    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.

    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.

    DeSmuME

    DeSmuME

    DeSmuME is a Nintendo DS emulator

    In this version we have added support for high-resolution 3D rendering. Try the new “GPU Scaling Factor” feature to increase the 3D resolution beyond the native resolution of 256×192 pixels. Also, the Cocoa frontend sees continued radical enhancements and while the Windows frontend sees some new incremental enhancements. DeSmuME is a very CPU demanding app. While many users will see DeSmuME as a toy (and use it as such), it is actually a very sophisticated piece of software with lots of features. Also, DeSmuME focuses more on compatibility and features than on speed. Our philosophy is this: You can always mow some extra lawns or babysit some more rugrats to buy upgrades for your computer; but there's nothing you can do to fix compatibility or gain new features. We take care of our side of things, so you should take care of yours. DeSmuME is mostly CPU intensive and less GPU intensive.

    nxdumptool

    nxdumptool

    Generates XCI/NSP/HFS0/ExeFS/RomFS/Certificate dumps from Switch

    Generates XCI/NSP/HFS0/ExeFS/RomFS/Certificate/Ticket dumps from Nintendo Switch gamecards and installed SD/eMMC titles. This branch is used for the development of the ongoing nxdumptool rewrite. Code is highly experimental and lacks a proper UI at this time, but it has been thoroughly tested and should be safe to use. Proof-of-concept (PoC) builds are provided to test different aspects of the codebase. If a nxdumptool build from the releases page isn't working for whatever you're trying to do (e.g. RomFS dumping), odds are it will work with a PoC build from this particular branch. The old branch will not receive any further updates. A GitHub workflow is used to automatically build each new commit. Individual NCA FS section dumps (select and dump a specific FS section from a specific NCA belonging to a title, in both extracted and raw image forms) (this includes patched RomFS images).

    Zelda 64: Recompiled

    Zelda 64: Recompiled

    Static recompilation of Majora's Mask for PC

    Zelda 64: Recompiled is a specialized recompilation project built on top of N64Recomp, focused on reconstructing The Legend of Zelda: Ocarina of Time and related N64 titles into native, compilable code for modern systems. It takes original game binaries and translates them into structured C code that can be compiled and run without requiring an emulator, enabling more efficient execution and deeper access to the game’s internals. The project is designed to preserve gameplay accuracy while providing opportunities for enhancement, including graphical improvements, performance optimizations, and expanded modding capabilities. By leveraging the N64Recomp framework, it benefits from a standardized approach to static recompilation while tailoring the process to the specific architecture and behavior of Zelda titles.

    ioquake3

    ioquake3

    The ioquake3 community effort to continue supporting/developing id's

    ioquake3 is a free and open source first-person shooter engine derived from the Quake 3: Arena and Quake 3: Team Arena source code, maintained as a modern baseline engine for new games and classic mods. It is designed to let players run Quake 3, its expansion Team Arena, and community mods on contemporary systems while also serving as a solid base for new projects. The engine modernizes the original codebase with a CMake build system, an SDL2 backend for cross-platform windowing and input, and OpenAL sound for better audio quality and multi-speaker setups. It adds numerous quality-of-life improvements such as VoIP support, AVI demo capture, improved console completion and history, and optional Ogg Vorbis support. ioquake3 also improves portability and maintainability by supporting x86_64 on Linux, MinGW builds on Windows, and various other operating systems, and even provides web support via Emscripten.
