Disable vertical mouse movement[edit]

Game forces vertical mouse movement (forward and backward movement via mouse).
Automating novert in DOSBox (Steam release)[3]
novert is a program that disables vertical mouse input.
  1. Download novert and extract novert.com in <path-to-game> alongside DOOM2.EXE.
  2. Edit ultimate.conf and ultimatem.conf with a text editor, and in the [Autoexec] section, add novert.com before the line calling the game's executable.
  3. Save the changes in the *.conf files and close.

Source ports[edit]

A more exhaustive list is available on Wikipedia and a set of comparison tables is available on DoomWiki.org.
Latest Git builds of ZDoom, GZDoom, QZDoom, and Odamex are available at DRD Team Development Builds.
Name Description
ZDoom Renderers available: Software.
Limit-removing source port that has features such as high resolutions and all-new editing features for modders.
No longer maintained by the original developer.[4]
macOS (OS X)
GZDoom Renderers available: Software, OpenGL.
Based on the same code as ZDoom, except it also uses an OpenGL renderer. Nearly every mod should work with GZDoom, specifically ones that use special effects.
macOS (OS X)
QZDoom Renderers available: Direct3D, OpenGL.
An experimental branch of GZDoom to test new stable features.
macOS (OS X)
Zandronum Renderers available: Software, OpenGL.
Based off modified ZDoom code. Use this source port to play online, as it significantly overhauls the netcode from ZDoom.
macOS (OS X)
Odamex Renderers available: Software.
Source port based on ZDoom 1.22 (and parts of 1.23) that focuses on multiplayer while staying close to the original Doom.
macOS (OS X)
PrBoom Renderers available: Software, OpenGL.
Limit-removing source port based off Boom that aims to preserve the feel of vanilla Doom while adding modern editing features. Includes an OpenGL renderer and supports high resolutions.
macOS (OS X)
PrBoom+ Renderers available: Software, OpenGL.
Based off PrBoom. Extends the port with more features.
macOS (OS X)
Chocolate Doom Renderers available: Software.
Source port that aims to accurately reproduce the experience of playing vanilla Doom. Renders at a low-resolution (that's upscaled to higher resolutions) and purposefully keeps the original game's limits.
macOS (OS X)
Doom Retro Renderers available: Software (with acceleration), Direct3D, OpenGL.
Source port based off Chocolate Doom that supports vanilla, limit-removing and Boom-compatible maps and makes a few other changes/fixes for the modern age while still keeping the classic Doom experience.


Useful for source ports, launchers enable the user to manage mod files and their load order, add launch arguments and save all this in a profile for future use.

Name System Notes
SSG Launcher Windows, Mac OS X, Linux The launcher also has the extra functionality with launching Doom 64 EX, the DoomRPG mod, and also the OBLIGE Level Maker.
ZDL Windows A simple, but powerful launcher.
RocketLauncher Windows, Linux Based on Qt, RocketLauncher consists many features to customize your game and a support for DOSBox. Linux users should compile it in order to install it.
Doom Launcher Windows Features automatic mod download from /idgames database.

Enhancement mods[edit]

DOS and all source ports[edit]

  • Minor Sprite Fixing Project - Corrects sprite offsets and other graphical errors. Compatible with both original DOS release and source ports.

ZDoom-based source ports[edit]

  • Master Levels Menu Interface - An in-game menu that serves to replace the old DOS program that would launch a chosen WAD of the Master Level for Doom II expansion. This mod allows you to play them in one sitting without restarting the game or loading each individual WAD file.
  • WadSmoosh - Combines all the official classic Doom IWADs (Doom, Doom II: Hell on Earth, Master Levels for Doom II, and Final Doom) the user can provide, as well as the No Rest for the Living WAD from Doom 3: BFG Edition, into a single PK3 IWAD with each game selectable as episodes. The bonus secret levels from the Xbox port of Doom 3 can also be integrated.

Any source port[edit]

  • Widescreen Status Bar - Designed for compatible source ports that support widescreen resolutions. In addition to removing the brick patterns that appear on the side of the bar when upscaling it, it also helps prevent graphical glitches that sometimes occurs from the upscaling process. Some source ports may require adjusting the status bar upscaling size manually in their respective options menu to retain the intended aspect-ratio.
