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.
