Open Source Emulators

Locale Emulator is a tool similar to AppLocale and NTLEA, providing a simulation function that can make an application recognize your OS as in a language other than the real one. It is quite useful when you are trying to play country-specific games. Locale Emulator is compatible with the following systems, both 32 and 64-bit, Windows 7 with Service Pack 1, Windows 8.1, and Windows 10. Locale Emulator supports 32-bit executables running on both 32-bit or 64-bit systems. For example, if you are using 64-bit WinRAR, you will not see the context menu on a RAR file unless you swapped 64-bit WinRAR with the 32-bit version. Clone the repo using Git, install Microsoft Visual Studio 2015 / 2017, open LocaleEmulator.sln, perform build action, clone and build the core libraries, and copy LoaderDll.dll and LocaleEmulator.dll from Locale-Emulator-Core to Locale-Emulator build folder.

Virtual T is a TRS-80 Model 100/102/200 emulator that runs on Windows, Linux, and Macintosh. The goal of Virtual T is to provide 100% hardware emulation so any existing programs will run. It also adds powerful development and debugging tools.

NET-Simulator was created to help lecturers and students in the study of computer networks. Students can build virtural networks in the virtual environment provided by NET-Simulator. These devices are controlled by means of command line interface.

HALT is a developer friendly programming and simulation environment for the Motorola 680x0 family of processors. Targeted at academia, it is centered around ease of use and utility.

Tiny8051 is small 8051 microcontroller simulator written in C#. Project was created for educational purposes, to show how µP works by using clean visual interface and debugging. Note: communication over serial port was not implemented, because there was no demand for it.

eMKatic — это кроссплатформенный эмулятор современных ЭКВМ серии «Электроника» производства НПП «СЕМИКО» (г. Новосибирск), являющихся развитием советских программируемых микрокалькуляторов с обратной польской нотацией Б3-34, МК-52, МК-61.

For new versions, check https://github.com/Darkkey/javaNetSim javaNetSim (Java Network Simulator) - it's a fork of a project jFirewallSim. The main goal of javaNetSim is creating a software to simulate various TCP/IP networks based on Ethernet, WiFi, PPP, etc...

MIPS R3000-based virtual machine with support for serial console and GNU cross-compiler tools.

Catakig: an emulator of the venerable Apple II personal computer.

This project aims to implement an LC2/LC3 assembler and simulator for the Linux and Windows platforms.

Blubber system is an Eclipse RCP application for distributed systems modeling. Designed for university researches and inlcudes: task graph editor; graph transformation tools; graph modelling on distributed system; real-time modelling on GerdaFramework.

cp1-sim enables the user to simulate the famous KOSMOS CP1 educational computer from the 1980's on any PC or Mac. Give us some feedback! :)

CYGNIX means "CYGnus pseudo-uNIX". It is a pseudo-UNIX environment based on CygWin. It's tiny and not meant to be a full featured CygWin developing environment. CygNix is ideal for Unix users who sometimes have to do some routine works on Windows.

The Emulation Framework offers a convenient way to render digital files in their native computer environment. The EF is software developed in Java by the international KEEP project, co-funded by the European Unions 7th Framework Programme.

JSim8086 is platform-independent Assembly Language Simulator of the Intel 8086 CPU. It was designed to be a learning tool (CAL) for first year Computing students who are learning Computer Systems Organisation and Assembly Programming.

A kit for simulating the MIC-1 / IJVM computer architecture.

Mahatma68k is a free/Open Source emulator library for the legendary Motorola 68000 CPU written for the Java virtual machine.

The Network Simulation Environment (NOSE) has the capability to virtually create complex networks including different types of operation systems very cost-efficient on a single computer.

OSProg (Open Source PRogrammer) is a device programmer project. The target is to provide with wide range supported devices (PROM, EPROM, EEPROM, PIC, MCU, etc) at low price, simple and flexible hardware design.

An emulator for an educational CPU (P3) used in a Computer Architecture (AC) course in IST (a University in Lisbon, Portugal). The CPU is only theoritical and has a software simulator already implemented. Purpose: final AC project testing and evaluation.

Creating own PASCAL language interpreter.

A newer version is available for mac at https://cowpod.net/projects/raspiemu, which supports the Raspberry Pi 2, multiple instances, as well as CLI and GUI management. An automated Raspberry Pi emulator for Mac OS X, Ubuntu, as a well as a few other Linux distributions. As of 2021, the disk images are no longer available. You will need to manually download and patch said images.
