======================================================================
Quick Tips:
======================================================================
Under Windpws 95, if you have a CD ROM that does not support
Autoplay, please click on launcher.exe.
--------------------------------------------------------------------
After triggering a trap, it takes a short time for the signal to
get through the security system to the trap. If you switch to a new
room too quickly, the trap won't activate. If you wait to switch
rooms until you see the trap start to move, you won't be bothered by
this problem. The Martins have complained about this to the
contractor, Russell and Oliver, but it hasn't been fixed yet.
--------------------------------------------------------------------
When you save a game it is put in the file C:\DIGIPIX\NIGHTRAP.SVG.
When you restore a game this file is also used.
Using DOS or Windows 95, you may rename this file. Additionally the
Night Trap game program (NT.EXE) will take a "/R" (for Restore)
command line argument and a file name. In these examples, the
CD-ROM with a Night Trap disc is assumed to be drive D:. Using
these features makes restoring a game on disc 2 easier.
Suppose you have saved a game that is in the second disc. You can
put the second disc in the CD-ROM drive and at the DOS prompt type:
C:>D:
D:>NT R
This will restore the saved game without asking for disc 1.
To save several different games, first, save a game and quit.
Second, in DOS, rename the saved game file with a DOS command like
this:
D:>RENAME C:\DIGIPIX\NIGHTRAP.SVG GAME1.SVG
(Where "GAME1" is a name you choose)
Now you can restart the saved game with the DOS command:
D:>NT R C:\DIGIPIX\GAME1.SVG
=======================================================================
Known Problems and Solutions:
======================================================================
Game doesn't work with QDPMI.SYS and freezes
soon after displaying the title screen.
--------------------------------------------------------------------
QDPMI.SYS (from QEMM) and other virtual memory managers, other
than the virtual memory manager included in Windows 95, do not
permit Night Trap to run properly. Please add a REM
followed by a space to the beginning of these lines from your
CONFIG.SYS, if you are still using one of these pieces of old
software.
--------------------------------------------------------------------
Game doesn't work with some EMM386 command line.
--------------------------------------------------------------------
The EMM386 that came with MS-DOS 6.0 has various bugs.
If possible, comment out the EMM386 line from your system.
With DOS 6.0 to 6.22, if you specify the command line for EMM386
as something like "EMM386 1024 RAM" then Night Trap thinks
that the amount of memory available is the amount of Expanded
memory in this command line.
Edit your CONFIG.SYS to either:
a) Don't use EMM386
b) use EMM386 with no parameters
c) EMM386 8192 RAM (if you have enough memory)
d) EMM386 3000 RAM
We normally use Extended memory, but when EMM386 6.0 is running
we use expanded memory. More memory is preferred because
certain video sequences are not shown on a 4 meg system.
--------------------------------------------------------------------
Game doesn't work. DIAG mistakenly reports your
computer has a speed of '0 MIPS'.
--------------------------------------------------------------------
Timer 2 is not working on your computer.
Solution: try "NT f" instead of "NT" on the command line.
--------------------------------------------------------------------
Ugly color flickering during video sequences.
--------------------------------------------------------------------
If the program flickers when running in MS-DOS, type "NT f"
instead of "NT" on the command line to run the game. (F stands for
"flickerfree").
--------------------------------------------------------------------
Keyboard freeze (seen on Zenith brand computer).
--------------------------------------------------------------------
Symptom: the program is running, but the keyboard stops responding.
From DOS, use the command "NT k" (K stands for keyboard)
instead of "NT" to run the game.
You may combine 'k' with other options (e.g. "NT k f" or "NT f k").
======================================================================
Windows 95 Problems:
======================================================================
The program may run poorly under Windows 95: conversely, it may
run with video flicker under DOS.
--------------------------------------------------------------------
Solution: Try running in the other mode.
--------------------------------------------------------------------
Windows 95 displays the blue "Error reading CD" screen
during gameplay.
--------------------------------------------------------------------
Solution: Follow the directions on the screen. Make sure the
right disc is in the drive and hit RETURN.
--------------------------------------------------------------------
With some CD ROM drivers, Windows 95 displays the blue
"Error reading CD" screen when you are trying to switch
disks and when Night Trap has ejected the disc.
--------------------------------------------------------------------
Solution: Press escape. The blue screen is superfluous.
--------------------------------------------------------------------
Windows 95 gives you the "Unable to load .DLL" message instead
of launching the game when you insert the disc or double click
on the disc icon.
--------------------------------------------------------------------
Solution: Open the disc by clicking with the RIGHT MOUSE button,
and double click on "NT.PIF". This will run the game, skipping
autoplay.
--------------------------------------------------------------------
Windows 95 does not automatically run the game. Clicking on
the disc opens it.
--------------------------------------------------------------------
Solution: Click on the "launcher" icon. If that fails, click
on "NT.PIF".
--------------------------------------------------------------------
"Run in DOS" does not work... no mouse is present or the program
immediately returns to Windows 95 after launch.
--------------------------------------------------------------------
It is often difficult to get the "Run in DOS" option to work:
A Windows 95 computer may no longer be loading MSCDEX,
or a mouse, or neccessary device drivers for your DOS session.
To make "Run in DOS" work (if it doesn't):
The lines Windows 95 commented out of your AUTOEXEC.BAT and
CONFIG.SYS will be REM'd out- they also will appear in
AUTOEXEC.DOS and CONFIG.DOS.
Either:
1) Edit AUTOEXEC.BAT and CONFIG.SYS and put them back or
2) Set up your computer for multi boot so you have the
option of using your old or your new drivers.
3) Call Customer Support at (415) 345-0445.
--------------------------------------------------------------------
Sound Problems: run SETUP if you have any problems, even glitching
or echoes.
--------------------------------------------------------------------
1) Some sound cards (for example, Gravis) require a higher
interrupt rate to operate from a DOS box. Windows 95 may
interfere with the operation of these cards. You must check
the "run in DOS" box on the launcher and run in "Dos
compatibility mode" if using Windows 95.
------------------------------------------------------------------
2) Certain Sound Cards, such as the Diamond SonicLX card and the
MediaMagic soundcard, can be configured using a utility that
comes with the card to be a SoundBlaster or a Windows Sound
System card. The utility is variously named ISPINIT.EXE or
SONIC.EXE.
The program cannot autodetect these cards when they are
configured in SoundBlaster mode. Furthermore, if configured as
Sound Blaster, you can only run the program once between
reboots. The second run will fail. Please configure these
sound cards in Microsoft Mode using the utility, type setup,
and specify that you are using a Microsoft Sound card,
-OR-
Note the IRQ, Port, and other information for the SoundBlaster
configuration. Type NT ask, and specify an old sound blaster.
Enter the port and IRQ, and note that the program will only run
once.
--------------------------------------------------------------------
If none of the programs run at all (you get DOS4GWPro Errors) try
running the PMINFO32 or RMINFO programs in the SETUP directory.
These may help explain to customer service what the problem is.
--------------------------------------------------------------------
You find it necessary to use one configuration for Night Trap
and a different configuration for some other frequently used
program.
--------------------------------------------------------------------
You can use features of DOS and Windows 95 to make this easier.
If you use DOS 6.0 or later, you can set up alternate boot
configurations. You can also get alternate boot configurations by
adjusting the BootGui=1 to BootGui=0 in msdos.sys under
Windows 95, and then making sure the AUTOEXEC.BAT runs "win" to
launch Windows 95 or not.
If you use Windows 95, you can copy the PIF files from the CD onto
your hard drive, alter the command lines and the .pif in their
properties method. (Note you must uncheck "read only" to make
changes.
--------------------------------------------------------------------
The DIAG program gives various measures of the performance of your
system that effect the quality of the game. Here is some
information about typical values.
--------------------------------------------------------------------
The average 25 Mghz 486 system performs at 15 MIPS. A typical
Pentium registers at 140 MIPS (138 MIPS under Windows 95).
An SVGA speed of less than 1,000 K per second is very slow.
Some fast computers, when given the wrong kind of video card,
perform abysmally in this category. A video card that
performs speedily on a slow machine may perform WORSE on a fast
machine!
A typical 25Mghz 486 performs SVGA at about 4,500 K per second; a
typical Pentium performs at 10,650 K per second.
A 2X CD drive should get at least 290K per second, or your drive,
or the disc, is defective or needs cleaning. You might try
inserting different discs while diag is running to see which it
is in this case.
Since Windows 95 has virtual memory, the amount of extended
memory reported will often be very large, usually larger than the
physical memory.
Also under Windows 95, the percentage of time spent reading the CD
is unreliably reported.
