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. -

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. -

Citra Emulator
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. -

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. -

AIMi AI Aimbot
AIMi its an AI aimbot, it work by real-time object detection
AIMi is a Python-based AI aim-assist experiment that uses real-time object detection to identify human-like shapes in game footage. It is built around neural network detection and OpenCV processing rather than direct modification of game files. The project presents itself as a beta implementation, with current behavior depending heavily on processor performance, model accuracy, and screen conditions. It includes a simple object-detector interface so users can see how the system recognizes targets during testing. The repository describes a CPU-heavy version with limited GPU usage and notes plans for faster GPU-oriented improvements. Because it is designed around game targeting behavior, it should only be discussed and used in authorized, accessibility-focused, private, or noncompetitive environments. -

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.

Prodigy Hack
One of the best Prodigy hacks
Prodigy Hack is a browser-based or script-driven modification tool designed to alter gameplay behavior in the Prodigy Math Game by manipulating client-side logic and data handling. It allows users to modify in-game variables such as player stats, currency, progression, and other gameplay elements through injected scripts or browser console commands. The project demonstrates how web-based educational games can be influenced through client-side execution, exposing limitations in input validation and state management. It is typically implemented as a collection of scripts that can be executed in real time while the game is running, enabling immediate changes without modifying server infrastructure. The tool is often used for experimentation, reverse engineering, or demonstrating vulnerabilities in browser-based applications. It also reflects broader concepts in web security, particularly the importance of server-side validation and secure state management. -

Pokémon: Evolved
All of the original 151 pokemon now have longer evolutions lines
Pokemon: Evolved is a ROM hack of Pokémon LeafGreen that significantly expands the original gameplay by redesigning evolution mechanics and extending the Pokédex. The project modifies all original Generation I Pokémon to include additional evolution stages, increasing the total number of obtainable creatures and creating a more complex progression system. It introduces custom sprites, new Pokédex entries, and shiny variants for the added evolutions, enhancing both visual and gameplay variety. Core mechanics such as stats, movesets, and evolution levels have been rebalanced to provide a more challenging and engaging experience. The hack also ensures that all Pokémon can be obtained within a single playthrough by adjusting encounter rates and availability across routes. Additional quality-of-life changes, such as infinite rare candies and simplified evolution requirements, streamline progression while maintaining difficulty. -

OptiScaler
OptiScaler bridges upscaling/frame gen across GPUs
OptiScaler is an open-source modding tool designed to enhance graphics performance and flexibility in modern PC games by allowing users to replace or modify built-in upscaling technologies. Instead of relying on the upscaling method originally integrated by a game developer, the software intercepts the game’s rendering pipeline and redirects it to alternative technologies chosen by the user. This makes it possible to swap technologies such as NVIDIA DLSS, AMD FSR, or Intel XeSS even if the game only supports one of them by default. The tool effectively acts as a compatibility layer between the game engine and multiple upscaling frameworks, enabling cross-GPU access to features that might otherwise be restricted to specific hardware ecosystems. In addition to replacing upscalers, OptiScaler can enable frame generation features in titles that do not officially support them, improving frame rates and perceived smoothness during gameplay. -

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). -
