TUNNEL B1  -  Additional Information


(1)	PAUSE/BREAK key problem
If the key labelled PAUSE/BREAK is pressed in-game, the selected primary
weapon will be fired and the booster activated (if one is present).

(2)	Map entry screen problem
If the player is holding down a key (eg. Accelerate) when they bring up the
map, upon returning to the game, if the key is still depressed then its
function will be ignored.  The user must repress it in order for it to work.

(3)	Problems with CD music
Occasionally it was noted that the CD music did not loop at the end of a
track.  This seemed to be related to certain machine configurations and we
have found that if the user continues playing then the music will begin again
after a short time.

(4)	Problems with CD music #2
When the game was played on a machine with a Toshiba 8 speed CD ROM drive,
about 5% of the time the CD music was heard to play at 4 times its original
speed upon starting a game.  This problem will correct itself when the music
loops.

(5)	Warbling/corrupted music and sound effects
If the player experiences distorted music or effects whilst using TunnelB1,
the following process should be carried out to rectify it.
	(i)	Enter the TUNNELB1 directory on drive C:.  This is done as
        follows
			C: <ENTER>
			CD\TUNNELB1 <ENTER>
	(ii)	The user must now edit the programs sound file, to do this
        type
			EDIT B1.INI <ENTER>
	(iii)	The following information should be displayed
			"MAXVOICES 31
			  SNDRATE 22050"
        Move the cursor to the second line down, and change the value 22050
        to 11025.
        The file should now read
			"MAXVOICES 31
			  SNDRATE 11025"
        (iv)    The file should now be resaved.  To do this hold down the ALT
        key and press F to bring up the file menu at the top of the screen.
        Move the highlight bar down the menu to highlight the SAVE option and
        press ENTER.  The file will now be rewritten.  The user can now return
        to DOS by highlighting the EXIT option in the file menu.
        (v)     If the user now runs the game, the sound problems should be
        corrected.
If the problem persists the player should run the program SMARTDRIVE.  This
is done by entering the command "SMARTDRV" at the DOS prompt.

(6)	Problems during loading
If the game appears to lockup during loading (ie. it remains on a black or
intermission screen for over 60 seconds) the user should try ejecting the CD
ROM, then re-inserting it.  The program should now continue to load.

(7)	Problems autodetecting sound cards
If the player attempts to autodetect their soundcard, and the program locks
up or detects incorrect information, the user should re-attempt autodetection
as the machine will try to find the second best match.  If problems still
occur then the user will have to manually set up their sound card.

(8)	Problems running game in high res
The program requires a VESA compatible video card that is capable of running
640*480 in 16 bit for high res mode.  If your card is unable to do this the
option for high res will not be available in the DISPLAY OPTIONS menu.  The
video cards that this problem was seen with were
	Number 9 Imagine 128 (PCI)
	Diamond Edge 2000 (PCI)
	Diamond Viper 9100 (PCI)

(9)	Midi set up during installation
When the user is setting up their sound card during installation, they will
see options to select a digital device and to select a Midi device.  The
player does not have to set up the Midi device as the game features only
digital sound and music.  Because of the use of digital sound only, users of
cards that only support Midi (eg. The Roland SCC1 sound card) will not get
any music during the introduction, all they will be able to hear is the CD
music in the game.

(10)	Problems with sound cards
The following sound cards experienced problems with the game
	(i)	Quickshot Sound Machine 16-This sound card had to be set up
        manually
	(ii)	Diamond Sound Sonic-This sound card had to be set up manually
        (iii)   Adlib Gold-This sound card had to be set up manually, in
        addition it was noted that the test sample in the sound setup program
        sounded corrupt when played, although the sounds in the game worked
        correctly.

(11)	Problems with juddery animation during introduction
When the game was run on a machine with a very slow video card (ie. Trident
8900D (ISA) video card) then the introduction animation's would often pause
every few seconds and the introduction would not run to its true length.
This problem is caused by the limitations of the hardware, so if it is seen
the only real solution to it is to buy a better video card.

(12)    High res mode limitations
When the game is being run in high detail mode, the user will only be able to
select normal in the games difficulty options.
This is true whenever the player changes the difficulty level to hard (eg. if
a game is started in low res, high difficulty, and the detail level is
changed to high at the end of a level then the difficulty level will revert
to the default of normal).

(13)    Problem running the game through Windows 95
This program was not created to run through Windows 95 (either desktop or DOS
prompt), if the player experiences problems whilst doing this then they
should shut down into a clean DOS environment.  This is done be moving to the
START button on the bottom left corner of the desktop and selecting the
option SHUT DOWN.  A menu will now be displayed and the option RESTART
MACHINE IN MS DOS MODE should be selected.  The machine will now shut down
and return to a DOS environment.  If the player has problems seeing the CD
drive, they should contact their hardware vendor regarding the installation
of DOS based CD ROM drivers.  Alternatively a boot disk could be created, the
process of which is as follows

MAKING A WINDOWS 95 BOOT DISK


NOTE:  This method should not be used for machines that have SCSI peripherals
or that have compressed drives.  If you are unsure about either of these
points please contact your hardware vendor.



(1)	When in Windows 95, move down to the START button in the bottom left
corner of the screen.  Select from the PROGRAMS group the MS-DOS PROMPT.
The following message should be displayed

"Microsoft(r) Windows 95
	(c)Copyright Microsoft Corp 1981-1995
C:\WINDOWS>"


(2)	Insert a blank diskette into your machines 'A:' drive ensuring it is
not write protected.  Enter the following text.

	CD\	<ENTER>

	FORMAT A:/S	<ENTER>

You should then see the message

"Insert new diskette for drive A:
and press ENTER when ready..."

Pressing ENTER will start the formatting of the disk.  Upon completion of
the format the message

"Volume label (11 characters, ENTER for none)?"

will be shown.  Press ENTER to get past this and then enter 'N' in answer to
the question

"Format another (Y/N)?"


(3)	The machine should now be displaying the 'C:\>' prompt.  Now type the
following lines

	COPY CONFIG.SYS A:	<ENTER>

	COPY AUTOEXEC.BAT A:	<ENTER>

	A:	<ENTER>	

        EDIT AUTOEXEC.BAT       <ENTER>


(4)	Find in the text a line similar to the following

"C:\MOUSE\MOUSE.EXE"    (The mention of MOUSE being the important point)

and add the letters "LH " at the start of the line (if these letters are
already present proceed to step 5).  Using the above example the line would
now read

"LH C:\MOUSE\MOUSE.EXE"

N.B.  If this line, or one similar, is not present contact your hardware
vendor requesting a DOS based mouse driver for your system.


(5)	Next find the line that contains the word "MSCDEX.EXE", an example
being

"C:\WINDOWS\COMMAND\MSCDEX.EXE /D:MSCD000"

and again add the letters "LH " at the start of the line (if these letters
are already present proceed to step 6).  The example would now read

"LH C:\WINDOWS\COMMAND\MSCDEX.EXE /D:MSCD000"

The user is advised to note down the letters after the "/D:" section of the
above line (in this case it would be "MSCD000") for uses described later.

N.B.  If this line, or one similar, is not present contact your hardware
vendor requesting a DOS based CD ROM driver.


(6)	Now if the user has a SOUNDBLASTER sound card or compatible they
should find a line similar to the following:

"SET BLASTER=A220 I5 D1"


(7)	Next find a line similar to the one below

"PATH=C:\WINDOWS; C:\WINDOWS\COMMAND"

If this line is different or not present then edit or add it.


(8)	The user should now remove all the other lines in the file apart
from the four outlined. Therefore in our example the file would be as follows:

"PATH=C:\WINDOWS; C:\WINDOWS\COMMAND
LH C:\MOUSE\MOUSE.EXE
LH C:\WINDOWS\COMMAND\MSCDEX.EXE /D:MSCD000
SET BLASTER=A220 I5 D1"


(9)	Next hold down the 'ALT' key and press 'F' to bring up the FILE menu.
From this select the SAVE option.  The file will now be saved to your
diskette.


(10)	Hold down 'ALT' and press 'F' once again, but this time select the
OPEN option.  A window will open asking for a file name, enter the following

A:\CONFIG.SYS

and press ENTER.  A new file will now be opened.  


(11)	Within the file the user should see the following line

"DEVICE=C:\WINDOWS\HIMEM.SYS"

If this line is not present it should be entered by the user at the very top
of the screen.


(12)	The user should next look for a line similar to the following

"DEVICE=C:\WINDOWS\EMM386.EXE RAM"

If this line is not present it should be entered below the previously
found/entered HIMEM.SYS line.  If the line is differently worded to that
above it should be altered to match it.


(13)	Next find lines similar to the following

"DOS=HIGH, UMB
BUFFERS=15,0
FILES=30
LASTDRIVE=Z"

If these lines are not present or are differently worded alter them to match
the examples given.


(14)	The next thing the user needs to find is the line used to configure
the CD ROM drive.  In step 5 the user was asked to note down the text after
the "/D:" letters of a line in the AUTOEXEC.BAT file (in our example it was
MSCD000), and this is where it is needed.  Find the line that carries the
same text, for example

"DEVICE=C:\CDROM\SGIDECD.SYS /D:MSCD000"

This is the line used to control the CD ROM drive, after the word DEVICE the
user should add the word HIGH (with no spaces before or after the word) if it
is not already present.  Our example would therefore read

"DEVICEHIGH=C:\CDROM\SGIDECD.SYS /D:MSCD000"


(15)	The user should now remove all the lines that have not been covered
in steps 11-14.  Our example file would now look as follows.

"DEVICE=C:\WINDOWS\HIMEM.SYS
DEVICE=C:\WINDOWS\EMM386.EXE RAM
DOS=HIGH, UMB
BUFFERS=15,0
FILES=30
LASTDRIVE=Z
DEVICEHIGH=C:\CDROM\SGIDECD.SYS /D:MSCD000"


(16)	Next hold down the 'ALT' key and press 'F' to bring up the file menu,
from here select the SAVE option.  The file will now be written to the
diskette.  Once again hold down the 'ALT' key and press 'F', but this time
select the EXIT option.


(17)	The machine should now have returned to the "A:\>" prompt.  From here
type

	EXIT	<ENTER>

to return to Windows.


(18)	Save your work and close down all open applications, then shut down
Windows.  The message "IT IS NOW SAFE TO TURN OFF YOUR COMPUTER." should now
appear.  Now press the RESET button on the front of your machine (making sure
that the diskette is still in your A: drive).


(19)  	The machine will now restart, and should boot from your freshly
created disk.  Once loading has finished the machine should display the "A:\>"
prompt rather than the usual Windows 95 startup screen.  If your machine does
display the Windows 95 screen as normal and not the DOS prompt then contact
your hardware vendor.


(20)	Follow the games loading instructions.  

This boot disk can be used with all DOS based games.  If you wish to return
to Windows simply remove the diskette from drive A: and restart the machine.

If your machine still has problems please contact your hardware vendor for
further information.
