DOS Zone: Browser-Based Archive of Classic DOS Games Runs on js-dos

DOS Zone is a free, ad-free web portal that streams thousands of classic MS-DOS, early Windows, and IBM PC titles directly in the browser via the js-dos emulator. The catalog spans more than 2,000 MS-DOS entries plus smaller collections for Windows 3.1, 95, and 98, organized by genre across action, RPG, strategy, adventure, simulation, and dozens of other categories, with mobile and offline play supported.

The site is maintained by developer caiiiycuk and survives on voluntary contributions through subscriptions, Buy Me A Coffee, Cloud Tips, and cryptocurrency donations rather than advertising. A multiplayer hub and Russian-language section extend the project beyond solo retro play.

For a technical audience, the interesting layer is js-dos itself: the WebAssembly-based DOSBox port that makes in-browser execution of decades-old binaries practical. DOS Zone functions as both a preservation effort and a live demonstration of how far browser emulation has come for legacy software environments.
