    (description
     "The DOSBox Staging project attempts to modernize DOSBox.

DOSBox emulates an Intel x86 personal computer running an IBM PC compatible disk
operating system (@dfn{DOS}) in both real and protected modes.  It was primarily
designed to run old DOS games, but aims to be fully compatible with all DOS
programs and replicate the experience as accurately as possible.

This fork fixes some perceived issues with DOSBox and adds new features such as
Wayland support, PowerPC/POWER dynamic recompilation, and FluidSynth MIDI.
Other features may be removed: for example, physical CDs can no longer be
played, only emulated media.

Graphical emulation includes contemporary text mode, Hercules, CGA, EGA, VGA,
VESA, S3@tie{}Trio@tie{}64, and Tandy hardware.

Emulated legacy sound devices range from a rudimentary `PC speaker' buzzer to
the once state-of-the-art Gravis Utrasound sampling sound card.  The default is
a SoundBlaster 16 providing 16-bit stereo sound.  MIDI is forwarded to the host
through an emulated MPU-401.

An emulated hardware modem is also included, letting one host or dial a
@acronym{BBS, Bulletin Board System} across the Internet, network over IPX, and
emulate a serial nullmodem over TCP/IP.")
