    Extreme Injector

    Extreme Injector

    DLL injector for gaming and other uses

    Extreme Injector is a software tool commonly used to inject Dynamic Link Libraries (DLLs) into other processes running on a Windows system. Often used in gaming and software development, this tool allows users to modify or add custom functionality to a target application by "injecting" DLL files, which can influence the application's behavior or provide additional features. Extreme Injector is popular in the gaming community for enabling modifications or "mods" in games, but it also has potential misuse in game cheating and malware deployment, as it allows for altering applications in ways the original developers may not have intended.

    Stockfish

    Stockfish

    UCI chess engine

    Stockfish is a free, powerful UCI chess engine derived from Glaurung 2.1. Stockfish is not a complete chess program and requires a UCI-compatible graphical user interface (GUI) (e.g. XBoard with PolyGlot, Scid, Cute Chess, eboard, Arena, Sigma Chess, Shredder, Chess Partner or Fritz) in order to be used comfortably. Read the documentation for your GUI of choice for information about how to use Stockfish with it. Stockfish is a 11-time winner of the Top Chess Engine Championship. Stockfish is open source (GPLv3 license). That means you can read the code, modify it, and contribute back. You can use Stockfish on your computer or on your iOS or Android device. So you can get world-class chess analysis, wherever you are. The Stockfish engine features two evaluation functions for chess, the classical evaluation based on handcrafted terms, and the NNUE evaluation based on efficiently updatable neural networks.

    Source Engine

    Source Engine

    Modified source engine (2017) developed by valve and leaked in 2020

    The Source Engine repository under that particular GitHub user appears to be a custom (or forked) version of a game engine — likely an engine derived from or inspired by the classic Source engine lineage (or at least the name evokes that lineage). However, publicly-available documentation, community support or clarity about the project’s scope and maturity seems limited: the repo does not clearly advertise a full engine release or wide adoption. As such, it feels more like an experimental or hobby project: potentially a work-in-progress engine or engine-in-progress reimplementation rather than a full production-ready game engine. For a developer, this means you're likely to face missing features, limited tooling, and the need to fill gaps yourself, but also that you have a chance to influence or shape the architecture as you develop.

    Citra

    Citra

    A Nintendo 3DS Emulator

    Citra is an experimental open-source Nintendo 3DS emulator/debugger written in C++. It is written with portability in mind, with builds actively maintained for Windows, Linux and macOS. Citra emulates a subset of 3DS hardware and therefore is useful for running/debugging homebrew applications, and it is also able to run many commercial games! Some of these do not run at a playable state, but we are working every day to advance the project forward. (Playable here means compatibility of at least "Okay" on our game compatibility list.) Citra is licensed under the GPLv2 (or any later version). Refer to the license.txt file included. Please read the FAQ before getting started with the project. If you want to contribute please take a look at the Contributor's Guide and Developer Information. You should also contact any of the developers in the forum in order to know about the current state of the emulator because the TODO list isn't maintained anymore.
