Blooket Cheats
05k0nz's legacy is safe
Blooket-Cheats is a repository containing scripts and a small web interface for Blooket game modifications. It organizes cheat scripts by game mode and provides methods for loading them through bookmarklets, a GitHub Pages interface, or browser console execution. The repository includes folders for cheats, tutorials, auto-update logic, page styling, and front-end code. From a software perspective, it is a browser-script collection focused on manipulating a web game environment. However, using cheats can violate platform rules, undermine fair play, and create problems in classroom or competitive settings. It is best described neutrally as a JavaScript-based browser scripting repository rather than as a recommended gameplay tool. -

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. -

x360ce (Xbox 360 Controller Emulator)
x360ce allows your controller to function as an Xbox 360 controller
x360ce, or Xbox 360 Controller Emulator, is a Windows utility that lets many gamepads, joysticks, wheels, and other controllers behave like an Xbox 360 controller. It is mainly used for PC games that support XInput controllers but do not properly recognize older or non-Xbox DirectInput devices. Older versions worked by placing configuration and DLL files inside a game folder, while version 4 uses a virtual Xbox 360 controller driver while the app keeps running. The project includes the emulator application, supporting libraries, front-end tools, configuration logic, and controller mapping features. It can help users map buttons, triggers, sticks, POV inputs, and wheel controls to the layout expected by games. x360ce is useful for players who want broader controller compatibility without replacing their existing hardware. -

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.

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). -
