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.

*************************************************************************** Almost Unprotecting Leisure Suit Larry II *************************************************************************** Leisure Suit Larry II is arguably Sierra Online's best interactive graphic adventure game. It is protected by the singularly obnoxious "answer a ques- tion from the manual" trick. When you start the game, you must fill in the last four digits of a girl's telephone number. The pictures of these girls appear throughout the manual. This unprotect requires changing four bytes in the file SIERRA.EXE, found on diskette #1. However, this unprotect is not as perfect as I'd like it to be. I set out to make the unprotect completely bypass the "Type in Phone Number" screen. Well, as I traced the code I found that to do so would be considerably difficult and would require the modification of extensive amounts of code. Instead, the modification we will make will cause the same girl's picture to appear every time you start the program. This means that you will be able to enter the same phone number every time you start the program. The phone number will be 7448. Nothing herein is to be construed as subversion of or violation of the rights of the authors of these "copy protected" games and other items. These authors certainly maintain the right to protect their works in any manner which they deem fit. However, their decision to inflict difficulties in the operation of their products by legitimate users should be protested vigorously. This docu- ment is a living example of my heartfelt belief in this matter. This unprotect requires a file utility such as PC-TOOLS DELUXE or NORTON's. Search for the following four-byte hex string: 8B C2 EB F4 And replace it with this four-byte hex string: B8 02 00 90 Write the changes and your done. The phone number will always be 7448! For people familiar with debug, the location of these bytes is 8BBD through 8BC0.
