The present article is a list of known platforms to which Doom has been confirmed to be ported.
Doom is one of the most widely ported video games. Since the original MS-DOS version, it has been released officially for a number of operating systems, video game consoles, handheld game consoles, and other devices. Some of the ports are replications of the DOS version, while others differ considerably, including modifications to the level designs, monsters and game engine, with some ports offering content not included in the original DOS version.
Official ports
Personal computers
NeXTSTEP
This was the version that the MS-DOS product emerged from, since, at the time, id Software was using a NeXTcube for its graphic-engine development. This version is sluggish on anything below an 040 NeXTstation/cube (though it runs smoother with a higher amount of memory), and is missing sound, which was added on the PC side. With NeXT-Step based on i486 architecture, it ran smoothly under all conditions up to screen sizes of 400% with newer hardware. The version running on NeXT is programmed by John Carmack, John Romero, and Dave Taylor.
OS/2
Doom was ported to OS/2 by an independent contractor, Jim Thomas, who was hired by IBM to port it and SimCity. A successful version was demoed in 1994 running in an OS/2 PM window.
IRIX
Doom was ported to IRIX during the summer of 1994 by Dave D. Taylor. IRIX Doom was originally based on the unreleased MS-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 rendering mode.
Solaris
Doom was ported to Solaris in late 1994, and was designed to run with game files from Doom 1.8. In the readme, the port is credited to "Dave Taylor and the rest of the folks at id Software". It runs on Solaris 2.4 and later. The distribution contained two versions: one for regular X11, and another for Sun DGA.
macOS
Doom for Mac was released on November 4, 1994. The Ultimate Doom, Doom II, and Final Doom were ported by Lion Entertainment and released by GT Interactive using a Mac OS launcher application to run original PC WADs. The Mac version runs on System 7 through Mac OS 9 and requires a 68040 or PowerPC processor. Although it can run in Classic under Mac OS X on Power Macs, Panther and Tiger cause graphic artifacts due to the later version of Classic having a double-buffered screen. It can also be played under emulation on Intel and Apple silicon Macs with SheepShaver and QEMU. In addition to an adjustable viewport, it supports rendering at low or high resolutions, and allows network play over AppleTalk as well as IPX.
Linux
Doom was ported to Linux by id Software programmer Dave Taylor in 1994. The last Linux Doom binaries were provided by id Software on October 13, 1996, through the company's ftp-server.
The source code to the Linux version of Doom was released by id Software on December 23, 1997, under a non-profit End user license agreement; it was re-released on October 3, 1999, under the terms of the GPL-2.0-or-later license. However, the source codes to the DOS and Windows versions of the game were not released, due to copyright issues concerning the sound library used by original DOS version and id Software having no access to the source code of the Windows port.
Microsoft Windows
The first version of Doom for Windows was released under the name Doom 95, on August 20, 1996. It was compatible with Windows 95 and up, and was able to use WADs from the DOS versions. It also allowed users to set up multiplayer games much easier than in DOS. It was included with Final Doom. The port was project-led by Gabe Newell and other later founders of Valve.
On September 26, 2001, Doom Collector's Edition was released, containing The Ultimate Doom, Doom II, and Final Doom. It was re-released on January 1, 2004 with added preview content for Doom 3. Some early versions of Doom 3 included the Collector's Edition and a small demon figurine as a bonus. The BFG Edition of Doom 3, released on October 15, 2012, includes The Ultimate Doom as well as Doom II.
On August 3, 2007, The Ultimate Doom, Doom II, and Final Doom were released on Steam. This release runs the original DOS versions of the game using DOSBox, a DOS emulator.
