Yet another purist DOOM port.

This project aims to repair the Linux Doom source code, restoring features that were lost from the DOS version, and implementing opt-in quality-of-life improvements such as widescreen rendering.

Features

Repaired Downgrades

• Features that were broken by the original Linux port:
  • Music support (through WildMIDI).
  • Complete sound effect support (restored missing features such as stopping mid-playback and updating positional effects).
  • Low-detail mode.
• Features that were broken by the 1997 source release:
  • Animated Doom 1 intermission screens.
  • Ultimate Doom wall switch textures.
  • Volume levels and volume control.

Portability Improvements

• Addressed various compiler warnings.
• Support for 64-bit CPUs.
• Support for Windows and modern Linux:
  • The X11 code has been converted from 8bpp to 24bpp, which is supported by modern X11 servers.
  • The audio code has been migrated from OSS to the miniaudio middleware library (supports OSS, ALSA, PulseAudio, JACK, and more).
  • As an alternative to X11 and miniaudio, SDL1 and SDL2 backends are available.
  • The codebase can be compiled with MSVC.
  • Windows networking code has been added.
• Eliminated reliance on C99 and C extensions, making the codebase pure ANSI C.

Quality-of-Life Improvements

• New configuration options:
  • novert - Disables being able to make the player character walk by moving the mouse up and down.
  • always_run - Makes the player character run instead of walk, and vice versa.
  • aspect_ratio_correction - Restores the original 4:3 aspect ratio by making pixels rectangular.
  • full_colour - Render with more than 256 colours.
  • prototype_light_amplification_visor_effect - Restore the 'night vision' effect for the light amplification visor from the Press Release Pre-Beta.
  • screen_width - The screen's horizontal resolution. The maximum is 5040.
  • screen_height - The screen's vertical resolution. The maximum is 1800.
  • hud_scale - Multiplies the size of the user interface. 1 renders elements at their native resolutions, 2 renders them at double their resolution, etc. The maximum value is 9.
• The 'iddt' cheat enables kill/item/secret totals in the automap, as well as notifications when finding secrets.
• Assorted bug fixes.
• Better than CuckyDOOM.

Configuration

Additional settings are found in the configuration file - 'clowndoomrc'. On Unix platforms, it can be found in the user's standard configuration directory (XDG_CONFIG_HOME, or ~/.config/ if it is undefined) named 'clowndoomrc'. On other platforms, it can be found in the same directory as the executable (or whichever directory the executable was invoked from) with the name 'default.cfg'.

WildMIDI requires a collection of GUS patches in order to work. The patches should come with a Timidity-compatible '.cfg'. file. Set the wildmidi_config_path option in 'clowndoomrc' to the path of this file, and music should now work.
