    Vectras VM

    Vectras VM

    It's a Virtual Machine App for Android Which is Based on QEMU

    Vectras VM Android is a mobile virtualization platform built on top of QEMU that enables users to run full desktop operating systems directly on Android devices. It functions as a complete virtual machine manager, allowing the emulation of systems such as Windows, Linux, macOS, and even other Android environments within a single app. The project is designed to push the limits of mobile hardware by leveraging modern smartphone CPUs and RAM configurations to simulate full computing environments. It includes a graphical interface and setup tools that simplify the process of creating and managing virtual machines, making it accessible beyond purely technical users. The emulator supports different architectures and integrates additional components like 3dfx wrappers to improve graphical compatibility and performance. Due to the heavy computational requirements, it is optimized for newer devices with high-end processors and sufficient memory.

    Xbpad

    Xbpad

    Xbpad - Use your xbox pad as keyboard and mouse.

    With Xbpad, you can use an Xbox 360® controller to surf the web and play games and music on your PC. It's a comfortable alternative to the keyboard and mouse. Using Xbpad with a wireless controller means you don't need to sit by your computer. You can control your music player wirelessly. You can also connect your computer to your TV and browse the web wirelessly using your controller. Xbpad lets you use a comfortable controller instead of the mouse and keyboard. If you find clicking a mouse difficult, squeezing a controller trigger might be a good alternative. If you need to stay away from the keyboard, you might like to try Xbpad instead. Download: Choose between application bundled with JRE or without.

    achtbit

    achtbit

    An 8 bit emulator created on the scratch, including an assembler.

    Ever had the experience of a 8 bit system, having max. 64k memory, using assembler to write effective small programs? This system is an experimental 8 bit, 16 color computer, with a processer similar to Z80, that (on my laptop using linux with NO opengl support) achieves up to 1.2 Million instructions per second and 50 Hz. screen refresh rate. It has a builtin assembler to load assembler programs. There is a rudimentary rom that implements some basic functions like line input, or a system clock. Also there is a snake game, (depending on that rom), as a reference and for fun! Take a look, give me your reply! When having ideas for better performance, let me know!

    psx4droid

    psx4droid

    PSX emulator for Android phones

    This project is based on sources published by original psx4droid developer (or someone else – I don't care as it is all GPLed anyway), who in turn used code of PCSX-ReARMed, forked from PCSX-Reloaded, based on PCSX-df and original PCSX... This project is abandoned in favor of libretro PCSX-ReARMed variant: https://github.com/libretro/pcsx_rearmed. Current sources already depend on recent version of platform anyway.
