including total running time and ratings.
In 2019 a new version of the DSDA was launched by Kraflab and Zero-Master, completely rewritten in a modern layout to allow updates by a team of maintainers, support non-Doom games, show detailed demo information such as times in tics, and more. It currently mirrors demos from Olivera's site weekly while more features are being developed, including an API.
