    vJoy
    This project was originally designed to provide an open-source replacement for PPJoy. The product, at this point, consists of virtual joystick devices that is seen by the system as a standard joystick but its position-data is written to it by a feeder application. An existing feeder application that takes advantage of this product is SmartPropoPlus. If you are an application writer you can very easily write an application that controls a joystick (e.g. mouse-to-joystick, keyboard-to-joystick). If you are a beginner in device drivers you can take this code and enhance it to support more (or less) axes, buttons or POVs.

    Xash3D FWGS Engine

    Xash3D FWGS Engine

    Xash3D FWGS engine

    Xash3D FWGS is an open-source fork and extension of the original GoldSrc-based engine (from the classic era of first-person shooters), aimed at providing compatibility with the original engine (e.g. games built on it) while extending and modernizing its capabilities. The engine supports multiple rendering backends (OpenGL, GLES, software fallback), modern platforms (desktop OSes, mobile, etc.), and updated features such as better multiplayer, voice chat, IPv6 support, improved virtual filesystem, and support for modern asset formats. For modders or fans of classic games, Xash3D FWGS offers a way to play or build games using the familiar GoldSrc workflow but with updated portability and features. Legacy mods and maps for supported games can often be used unchanged (or with minimal modifications), preserving the classic experience. At the same time, the engine’s enhancements — modern input support (gamepad, touch), modern OS compatibility, cross-platform builds.

    Quake III Arena

    Quake III Arena

    Quake III Arena GPL Source Release

    Quake-III-Arena is the legendary first-person shooter originally released in 1999, and this repository holds its GPL-licensed source code release. By making the engine code fully open under GPL-2.0 (with licensing details regarding some bundled libraries like zlib), it allows the community to build, port, and maintain the engine, ensuring that the game remains playable even decades later. The release includes all major game subsystems: rendering, physics, network code, game logic, and tools (map compilation, asset packing, etc.), enabling full builds on Windows, Linux, macOS — assuming you provide the original game assets. Because the source is available, there are many community forks and improved engine builds (and ports) that modernize graphics, compatibility, input, mod support, and add enhancements while preserving core gameplay. The GPL-based release also enables modders and developers to study and extend the engine for learning, custom mods, or even entirely new games.
