DOSBox is capable of emulating many older computer games that are otherwise very difficult if not impossible to play on modern operating systems and hardware. It has very high compatibility, as it can be configured to emulate the environment of many machines, with support for various display modes, including CGA, EGA, Hercules, Tandy, and VGA. With some work, it is even possible to install and load old Windows operating systems, such as Windows 3.11 and Windows 95, thus potentially being able to play games made for those platforms.


Because DOSBox doesn't have a GUI, projects were made to fulfill that role.

D-Fend Reloaded
A great frontend which allows custom per-game configurations to cut back on fiddling with settings just to run specific games well. It also lets you use your own build of DOSBox instead of the one it comes with, so it can be used with forks as well.
DOSBox Game Launcher
Another frontend based on Java that is said to be inspired by the D-Fend's.
IA Launcher
IA Launcher is a graphical games launcher for under 3000 MS-DOS games from old times. It uses the Internet Archive to download games on-the-fly and DOSBox to play them offline.
Originally developed as a DOSBox frontend. It now supports any emulator or Windows game but has retained its excellent DOSBox functionality.


DOSBox has many forks over the years. This section attempts to list the most notable ones. DOSBox's official wiki also has a partial list of DOSBox forks. Even more forks are listed in the DOSBox forks page of DOSBox Staging's GitHub wiki.

DOSBox-X is vastly different from other DOSBox forks in that it aims to be a complete emulation package that covers all pre-2000 DOS and Windows 9x based hardware scenarios. It features more flexibility by way of config options and an accompanying frontend to customize the DOS VM further, and beyond games it also supports standard software for DOS, as well as DOS-based Windows including Windows 3.x and 9x/ME (which it should be able to accelerate in the future). The project also has its own wiki which contains extensive documentation on DOSBox-X, and a summary of notable added features can be seen here. The project is also accessible from the GitHub website.
While DOSBox-X currently supports emulation of IBM PC/XT/AT, Toshiba AX/J3100, IBM PCjr/Tandy, and NEC PC-98 architecture, the maintainer, Jonathan Campbell, does not plan to add any other MS-DOS system. This limitation is mainly done to prevent bloating of the codebase, keeping it at a manageable level for himself while also staying organized. However, the codebase does contain stubbed source files for FM Towns emulation in the event that other programmers want to add that functionality.
DOSBox Staging
DOSBox Staging is a DOSBox fork that focuses on ease of use, modern technology and best practices. Started as a collaborative effort to “revitalize DOSBox's development process”, it attempts to modernize the existing DOSBox codebase and prioritizes the quality of newly written code. The project is also accessible from the GitHub website.
DOSBox ECE is a DOSBox fork that is based on DOSBox SVN commits but with some additional patches such as MT32, FluidSynth and Voodoo/Glide support.
DOSBox Pure
DOSBox Pure is a new DOSBox fork specifically built for RetroArch/Libretro. According to its project description it aims for simplicity and ease of use.[1]


DOSBox Mega Build
Was an enhanced build of DOSBox focused on serial/networking support. Contains the NE2000 patch, parallel port passthrough, virtual printer, OPL passthrough, and others. However, it hasn't been updated in years, and most of what it added was covered by the actively maintained DOSBox-X fork.
Was an enhanced build of DOSBox by ykhwong, with support for Direct3D and HLSL shaders, Glide, Ethernet, virtual printer, and a built-in UI. However, it hasn't been updated in years, and most of what it added was covered by the actively maintained DOSBox-X fork.
Win31DOSBox aims to be an easy method of running Windows 3.x games through a customized version of DOSBox-X or DOSBox SVN. Among its many features, it adds an easy setup program and the ability to print from Windows 3.11. The maintainer of Win31DOSBox has since recommended using WineVDM instead.
To get started, you first need a copy of either Windows 3.11 or WfW (Windows for Workgroups) 3.11. Once you have that, you need to put in either the 6 (Windows 3.11) or 9 (WfW 3.11) floppy images, or the ISO file, or the MSDN self-extracting .exe. After that, running InstallWin31DOSBox.exe which will automatically install Windows 3.x for you. Once it's finished, check that everything works and then install Video for Windows and Quicktime which is located in the Video folder in Program Manager. It is also recommended to install WinG and Win32s as well.
There are multiple ways to get software onto the system. For folders and files, you can drag them into the C-DRIVE folder. If you have a physical CD you can just insert it into your CD drive. If it's a CD image you need to mount it using a software like Virtual CloneDrive. If it's a floppy disk image you need to drag the respective images over the Extract to A-Drive Folder.exe program which will extract them to the A-DRIVE folder.
There was some interest in creating a version of DOSBox that would improve compatibility with Windows 95/98/ME. However, it never passed the theoretical stage.
