International Doom is a small, functional and simple source port, created with help, efforts and bits of code from people around the world. Initially it was started in 2016 as translation-only project, but further development was inspired by Crispy Doom and Doom Retro source ports (and continued with extensive support from their authors - Fabian Greffrath and Brad Harding).

International Doom was previously known as "Russian Doom", but was renamed in response to the 2022 Russian invasion of Ukraine.^[1]

Major features[edit]

Optional True Color render.
Original, double and quad rendering resolution.
Uncapped framerate.
Additional, darker gamma-correction levels.
Support for OPL2, OPL3, MIDI, Fluidsynth and GUS music playback.

Various visual, audible, physical and demo enhancements.
Compatibility with vanilla-engine demos.
Removed limitations of vanilla engine.
Support for nodes in extended format (ZDBSP and DeePBSP).

Compatibility[edit]

Gameplay features from "Physical" and "Compatibility-breaking" sections are putting changes in game mechanics, making it no longer 100% original. However, these features are optional and never active in multiplayer and demo recording/playing to provide maximum compatibility and prevent desyncs.

Support for BOOM/MBF/MBF21 is not implemented.

Supported games[edit]

The following games are supported:

Doom shareware, registered, The Ultimate Doom
Doom II
- No Rest for the Living
Final Doom
SIGIL
Freedoom (Phase 1 and 2, FreeDM)
