    Mobilinux - Linux for Android

    Mobilinux - Linux for Android

    This application will allow you to install and run Linux on Android !

    The app supports ROOTED as well as NOROOTED devices. Use your mobile as a Pocket PC !! For Root Method: The application creates a disk image on a flash card, mounts it and installs an OS distribution. Applications of the new system are run in a chroot environment and working together with the Android platform. All changes made on the device are reversible, i.e. the application and components can be removed completely. Installation of a distribution is done by downloading files from official mirrors online over the internet. The application requires superuser rights (ROOT).Installing a new operating system takes about 15 minutes. The recommended minimum size of a disk image is 1024 MB (with LXDE), and without a GUI - 512 MB. Noroot Method: Install MOBICONSOLE addon and then install the linux on a non-rooted phone.

    FSearch

    FSearch

    A fast file search utility for Unix-like systems based on GTK3

    FSearch is a blazing-fast file search utility for Linux inspired by Windows’ Everything Search Engine, built to allow users to locate files and directories instantly by name rather than content. It achieves its high performance by indexing the filesystem and updating that index in real time, so as you create, rename, or delete files the results stay up to date without noticeable lag. The intuitive user interface supports incremental search — where results filter as you type — plus features like regular expressions, case-sensitivity options, and customizable indexing scopes, making it both powerful and accessible. Designed with GTK and written in C, it integrates nicely with desktop environments like GNOME, XFCE, and Cinnamon while still being lightweight and resource-efficient. Developers and power users appreciate FSearch for dramatically reducing the time it takes to find files compared to traditional search tools, especially on large partitions.

    Switch theme injector

    Switch theme injector

    Create custom themes for the Nintendo Switch

    The Switch theme injector project is split into three parts. Switch theme injector (Windows app): An app to create and edit custom themes. NXThemes installer: An homebrew app that runs on the switch itself and can be used to install and manage themes. Switch theme injector online (also called WebInjector): A port of the Windows injector as a web app, it lacks some features like custom applet icons and common.szs layouts support. The main objective is to develop a complete toolset to create and install custom themes on the switch. As the console os doesn't implement custom themes natively most of this is done by patching system SZS files to get the desired aspect. Unfortunately, SZS files from the switch os contain copyrighted data and can't be shared online that's why the nxtheme format has been developed, it contains only differential info and can be freely shared. Unless you're dealing with making your own patches and custom layouts you should only use nxtheme files.

    Windows File Manager

    Windows File Manager

    Original Windows file manager (winfile) with enhancements

    The Windows File Manager lives again and runs as a native x86 and x64 desktop app on all currently supported version of Windows, including Windows 10. I welcome your thoughts, comments and suggestions. There are two primary versions of the source code in the master branch, original_plus tag, which refers to the source for WinFile as of Windows NT4 with minimal changes so that it compiles with Visual Studio and runs on current Windows. And current master, which contains my personal changes / additions to WinFile. If you are running Windows 10, you can download the app from the store. If you just want to download the WinFile application without worrying about compiling from the source code, we have a number of precompiled versions available. The Windows File manager was originally released with Windows 3.0 in the early 1990s.

    nxdumptool

    nxdumptool

    Generates XCI/NSP/HFS0/ExeFS/RomFS/Certificate dumps from Switch

    Generates XCI/NSP/HFS0/ExeFS/RomFS/Certificate/Ticket dumps from Nintendo Switch gamecards and installed SD/eMMC titles. This branch is used for the development of the ongoing nxdumptool rewrite. Code is highly experimental and lacks a proper UI at this time, but it has been thoroughly tested and should be safe to use. Proof-of-concept (PoC) builds are provided to test different aspects of the codebase. If a nxdumptool build from the releases page isn't working for whatever you're trying to do (e.g. RomFS dumping), odds are it will work with a PoC build from this particular branch. The old branch will not receive any further updates. A GitHub workflow is used to automatically build each new commit. Individual NCA FS section dumps (select and dump a specific FS section from a specific NCA belonging to a title, in both extracted and raw image forms) (this includes patched RomFS images).

    PeerGuardian

    PeerGuardian - a privacy oriented firewall application

    PeerGuardian is a privacy oriented firewall application. It blocks connections to and from hosts specified in huge blocklists (thousands or millions of IP ranges). Its origin seeds in targeting aggressive IPs while you use P2P. PeerGuardian Linux: Not developed actively anymore. Team might still be around. Some unreleased changes on git. Outdated technology. Peerguardian OS X: Not developed anymore. We've lost contact with the OS X developer. PeerGuardian Windows: Not developed anymore. It's highly recommended to use PeerBlock instead, which is a continuation of PeerGuardian's development in Windows, with bug fixes and support for Windows Vista and Windows 7. Collaboration with peerblock.com is welcome! PeerGuardian is an open project. Not only is its source code open for you to read, use, and modify - but the project is open for you to join and contribute in any form (code, documentation, bug reports, web and support).
