Win3mu

Win3mu is a Windows 3.0 emulator. It includes an 8086 CPU emulation that loads 16-bit Windows executables and maps API calls onto the modern 32 or 64-bit Windows API.

Win3mu was started as a hobby project - mainly as a curiousity to see if it could be done. Unfortunately, once that challenge was met my interest in the project waned and due to other commitments (ie: paying projects) and other interests I no longer have much time to spend on it. So I'm handing it over to the open source community in the hope someone might take an interest in it and continue to develop it.

How to Build Win3mu

It requires Visual Studio 2017 and .NET 4.6.1. To build it, clone the repository, init the submodules, open the solution file and build the win3mu project.

• To run a 16-bit program, pass the path to the 16-bit executable program as a commend line argument to win3mu.exe.
• If the 16-bit program uses any APIs that haven't been implemented you'll get an exception. Implement the missing API, rinse and repeat.

Technical Details

During development of this project I wrote a series of articles that explains how it works. You can read these here.
