Emulating CEDK/KOU-CEDK.COM 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.


Reload DOSee to launch the DOS prompt

Applying changes will reload the page and reboot the emulator





Changes are not applied until the browser tab is reloaded





DOS programs need a keyboard for user input
Some common keys used in DOS programs

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


Emulation too fast?
Set the emulator to use the 386 CPU configuration

Experiencing graphic or animation glitches?
Set the emulator to use VGA only graphics configuration

Need to turn off the audio?
Disable sound card support

Have no audio?
  1. Try Gravis Ultrasound hardware
  2. The song or audio file maybe missing from the program

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, 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 discontinued, 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.
