Eternal Doom MAP01 TAS in Eternity Engine

Tool-assisted speedrun of Eternal Doom MAP01 in 3:31 by Andy Olivera, recorded in TASDooM and played back in the Eternity Engine v3.35.92. Eternity is an advanced DOOM source port that is uniquely also highly compatible with the original executable, and can play nearly all demos recorded with it, as well as popular variants such as Doom Plus and PrBoom 2.02. I have been working on the Eternity Engine since 1998. See http://doomworld.com/eternity/ for more information. Note that the sound in this video clips pretty badly; I am trying to figure out the problem before I upload any more videos.
