Description:

XU4 is a recreation of the classic computer game Ultima IV. The
purpose of the project is to make it easy and convenient to play on
modern operating systems. xu4 is primarily inspired by the much more
ambitious project Exult. Linux is the primary development platform,
but it should be trivial to port to any system with SDL support.

XU4 isn't a new game based on the Ultima IV story -- it is a faithful
recreation of the old game, right up to the crappy graphics. If you
are looking for a game with modern gameplay and graphics, this is not
it -- yet. New features that improve the gameplay and keep with the
spirit of the original game will be added.

The actual data files from Ultima 4 are loaded at runtime, which means
that a copy of Ultima 4 for DOS must be present at runtime.
Fortunately, Ultima IV is available as closed-source freeware on the
internet (legally). A copy is mirrored at xu4.sourceforge.net.

It is also available from
http://plf.zarb.org,
http://www.zip.com.au/~mfleming/ultima/u4download.html,
http://members.tripod.com/~hardwire1/ultima4.zip,
http://www.members.aol.com/tommage/UltimaPage/ultima4.zip, or
http://www.nightfall.org/~deep/ultima/main.html among many other
sites.

Once downloaded, it must be unzipped in /usr/share/games/u4/ultima4
