The Problem

Classic DOS software and demos represent an important part of computing history, but experiencing them requires technical knowledge to set up emulators, source disk images, and configure audio/video settings. This creates a barrier that prevents casual users from exploring vintage computing culture.

The Solution

Built a WebAssembly-powered platform that runs DOS software directly in modern browsers with zero installation. Users simply click and play - the emulator, software, and configuration are all handled automatically, making computing history accessible to everyone.

The Results

  • One-click access to classic DOS software and demos
  • No installation, plugins, or configuration required
  • Touch controls enable mobile device support
  • Curated library of historically significant software

Key Features

  • Instant Access: One-click access to DOS software
  • Browser-Based: Runs entirely in the browser via WebAssembly
  • Curated Library: Classic demos, games, and applications
  • Mobile Friendly: Touch controls for mobile devices

Technical Implementation

DosKit leverages js-dos, a WebAssembly port of DOSBox, to run x86 DOS binaries directly in the browser:

const dos = await Dos(canvas, {
  wdosboxUrl: '/wdosbox.js',
  autoStart: true
});

await dos.fs.extract('/software.zip');
await dos.main(['-c', 'SOFTWARE.EXE']);

The emulator handles CPU emulation, memory management, and audio/video output, providing an authentic DOS experience without any native installation.
