Does your New Game Run OK?
........or do you spend three hours re-configuring your system,
only to be told that a patch disc is an essential requirement and
has been since 1989?
A bit of semi-technical, quasi-nerdic rant from MerC
There is no doubt that PC games have become more and more complex,
and hence more and more demanding of system and system resources.
Although they may specify minimum requirements of a 386SX, DOS 5.0
and 2Mb RAM, this set up will hardly ever allow your new purchase
to run at its best. In fact, a fair few of them would still run
slowly on a 486 DX2 with 4Mb. A decent video card (1Mb minimum)
and sound card (100% Soundblaster compatible) are more-or-less
essential requirements, and for the latest a double-speed CD ROM
player is needed (these are dropping in price all the time - what
cost £200 in January should now be obtainable for £170). A decent
memory manager (e.g. QEMM) helps, and you may need to know how to
set up a boot disc properly (the instructions in magazines such as
PC Player are inadequate. Use their method, and you often end up
with no access to your compressed drive(s) and less conventional
memory than you had before). It also helps a great deal to know
how to manipulate those twin terrors of the PC world :
autoexec.bat and config.sys. (Should you spend a few hours
familiarising yourself with such intricacies, you might be
surprised to find you are more aware of what is going on than the
youth at the end of a 'technical help-line').
It is also becoming clear that amongst the software big-boys,
cynical profiteering is the order of the day. Why are games so
expensive in the UK? Why is the ostensibly cheaper CD so much more
costly than eight or nine high-density floppies - especially when
CDs cannot be pirated in the same way as discs? Games are issued
with grossly inadequate testing, requiring time-consuming
obtaining of patch discs and undocumented instructions. I am not
surprised at the constant whining of software companies ("Piracy
is costing us £1.2 billion a year, (...which could be spent paying
your directors at the water-company levels?). No wonder every whiz
kid worth his salt takes great delight in hacking and cracking. I
suppose they see it as the punter getting a bit of his own back.
Pirates are thieves, I do not dispute - but so are cowboys.
My first (but far from only) experience of undocumented but vital
set-up requirements was with a passably playable game called The
Legacy. After ensuring that all the memory needs were being met,
and all instructions followed, it still would not run. It
transpired that NUMLOCK has to be set to OFF before installation.
Nowhere was this mentioned, and it is not exactly an obvious
prerequisite. (I still don't understand why it stops the mouse
driver loading properly). It was only a chance remark from the
receptionist at Microprose that put me on to it.
I thought it might be interesting to tabulate the afflictions,
some malignant, some benign, of the various games I have started
(and sometimes finished) over the last few months :
Game Tweaks
---- ------
Ultima Underworld l update disc required (1)
Ultima Underworld ll patch disc required (2)
The Legacy numlock OFF (3)
Shadowcaster mouse driver in config.sys (4)
The Elder Scrolls : Arena patch disc (5)
The 7th Guest VESA driver needed (6)
Crusaders of the Dark Savant wrong instruction after
installation (7)
Return to Zork none (8)
Dragonsphere none (8)
(1) Two fatal bugs, though you can continue in all innocence until
about half-way through the game. Your inventory then starts
irremediably to corrupt. Patch requires you to begin again (!)
(2) Runs very slowly (486 DX 33MHz) when NPCs around. Patch disc
helps, but not much.
(3) A very simple, but undocumented requirement. With numlock ON
(a common PC default) the mouse freezes. Game has to be booted
with NUMLOCK set to OFF.
(4) Shadowcaster is very memory hungry. (QEMM helps). In spite of
having the required space, it would not run until I changed my
mouse driver loading from a mouse.exe line in autoexec.bat to a
DEVICE=mouse.sys line in the config.sys file. No idea why - seems
peculiar to my set-up.
(5) A large number of bugas (I leave this typo uncorrected) and
inconveniences fixed by the patch. Game cannot be finished without
it. See Review in this issue.
(6) A VESA driver needs to be loaded. A variety of these to suit
your model is supplied on request on a patch disk and can be
copied to hard drive, then loaded during boot-up from a line in
your autoexec.bat file. Seems to do no harm to leave it
permanently in place.
(7) To play after installation, just type DS.
(8) Hoo-blooming-ray.
Most incompatibility problems seem to stem from the sound card.
For some reason, games programs are able to detect which video
card you are running and adapt accordingly. This versatility
rarely, however, extends to the sound card. (Apparently there is a
much greater variety of sound cards in existence). For a start,
your card should be Soundblaster compatible (most are, up to about
98%) set with the settings the game needs. Some can determine and
use your settings, but others expect computer novices to set DMAs,
IRQs etc. and is sheer laziness on the programmer's part. These
settings are usually asked for at the end of a long installation
procedure, and I'm sure are a cause of constant dismay. Before
installing any game : read the technical documentation supplied.
(This is often around 4-5 pages in length, which says
something..). Get to the C: > prompt in DOS, and type Edit
autoexec.bat. When the .bat file appears, take a note of the
numbers after SET BLASTER=. These will be something like A220 I2
D0 T4. The installation usually only needs you to enter the first
two or three.
A final piece of advice : learn how to boot up with a MS-DOS Menu
from config.sys. This means that you will not need to load any CD
ROM device drivers (which occupy valuable memory) unless you are
going to use CDs. The following table gives you some idea of
memory allocations that work.
(486 DX 33MHz)
Route(1) Conventional(2) Kb Free EMS(3) Kb Loaded TSRs(4)
DOS 6.2 634 2720 21
Windows 3.11 634 2640 (5) 21
DOS + CDs 634 2368 24
Windows + CDs 634 2368 (5) 24
(1) Optimised using QEMM memory manager
(2) Largest executable program size. Without efficient management,
extra TSRs eat into this
(3) A well-designed program will grab as much of this as is
available in order to run faster
(4) Mostly essential to the system, and user transparent once
loaded. Some optional
(5) After exiting to DOS.
NB : if you find most of this Table difficult to follow, you will
also have problems understanding the requirements and loading
instructions of many games.

Tips to Increase Available Memory (not for the faint-hearted)
Before making any changes to autoexec.bat or config.sys save a
copy of each to a safe place (a floppy disk). Also make a system
boot disc and copy them to that. Don't forget to copy to this disk
from your boot drive a file called Doublspace.bin if you have a
compressed drive. If you hopelessly snarl up your system (it has
been known) you can then put things back to how they were.
a. "Files" and "Buffers" in config.sys should be set at 25 and 10
respectively. No need for "Stacks" or "FCBS" settings in this file
and for a stand alone machine remove the line (if present) that
begins Lastdrive=.
b. In autoexec.bat, load Smartdrive with the figure 256 as the
last parameter.
c. Use the switch /MOVE at the end of the line which loads
DoubleSpace
d. If loading DosKeys use /bufsize=1280 /INSERT
