Chi Hoang is most well-known for making the first DOS port of Doom after the release of the Doom source code. As the released source code was the source to the Linux port, it was at first not possible to compile it for DOS. Hoang's port, known as DOSDoom, became the basis for a number of other source ports, including Boom, Doom Legacy and EDGE. The port was later developed by the DOSDoom Team, and then absorbed into EDGE.
