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 Open Source.
Notes:
These are unofficial Intel OS X Leopard+ ports of custom patched
versions of the sourcecode.
Added features include Win9X support, support for 3d acceleration
through the use of Glide rendering and more.
