Chocolate Quake

Chocolate Quake is a minimalist source port of Quake focused on preserving the original experience of version 1.09 and earlier DOS releases. Inspired by the philosophy of Chocolate Doom, this project aims for accuracy and authenticity over modern enhancements.

Chocolate Quake's aims are:

• Reproduces the behavior of Quake v1.09 (WinQuake) and earlier DOS versions with high accuracy, including original bugs and quirks.
• Input handling, rendering, and timing are designed to closely match the original experience.
• No hardware acceleration or modern visual effects.

Philosophy

This port is for purists: no fancy enhancements, no modern effects, just Quake as it was. If you're looking for visual upgrades or modern features, this may not be the port for you. But if you want Quake exactly as it felt in the '90s, you're in the right place.

Build Instructions

Chocolate Quake uses CMake (>= 3.21) and is built as a C99 project. Predefined CMake presets are provided to simplify building across platforms.

The repository includes vcpkg as a Git submodule, which is the recommended way to build Chocolate Quake on Windows and macOS.

Requirements

• C compiler with C99 support
• CMake 3.21 or newer
• Ninja (recommended)
• Git
• SDL2 >= 2.26.5
• SDL2_net
• Audio libraries:
  • libvorbis + libvorbisfile
  • libflac
  • libmad (MP3)

Cloning the repository

If you are not using vcpkg:

git clone https://github.com/Henrique194/chocolate-quake.git

If you plan to use vcpkg to manage dependencies:

git clone --recurse-submodules https://github.com/Henrique194/chocolate-quake.git

If you already cloned the repository without submodules and want to fetch vcpkg later:

git submodule update --init --recursive

Windows and macOS (using bundled vcpkg)

The project provides CMake presets to build with vcpkg. From the repository root:

cmake --preset release-vcpkg

cmake --build --preset release-vcpkg

For a debug build:

cmake --preset debug-vcpkg

cmake --build --preset debug-vcpkg

Linux

On Linux, Chocolate Quake is typically built against system-provided libraries.

Install the required dependencies using your distribution's package manager, then build using the provided presets:

cmake --preset release

cmake --build --preset release

For a debug build:

cmake --preset debug

cmake --build --preset debug

Build output

Once compilation is complete, the resulting executable can be found at:

• Release build: cmake-build-release/src/Release
• Debug build: cmake-build-debug/src/Debug

Running The Game

To run Chocolate Quake, you need a directory named id1 containing your game data (PAK files). You can also customize the location and name of the game directory using the command-line parameters (-basedir and -game, respectively). Most IDEs also allow you to set a working directory so the game directory can be placed in a more convenient location, without the need for command-line parameters.

By default, Chocolate Quake searches for the id1 directory in the following location:

• Windows: The same directory as the executable.
• macOS: /Users/<your-user>/Library/Application Support/chocolate-quake
• Linux: /home/<your-user>/.local/share/chocolate-quake

Music

Chocolate Quake supports external music playback in MP3, OGG, FLAC and WAV formats. To enable it:

• Create a directory named music inside your id1 game folder.
• Place your music tracks in this directory.

Tracks should follow the naming convention track02.ogg through track11.ogg, matching the original CD audio.
