Diablo build for modern operating systems

How To Play:

• Copy diabdat.mpq from your CD, or GoG install folder, to the DevilutionX game directory ; Make sure it is all lowercase.
• Download DevilutionX, or build from source
• Install SDL2 (including SDL2_mixer and SDL2_ttf) make sure to get the appropriate 32bit or 64bit version.
• Run ./devilutionx

Building devilutionX (native Linux build)

Note: Since 64-bit builds are currently not in a playable state, it is advised to build in a 32-bit environment. Another possibility is a 32-bit build on a multilib system (see below).

Install the dependencies on your machine:

sudo apt-get install cmake g++ libsdl2-dev libsdl2-mixer-dev libsdl2-ttf-dev libsodium-dev

Now run the following commands:

mkdir build
cd build
cmake ..
make -j$(nproc)

Arguments to cmake:

The default build type is Debug. This can be changed with -DBINARY_RELEASE=ON. Independently of this, the debug mode of the Diablo engine is always enabled by default. It can be disabled with -DDEBUG=OFF. Finally, in debug builds the address sanitizer is enabled by default. This can be disabled with -DASAN=OFF.

To run the game:

• Copy the compiled devilution executable to your Diablo directory.
• Copy the "diablodat.mpq" from your Diablo CD to the Diablo directory and make sure it is LOWERCASE.
• Run ./devilution

Please keep in mind that this is still being worked on and is missing parts of UI and SoundEffects are not properly playing now.

Building deviltuionX 32-bit on 64-bit Linux (multilib) platforms

Install the dependencies on your machine:

sudo apt-get install cmake g++-multilib libsdl2-dev:i386 libsdl2-mixer-dev:i386 libsdl2-ttf-dev:i386 libsodium-dev libsodium-dev:i386

Now run the following commands:

mkdir build
cd build
linux32 cmake -DCMAKE_TOOLCHAIN_FILE=../CMake/32bit.cmake ..
linux32 make -j$(nproc)

Cross-compiling for Windows via MinGW

Install the dependencies on your machine:

Download and place the 32bit MinGW Development Libraries of SDL2, SDL2_mixer, SDL2_ttf and Libsodium in /user/i686-w64-mingw32.

sudo apt-get install cmake gcc-mingw-w64-i686 g++-mingw-w64-i686

Use -DCROSS_PREFIX=/path/to/prefix if the i686-w64-mingw32 directory is not in /usr.

Now run the following commands:

mkdir build
cd build
cmake -DASAN=OFF -DCMAKE_TOOLCHAIN_FILE=../CMake/mingwcc.cmake ..
make -j$(nproc)

Building devilutionX on macOS

Building with Xcode Build (x86 only)

Install Xcode 9.4.1 and Xcode Command Line tools, this is the last version with support for 32 bits

Note: Be sure that your to select the command line Xcode if you have two or more installed, for example:

$ sudo xcode-select --switch /Applications/Xcode.app

Install the some tools using Homebrew:

brew install automake autoconf libtool

Get and build the dependencies

$ ./xcode-build.sh --get-libs --build-libs

Build the devilutionX project

$ ./xcode-build.sh --build-project

The result bundle should be in the build folder

To create a dmg execute

$ ./xcode-build.sh --package

If you want use Xcode to build and debug, you can find the project inside Xcode folder

Building for x64 with CMake

Note: macOS is 64-bit only so this is not fully playable at this point.

Install the dependencies using Homebrew:

brew install cmake sdl2_mixer sdl2_ttf libsodium pkg-config

Now run the following commands:

mkdir build
cd build
cmake ..
make -j$(sysctl -n hw.physicalcpu)

Installing

Once compiled, the devilutionx binary will serve as a replacement for Diablo.exe. The following files from the original game patched to 1.09(b) need to be present: diabdat.mpq. If COPYPROT was defined when compiling, the Diablo CD will also be required.

Multiplayer

• TCP/IP only requires the host to expose port 6112
• UPD/IP requires that all players expose port 6112

All games are encrypted and password protected.

Modding

Here are some screenshots of a few things I tinkered around with, to demonstrate the relative ease of improving the game:

F.A.Q.

Wow, does this mean I can download and play Diablo for free now?

No, you'll need access to the data from the original game. To get a legitimate copy of the game assets, please refer to the GoG release of Diablo 1.

Ok, so I'm playing DevilutionX now and all the sudden it crashed. NOW WHAT??

Open an issue and provide as much information as possible (OS version, etc.) including any crash logs.

I thought I'd fix the crash myself, but after looking at the code its a disaster. Do you speak v2-34-v8?

That is the result of decompiled code. Whenever a program is compiled, much of the source is optimized and stripped away, so it's nearly impossible to decompile it back. Have patience. Everything will be cleaned up eventually. :)
