DOS emulator.

Overview

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.

What's new in DOSBox

Version 0.74-3:
  • Implement basic file access control for files available from within the emulation, so that programs running inside DOSBox can't access /proc (e.g. /proc/self/mem). (CVE-2019-12594)
  • Unify unmounting code and add some protections against out of bound access when DOS_DRIVES is not 26.
  • Use correct type for return value of strlen.
  • Change scan3x to a bit brighter.
  • Fix unitialized access to some isoDrive fields and improve stability when switching CD images.
  • Small fix to hq3x.
  • Fix 256 colour mode encoding in zmbv.dll.
  • Some small aliassing fix.
  • Change SET to check the size of the MCB when adding variables. Fixes hangs with Norton Commander.
  • Check buffer length before doing tab completion.
  • Correct buffer overflow with very long lines in bat files. (CVE-2019-7165)
  • Correct the boundary check for the internal programs array.
  • Increase stability in max cycles mode by increasing the lower bound.
  • Fix command prompt in windows 3.11 with dynrec core.
  • Fix Win64 dynrec core.
  • Always clear buffers before drawing in OpenGL mode. Fixes artifacts with drivers that have more than 2 buffers and overlays.
  • Fix red border that appeared when scaling the image in OpenGL mode with Nvidia on Linux and Mac.
  • Change default output to opengl on Mac, as surface is very slow there in 64 bit.
  • Add workaround for the mouse unlocking problem with X.org 1.20.1.
  • Fix table access when USE_FULL_TLB is undefined (non-default configuration).
  • Several fixes to prevent compilation errors.
  • Update Visual studio file to fix missing files from 0.74-2.

what a GREAT little app! it appears to run games with near perfect sound and video emulation MUCH better than virtual PC. somethings are a bit buggy, and doesnt run completely smoothly on some games, but its definately something to keep your eye on. good job!

It seems to totally ignore any changes I make to the default DOSBox.Prefs file and doesn't recognise the 'conf' command when I try to remind the app where the config file is located. After setting the frame skipping to 1 and increasing the CPU cycles I managed to run Command & Conquer at a reasonable speed on a Mac Mini 1.4ghz with 512mb RAM.

Amazingly promising. Runs Ultima Underworld without a hitch. Only problems with hooking it up with more conventional memory, so can't play the sequel

Works fine except for the characters. This just won't be the same as the keyboard. Example, when I type ":", it shows a ">". How can I solve that?

It is fantastic and yet terribly slow. How do I turn off sound? I've got a powerbook G4 and the sound here is worse than my Apple IIc. I wish more info came with this program... I hope there'll be an update... I hope there'll be at least one menu option in the updated version... Would be nice also, if you could click out of this window without having to cmd-tab all the time...(small thing)

I have radnor and the sdl library installed. I have never really used dos, so I cannot figure out how to mount a cdrom rom. Any help? The dosbox website isnt very helpful.

OK, I didn't realize at first that I needed Radnor to run on top of this: with it, I'm able to run my favorite DOS games after all...and they run on my 1GHz Emac with 750 megs of RAM with no noticeable slowdown in speed (they have motion and sound, but aren't FPS games, so speed isn't as critical). One of these games isn't the most stable going, but it ran with no glitches. I'm really pleased!
