    Multi Theft Auto: San Andreas

    Multi Theft Auto: San Andreas

    Multi Theft Auto is a game engine

    Multi Theft Auto (MTA) is a software project that adds network play functionality to Rockstar North's Grand Theft Auto game series, in which this functionality is not originally found. It is a unique modification that incorporates an extendable network play element into a proprietary commercial single-player PC game. Multi Theft Auto is based on code injection and hooking techniques whereby the game is manipulated without altering any original files supplied with the game. The software functions as a game engine that installs itself as an extension of the original game, adding core functionality such as networking and GUI rendering while exposing the original game's engine functionality through a scripting language. Originally founded back in early 2003 as an experimental piece of C/C++ software, Multi Theft Auto has since grown into an advanced multiplayer platform for gamers and third-party developers.

    libGDX

    libGDX

    Desktop/Android/HTML5/iOS Java game development framework

    libGDX is a cross-platform Java game development framework based on OpenGL (ES) that works on Windows, Linux, macOS, Android, your browser and iOS. libGDX provides a well-tried and robust environment for rapid prototyping and fast iterations. libGDX does not force a specific design or coding style on you; it rather gives you the freedom to create a game the way you prefer. Publish your games on Windows, macOS, Linux (including the RPi!), Android, iOS, and HTML5, all with the same code base. libGDX comes with batteries included. Write 2D or 3D games and let libGDX worry about low-level details. Heavy emphasis is put on avoiding garbage collection for ART/JavaScript by careful API design and the use of custom collections. libGDX is a well proven and reliable framework with a sound base and documentation. Furthermore, there are plenty of games built on top of libGDX, many of which are open source.

    Speed Dreams : an Open Motorsport Sim
    2025 UPDATE: we have finally moved to Git! https://forge.a-lec.org/speed-dreams/speed-dreams-code/ This SourceForge project will be kept as a read-only archive and will be eventually removed! Speed Dreams is a Motorsport Simulator featuring high-quality 3D graphics and an accurate physics engine, all targeting maximum realism. Initially forked from TORCS, it has now reached a clearly higher realism level in visual and physics simulation, thanks to its active development team and growing community. It mainly aims to implement exciting new features, cars, tracks and AI opponents to make a more enjoyable game for the player, while constantly pushing forward visual and physics realism. It is also intended for any research, study or teaching activity, around physics and AI, thanks to its GPL V2+ license, and the clear and modular architecture of its C/C++ code base.

    Pyrite64

    Pyrite64

    N64 Game-Engine and Editor using libdragon & tiny3d

    Pyrite64 is an open-source Nintendo 64 game engine and editor built using libdragon and tiny3d, designed to help developers create homebrew N64 games with modern tooling while still targeting the original hardware. The project provides both runtime engine components and an accompanying editor environment to streamline asset management and scene construction for retro console development. It focuses on lowering the barrier to entry for N64 homebrew by wrapping low-level graphics and hardware interactions into more approachable abstractions. Because developing for the N64 typically requires deep hardware knowledge, pyrite64 aims to provide a more ergonomic workflow while still preserving performance suitable for real hardware. The engine supports building and running projects in authentic N64 environments, making it attractive for hobbyists, retro enthusiasts, and preservation-minded developers.

    Redot Engine

    Redot Engine

    Multi-platform 2D and 3D game engine

    Redot Engine is an open-source game engine that aims to provide a flexible foundation for building games — likely offering a modern, modular structure so developers can compose only the systems they need (rendering, physics, input, scripting, etc.). It is built to give a base framework rather than a full “batteries-included” engine, which makes it suitable for developers who prefer minimalism, want complete control over architecture, or desire to build custom workflows. Because it’s open-source, Redot-Engine is potentially community-driven, allowing anyone to inspect, extend, or customize core functionalities. Its modularity and open nature make it attractive for indie developers or hobbyists who want to avoid heavyweight engines with lots of built-in assumptions. Even if the engine may not yet rival more mature engines in features or polish, its openness and design philosophy can offer an appealing balance between simplicity and flexibility.

    Luanti

    Luanti

    Voxel game-creation platform with easy modding and game creation

    Luanti, originally known as Minetest, is a free, open-source voxel game engine and platform designed to let players, modders, and developers build and play diverse sandbox-style 3D worlds. Written in C++ for core performance and Lua for scripting, Luanti runs on multiple operating systems (Windows, macOS, Linux, BSD variants and even Android), making it highly accessible and cross-platform. Rather than being a single game, Luanti is meant as an engine and toolkit: individual “games” are actually collections of mods — written in Lua — that define terrain, items, NPCs, mechanics, and rules. This modular design enables rich customization and community-driven content: users can install new games, mods, and texture packs via a built-in content browser that draws from a central repository (ContentDB). Luanti supports both single-player and multiplayer via servers; players can host their own or join publicly listed ones, with server-side mods being applied automatically.

    AviTab

    AviTab

    X-Plane plugin that displays a tablet to aid VR usage

    AviTab is a plugin for the X-Plane flight simulator. It displays a tablet-like computer with a few apps in the cockpit. It is mainly used for flying in virtual reality. When flying in a simulator, one often needs to look up details in PDF charts, plane manuals, checklists or other documents. Using a PDF reader breaks the immersion because the virtual aviator either has to take off of their HMD or use other tools that can move windows into VR. AviTab tries to solve this problem by offering a PDF reader inside a native plugin for X-Plane. Using a plugin also opens possibilities for more apps inside the tablet, for example, to display information about the plane status or aid in navigation. When hovering over the edges of the tablet from a short distance, X-Plane will display green bars around the tablet. The upper bar can be used to grab the window and move it around inside the cockpit.

    Unleashed Recompiled

    Unleashed Recompiled

    An unofficial PC port of the Xbox 360 version of Sonic Unleashed

    Unleashed Recompiled is a reverse engineering and recompilation project aimed at reconstructing Sonic Unleashed for modern platforms by translating original console binaries into readable and rebuildable C++ code. Instead of emulating the game, the project focuses on decompilation and recompilation, allowing the game to run natively on modern hardware with improved performance and compatibility. It works by analyzing the original Xbox 360 or PlayStation 3 binaries and recreating equivalent source code that can be compiled using modern toolchains. This approach enables developers to modify, optimize, and extend the game in ways that are not possible through traditional emulation. The project is part of a broader effort within the Hedge-dev community to preserve and modernize Sonic titles through open-source tooling and reverse engineering techniques. It also lays the groundwork for future enhancements such as modding support, graphical improvements, and platform portability.
