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.

dEPROTECT for Ultima V There is a Ultima V deprotect available on many many boards. It may work for some but unfortunately not for my version. Or maybe I'm just thickheaded and couldn't follow the instructions. Anyway this patch works (on my copy!). To see if your copy is the same as mine get into debug and look at location 8AB0 -- it should start off DB 96 DB 8E E1 4C 98 74....... - if not you have a different version yet! -- You might try a search function to find that string and alter the locations in the ULTIMA.DAT file to correspond to your version. Those familiar with debug should have no problem doing this - others probably shouldn't attempt it in the first place. First make a copy of your Ultima V Program disk using diskcopy -- then put away your original! Take a formatted blank disk and place it in drive B. Copy Dos Debug and both Ultima.DAT and ULTIMAGO.BAT from this zip file to the disk in Drive B. Then place your COPY of Ultima V program disk in drive A (make that your root directory) and at the "A:" prompt, type "B:ultimago (return)" (Don't type the quotation marks of course. Your disk is now unprotected and the files may be copied to a hard disk, ram disk or standard DOS disk using XCOPY. P.S. For those of you who care about these things, the protection scheme involves a non-standard formatting of track 6, side 0. It has 10 sectors instead of the normal 1-9 and they are numbered 01-02-BB-03-BC-04-BD-05-BE-AA. Normal size and normal CRC checksums. -- The Reno Cracker
