js-dos is a TypeScript library and API for running DOS and Windows 9x programs in the browser or Node.js, acting as a frontend for DOSBox/DOSBox-X emulators compiled to WebAssembly. It offers advanced features like 3Dfx-accelerated rendering, IPX networking over WebRTC, multiplayer, save/load persistence via OPFS, and streaming of large disk images.

Use cases

• run dos games in the browser
• embed a dos emulator in my web app
• play windows 95/98 games in browser
• add multiplayer to browser dos games
• stream large dos disk images without a backend
• save and load dos game state in the browser
• run dos programs in node.js

When to choose

• you want to run DOS or Win9x software in a browser with minimal setup
• you need advanced features like 3Dfx rendering, IPX networking, or multiplayer
• you want to serve huge DOS games via backendless disk streaming
• you need both browser and Node.js execution

When to avoid

• you need to emulate non-DOS platforms like consoles or arcade systems
• you want a general-purpose emulator frontend for desktop use rather than web embedding
• you require a permissively licensed dependency and cannot accept the project's missing license
• you need production mobile support on v8, which is still work-in-progress
