    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.

    Roblox FPS Unlocker

    Roblox FPS Unlocker

    FPS Unlocker for Roblox

    FPS Unlocker for Roblox. Download the latest release, extract rbxfpsunlocker-x64.zip into a folder, run the exe before or after starting Roblox, and enjoy the beautiful frames available. All detections are false positives. Internally, RFU "tampers" with running Roblox processes in order to uncap framerate and can appear as suspicious to an anti-virus. For reasons unbeknownst to me, 32-bit builds of RFU garner many more false positive detections than 64-bit builds and are no longer included in new releases. If you don't trust me, feel free to download the repository, review the source code, and compile the project yourself with Visual Studio 2019. Otherwise, add an exception to your anti-virus for rbxfpsunlocker.exe (or the folder it is in).

    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.

    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.
