Vision: Continued DOS Development Efforts

Despite the rumors of its demise DOS is actually never dead. There are many continued development efforts in the DOS world including now. For example, even though Microsoft had ended support for its MS-DOS systems about two decades ago, there is the open source FreeDOS project which is designed to be a free DOS system compatible with MS-DOS and is under active developments as of this day. There are many other DOS software being actively maintained and updated as well. Just to name a few examples:

  • Want to play music? MPXPLAY is a powerful audio player for DOS that supports many multimedia formats such as MP3, AAC, OGG, and FLAC.
  • Want to manage files? Doszip Commander is a long filename (LFN)-aware file manager (Norton Commander clone) with built-in Zip and UnZip support.
  • Want to program in Pascal? Free Pascal is a versatile and open-source Pascal compiler that can target many processor architectures. DOS version is available.
  • Want to run network applications? mTCP is a set of TCP/IP applications for DOS and include applications like DHCP, FTP, FTPSRV, HTGET, and other networking tools.
  • Want to run Windows console applications in DOS? HX DOS Extender is a free DOS extender with built-in Win32 PE file format support and development tools.
DOSBox-X is designed to be a general-purpose DOS emulator that is both complete and accurate, including emulations of all PC systems used by MS-DOS (or compatible) between 1980 and 2000 (e.g. 8086, 286, 386, 486, Pentium, Pentium Pro, etc). Apart from emulating existing DOS games and applications (and DOS-based Windows like Win3.x/9x), we also hope that it can aid in new DOS developments (also called retro-developments or futuristic developments). We would like to implement DOS emulation that is accurate enough to help make new DOS developments possible with confidence the program(s) will run properly on actual DOS machines.

It is very encouraging to see developers to write new DOS games or applications, even if they are 32-bit C++17 code compiled with MinGW and to run with the help of HX DOS Extender or even JavaScript code interpreted by a JavaScript programming environment for DOS such as DOjS. DOSBox-X is very flexible and provides many configuration parameters in its full configuration file (take a look at dosbox-x.reference.full.conf) so that you can test your program against odd scenarios or problems with systems that may cause some programs to not function properly.

Not only we have DOSBox-X for emulating DOS, we also have DOSLIB and DOSLIB2 which provide numerous DOS programming example libraries (and sample code for Windows 3.x/9x) which are also used to test DOSBox-X and real DOS systems, as well as Hackipedia which is a comprehensive online documentation collection for DOS-related programming. Be sure to check them out too!
