    QToaster

    A simple and fast frontend for the QEMU Emulator - Freeware.

    QToaster is a simple app that executes QEMU with proper command line parameters (a frontend). The features are pretty basic, the executable is small and is a portable application. I needed something to automate QEMU quickly operate fast without having to worry about setting things up. I just wanted to get moving fast. It is designed just for that. It will keep your last machine settings and reload them from the .ini files that it creates. The main purpose I needed this for is Android - using Limbo. If something works on QEMU then it has a good chance of working on Android. You don't need to put QEMU in your environment path, just point to its base folder. It doesn't need any special runtimes (java, .net, Python, etc.), it only needs the utility file Lutil.dll. Frontend was made for: http://69.170.215.148/nothoro/software/QTPage/QToaster.html QEMU emulator version 6.0.0-rc2 available at: https://qemu.weilnetz.de/w64/2021/ When you run the installer, it will extract to a subfld

    MLCrypt

    Simple, lightweight, standalone command-line single file encryption.

    Simple, lightweight, cross-platform (Windows / Linux / ARM6 Linux), cross-arch (x32 / x64), standalone command line file encryption program. GnuPG is probably the best application for cross-platform encryption. However, its usage on Windows PCs may be inconvenient (installation administrator rights; large executable size for perhaps just a one-time file decryption, complicated command-line switches for stronger encryption). NCrypt would fulfill this task, but does not operate on 64-bit Windows - MLCrypt was created because of this. The program's primary aim is cascade encryption: create an encrypted outer layer over an existing compressed and encrypted archive file. (Each encryption layer should have a different complex password.) MLCrypt.zip contains all the executables: Linux, Windows, Raspberry Pi.
