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. Official ports Personal computers NeXTSTEP 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. 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 ĭoom 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 ĭoom was ported to IRIX during the summer of 1994 by Dave D. 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.ĭoom 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'.

The distribution contained two versions: one for regular X11, and another for Sun DGA. macOS ĭoom 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.
