    Wurst Client

    Wurst Client

    Minecraft Wurst Hacked Client v7

    Wurst7 is an open-source modified Minecraft client that includes a large collection of gameplay modifications commonly referred to as “hacks” or cheat modules. The project provides a custom client environment where players can enable various automated tools, overlays, and gameplay enhancements that alter how the game behaves. These features may include movement enhancements, automation utilities, and visualization tools that provide additional information about the game world. Wurst7 is typically installed as a Fabric mod and runs alongside the standard Minecraft Java Edition client.

    FernFlower

    FernFlower

    Decompiler from Java bytecode to Java, used in IntelliJ IDEA

    Fernflower is an open-source Java decompiler originally developed by JetBrains that takes compiled Java bytecode and reconstructs readable source code, helping developers understand, debug, and recover lost Java code from .class files. It works by analyzing the structure of bytecode and inferring higher-level constructs like loops, conditionals, generics, and exception handling to produce Java source that is as close as possible to what a human would have written, making it useful for both reverse engineering and educational purposes. Fernflower is integrated into popular Java IDEs and tools where decompilation is needed, and its robust analysis handles a wide range of language features introduced across multiple Java versions. Because it outputs clean, structured, and often compilable code, developers use it for auditing binaries, exploring third-party libraries without source, and recovering parts of legacy systems where source was lost or unavailable.

    Magisk Manager

    Magisk Manager

    Companion Android application for Magisk

    Magisk Manager is the companion Android app historically used to manage the Magisk root solution—installing updates, toggling modules, configuring DenyList/Hide-like behavior, and passing device integrity checks where possible. It centralizes operations that would otherwise require flashing or command-line work, making root management accessible to power users and developers. The app surfaces module repositories, logs, and safety features, giving you insight into what’s modified and how it affects system behavior. Over time, its role evolved alongside Android’s changing security model, but the core idea remains: provide a clean UI for patching, updating, and managing a systemless root environment. It also acts as a troubleshooting hub, exposing diagnostics that help users resolve boot loops or module conflicts. For anyone maintaining a rooted device for legitimate development and customization, Magisk Manager is the operational control center that keeps the stack coherent.

    NoiseGator (Noise Gate)

    NoiseGator (Noise Gate)

    A simple noise gate app intended for use with VOIPs like Skype.

    Ever wanted to cut out background noise when talking with others on Skype? Now it's possible! NoiseGator is a light-weight noise gate application that routes audio through an audio input to an audio output. In real-time the audio level is analysed and if the average level is higher than the threshold the audio bypasses as normal. However, if the average level goes below the threshold, the gate closes and the audio is cut. When used with a virtual audio cable it can act as a noise gate for a either a sound input(microphone) or sound output(speakers). Can also be used to gate noise from your own mic or play your microphone through your speakers. REQUIREMENTS: - Java 7 or higher for Windows. - Java 6 or higher for Mac. Java 7 recommended. - A virtual audio cable is required for use with VOIPs: For Windows users I recommend the VB-Cable driver (http://vb-audio.pagesperso-orange.fr/Cable/index.htm). Mac users can use SoundFlower.

    KonaBess

    KonaBess

    A GPU overclock & undervolt tool for various Snapdragon chips

    KonaBess is a straightforward application designed to customize GPU frequency and voltage tables without the need for kernel recompilation. The application achieves customization by unpacking the Boot/Vendor Boot image, decompiling and editing relevant dtb (device tree binary) files, and finally repacking and flashing the modified image. The extent of improvement varies, with some users reporting a 25% reduction in power consumption in the graphics benchmark (4.2w->3.2w) after undervolting the Snapdragon 865. Actual improvement is chip-specific and contingent on stability requirements.
