DOSBox has already been ported to many different platforms, such as Windows, BeOS, Linux and macOS.
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.
What's New:
- Fixed that a very long line inside a bat file would overflow the parsing buffer. (CVE-2019-7165 by Alexandre Bartel)
- Added a basic permission system so that a program running inside DOSBox can't access the contents of /proc (e.g. /proc/self/mem) when / or /proc were (to be) mounted. (CVE-2019-12594 by Alexandre Bartel)
- Several other fixes for out of bounds access and buffer overflows.
- Some fixes to the OpenGL rendering.
