id Software uses DOSBox emulation for our vintage game titles on Steam.

DOSBox has allowed us to bring classic DOS gaming to modern Windows XP/Vista operating systems, exposing an entire new generation of gamers to the classic back library of id Software.

About DOSBox
DOSBox is a DOS-emulator that uses the SDL-library which makes DOSBox very easy to port to different platforms. DOSBox has already been ported to many different platforms, such as Windows, BeOS, Linux, MacOS X...

DOSBox also emulates CPU:286/386 realmode/protected mode, Directory FileSystem / XMS / EMS, Tandy / Hercules / CGA / EGA / VGA / VESA graphics, a SoundBlaster/Gravis Ultra Sound card for excellent sound compatibility with older games...

You can "re-live" the good old days with the help of DOSBox, it can run plenty of the old classics that don't run on your new computer!

DOSBox is totally free of charge and OpenSource.
