DOSDoom is the first source port of Doom, as well as the first DOS port of Doom after the release of the Doom source code. The initial versions were developed by Chi Hoang and the later ones by the DOSDoom Team. The port became the basis for a number of other source ports, including Boom, Doom Legacy and directly continued as EDGE. It pioneered many features that other source ports would come to adopt; due to this, EDGE is considered the purest descendant of the port. Because of this, its history, development, and team members are heavily documented here.
  • Chi Hoang released the initial version of DOSDoom on December 23, 1997, soon after the Doom source code came out. According to Hoang, "it took me 4-5 hours to port". Hoang left the port with 0.63.
  • The final version of DOSDoom, 0.653, was released on April 10, 1999.

Later DOSDoom versions added various new features including free look, translucency, jumping and DDF scripting.

The term "source port" originates from the DOSDoom release 0.2.

There is a campaign at Doomworld to retrieve the "lost" versions of DOSDoom, as only 3 versions (with 2 having their source released) exist.
