Open Source C Virtual Machine Software

Brings Erlang, Elixir and other functional languages to really small systems. AtomVM implements from scratch a minimal Erlang VM that supports a subset of ErlangVM features and that is able to run unmodified BEAM binaries on really small systems like MCUs. There is much more information, including a more complete "Getting Started Guide," extensive documentation, examples, and contact information available on the AtomVM project website. AtomVM aims to be easily portable to new platforms with a minimum effort, so additional platforms might be supported in a near future. AtomVM is still in its early stages, but it can run simple applications similar to those available in examples and tests. This basically means that an instruction has not been implemented yet, or that an outdated version has been used. Please, make sure to always run AtomVM using latest version.

kvm, or kernel-based virtual machine, is a device driver and userspace component for Linux that utilizes hardware virtualization extensions such as Intel's VT to create virtual machines running on a Linux host.

X11-Basic is a dialect of the BASIC programming language with graphics capability that integrates features like shell scripting, cgi-Programming and full graphical visualisation into the easy to learn basic language on modern computers.

crosvm (ChromeOS Virtual Machine Monitor) is a secure, lightweight virtual machine monitor built on top of the Linux KVM hypervisor. Developed for ChromeOS, it is designed to isolate and execute Linux and Android guests efficiently while maintaining strong security boundaries. Unlike general-purpose emulators like QEMU, crosvm avoids full hardware emulation and focuses on modern paravirtualized I/O using the virtio standard, reducing complexity and attack surface. Written in Rust, it emphasizes memory safety and modularity, allowing sandboxed device emulation with fine-grained privilege separation. crosvm underpins several ChromeOS subsystems, including Android Runtime for Chrome (ARCVM) and Crostini Linux containers, enabling rich application compatibility within a tightly controlled environment.

A PSP porting of SUN's phoneMEFeature (https://phoneme.dev.java.net/) project, to enable MIDP/JavaME applications running on PSP. You can also find phoneMEAdvanced PSP porting from another project: pspME(https://sourceforge.net/projects/pspme)

The open-vm-tools project provides a suite of open source virtualization utilities and drivers to improve the functionality and user experience of virtualization. The project currently runs in guest operating systems under VMware virtualization.

TiEmu is an emulator of Texas Instruments hand-helds (TI89/92/92+/V200) for Linux & Windows written with GTK. Full-featured with a graphical debugger.

BitVisor is a tiny hypervisor initially designed for mediating I/O access from a single guest OS. Its implementation is mature enough to run Windows and Linux, and can be used as a generic platform for various research and development projects.

The Ring is a practical general-purpose multi-paradigm language. The supported programming paradigms are imperative, procedural, object-oriented, declarative using nested structures, functional, meta programming and natural programming. The language is portable (MS-DOS, Windows, Linux, macOS, Android, WebAssembly, Microcontrollers, etc.) and can be used to create Console, GUI, Web, Games and Mobile applications. The language is designed to be simple, small and flexible. Ring is distributed as a Free-Open Source project under the MIT License.

The user-mode kernel port is a port of the Linux kernel which runs in a set of processes. The result is a user-mode virtual machine and a kernel which can be debugged and developed using all of the usual process-level tools.

GXemul is a full-system computer emulator, emulating processors (ARM, MIPS, M88K, PowerPC, and SuperH) and surrounding peripherals, in some cases well enough to let unmodified guest operating systems run as if they were running on real hardware.

Yet another Tetris clone. It features up to 4 simultaneous players, 5 customizable play modes, a piece editor and player profiles (high scores and statistics). Customizable skin, music and background

Tcl9 is an umbrella for all projects related to the improvement of the current Tcl language, towards the hypothetical version 9 (current version is 8.5).

vmdkutil is a utility to manage VMware sparse virtual disk files (.vmdk), creating, cloning, merging, etc.

SableVM is a clean-room, highly portable and efficient Java virtual machine. Its goals are to be reasonably small, fast, and compliant with the various specifications (JVM specification, JNI, invocation interface, etc.).

URBI: Universal Robotic Body Interface. URBI is a scripted command language used to control robots (AIBO, pioneer,...). It is a robot-independant API based on a client/server architecture. Liburbi C++/Java/Matlab are available here. Forum available at ht

This program emulate the Sega's System 16 arcade boards used by many Sega arcade game between 1987 & 1989 like Shinobi, Altered Beast or E-Swat. There is more than 20 existing System 16 games. The System 16 board uses a Motorola 68000 cpu at 10Mhz for the main program and a Z80 and on YM2151 for the sound. The actual version of the emulator emulate many more than the single System 16 board because now you can play with System 18 games like Shadow Dancer, with pre-System 16 games like Quartet II and even with some dual 68000 games like Hang-On and Space Harrier. This program is an emulator and it needs roms to run, please, don't e-mail be to get roms, i'll ignore your requests !

Clipper/XBase compatible compiler with initial support other xBase dialects. Multitasking, OOP,SIX/Comix, SQL and ODBC drivers,a C-API for third-party developers, a few wrappers for popular libraries (such as BZIP, GZIP, GD, Crypto, and Fcgi), ....

The goal of this project is to develop a block I/O bandwidth controller on Linux.

The Virtual Motherboard provides a specification of a TCP/IP based system bus, a motherboard simulator implementing this specifaction, and a collection of reusable device simulators. It is the perfect start to build new custom hardware simulators.

My changes to qemu for legacy free GPU passthrough. Only one adapter can use legacy vga regions at same time. This is an attemp to achieve a qemu gpu passthrough without legacy vga accesses to graphics card. Legacy io accesses to vga registers are replaced through MMIO accesses. Legacy accesses to vga memory are replaced through accesses to plain framebuffer. This avoids vga arbiter problems in linux kernel.

Jainja is a JVM (Java Virtual Machine) written in Java. The VM is developed by using the smallest possible subset of Java in order to run on top of multiple environments : Java SE, JavaME, Android, Javascript, and even natively.

We will create seperate computing environments by Virtualising the native operating system with each environment acting as a dedicated server.Each environment (or VPS) act as different server with different network and files and processes.

Mac-on-Linux is a Linux/PPC program that virtualizes MacOS or MacOSX in Linux.

OS9exec - execution environment for OS-9/68k user-mode programs on MacOS9 / MacOSX / Windows and Linux host OS. (OS-9 is an RTOS of Microware/Radisys)
