https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+      DOSBox is an emulator that recreates a MS-DOS compatible environment
+      (complete with Sound, Input, Graphics and even basic networking). This
+      environment is complete enough to run many classic MS-DOS games completely
+      unmodified. In order to utilize all of DOSBox's features you need to first
+      understand some basic concepts about the MS-DOS environment.
