Editing DOSBox (section)

==Development==
Before [[Windows XP]], consumer-oriented versions of Windows were based on [[MS-DOS]]. [[Windows 3.0]] and its updates were [[operating environment]]s that ran on top of MS-DOS, and the [[Windows 9x|Windows&nbsp;9x]] series consisted of operating systems that were still based on MS-DOS.{{Sfn|Norton|2004|p=286}} These versions of Windows could run DOS applications. Conversely, the [[Windows NT]] operating systems were not based on DOS. A member of the series, Windows XP, debuted on October 25, 2001, and became the first consumer-oriented version of Windows to not use DOS. Although Windows XP [[NTVDM|could emulate DOS]], it could not run many of its applications as they ran only in [[real mode]] to directly access the computer's hardware, and Windows XP's [[Virtual DOS machine#Windows NTVDM|protected mode]] prevented such direct access for security reasons.<ref name="56Fa6">{{cite web|url=https://www.howtogeek.com/188980/pcs-before-windows-what-using-ms-dos-was-actually-like/|title=PCs Before Windows: What Using MS-DOS Was Actually Like|last=Hoffman|first=Chris|work=How-To Geek|date=May 11, 2014|access-date=November 2, 2020}}</ref><ref name="D0qCI">{{cite book|chapter-url=https://books.google.com/books?id=ZQCWAAAAQBAJ&pg=PT49|chapter=Introduction to Windows 7 – The Road to Windows 7|title=MCTS 70-680 Exam Cram: Microsoft Windows 7, Configuring|last=Regan|first=Patrick|publisher=[[Pearson Education]]|date=March 8, 2011|access-date=November 2, 2020|isbn=9780132603201}}</ref> MS-DOS continued to receive support until the end of 2001,<ref name=Windows-7>{{cite book|url=https://books.google.com/books?id=S6ffBQAAQBAJ&pg=PA116|title=Microsoft Windows 7 in Depth|last1=Cowart|first1=Robert|last2=Knittel|first2=Brian|publisher=[[Que Publishing]]|date=December 2010|access-date=December 15, 2020|page=116|edition=4th|isbn=978-0-7897-4199-8}}</ref> and all support for any DOS-based Windows operating system ended on July 11, 2006.<ref name=ITPro-2006>{{cite web|url=https://www.itprotoday.com/windows-78/finally-windows-98me-move-towards-retirement|title=Finally, Windows 98/Me Move Towards Retirement|last=Thurrott|first=Paul|work=ITPro Today|publisher=[[Informa]]|date=April 12, 2006|access-date=December 15, 2020}}</ref>

The development of DOSBox began around the launch of [[Windows 2000]]—a Windows NT system{{Sfn|Norton|2004|p=288}}—when its creators,{{Sfn|Loguidice & Barton|2014|p=103}} Dutch programmers Peter Veenstra and Sjoerd van der Berg, discovered that the operating system had dropped much of its support for DOS software. The two knew of solutions at the time, but they could not run the applications in windowed mode or scale the graphics. The project was first uploaded to [[SourceForge]] and released for beta testing on July 22, 2002.<ref name="Nizlk">{{cite web|url=https://sourceforge.net/blog/potm-200905/|title=Project of the Month, May 2009|website=[[SourceForge]]|access-date=2013-01-17|archive-url=https://web.archive.org/web/20091117075950/http://sourceforge.net/community/potm-200905/|archive-date=2009-11-17|url-status=dead}}</ref>
