Paul Brett introduces the XU4 documentation
If you have read this issues GamesWorld column you will know that XU4 is a version of the original Ultima IV game updated to run on modern computers. Ultima IV was a classic game at its launch in 1985, and went on to spawn many more versions over the years.
At the start of Ultima IV
You need to fulfil a major quest and must explore the lands of Brittania, and explore a number of deep dark and above all dangerous dungeons. Even above ground you aren't safe as hoards of rouges and cutthroats are ready to attack you at a moments notice.
Time for a fight
Ultima IV is a big game, and you will need all the help you can get, so we have reproduced the supplied documentation, and the original history of Britannia below, good luck, you are going to need it!
The actual data files from the original 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.
In this RISCOS distribution the Ultima4 file has been downloaded and place in the sub-directory Ultima4.
The Ultima IV VGA upgrade has been applied to the provided files distributed here.
At the title screen, a configuration menu can be accessed by pressing'c'. Here, the screen scale, filter, volume and other settings can be modified. Note: the game must be restarted for the new settings to take effect. These settings are stored in the file UnixEnv$HOME/.xu4rc.
xu4 also accepts the following command line options:

This RISC OS port
Ported to RISCOS by Alan Buckley October 2003. This program is 32 bit compatible and requires RISCOS 3.6+. Digital Renderer module (available from http://home.t-online.de/~zarquon) may be installed in System:Modules if sound is required. The Music requires the !SDLSample directory to have been seen by the filer (available from http://www.chocky.org/unix/).
The !UnixHome application (available from http://www.chocky.org/unix/) must have been seen by the filer.
You will also need to have installed the SharedUnixLibrary 1.0.2 which is available from the Unix Porting Project (http://www.chocky.org/unix/) and the GCC pages.
Part of the Unix Porting Project. Support for this program under RISC OS is only offered to subscribers. See http://www.chocky.org/unix/ for more information.
