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, Mac OS 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.

• OSes might benefit as well.
• Update 64bit recompiler to work on OSX and Linux.
• Several improvements to make the recompilers work with newer compilers and
• add some workarounds about clang confusing itself.
• Fix several variables being the wrong size in the recompiler.
• Support absolute 64 bit addressing. (DRC:64 bit error messages)
• Zero extend data in dynrec core for LLVM compilation/
• Reduce overhead of the Mac version with a lot. Results in a speed increase.
• Replace NV_PixelDataRange with the more common ARB_PixelBufferObject
• extension. Should help with output=opengl.
• Reuse graphics window if possible instead of always creating a new one!
• Add patches to work better when called by WINE:
• support WINE style namemangling.
• allow Z: to be moved to a different drive.
• Try to fix stuttering audio with opengl output on Linux. (or at least improve it. Linux users might need to increase the prebuffer option a bit)
• Fix automake and autoconf problems.
• Fix problems related to packed struct layouts.
• Fix compilation on gcc 4.4 and gcc 4.6.1.
• Fix compilation with -DPIC.
• Hopefully fix crash on shutdown, when unknown condition is encountered.
• Fix -lto with gcc.

• Fix mapper crash on startup and when changing the mapper key.
• Fix compilation in VS2015.
• Fix compilation on mingw64.
• Fix compilation on Frisbee and newer clang.
• Fix compilation machines that have X11 libraries installed, but use a SDL
• without X11.
• Fix a few problems relating to video capturing:
• Writing out the index too often. (slowdown with longer captures)
• Not being aware of when only the refresh rate changed.
• Fix call order when bitshifting the return order (VS C /O2 builds).
• Fix sign-extension error in S3 draw funcion, i.e. win3.1 analog clock.
• Fix expanddot not caring about the size of the inputbuffer.
• Some fixes for the debugger related to starting a program through debug.com.
• Bring OS/2 port code up to date.
• Reduce the amount of warning when compiling with quite a bit.
• Allow 15/26/32 bits input to the opengl output.
• Add cmd-q as exit key for macs.
• Fix icon and titlebar on very old setups.
• Fix off by one display size calculation errors with very large displays.
• Fix out of bounds access the unused byte in the 32 bit colour value of the
• hardware mouse cursor pixel was affected.
• Fix depreciated warnings on Mac, allow soundfont loading for coreaudio.
• Keep repeating a pressed key if another key was unpressed.
• Fix crash on OS X related to putting junk in the titlebar.
• Extend fullresolution=0x0 to work on Linux and Mac.
• Change gameblaster and tandy sound core to latest mame version.
• Improve numlock and capslock support on Linux and Macs.
