Windows User Space Emulator
A high-performance Windows process emulator that operates at the syscall level, providing full control over process execution through comprehensive hooking capabilities.
Built in C++ and powered by the Unicorn Engine.
## Key Features
* __Syscall-Level Emulation__: Instead of reimplementing Windows APIs, the emulator operates at the syscall level, allowing it to leverage existing system DLLs
* __Advanced Memory Management__: Supports Windows-specific memory types including reserved, committed, built on top of Unicorn's memory management
* __Complete PE Loading__: Handles executable and DLL loading with proper memory mapping, relocations, and TLS
* __Exception Handling__: Implements Windows structured exception handling (SEH) with proper exception dispatcher and unwinding support
* __Threading Support__: Provides a scheduled (round-robin) threading model
* __State Management__: Supports both full state serialization and fast in-memory snapshots
* __Debugging Interface__: Implements GDB serial protocol for integration with common debugging tools (IDA Pro, GDB, LLDB, VS Code, ...)
Perfect for security research, malware analysis, and DRM research where fine-grained control over process execution is required.
## Code Disclaimer
The project is still in a very early, prototypy state. The code still needs a lot of cleanup and many features and syscalls need to be implemented. However, constant progress is being made :)
