|*Measured using Budko's PrBoom modification.|

The demo was recorded on a modified version of PrBoom written by Budko himself. This version was the base for PrBoom+. The main feature of his custom version not present in the original PrBoom is the ability to activate permanent strafe50. All versions of PrBoom include slow-motion recording and save states, the latter of which Budko used sparingly. 
Budko's run eclipsed the March 2000 tool-assisted record of 16 minutes, 17 seconds by Marijo "Sedlo" Sedlic in 30uv1617. This was achieved by taking advantage of newly-discovered routes and tricks, and the use of the strafe50 modification.
Since releasing 30uv1441, Budko has also set world records for tool-assisted runs in three out of the four episodes in Ultimate Doom: Knee-Deep in the Dead in 04:05; Inferno in 03:15; and Thy Flesh Consumed in 02:32.
30uv1441 is not a maxed-out speedrun. On the Doomworld forums in January 2004, Budko announced the possibility of recording an updated Doom II speedrun with a running time under 14 minutes, but never did it.
A built run in 14:02, by Adrian Danis (RamboBones), exists.
