Doom64EX is a reverse-engineering project aimed to recreate Doom64 as close as possible with additional modding features.

NOTICE 2nd February 2017 The supplementary data file kex.wad has been renamed to doom64ex.pk3.

At the moment there are no official binary builds. You can find older versions here.

It's possible to compile Doom64EX yourself. Officially, only Linux, Windows and macOS are supported. Patches for alternative operating system are gladly accepted, however.

* MSYS2 uses a naming convention similar to the one utilised by Arch, except packages are prefixed with mingw-w64-i686- and mingw-w64-x86_64- for 32-bit and 64-bit packages, respectively.

** FluidSynth is optional. The fluidsynth-lite fork can be used instead.

Note: You may also need to install dynamic libraries separately.

Doom64EX uses fluidsynth-lite to reduce the number of dependencies. If you wish to use FluidSynth as provided by your package-manager, add -DENABLE_SYSTEM_FLUIDSYNTH=ON as a cmake argument.

$ cmake -DENABLE_SYSTEM_FLUIDSYNTH=ON ..

All of these steps are done using the terminal.

On Ubuntu:

$ # Add additional toolchains
$ sudo add-apt-repository ppa:ubuntu-toolchain-r/test
$ sudo apt update

$ # Install GCC
$ sudo apt install build-essential gcc-6 g  -6

$ # Install dependencies
$ sudo apt install git cmake libsdl2-dev libsdl2-net-dev zlib1g-dev libpng-dev

On Fedora:

$ # Install development group
$ sudo dnf groupinstall "Development Tools and Libraries"

$ # Install dependencies
$ sudo dnf install git cmake sdl2-devel sdl2_net-devel zlib-devel libpng-devel

On Arch Linux:

$ # Install dependencies
$ sudo pacman -S git gcc cmake sdl2 sdl2_net zlib libpng

Find a suitable place to build the program and navigate there using cd.

$ # Clone this repository (if you haven't done so already)
$ git clone https://github.com/svkaiser/Doom64EX --recursive
$ cd Doom64EX

$ # If you have previously cloned the repository, you'll need to also grab the fluidsynth-lite submodule
$ git submodule update --init --recursive

$ mkdir build       # Create a build directory within the git repo
$ cd build          # Change into the new directory
$ cmake ..          # Generate Makefiles
$ make              # Build everything
$ sudo make install # Install Doom64EX to /usr/local

You can now launch Doom64EX from the menu or using doom64ex from terminal.

NOTICE Ubuntu ships with a severely outdated version of CMake, so you'll need to create the doom64ex.pk3 file manually.

Download and install CMAKE. Follow the instructions on the website and make sure to update the system. Clone the repository in a suitable place to build the program.

Next, download the Win32 Dependencies. Extract the archive into the extern directory. Also remember to clone fluidsynth-lite and generate the .lib and .dll files. Place these in extern\lib and extern\bin, respectively.

Next, generate the MSVC project files.

$ mkdir build                           # Create a build directory within the git repo
$ cd build                              # Change into the new directory
$ cmake .. -G "Visual Studio 15 2017"   # Generate MSVC 2017 files

Visual Studio 2017 project files will now be sitting in the build directory.

Install Xcode for its developer tools. Follow the instructions to install Homebrew. You can probably use other package managers, but Doom64EX has only been tested with Homebrew.

Open Terminal.app (or a terminal replacement).

$ # Install dependencies
$ brew install git cmake sdl2 sdl2_net libpng zlib

Find a suitable place to build the program and navigate there using terminal.

$ # Clone this repository (if you haven't done so already)
$ git clone https://github.com/svkaiser/Doom64EX --recursive

$ # If you have previously cloned the repository, you'll need to also grab the fluidsynth-lite submodule
$ git submodule update --init --recursive

$ mkdir build       # Create a build directory within the git repo
$ cd build          # Change into the new directory
$ cmake ..          # Generate Makefiles
$ make              # Build everything
$ sudo make install # Install Doom64EX.app

You will now find Doom64EX in your Applications directory.

If for some reason CMake refuses to automatically generate the required doom64ex.pk3, you can easily create it yourself.

The data files required by Doom64EX to function are:

• doom64ex.pk3 (Generated by cmake)
• doom64.wad
• doomsnd.sf2

To generate the two latter files, acquire a Doom64 ROM and run:

$ doom64ex -wadgen PATH_TO_ROM

This will generate the required files and place them somewhere where Doom64EX can find them.

Doom64EX needs the Doom 64 data to be present in any of the following directories.

• Current directory
• The directory in which the doom64ex executable resides
• $XDG_DATA_HOME/doom64ex (usually ~/.local/share/doom64ex)
• /usr/local/share/games/doom64ex
• /usr/local/share/doom64ex
• /usr/local/share/doom
• /usr/share/games/doom64ex
• /usr/share/doom64ex
• /usr/share/doom
• /opt/doom64ex

• Current directory
• The directory in which the doom64ex executable resides

• Current directory
• ~/Library/Application Support/doom64ex
