ScummVM is a program which allows you to run certain classic graphical point-and-click adventure games, provided you already have their data files. The clever part about this: ScummVM just replaces the executables shipped with the game, allowing you ... [More] to play them on systems for which they were never designed! ScummVM lets you run these adventures: Adventure Soft's Simon the Sorcerer 1 and 2; Revolution's Beneath A Steel Sky, Broken Sword 1 and Broken Sword 2; Flight of the Amazon Queen; Wyrmkeep's Inherit the Earth; Coktel Vision's Gobliiins and games based on LucasArts' SCUMM (Script Creation Utility for Maniac Mansion) system. SCUMM is used for many games, including Monkey Island, Day of the Tentacle, Sam and Max and more. Compatibility with supported games is continually improving, so c [Less]

LLVM is a robust system, particularly well suited for developing new mid-level language-independent analyses and optimizations of all sorts, including those that require extensive interprocedural analysis. LLVM is also a great target for front-end ... [More] development for conventional or research programming languages, including those which require compile-time, link-time, or run-time optimization for effective implementation, proper tail calls or garbage collection. We have an incomplete list of projects which have used LLVM for various purposes, showing that you can get up-and-running quickly with LLVM, giving time to do interesting things, even if you only have a semester in a University course. We also have a list of ideas for projects in LLVM. [Less]

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.

FreeSCI is a portable interpreter for SCI games, such as the Space Quest series (starting with SQ3) or Leisure Suit Larry (2 and sequels).

Openc2e is a cross-platform open-source game engine designed to be compatible with and run the Creatures series of games, including Creatures 1, 2, 3 and Docking Station.

JamVM is a compact Java Virtual Machine conforming to the JVM specification edition 2 (blue book). It is extremely small; stripped executable on PowerPC ~180K, Intel 150K. However, unlike other small VMs it supports the full J2SE 1.5 specification, inc. soft/weak/phantom references, annotations and JNI.

Jikes RVM (Research Virtual Machine) provides a flexible open testbed to prototype virtual machine technologies and experiment with a large variety of design alternatives. The system is licensed under an OSI approved license. Jikes RVM runs on many ... [More] platforms and advances the state-of-the-art of virtual machine technologies for dynamic compilation, adaptive optimization, garbage collection, thread scheduling, and synchronization. A distinguishing characteristic of Jikes RVM is that it is implemented in the Java™ programming language and is self-hosted i.e., its Java code runs on itself without requiring a second virtual machine. Most other virtual machines for the Java platform are written in native code (typically, C or C++). A Java implementation provides ease of portability, and a seamless integration of virtual machine and application resources such as objects, threads, and operating-system interfaces. [Less]

Neko is a high-level dynamically typed programming language which can also be used as an embedded scripting language. It has been designed to provide a common runtime for several different languages. Neko is not only very easy to learn and use, but ... [More] also has the flexibility of being able to extend the language with C libraries. Neko has a compiler and virtual machine. The Virtual Machine is both very lightweight and extremely well optimised so that it can run very quickly. The VM can be easily embedded into any application and your libraries are directly accessable using the C foreign function interface. [Less]

Inferno® is a distributed operating system, originally developed at Bell Labs, but now developed and maintained by Vita Nuova® as Free Software. Applications written in Inferno's concurrent programming language, Limbo, are compiled to its portable ... [More] virtual machine code (Dis), to run anywhere on a network in the portable environment that Inferno provides. Unusually, that environment looks and acts like a complete operating system. The use of a high-level language and virtual machine is sensible but mundane. The interesting thing is the system's representation of services and resources. They are represented in a file-like name hiearchy. Programs access them using only the file operations open, read/write, and close. The 'files' may of course represent stored data, but may also be devices, network and protocol interfaces, dynamic data sources, and services. The approach unifies and provides basic naming, structuring, and access control mechanisms for all system resources. A single file-service protocol (called Styx or 9P2000) makes all those resources available for import or export throughout the network in a uniform way, independent of location. An application simply attaches the resources it needs to its own per-process name hierarchy ('name space'). The system can be used to build portable client and server applications. It makes it straightforward to build lean applications that share all manner of resources over a network, without the cruft of much of the 'Grid' software one sees. Inferno can run 'native' on various ARM, PowerPC, SPARC and x86 platforms but also 'hosted', under an existing operating system (including FreeBSD, Irix, Linux, MacOS X, Plan 9, and Solaris), again on various processor types.

Mac-on-Linux (MOL) provides a virtual machine for running MacOS, MacOSX and Linux (in progress) on your PowerPC machine.

Xerxys is a project to create an operating system that is highly secure and portable through the following aspects: - No application is executed directly on the CPU, but through a Virtual Machine (currently Java compliant) - The system is as ... [More] abstract as possible to ensure the high portability - The system will support data security and high encryption from the beginning Xerxys has an own Java VM implementation, called Xam and an own Java Library called Corepath (which are separate projects).

SMOP is an alternative implementation of a C engine to run Perl 6. It is focused in getting the most pragmatic approach possible, but still focusing in being able to support all Perl 6 features. Its core resembles Perl 5 in some ways, and it differs ... [More] from Parrot in many ways, including the fact that SMOP is not a Virtual Machine. SMOP is simply a runtime engine that happens to have a interpreter run loop. [Less]

Slate is a prototype-based object-oriented programming language based on Self, CLOS, and Smalltalk-80.

SableVM is a robust, extremely portable, efficient, and specifications-compliant Java virtual machine that aims to be easy to maintain and to extend.

TurboVM is a small and simple virtual machine, intended as a compilation target for programming languages. TurboVM uses bytecode with a RISC instruction set designed for easy and fast generation and interpretation, as well as flexibility (i.e. it ... [More] does not impose a certain paradigm like many other VMs). Bytecode can be interpreted or compiled to native code (currently via C). Some speed tests indicate that the bytecode interpreter runs about a factor 15 to 30 slower than native programs, whereas compiling the bytecode yields performance equal to or close to that of equivalent programs written in C.
