TASDoom was a source port and fork based on DOSDoom version 0.47, made specifically for TAS demos. It is based off a program by Andy Kempling (aurikan), called lmpcheat, which along with another program of Kempling's called Timer became the basis for TASDoom.


TASDoom was created out of a need for more granularity in recording demos. Till then, demos were recorded in DOOM2.EXE and DOSDoom which didn't support advanced TAS features. It was derived from lmpcheat which allowed recording in slow-motion and in multiple sessions. These formed the basis for TASDoom. As a result, a TASDoom demo cannot run in DOSDoom, although converters exist.

TASDoom saw a single release, which was on December 15, 1998. It became a popular choice to record LMPs with alongside its bigger brother, TASMBF. As the years progressed, TASDoom was slowly replaced by new ports that could run under multiple operating systems, such as PrBoom.
