Comments and Errata for the System Shock Playable Demo, v1.0
============================================================
1. Sound stuff:  For space reasons, we have not included our install
program which would automatically set your System Shock configuration file
appropriately for your sound card.  The demo comes default configured for
no sound or digital effects.  If you want either sound or digital effects,
you will have to edit your cyb.cfg file yourself.  In cyb.cfg, you will
find, among some other things, the following lines:

digi_card -1
digi_io -1
digi_dma -1
digi_irq -1
midi_card -1
midi_io -1
midi_irq -1

digi_card and midi_card are the big ones; they control what sound or
effect card the game thinks you have.  You can set midi_card or digi_card
to the appropriate value from the table below:

SoundBlaster                    1
SoundBlasterPro (old)           2
SoundBlasterPro (new)           3
SB16                            3
Adlib                           4
General Midi                    12
AWE32                           13

midi_irq and midi_io can be set to the appropriate value of your IRQ and
I/O base address, respectively.  Similarly, digi_io, digi_dma, and
digi_irq can be set to your digital I/O address, DMA, and IRQ.  These
values are in decimal, which may be a bit confusing when setting digi_io
and midi_io since those values are normally expressed in hex.  Note that
if you leave these values as their original -1, System Shock will attempt
to use the defaults.  

So, if you have a vanilla SB16 (card 3), with all default settings, the
sound part of your cyb.cfg would look like:

digi_card 3
digi_io -1
digi_dma -1
digi_irq -1
midi_card 3
midi_io -1
midi_irq -1

If you had an SB16 (card 3) on digital IRQ 7, and a Waveblaster
daughterboard for MIDI (card 12), the sound part of your cyb.cfg would
look like:

digi_card 3
digi_io -1
digi_dma -1
digi_irq 7
midi_card 12
midi_io -1
midi_irq -1

Gravis Ultrasound users:  Although the actual shipping version of System
Shock that will be available in stores does support the Gravis Ultrasound,
the playable demo does not.  We apologize, but the GUS support had to be
removed from the playable demo for space reasons.  

2. Memory:  System Shock requires 4 Megs of memory, including approximately
500k of low memory, in order to play.  System Shock will attempt to use
more memory than that for additional features, such as higher resolution
texture maps, blended bitmaps, and improved cache performance.

3. Playing the Game:  System Shock comes with some on-line help tools to
help you learn to play the game as quickly as possible.  When you first
start the game, a screen overlay will appear, labelling the various
regions of the game screen.  This overlay can be brought up again by
hitting Alt-O.  In addition, there is an automatic on-line help system
that will advise you on how to play the game and manipulate the interface
during the early stages of the game.  It will turn off automatically after
leaving the initial area.  If you want to turn it back on again, use
Alt-H.  There is also a list of keyboard commands, that can be accessed
via the ? key.  These keyboard commands are also in help.txt, in the same
directory as this file.

4. Changes from the Real Game:  Since this is, well, a demo version of the
game, we've disabled saving and loading.  Needless to say, in the real
version of the game, you can save and load games.  For space
considerations, a couple of features regarding the "look" of the game were
removed for the demo.  Specifically, there are fewer unique textures in
the demo than there are in the real level 1, and some anti-aliasing
techniques that work in the real game are not in the demo.  A few
creatures and sound effects that are present in the full game have also been
removed for the demo.

5. Running the Game: To run the demo, just type sshock at the DOS prompt
after you are done reading this file.  Then select "New Game", set your
difficulty levels, and have fun!  Remember that difficulty level 0 in a
given category means that we have attempted to remove that element as
much as possible.

6. We hope you enjoy this demo!  If you do, the full game should be available by
October 1st at a computer software retailer near you.
