• Step 1: download.

  Official NetHack 3.6.7 binaries for Intel 386 compatible machines running DOS or Windows 3.1. In general we recommend the Windows version if your machine can run it.
  Note that it is no longer necessary to use this binary to get a graphical interface. The Windows version now supports that functionality.

  This contains the protected-mode version of NetHack built with djgpp V2. It requires at least 3MB extended memory. A '386 or greater processor is needed. (about 1.1M)

  It requires DPMI to run. If you want to run it on plain DOS you can get CWSDPMI , unpack it, and put the CWSDPMI executable in your NetHack directory.
