Can I play Diablo for free with Devilution?

No, Devilution requires the original game assets from a legitimate copy, such as from GoG.com. It only provides the source code, so you must own Diablo to use it legally.

How to compile Devilution on Linux?

Use MinGW64 by executing 'make' in the terminal, following the Linux installation guide in the docs. Ensure you have dependencies like g++ and required libraries installed for a successful build.

Is Devilution legal to use?

It exists in a legal gray area under DMCA exceptions for documentation and interoperability. While Blizzard hasn't taken action, there's potential risk, so use it cautiously for non-commercial purposes.

Devilution vs DevilutionX: which should I choose?

Choose Devilution for accurate source code preservation and modding the original game. Opt for DevilutionX if you want modern features like cross-platform support, bug fixes, and enhancements beyond the 1996 design.

How to add mods to Diablo using Devilution?

Modify the source code directly after compiling, as Devilution provides a stable base. Examples in the README show changes like monster lifebars, but you'll need C++ knowledge to implement and compile your mods.

Does Devilution support multiplayer on modern systems?

Yes, it supports multiplayer via GoG's Battle.net, IPX with a wrapper, and UDP using StarCraft's library. For global play, use tools like ZeroTier to connect UDP networks seamlessly.

What is Devilution?

Devilution is a reverse-engineered reconstruction of the original 1996 Diablo game's source code, pieced together from debug symbols and hidden builds. It provides an open, accurate codebase for studying, maintaining, and modding the classic game while preserving its original design and bugs.

Target Audience

Game developers, modders, and preservationists interested in Diablo's internals, classic game reverse-engineering, or creating mods and ports for the original game.

Value Proposition

It offers the only publicly available, fully documented source code for Diablo, enabling easier maintenance, cross-platform porting, and community modding compared to tedious memory injection or private reverse-engineering efforts.

Porting Diablo to modern platforms and operating systems

Preserving and documenting classic game development techniques

Exploring cut content and unused features from Diablo's development

Learning reverse-engineering techniques from a completed game project

Not Ideal For

Players wanting modern graphics upgrades like 1080p support or new visual effects
Developers seeking a standalone game without needing original Diablo assets (diabdat.mpq)
Commercial projects aiming to sell mods or derivatives (due to non-commercial license)
Teams prioritizing a simple, out-of-the-box build process with minimal setup

Pros & Cons

Pros

Accurate Source Reconstruction

Provides a fully documented, compilable version of Diablo's original source code, reverse-engineered from debug symbols and hidden builds, enabling deep study and modification.

Historical Preservation

Maintains original code, bugs, and design as a faithful reference, documenting cut content from Diablo's rushed development for archival purposes.

Multiplayer Compatibility

Supports GoG's Battle.net, IPX via wrapper, and UDP using StarCraft's library, offering flexible multiplayer options beyond the original game.

Cross-Platform Builds

Can be compiled with Visual C++ 6, modern Visual Studio, or MinGW on Windows, Linux, and Mac, facilitating porting to modern systems.

Modding Foundation

Enables easier creation of mods, such as monster lifebars and new trade screens, with a stable code base compared to memory injection methods.

Cons

No Modern Features

Deliberately excludes enhancements like 1080p support; for updates, users must fork to DevilutionX, which splits community efforts and requires additional work.

Complex Compilation Setup

Requires specific tools like Visual C++ 6 with Service Pack 5 and Processor Pack, and has dependencies that can be tricky to configure, as noted in the build instructions.

Legal Gray Area

Exists in a copyright gray zone under DMCA exceptions, which might deter risk-averse users or attract legal attention from Blizzard, as mentioned in the F.A.Q.

Requires Original Assets

Needs an original copy of diabdat.mpq and other files, not providing any game assets, which adds a barrier to entry and relies on external purchases.

Zelda3

Zelda3 is a complete reimplementation of the classic SNES game *The Legend of Zelda: A Link to the Past* in C, comprising approximately 70-80k lines of code. It faithfully replicates the original game's logic and behavior while enabling verification through side-by-side execution with the original machine code. This project makes the game accessible on modern platforms and allows for community-driven improvements and modifications. ## Key Features - **Complete Game Reimplementation** — All parts of the original game are recreated in C, making it playable from start to end. - **Verification System** — Can run original machine code alongside the C implementation to compare RAM states each frame for accuracy. - **Modern Enhancements** — Adds features like pixel shaders, 16:9/16:10 aspect ratios, higher-quality world maps, and MSU audio track support. - **Quality-of-Life Improvements** — Includes a secondary item slot on button X, item switching with L/R keys, and snapshot-based replay functionality. - **Cross-Platform Support** — Compiles and runs on Windows, Linux, macOS, and even Nintendo Switch with appropriate toolchains. ## Philosophy The project prioritizes accuracy and verification, ensuring the C implementation behaves identically to the original SNES game while thoughtfully adding modern features that enhance the experience without compromising authenticity.
