DOSBox SVN r3867 is released. DOSBox emulates an Intel x86 PC, complete with sound, graphics, mouse, joystick, modem, etc., necessary for running many old MS-DOS games that simply cannot be run on modern PCs and operating systems, such as Microsoft Windows XP, Windows Vista, Linux and FreeBSD. However, it is not restricted to running only games. In theory, any MS-DOS or PC-DOS (referred to commonly as "DOS") application should run in DOSBox, but the emphasis has been on getting DOS games to run smoothly, which means that communication, networking and printer support are still in early development.

DOSBox also comes with its own DOS-like command prompt. It is still quite rudimentary and lacks many of the features found in MS-DOS, but it is sufficient for installing and running most DOS games.
