novert

When using the keyboard and mouse configuration in Doom or similar games on DOS or through DOSBox, vertical mouse movement causes the player to move forward and back, which can make mouse aiming difficult. novert is a DOS TSR that disables vertical mouse movement to prevent unnecessary player movement.

Source ports

Since the release of the source code, several modified engines have emerged.

Name	Notes	Renderer
ZDoom	Limit-removing source port that has features such as high resolutions and all-new editing features for modders. Most mods are designed around ZDoom's features. Uses a software renderer which could cause some incompatibility issues with mods that use special effects reliant on OpenGL like Brutal Doom. No longer in development by the original developer.	Software
GZDoom	Based on the same code as ZDoom, except it uses an OpenGL renderer. Nearly every mod should work with GZDoom, specifically ones that use special effects.	OpenGL
QZDoom	A successor to ZDoom, based off GZDoom except it uses a 32-bit true-color renderer instead of an 8-bit one.	Direct3D, OpenGL
Zandronum	Based off modified ZDoom code. Use this source port if you want to play multiplayer, as it significantly overhauls the netcode from ZDoom. Basic mods that change the maps are fully supported, but more complex mods such as Brutal Doom varies. Check to see if the mod supports Zandronum or if there's a separate version that does.	Software, OpenGL
Odamex	Source port based on ZDoom 1.22 (and parts of 1.23) that focuses on multiplayer while staying close to the original Doom. Not as widely used as Zandronum.	Unknown
PrBoom	Source port based off Boom (a source port that was made by TeamTNT) that uses an OpenGL renderer that supports high resolutions.	OpenGL
PrBoom+	Based off PrBoom that attempts to extend the port with more features.	Software, OpenGL
Chocolate Doom	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.	Software
Doom Retro	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.	Software with hardware acceleration, Direct3D, OpenGL

You can view a more exhaustive list on Wikipedia or a set of comparison tables on DoomWiki.org. The history of various source ports is examined on Doomworld.

Super Shotgun Launcher

If using a source port, you can use this launcher to load up custom WADs/PK3s in the ZDoom, GZDoom, and Zandronum source ports without needing to drag and drop or using command-lines. The launcher also has the extra functionality with launching Doom 64 EX, the DoomRPG mod, and also the OBLIGE Level Maker. The launcher can be downloaded here.

Master Levels Menu Interface

If using the ZDoom source port or its derivatives, The Master Levels Menu Interface is 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 ZDoom or similar source ports and loading each individual WAD file.

WadSmoosh

If using the ZDoom source port or its derivatives, you can use JP LeBreton's WadSmoosh tool to combine any of the official DOS-era Doom games' IWADs (Doom, Doom II: Hell on Earth, Master Levels for Doom II, and Final Doom) that you own, as well as the No Rest for the Living IWAD from Doom 3: BFG Edition, into a single PK3 IWAD with each game selectable as episodes. The tool along with a guide to use it can be found here.

Content

A freely redistributable replacement of DOOM-like assets is available at Freedoom, forming a completely free and open source game. Art assets from the original game such as the levels, sounds, textures, etc., remain under copyright. They can be purchased from Steam, GOG.com, or copied from an original game disc.

Depending on your choice of engine, you can usually change the field of view with a console command, or even in the options. Try fov <1-179> or gr_fov <1-179>.

Multi-monitor

ZDoom seeks to support multiple monitors out of the box since version 2.5.0. Widescreen Gaming Forum discusses multi-monitor set ups with GZDoom.
