DOSBox

DOSBox is a DOS-emulator using SDL for easy portability to different platforms. DOSBox has already been ported to several different platforms, such as Windows, BeOS, Linux, Mac OS X...

DOSBox emulates a 286/386 realmode CPU, Directory FileSystem/XMS/EMS, a SoundBlaster 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!

This version of DOSBox is sandboxed. You have to copy your DOS files to your Documents directory and mount them using a mount command in DOSBox.
