A complete open source MS-DOS emulator for a multitude of operating systems. DOSBox not only emulates DOS, but also a VGA graphics card and Sound Blaster audio card. It currently does not support any protected mode software, but runs most games and applications up to around 1992 very well and with reasonable performance on lower-end PCs. It can even run VGA graphics inside a window on the desktop.
