Emulating HAL2.BAT in DOSee.

Use these tabs to make adjustments to the emulation

If the emulation is taking too long to load, you can turn it off.

Applying changes will reload the page and reboot the emulator





Changes will not be applied until this browser tab has been refreshed





DOS programs need a keyboard for user input

ENTER to select or continue
ESC to navigate back or exit
are often used to navigate menus


Emulation too slow?
Set the emulator to use maximum CPU speed
Want to hack around in the DOS prompt?
  1. Mount the DOS tools drive with automatic run program turned off
  2. Then dir u:\ to list the utilities, some included programs 4dos cp acidview pictview
  3. Use mount to list the emulated drives
  4. Learn the DOSBox commands

DOSee pronounced dos/see, is our emulator used to run MS-DOS based software in your web browser.

MS-DOS (Microsoft DOS) was the primary operating system used by PCs during the 1980s to the early 1990s and is the precursor to Microsoft Windows.


DOSee is a slimmed down, partly modified port of The Emularity.

The Emularity is a multi-platform JavaScript emulator that supports the running of software for legacy computer platforms in a web browser. It is the same platform that's running emulation on the Internet Archive.

EM-DOSBox is a high-performance JavaScript port of DOSBox that is applied by The Emularity for its emulation of the MS-DOS platform.

DOSee uses BrowserFS ZipFS and ZipFS Extras to simulate zip file archives as hard disks within EM-DOSBox.

DOSBox is the most popular MS-DOS emulator in use today and is frequently used by commercial game publishers to run games from their back-catalogues on modern computers.


DOSee, built on The Emularity, EM-DOSBox and DOSBox. Capture screenshot and save function built on canvas-toBlob.js.
