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

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 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.

         unprotect program created by Sam Brown of the Byte Bandits
      realization, document, and redistribution by Bushido the Warrior

     I was looking through a special bulletin board system,  when I  noticed
     a MindScape program on the directory list.  Curious, I downloaded it. I
     realized that this program was "cracked" by Sam Brown,  an acquaintance
     of mine. The protection scheme he went crazy over to break finally came
     out to be small COM file, of about only 1k!  I  examined  this program,
     and thought... "Could this little program work on other MindScape games
     I've BOUGHT?"  So, I began my 10-minute investigation.

     This program is a small memory-resident program that allows most of the
     MindScape software to be played without the "key disk"  or  "installed"
     fixed drives.  It makes the program  believe it had picked up the  weak
     bits on the disk (the protection scheme), so you can play.

     First, copy the files of the game to a blank disk, hard drive,  virtual
     disk, or what have you.
     Next, to activate it, type "WEAKBIT" at the DOS prompt, and hit  ENTER,
     obviously.  Run  this  program  ONLY  once.  I  haven't seen what would
     happen if you ran it more than once, but I wouldn't like to know, and I
     hope that feeling would be the same with you. I suppose it modifies the
     INTerrupt 13, a disk interrupt.  From there,  load up the game.  Voila.
     It should load. If not, reboot and verify your steps. If problems still
     persist, either:  MindScape has changed its software protection scheme,
     you are running an old version of the MindScape program, which  has  an
     older protection scheme, or it isn't a MindScape program!
     I suggest a reboot after you have finished playing.  Returning  to  DOS
     on  my  computer  usually ends up with a "system hang."  It might be my
     system or its loaded TSRs, but you're never too sure.

     This program has been tested on the following games:

       Bop'n Wrestle                  Into the Eagle's Nest
       Infiltrator                    Gauntlet
       Infiltrator II                 SuperStar Indoor Sports

 The program WEAKBIT.COM should be 1536 bytes long.  Just to  be on the safe
 side, you know many demented programmers change software around to  be very
 hazardous to one's system.  Check the program for disk writes,  which there
 should  be  NONE,  or  write-protect  your drives with Lightning, or the PC
 Magazine's HARDLOCK.COM (is that it?). But, I can assure you from here, the
 program is as good as gold.
