Sgidoom

sgidoom was a demo of Doom on IRIX included with many IRIX demo CDs in the 1990s.

Specifications

It was designed to run on IRIX 5.3 and later. IRIX Doom was originally based on the unreleased DOS version 1.5, though later updates were based on versions 1.6 and 1.8. No effort was made to take advantage of SGI's advanced graphics hardware, and like many other ports the game was rendered entirely in software.

sgidoom lacks sound, but includes sndserver for network play.

It is known for having some memory leaks and other issues. Nekoware includes a newer version of Doom in the form of Chocolate Doom.
