WHAT YOU NEED.

To get the patch update working on your system you will need:
	1) Xwing, or the Tie fighter demo configured for 
	   General Midi with Soundblaster.
	2) A Gravis Ultrasound card (preferably with 1 MB
	   memory, they are complex patches).
	3) The latest Megaem drivers (version 2.03).
	4) The patch updates (available at the Gravis BBS.)

			    SETUP

	To set up the update follow these steps.
1. Copy the Xwing.ini file to your ultrasound directory.
   (The same directory where ultrasnd.ini resides).
   Overwrite your previous Xwing.ini file.

2. Copy xwing2.pat to your patch directory.
   (Usually the MIDI subdirectory).
   Overwrite the previous xwing2.pat.

3. Go to where you installed Xwing or the Tie Fighter demo.
   There you will find a subdirectory called RESOURCE.
   The files sfx.lfd and sfxgmd.lfd should be replaced with
   the ones that came with this update. Make sure you back
   them up before replacing them.

4. To use the updated patches follow the directions that
   came with the first patch set. (backup ultrasnd.ini, 
   then rename Xwing.ini to ultrasnd.ini)

5. Load Megaem and Emuset

6. Run Xwing, or the Tie fighter demo.

7. When done playing don't forget to rename Ultrasnd.ini,
   and your Ultrasnd.ini backup file back to their original
   names.  Failure to do so will keep loading these patches 
   for any program that loads patches through the Ultrasnd.ini
   file.

	You can simplify the process by writing a batch file
to take care of all the renaming, and loading of Megaem and
Xwing.  Or if you have multiple configurations under DOS you
can include the renaming statements in your autoexec.bat file.

			BACKGROUND
   
   LucasArts let slip a little bug with Xwing, that made it's way 
into the Tie fighter demo.  Although I brought it to their
attention they haven't done anything about it much less fix it.
   
   The problem lies in the targeting computer when using General MIDI.
(Remember the sound you got when you used SBOS?).  The exact problem
is that the part of the file (sfxgmd.lfd) that is responsible for the
targeting computer sound is garbled with nonsense.  If you ever noticed
your computer slowing down badly whenever the targeting computer was
being used, guess what was responsible.
   
   Luckily the file is made up of MIDI type 2 sequencer files 
(loadable by certain sequencers such as Voyetra SP gold or winjammer.)  
It was an easy matter to fix the problem so I did it on my own. 
   
   While I did that I also made it so you can play the Xwing 
engine sounds and the flute at the same time. I also made the ion 
blasts louder.  That is the sfx.lfd file.
