RUDE is a fork of Chocolate Doom 3.0.0 with some stuff from Crispy Doom. The name is some kind of play on words and stands for Romero's Ultimate Doom Engine and it's another tribute to John Romero. Easy to understand if you know my Romero's Heresy II project for Heretic. :)
It's a strong limit removing port aiming to fix game breaking bugs and prevent crashes while remaining faithful to the original executables. There are a few new gameplay features too. It's somewhere in the middle between Chocolate Doom and Crispy.
Please refer to the Chocolate Doom documentation. Also contains code from MBF and PrBoom+. Of course DOOM © 1996 id Software. Chocolate Doom © 2020 Simon Howard and Crispy Doom © 2020 Fabian Greffrath.

- Fixed backpacks from Marshmallow (idea and bits of code):
- Players now can exchange supplies (default backpack key is 'x', default stimpack key is 'c').

Chocolate Doom aims to accurately reproduce the original DOS version of Doom and other games based on the Doom engine in a form that can be run on modern computers.
Originally, Chocolate Doom was only a Doom source port. The project now includes ports of Heretic and Hexen, and Strife.
Chocolate Doom’s aims are:
- To always be 100% Free and Open Source software.
- Portability to as many different operating systems as possible.
- Accurate reproduction of the original DOS versions of the games, including bugs.
- Compatibility with the DOS demo, configuration and savegame files.
- To provide an accurate retro “feel” (display and input should behave the same).
More information about the philosophy and design behind Chocolate Doom can be found in the PHILOSOPHY file distributed with the source code.
For instructions on how to set up Chocolate Doom for play, see the INSTALL file.
Chocolate Doom is compatible with the DOS Doom configuration file
(normally named default.cfg). Existing configuration files for DOS
Doom should therefore simply work out of the box. However, Chocolate
Doom also provides some extra settings. These are stored in a
separate file named chocolate-doom.cfg.
The configuration can be edited using the chocolate-setup tool.
Chocolate Doom supports a number of command line parameters, including some extras that were not originally suported by the DOS versions. For binary distributions, see the CMDLINE file included with your download; more information is also available on the Chocolate Doom website.
With Vanilla Doom there is no way to include sprites in PWAD files. Chocolate Doom’s ‘-file’ command line option behaves exactly the same as Vanilla Doom, and trying to play TCs by adding the WAD files using ‘-file’ will not work.
Many Total Conversions (TCs) are distributed as a PWAD file which must be merged into the main IWAD. Typically a copy of DEUSF.EXE is included which performs this merge. Chocolate Doom includes a new option, ‘-merge’, which will simulate this merge. Essentially, the WAD directory is merged in memory, removing the need to modify the IWAD on disk.
To play TCs using Chocolate Doom, run like this:
chocolate-doom -merge thetc.wad
Here are some examples:
chocolate-doom -merge batman.wad -deh batman.deh vbatman.deh (Batman Doom)
chocolate-doom -merge aoddoom1.wad -deh aoddoom1.deh (Army of Darkness Doom)
-
Chocolate Doom includes a number of different options for music playback. See the README.Music file for more details.

More information, including information about how to play various classic TCs, is available on the Chocolate Doom website:

Chocolate Doom is not perfect. Although it aims to accurately emulate and reproduce the DOS executables, some behavior can be very difficult to reproduce. Because of the nature of the project, you may also encounter Vanilla Doom bugs; these are intentionally present; see the NOT-BUGS file for more information.
New bug reports can be submitted to the issue tracker on Github:
-
Source code patches are welcome, but please follow the style guidelines - see the file named HACKING included with the source distribution.
-
Chocolate Doom is distributed under the GNU GPL. See the COPYING file for more information.

Please send any feedback, questions or suggestions to chocolate-doom-dev-list@chocolate-doom.org. Thanks!
