TuxNES is an emulator for the 8-bit Nintendo Entertainment System.  It is
based on Nestra, a great public-domain NES emulator by Quor.  TuxNES adds many
features not found in Nestra, and uses a more collaborative development model.
Enhancements to Nestra often find their way into TuxNES.  Enhancements to
TuxNES don't generally find their way into Nestra due to licensing
restrictions (since pieces of TuxNES are generally copyrighted by their
authors, and covered by the GNU General Public License), although similar
changes by the same authors sometimes find their way back into Nestra.

TuxNES requires an x86-family processor.

If you would also like to install GTuxNES (a graphical launcher for TuxNES),
download its source tarball and place it in the same directory as the
SlackBuild. The GTuxNES homepage is http://www.scottweber.com/projects/gtuxnes/

The GTuxNES site appears to be down, but the source is mirrored here:
