winevdm: Running 16-bit Windows on 64-bit Windows
Summary
This article analyzes winevdm, a project that runs 16-bit Windows apps (Windows 1.x to 3.x) on 64-bit Windows via a Wine-based emulator. It covers usage, installation, and building from source (Visual Studio or cmake), and outlines key architectural components such as DOS emulation and 16-bit to 32-bit HANDLE conversion.
