A custom virtual machine for the Stars! 4X game

Stars! is a 1995 4X game (explore, expand, exploit, exterminate) for 16-bit Windows 3.1 that I first played ~28 years ago. While Windows is famously backwards compatible, it’s notoriously difficult to play Stars! today. Windows x64 cannot run 16-bit applications, and playing requires either retro hardware or emulation (otvdm, DOSBox), sometimes paired with Wine. My new, exciting solution, Stars!VM, or Stars! Virtual Machine, embeds a custom 80286 emulator and a Win16 to Win32 bridge. As native Win32, the game looks and feels exactly as it did originally, except sporting a modern file chooser and 4k scaling. It’s indistinguishable from a genuine 32-bit or 64-bit port of the game, especially with the original 16-bit game embedded inside the VM executable. The signed releases on GitHub embed a compressed copy of the original 16-bit game, so that single EXE is ready to play out-of-the-box with no further setup or downloads. I’m distributing 32-bit builds (but requires SSE2) because…
