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

This is the only way to run Scorched Earth under 32-bit Windows Vista and 7. Apparently after Windows XP Microsoft removed all support for 16-bit DOS apps.

If you ever used DOS back in the old days it's impossible not to love DOSBox :)

Excellent work and a must have for legacy DOS based games and applications. This is not the same as VMWare or similar virtual machines - this is a self-contained emulator. VMWare, Parallels etc require you to install DOS, all sound, CD-ROM, VESA VBE drivers yourself. This is a stand-alone utility that has a built-in DOS command interpreter, ADLIB/SB/SBPRO/SB16/GUS et al sound drivers and VESA video. It does not require virtual hard drives you simply mount a directory of your choice and assign a drive letter.

For certain games this works better than virtualization. I like the fact that you can adjust the CPU clock cycles for older games that run too fast on today's machines. (Wing Commander is a perfect example).

If you were considering setting up a VMWare DOS environment but don't want to go through all the fun of tweaking CONFIG.SYS and AUTOEXEC.BAT to get maximum base memory try this instead. Highly recommended. Also check the forums, lots of helpful advice on getting your old apps to run.

wetink Just because you are an idiot does not mean you have to give a great program a lower rating.

Maybe useful ...
But why not taking DRDOS/NovellDOS and have a multiboot system?!
... ran fine with Win98, but don't know how it works on a NTFS-File-System.
