SILENT HUNTER  V1.31 "READ ME" FILE:
------------------------------------------------------------------------
To upgrade either V1.0, V1.01, V1.11 or V1.2 of Silent Hunter to V1.31 use the 
following procedure:

1.  Place the PATCH.BAT and SH13.EXE files in your Silent Hunter 
directory on your hard drive (the default directory is C:\SILENT).

2. Run the PATCH.BAT file by typing PATCH at the DOS prompt.
     ******DO NOT RUN THE SH13.EXE FILE BY ITSELF!!!*******
****THE PATCH WILL NOT WORK PROPERLY UNLESS YOU RUN PATCH.BAT!!!****

3.  Run your new V1.31 of Silent Hunter as before, type SH at the 
prompt.  To run just the Scenario Editor type SE from the DOS prompt.
NOTE:  Run the Scenario Editor from the DOS prompt if you only have 
8 megs of memory.


MEMORY ISSUES.

IMPORTANT NOTE:  For those of you with 8 Megabytes of RAM, when there are many 
	         ships, contacts, and weapons being fired, in other words when 
	         things are getting very exciting, some of the sound effects 
	         may not play to conserve memory.  Adding new features to 
	         Silent Hunter has made us push the very limits of 8 megabytes.
                 The features added to Silent Hunter since V1.0 have enhanced the
                 simulation but the result is that there are now limitations on 
                 the functionality and stability of the game when running with only
		 8 Megabytes of RAM.  It is strongly recommended that if you play 
		 Silent Hunter with large scenarios that you consider upgrading your
                 system to 16 Megabytes of RAM or more.  

If you are running at a high time compression and are trying to 
steer the sub, fire torpedoes, or zoom in and out you may overwhelm the 
engine and cause a slow down or crash.  The function of time compression
is to get the sub into contact with enemy ships  Time compression was
NOT made to support regular game play i.e. steering the ship, firing 
torpedoes, or zoom in and out.

Be aware that if you load a Custom scenario from a source other than
SSI, that it may be too large for some machines.   Try loading it into 
the Scenario Editor, and use the Memory Gauge tool to check it 
against your system capability before you try to run it.		

CHANGES FROM V1.0 OF SILENT HUNTER

NOTE:  If you have Patrol Disk 1 or 2, or have upgraded to V1, V1.11 or V1.2 then you 
will already have the features listed below:
	
TWO SPECIAL MISSIONS- PHOTO RECON, AND LIFE GUARD DUTY.

PHOTO RECON:  You will receive photo Recon missions in campaigns via a
radio transmission. In addition to the radio message a red "T" icon 
will appear on the chart screen over the facilities to be photographed.
In order to successfully complete a Photo Recon Mission the sub must
move close enough to the target area.  A "red" light, located in the 
TBT or Periscope viewing area will indicate the sub is close enough to 
take a picture.  The "TAB" key is used to take the photograph.  The 
user will know the mission is accomplished when the "T" icon 
disappears from the chart screen, which will be accompanied by a voice 
and text message stating "Mission completed, sir."  Scoring - Each 
completed Photo Recon mission is worth 500 points at the 100% 
realism setting.  NOTE:  Photo Recon missions can only be accomplished 
during daylight hours.  It is best to remain completely zoomed out (1x)
in order to locate the area that needs to be photographed.

LIFE GUARD DUTY:  Like the Photo Recon mission, in campaigns, the user 
will receive the orders via a radio transmission.  As with the Photo 
Recon mission, a red "T" icon will appear over the port that will be 
bombed by American aircraft.  The user can watch the airstrike in 
progress while sitting off the coast of the target area.  The bomber
group will show up on SD radar, and on the chart screen.  After the 
airstrike is finished, blue triangle icons will appear indicating the 
approximate location of the downed pilots.  When the pilots are 
spotted the user will receive a voice and text message stating "Downed 
Pilot spotted".  As the sub closes within 200 yards of the downed 
aviator "We're close enough for a rescue, sir!" voice message and text 
message will inform the user that the pilot can be extracted.  At which 
time the sub must slow down to 5 knots or slower and  then hit the "E"
key OR the sub can run over the pilot in order to  pick him up.  
Scoring- each pilot saved is worth 200 points at 100%.  NOTE:  Pilots 
can only last a limited time in the water before being captured or 
succumbing to the elements.  So it is entirely up to you if one of 
America's valiant sons resides with NEPTUNIS REX in his watery domain 
or perishes in a prison camp.

	
SUB VS. SUB:
Sub vs. Sub will be encountered in the campaign as well as single 
scenarios.  There are three types of subs, all of which can be seen in
the ship ID book under PATROL CRAFT.  NOTE:  In single scenarios if the
enemy is elite, the player may find that they are being stalked first.
When firing a torpedo at a Sub do not forget to adjust the depth of the
torpedo using the TDC.

RADIO LOGBOOK:
The Radio Logbook is accessible from the Captain's Quarters or by 
hitting Alt-F9.  The user will be given a date, a time and a location 
of Life Guard or Photo Recon missions.  

ENHANCED ENEMY AIRCRAFT ATTACKS:
Aircraft with bombs will bomb first and then strafe.  At easier realism
level settings a plane may not have guns and will simply circle when 
out of bombs.

SUBMARINE ANTI-AIR ROUTINE:
AA guns are manned from  the 1MC menu, and will automatically fire at 
the nearest air target in range.

DECEPTION OPTION (DEBRIS)
This option, also located on the 1MC (hotkey "M"), allows the user, in 
an act of desperation, to launch debris out of the sub in order to fool
the escorts.  This move only has a 30% chance of working with novice 
enemies, and 10% with veteran, and 2% with elite crews.  NOTE:  This 
only works once and after that serves only to mark your location.  
Debris is only shown on the chart screen with Realistic charts turned 
off.

IMPROVED SHIP ID BOOK:
The book now stays open to the page previously displayed.  Index tabs 
have also been included.
*BB - Battleships
*CV - Aircraft Carriers
*CA - Heavy Cruisers
*CL - Light Cruisers
*DD - Destroyers
*DE - Destroyer Escorts
*PC - Patrol Craft (Includes Submarines)
*MR - Merchant Ships
	
NIGHT TIME LIGHTING:
To add more of a touch of realism we have provided red interior night 
lighting.  Night lighting will automatically come on as night falls, 
and off as day breaks.  NOTE:  You can also toggle the automatic option
ON or OFF through the Alt-O option.  From the 1MC ("M") you are given
the option to turn it ON or OFF at any time of the day.

CREAKING SOUND WHEN DEEP:
As the sub proceeds past the recommended maximum depth the your 
submarine's hull will start to creak from the enormous pressure.

IMPROVED TIME COMPRESSION:
We have increased the time compression maximum to up o 2048 times.  
So now you can fly around the Philippine islands in 1941.  NOTE:  As
in version 1.0 you will experience slow down when the CPU load is too 
high to run it.   The compression rate will be reduced when you are 
near enemy contacts or have either radar, sonar or visual contact with
ships.  

NEW REPORT DIALOG IN TACTICAL CHARTS:
Placing the cursor over a ship icon in the tactical chart will produce
a report dialog.  The dialog should have bearing, speed, range, 
solution, and identification based on solution.  At lower solutions, 
ships will be unidentified.  Placing the cursor over a port on the 
strategic chart will produce a report dialog.  The dialog will have a 
name, latitude / longitude, occupier, and size information.

IMPROVED CONVOY AI WHEN UNDER ATTACK:
When the sub location is known the convoy will,
a)  turn away from the sub (evasive action)
b)  some of the convoy members will panic and separate from the convoy.


Bugs Addressed in V1.01, V1.1 and/or V1.11:

	Ships disappearing on photo recon mission fixed

        Game crash during Photo Recon mission (Tab-Key crash)
        
	Ships riding low or floating has been fixed

	Destroyers not firing when they have run aground fixed

	Number of sonar contact reports repeating has been reduced	

	Phantom ships appearing has been eliminated.

	Excessive use of compressed air has been fixed. 

	Display problems in the chart screen have been reduced.

	Erratic torpedo runs. (Note:  Sometimes torps will still 
	detonate without a message).

	Patrol craft behavior in port not firing on sub.  
	(Note:  There is still erratic behavior by ships in harbor 
	from time to time.  Ships that are anchored will not react.)

	Multiple crash bugs have been eliminated.

	screen the "T" key takes you to the torpedo controls and the
	"N" key brings up the navigation controls.

new feature provides the user the ability to save individual scenarios at
any point during play.
