    Brook

    Brook

    Brook is a cross-platform strong encryption and not detectable proxy

    Brook is a cross-platform strong encryption and not detectable proxy. Brook's goal is to keep it simple, stupid and not detectable. You can run commands after entering the command-line interface. Usually, everyone uses the command line interface on Linux servers. Of course, Linux also has desktops that can also run GUI. Of course, macOS and Windows also have command-line interfaces, but you may not use them frequently. Usually, the applications opened by double-clicking/clicking on macOS/Windows/iOS/Android are all GUIs. Usually, if you use Brook, you will need a combination of Server and Client, Of course Brook CLI also has many other independent functions. The Brook CLI file is an independent command file, it can be said that there is no concept of installation, just download this file to your computer, run it after granting it executable permissions in the command line interface.

    melonDS

    melonDS

    DS emulator, sorta

    melonDS aims at providing fast and accurate Nintendo DS emulation. While it is still a work in progress, it has a pretty solid set of features. Firmware boot (not direct boot) requires a BIOS/firmware dump from an original DS or DS Lite. DS firmwares dumped from a DSi or 3DS aren't bootable and only contain configuration data, thus they are only suitable when booting games directly. DS BIOS dumps from a DSi or 3DS can be used with no compatibility issues.

    Remix OS

    Remix OS

    Android OS for Windows PC systems

    Remix OS is a free Android version made by Jide, the company behind this operating system. This OS comes with certain basic Android features adding some missing functions that are present for Mac and Windows users. You install it on a USB and boot directly from that. It’s compatible with Intel and AMD processors, so it runs on almost any machine, and unlike other solutions, it has a dedicated desktop user interface just like the operating system you’re already used to. That means that when you open an app, it doesn’t take up the whole screen like it would on an Android tablet; it opens in its own window like any other desktop program. This allows you to use Chrome alongside Word, or Google Maps, or YouTube, or just about any other Android app. Remix OS is totally free to download and use. This is an alternative to running an Android Emulator for Windows.

    Live CD With Zerofree Utility i686 32Bit

    Live CD With Zerofree Utility i686 32Bit

    A Custom Puppy Linux Live CD With Zerofree Utility i686 32 Bit

    After Booting with this Live CD, just click on the CDROM icon on the Desktop, to open its folder contents, then Right Click the zerofree.sh file and Choose the "Run in Terminal" option and then follow the instructions shown on the terminal. As you may be aware, Booting with a Live CD, requires that you need to change the Boot Order on your System / Guest BIOS, quickly on startup, by pressing either F2 OR F12 OR F10 OR an equivalent key and then change the Boot Order to boot from the CDROM first. Some Hints: Puppy Linux Live CDs show some dialogs / settings window on first startup / first shutdown. Feel free to dismiss / close them, if you do not want to make any changes, to the live cd's operation, next time, on the same system. This will not affect the zerofree's work in any way. Apart from this, using the Internet Browser, built in, would require a Free Memory of 1 GB or more, for better Performance ( as it is generally a memory intensive activity )
