Clock Signal
A latency-hating emulator of: the Acorn Electron, BBC Micro
Clock Signal also known as Clock Signal, is a highly sophisticated multi-system emulator designed with a strong emphasis on minimizing latency and maximizing authenticity in signal reproduction rather than relying on post-processing shortcuts. Its defining philosophy is to make emulation “invisible” to the user, meaning software can be launched directly without requiring manual configuration of machines, disks, or hardware profiles. The emulator supports a wide range of classic systems, including the Apple II, Atari 2600, ZX Spectrum, MSX, and early Macintosh computers, all within a unified architecture. One of its most technically distinctive features is its signal-processing-based rendering pipeline, which simulates original video outputs such as composite signals instead of simply drawing pixels, resulting in highly accurate visual artifacts. CLK also prioritizes extremely low latency by decoupling audio and video pipelines and leveraging modern display capabilities. -

DOSBox ported to Emscripten
An Emscripten port of DOSBox
DOSBox ported to Emscripten is a web-focused port of the classic DOSBox emulator that enables legacy DOS applications and games to run directly inside modern web browsers using WebAssembly and JavaScript. Built with Emscripten, the project compiles the original DOSBox C/C++ codebase into a format that can execute efficiently in a browser environment, bringing near-native performance to web-based emulation. This allows users to launch and interact with DOS programs without installing any software locally, significantly lowering the barrier to accessing retro PC software. The emulator supports a large portion of DOSBox functionality, including CPU emulation, graphics rendering, and input handling, although some edge cases may still present limitations due to browser constraints. One of its key challenges is file persistence, as the default in-browser filesystem is temporary unless explicitly extended. -

RISC-V sandboxing library
The fastest RISC-V sandbox
RISC-V sandboxing library is a high-performance, ultra-low-latency RISC-V userspace emulator library written in modern C++, designed for embedding and sandboxing applications. Unlike full-system emulators, it focuses specifically on executing user-space programs, making it ideal for scenarios such as sandboxed execution, scripting engines, and high-performance server environments. The library is engineered to achieve extremely fast startup and execution times, with the ability to run large numbers of virtual machines concurrently with minimal resource usage. It provides a safe and type-checked interface for system calls and host interactions, reducing the risk of security vulnerabilities during execution. libriscv also supports advanced features such as pause and resume, serialization of execution state, and integration with debugging tools like GDB. Its modular design allows developers to embed the emulator into larger systems and customize behavior for specific use cases. -

Serverless Offline
Emulate AWS λ and API Gateway locally
This Serverless plugin emulates AWS λ and API Gateway on your local machine to speed up your development cycles. To do so, it starts an HTTP server that handles the request's lifecycle like APIG does and invokes your handlers. Options passed on the command line override YAML options. List of available function names and their corresponding serverless.yml function keys are listed after the server starts. This is important if you use a custom naming scheme for your functions as serverless-offline will use your custom name. The left side is the function's key in your serverless.yml and the right side is the function name that is used to call the function externally such as aws-sdk. Once you run a function that boots up the Docker container, it'll look through the layers for that function, download them in order to your layers folder, and save a hash of your layers so it can be re-used in future. -

SimpleNES
An NES emulator in C++
SimpleNES is a lightweight, educational Nintendo Entertainment System emulator written in C++ that focuses on demonstrating the core architecture and behavior of classic console emulation. It replicates the essential components of the NES, including CPU execution, graphics rendering, and audio playback, allowing users to run original .nes ROM files on modern systems. The project supports a subset of cartridge mappers, which means it can successfully run a significant portion of early NES games while still being limited compared to full-featured emulators. Its implementation emphasizes clarity and modularity, making it especially useful for developers or students interested in understanding how emulation works at a low level. The emulator integrates libraries such as SFML for window management and rendering, providing a simple but functional graphical output. -

py-kms
KMS Server Emulator written in Python
py-kms is a Python-based emulator of Microsoft’s Key Management Service (KMS), designed to simulate activation servers for Windows and Microsoft Office volume licensing systems. It is derived from earlier implementations and reverse-engineered protocols, allowing it to respond to activation requests from client machines. The software supports multiple versions of the KMS protocol, enabling compatibility with a wide range of Windows and Office releases. It can be deployed in various environments, including standalone systems, Docker containers, and service managers like systemd, making it flexible for testing and development scenarios. The emulator includes features such as logging, configurable network parameters, and persistent storage using SQLite. While it is often used for testing activation workflows, it also serves as a practical example of protocol emulation and reverse engineering in software systems. -

Boxedwine
Emulator that can run 32-bit Windows programs/games
Boxedwine is a cross-platform emulator that enables users to run Windows applications by combining a Wine runtime with a custom emulated Linux kernel and CPU environment. Instead of relying on a native Linux system, it creates a fully self-contained execution environment that allows Windows binaries to run on platforms such as macOS, Linux, Windows, and even web browsers via WebAssembly. The project is written primarily in C++ and leverages SDL for graphics and input handling, providing a flexible runtime capable of supporting a wide range of applications. It supports both 16-bit and 32-bit Windows programs, along with graphics APIs such as OpenGL, Direct3D, and Vulkan for rendering. One of its key innovations is portability, as it can run in environments that traditionally cannot support Wine, including browser-based deployments. While performance and compatibility vary depending on the application, it continues to evolve with improvements in memory usage and execution speed. -

Sogen
Windows User Space Emulator
Sogen is a high-performance Windows user-space emulator designed to operate at the syscall level, offering deep control over process execution and behavior. Unlike traditional emulators that reimplement full operating system APIs, Sogen works closer to the kernel boundary by intercepting and emulating system calls, allowing it to leverage native system libraries while maintaining granular control. This approach makes it particularly valuable for advanced use cases such as malware analysis, reverse engineering, and DRM research, where precise observation and manipulation of execution flow are critical. The emulator supports multiple backends, including Unicorn Engine and Hyper-V, enabling flexible deployment depending on performance or accuracy requirements. It also includes robust support for loading Portable Executable (PE) files, including proper handling of relocations, thread-local storage, and memory mapping. -
