Master of Magic - Reassembled

ReMoM

Remaking the game 'Master of Magic' from 1994-95, all from disassembling the original executables and reassembling and translating it to C.

The goal of this project is to recreate a functional source code for Master of Magic, to allow the community to improve and expand the Simtex Universe to their hearts content.

To get involved, or even just hang out with other MoM fans, join us on the the "Master of Magic - Fans" Discord Server. This particular project is hosted by the #mom-reverse-engineering Channel, on that server.

Download and Play

Pre-built, engine-only binaries are available on the Releases page. You supply your own original game data files.

1. Download the artifact for your platform:
   • Windows: the .zip, or run the .exe installer. Self-contained — the SDL runtime DLLs are bundled.
   • Linux: the .deb on Debian/Ubuntu (sudo apt install ./remom_<ver>_amd64.deb — installs it properly, apt pulls in SDL2); the .AppImage on any other distro (self-contained); or the .zip/.tar.gz if you already have SDL2 installed.
   • macOS: the .zip. It's unsigned, so on first run clear the quarantine flag: xattr -dr com.apple.quarantine ReMoM.
2. Extract it (on Linux/macOS, chmod +x the AppImage / ReMoM).
3. Copy your original Master of Magic v1.31 game files (all .LBX files and CONFIG.MOM) into the same folder as the executable.
4. Run ReMoM.

How to Build

Prerequisites

• CMake 3.25+ (for preset support)
• A rendering/audio backend, depending on platform/preset:
  • Windows (MSVC-* presets): SDL2 + SDL2_mixer (default) — CMake looks under C:\devellib\ (e.g. SDL2-2.32.2, SDL2_mixer-2.8.1). The native Win32 backend (no SDL) is opt-in via the MSVC-win32-* presets.
  • Linux / macOS: SDL2 + SDL2_mixer development files. SDL2 is the default backend; SDL3 is opt-in via -DUSE_SDL3=ON (use a no-sound preset to build without the mixer).
• A C/C++ toolchain:
  • Windows: Visual Studio 2022 (x64 C++ tools)
  • Linux: GCC or Clang, plus Ninja or Make

Build presets are defined in CMakePresets.json.

---

Windows (MSVC)

cmake --workflow --preset=MSVC-debug

This runs configure, build, test, and package steps in one command. The MSVC-* presets use the SDL2 backend (needs SDL2 + SDL2_mixer under C:\devellib\; see below).

Explicitly without audio:

cmake --workflow --preset=MSVC-nosound-debug

Or run steps individually:

cmake --preset MSVC-debug
cmake --build --preset MSVC-debug
ctest --preset MSVC-debug

The MSVC-* presets need SDL under C:\devellib\ (e.g. SDL2-2.32.2 + SDL2_mixer-2.8.1, or SDL3-3.4.2 with -DUSE_SDL3=ON); pass -DCMAKE_PREFIX_PATH=C:\your\path to use a different location. For the self-contained silent native-Win32 build (no SDL), use the MSVC-win32-* presets instead. See BUILDING.md.

---

Linux (Kubuntu 24.04 / Ubuntu / Debian)

1. Install build tools

sudo apt install build-essential cmake ninja-build curl pkg-config clang

If your distro's CMake is too old (need 3.25+), install the latest from Kitware:

curl -fsSL https://raw.githubusercontent.com/jbalcomb/ReMoM/main/scripts/install-cmake-linux.sh | bash

2. Install SDL2

SDL2 is the default backend and is in the distro repos:

sudo apt install libsdl2-dev libsdl2-mixer-dev

(SDL3 is optional — opt in with -DUSE_SDL3=ON; see BUILDING.md. To build without audio, use the clang-nosound-debug preset.)

3. Build ReMoM

cmake --workflow --preset=clang-debug

Or run steps individually:

cmake --preset clang-debug
cmake --build --preset clang-debug
ctest --preset clang-debug

---

Notes

• All available presets are listed in CMakePresets.json.
• GoogleTest v1.17.0 is fetched automatically via CMake's FetchContent — no manual install needed.
• Game assets (LBX files, CONFIG.MOM) are expected in the assets/ directory and are copied to the build output automatically.
