Magic Carpet 2 HD

Now actually in HD or 2K!

Based off the Reverse engineering of game Magic Carpet 2 from assembler to c/c++ language by Tomas Versly
Forked from Tomas Vesely's repo here: https://github.com/turican0/remc2

Tomas has done amazing work, not only reverse engineering this code but updating it to use more modern memory allocation and use the SDL library for input and sound. He has even increased the sprite resolutions.

For more information on Magic Carpet 2

Moburma has been tirelessly working to document cut levels, level data structures and missing graphics at: https://tcrf.net/Magic_Carpet_2:_The_Netherworlds

My intention is to make a patch for Magic Carpet 1 and 2 (GOG editions) that initially will:

  • Add more screen resolution options
  • Increase draw distance
  • Seperate Render and Simulation code so that game speed is not dependent of FPS (or fix FPS)
  • Enable local multiplayer without NETBIOS

Build Status:

Branch Windows Linux
master MSBuild CI Linux 64bit CI
development MSBuild CI Linux 64bit CI

STATUS: Code now runs and all of MC2 (in both Windows and Linux) seems to be playable. Anyone with the GOG edition can download this repo, extract the Game Assets (from a legal GOG copy of the game) and run it.

Steps: to build and run this code

Windows:

  • 1: Install the latest version of Visual Studio 2022 Community. Ensure you install vcpkg
  • 2: Pull the development branch
  • 3: Open "remc2.sln", you can build either x64 or 32 bit versions
  • 4: Build the code
  • 5: Purchase a copy of Magic Carpet 2 from GOG here: https://www.gog.com/game/magic_carpet_2_the_netherworlds
  • 6: Install the Game. Copy the "NETHERW" directory to "remc2\Debug" Folder
  • 7: Copy the "Extract" folder to your Game Directory, run extract-GOG-CD.bat. The CD Data will now be copied to a directory called "CD_Files" in the "Extract" directory
  • 8: Move "CD_Files" directory into the "remc2\Debug" Folder
  • 9: Run

Linux:

Building on Linux

There are two ways to build the Linux binary.

  • Building a native binary

    1. Pull the development branch using GitHub (this is much easier if you install Visual Studio Code and install C++ Extension, cmake, cmake tools). When pulling the branch either do a recursive clone of the repository or ensure that after the pull you run: git submodule init and git submodule update
    2. Make sure that you have CMake, make and a recent GCC installed
      • To install them on Debian/Pi OS: sudo apt install -y cmake
    3. Make sure that you have the following dependencies as development packages (the exact names depend on your distro)
    • SDL2
    • SDL2_mixer
    • SDL2_image
    • SDL2_ttf
    • libpng
    • boost
    • boost-system
      • To install them on Debian/Pi OS: sudo apt install libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev libpng-dev libpng++-dev libboost-system-dev
    1. Build the code
    export BUILDTYPE=Debug # or Release
mkdir -p build/${BUILDTYPE}
cd build/${BUILDTYPE}
cmake -DCMAKE_BUILD_TYPE=${BUILDTYPE} -DCMAKE_INSTALL_PREFIX=./inst [SOURCE_DIR]
make
make install
    1. Magic Carpet 2 is now built. you can find it in build/Debug/inst/bin
      • You can also run the code with sanitizers (leak, address, undefined behaviour, pointers) by passing -DUSE_SANITIZERS=True to CMake
      • Additionally you can compile the code with clang-tidy analyzers by passing -DUSE_CLANG_TIDY=True to CMake

  • Building a flatpak

    1. Pull the development branch
    2. Build the flatpak
    cd flatpak
./build.sh
    1. Run the remc2 flatpak via
    flatpak run com.github.thobbsinteractive.magic-carpet-2-hd

Providing the original game assets to remc2 and running the game

In order to run the game you need to own a copy of Magic Carpet 2. We provide a script to extract the assets from the GOG version. The following steps extract the required files from the original.

  1. Purchase a copy of Magic Carpet 2 from GOG here: https://www.gog.com/game/magic_carpet_2_the_netherworlds
  2. Download the Windows "Offline Backup Game Installer"
  • Open GOGGalaxy
  • Install the game
  1. In order to retrieve the original game's assets run the following script located in the root of the repository:
bash check_install.sh -s [directory where GOG installed MC2] -d [destination directory]
# for example :
bash check_install.sh -s "${HOME}/.wine/drive_c/games/Magic Carpet 2/" -d "build/${BUILDTYPE}/inst/bin/"

Please note that if you have used any other method to get the assets, at least run a check to make sure that remc2 has access to every file it needs:

bash check_install.sh -d [destination directory]
# for example:
bash check_install.sh -d "build/${BUILDTYPE}/inst/bin/"
 [ ok ] CD_Files directory
 [ ok ] GAME directory

this script will fix the permissions, make everything uppercase, check all file hashes and complain if any file is missing. it's also recommended that before the first run you remove the file GAME/NETHERW/CONFIG.DAT if it exists. 4. NOTE: The game will search in the following locations (and in this particular order) for the game assets. For the flatpak only the first two locations can be used. 1. $XDG_DATA_HOME/remc2/ 2. $HOME/.local/share/remc2 3. next to the remc2 binary 5. Run the remc2 executable in install directory

cd magic-carpet-2-hd/build/${BUILDTYPE}/inst/bin
./remc2

Configuring remc2

Some settings can be configured via the file config.ini. An example for this file can be found in the root directory of the remc2 repository. The game will search for this file in the following locations and this particular order. For the flatpak only the first two locations can be used.

  1. $XDG_CONFIG_HOME/remc2
  2. $HOME/.config/remc2
  3. next to the remc2 binary

ROADMAP:

MILLSTONE 1

  • Get solution runnable from Visual Studio 2019 build, with minimum of setup. Cut down on unnecessary extra files and libraries and use nuget instead.
  • Refactor reverse engineered code into seperate classes where possible.

MILLSTONE 2

  • Add resolution support
  • Implement Open GL render
  • Implement Controller Support
  • Implement a (platform independent) Launch menu to adjust settings in config.ini before launch

MILLSTONE 3

  • Improve sounds and music using updated original scores and directional sounds in game - In Review!
  • Implement a wix sharp .msi installation for new .exe to make patching the and running existing game simple and something similar for the Linux versions

MILLSTONE 4

  • Get basic LAN/IPv4 multiplayer working again (Tom is currently making great progress on this!)

MILLSTONE 5

  • Get Magic Carpet 1 working using this engine. Ideally with original music and graphics.

LONG TERM GOALS

  • Add VR support back into the game (yes it was originally supported! This game was waaay ahead of its time)
  • Implement online multiplayer match making

Development Guide

  • The Project is compiled as C++17.
  • If you re-name a method include the id from the original method name as this makes it easier to track changes from the generated code. e.g. void sub_19CA0_sound_proc5(unsigned __int8 a1) was renamed to void ChangeSoundLevel_19CA0(uint8_t option)
  • Please follow the general style of the refactored code. Upper Camel Case (Pascal Case) for Class/Method names. Camel Case for variables. 'm_' for class members. GameRenderHD.cpp is a good example of the style.
  • Where possible (if writting new code) please use the fixed width types. https://en.cppreference.com/w/cpp/types/integer
  • For each commit please use the Semantic Commit Messages: https://gist.github.com/joshbuchea/6f47e86d2510bce28f8e7f42ae84c716
  • Be careful with making logic changes to the code and Test, Test, Test! I recommend playing the first level all the way though. Then the first Cave level (4) and I also recomend Level 5 as you have a nice mix of AI to kill and a cutscene at level completion.
  • Please build and run the remc2-regression-test project BEFORE making a pull request. This must pass and since it needs the game data cannot be placed in the Github Actions.
