Play classic games
Play DOS games on FreeDOS! We include lots of fun games in the distribution. Or play your favorite classic games, like Wolfenstein 3D, Doom, Commander Keen, Jill of the Jungle, Duke Nukem, and many others!
Welcome to FreeDOS
FreeDOS is an open source DOS-compatible operating system that you can use to play classic DOS games, run legacy business software, or write new DOS programs. Any program that works on MS-DOS should also run on FreeDOS.
Run applications
Run your favorite DOS programs with FreeDOS. Just install your DOS application under FreeDOS like you would any other DOS application and you'll be good to go.
For developers
We include lots of open source compilers, assemblers, debuggers, and editors so you can create your own DOS programs. We also share our source code under an open source license, so you can modify FreeDOS itself.

Lynx 2.9.3 (needs DOS exe)
Lynx is a web browser that works in text mode. Lynx version 2.9.3 was released on May 31, and includes several key fixes and updates; see the list of changes for details. However, this version does not have a DOS exe (although the sources contain a DOS makefile). If you'd like to contribute, consider compiling (and sharing) a DOS exe for others to use. You can get the new release from the Lynx website.
X-VESA video testing program
X-VESA is a DOS diagnostic program for in-depth analysis and verification of VESA interfaces on real hardware, written entirely in x86 assembly language. Thanks to Marco for sharing this program. See X-VESA on GitHub for more information, including a full list of features and source code. X-VESA is available under the GNU GPL v3.
VSBHDA v1.9
If you want to play DOS games on modern hardware, another option to emulate SoundBlaster is VSBHDA, the Virtual Sound Blaster for HDA sound cards. Thanks to Japheth for releasing an updated VSBHDA with several fixes, including: fixed regression in v1.8: sound may have been distorted in Open Cubic Player, and contains preliminary hdpmi v3.24. Download the latest release from VSBHDA on GitHub or more directly from version 1.9.
SBEMU updates
Classic DOS games talk directly to sound hardware, such as a SoundBlaster. Modern systems don't have SoundBlaster cards, but you can use SBEMU to emulate one on DOS, so your DOS games will work on new hardware. DOS developer Crazii is doing some new work in VDPMI with dynamic switching of PVI that helps against some stuttering. VDPMI and SBEMU both have several fixes. Check out the latest updated via the Vogons message board for more news.
