-- 2. Introduction -----------------------------------------------------------
2.1 What is Sparcade?
Sparcade is a multi-processor emulation engine, primarily designed to
run code from the classic arcade games of the 80s.
I'd like very much to expand this section to include some detail about
Sparcade's history and my motivations for continuing with the project.
However, time is short and for now I'll have to mark it as "to be
expanded at a later date".
-- 3. Using Sparcade ---------------------------------------------------------
3.1 System requirements
3.1.1 CPU
Minimum setup
486DX2-66 with 4 megabytes of RAM
Some of the more complex titles won't run smoothly.
Typical setup
Pentium 133 with 8 megabytes of RAM
Vulcan Venture will still have problems.
Dream setup
K6-233 with 16 megabytes of RAM
Everything should run smoothly and at full speed.
Don't worry if your system doesn't meet the requirements above. Try
running a few games - you may be surprised!
N.b. Sparcade uses 486 code in some of its drivers making it
incompatible with 386-based machines.
3.1.2 Operating system
MSDOS 3.0 and above or Windows 95. Unlike the original Sparcade,
this version does not require a memory manager.
Running Sparcade from a Windows 95 DOS reboot may cause problems
if EMM386 is installed. The same appears to be true of programs
using PMODE/W, suggesting that the problem lies with the PMODE
DOS extender rather than Sparcade itself.
3.1.3 Graphics card
Basically, the faster the better. I'd certainly say users should be
aiming at VLB or PCI based cards. Does *anyone* still use ISA?
3.1.4 Sound card
Gravis Ultrasound (all models)
The GUS provides the highest quality sound for most games but
doesn't support the FM sound required by Wardner, Salamander and
Vulcan Venture.
Sound Blaster classic / pro
A Sound Blaster must have a DSP revision of 2.0 or later in order
to work with Sparcade. Unlike the GUS, the Soundblaster will work
with games which require simple FM sound. To my knowledge, no
Soundblaster in this category provides the OPL3 chip required for
Salamander and Vulcan Venture.
Sound Blaster 16 / 32 / AWE32 / AWE64
Good quality audio for all games, including those that require FM
sounds.
Sound Blaster clones
A 100% compatible Sound Blaster or Sound Blaster 16 clone should
work flawlessly with Sparcade. Cards which are not 100% compatible
may sound out of tune, especially at high mixing rates.
3.1.5 Input
Sparcade supports keyboard play or a joystick with up to 4 fire
buttons.
3.2 Installing Sparcade
3.2.1 Basic installation
Unzip Sparcade into an empty directory. If using Windows 95/98,
create a shortcut for the program 'arcade.exe' and modify its
properties as follows:
Program/Close on exit: checked
Screen/Usage: full-screen
Misc/Windows shortcut keys: all boxes unchecked
The "protected" box under "memory settings" should remain unchecked.
Owners of slow systems may find performance is increased by running
Sparcade in MSDOS mode. The shortcut can be made to do this
automatically by checking the 'MS-DOS mode' box under Program/Advanced.
Note: For correct operation with a Windows 95 keyboard, Microsoft's
"Winkey" utility should be installed. Winkey may be obtained
from Microsoft's ftp site.
3.2.2 Game ROM images
Game ROM images must be placed in individual directories. By default
Sparcade expects to find these within its own directory, however an
alternative location can be chosen (see 'the options menu' below).
The names of the ROM image directories and the files within them are
all listed in the file 'romlist.txt'.
3.3.3 Starting Sparcade
In DOS, change to the Sparcade directory and type 'arcade'. In Windows
95, click on the shortcut you created earlier.
3.3 The menu system
Use the following keys to navigate through the menu system:
up/down cursor keys - choose item
page up/page down - move rapdily through items
home - move to top item
end - move to bottom item
left/right cursor keys - change menu
return - run game or select chosen item
esc - exit from Sparcade
3.3.1 The main menu
Fairly self explanatory - select a game to play or push the left
cursor key to enter the options menu.
3.3.2 The options menu
Push the right cursor key to return to the main menu or select from
the following items:
Change monitor type
Toggle the monitor type between VGA and SVGA. Selecting VGA
allows Sparcade to work correctly on an old 640x480 monitor,
whereas SVGA will work with more modern monitors.
Why use it? Switching to SVGA mode allows Sparcade to use
higher refresh rates in some of the emulations (e.g. Pacman).
Change hires method
Select the method used to provide high resolution modes for
games such as Tron and Satan's Hollow.
Generic - Attempts to create hi-res modes using standard VGA
registers. You must calibrate your video card
before this mode will work correctly. Not all cards
provide the facilities required for generic mode, so
you may have to use "chunky" instead.
ET6000 - Turns on hi-res mode by halving the pixel width.
Surprisingly, many cards don't properly support this
feature in VGA modes. The ET6000 is one card that
does, hence the name of the option.
Chunky - If all else fails, this mode halves the horizontal
resolution and uses filtering in attempt to reduce
blockiness. Chunky mode has the added advantage of
requiring less CPU time than the other 2 modes.
Change frontend video mode
Select the type of video mode used for Sparcade's menu system.
Switch to VGA if you experience pauses when moving through menus
or, alternatively, get hold of a decent VESA implementation...!
I've only ever experienced VESA-related problems when using S3 or
ATI video cards.
VGA - 16 colour mode
VESA - 256 colour mode
VESA is used by default if it is available.
Visually, the 2 modes are identical. Later versions of Sparcade
may make more use of VESA.
Calibrate video card
This option allows Sparcade to work out which display resolutions
are available using standard VGA features. If you don't see a good(*)
spread of 'dot clock' values, you may have problems with the 'generic'
hi-res mode documented above.
(*) Typically, you will see 4 numbers ranging from 25MHz to 40MHz.
For safety, you should switch off your monitor during calibration
(switch back on a few seconds after starting calibration).
Aborting video calibration causes any previous settings to be
arranged. This feature may be used to reverse the effects of
calibration if you experience problems with your video card.
Toggle MMX optimisations
MMX optimisations may be used for future Sparcade drivers. At
present there are no drivers which would benefit from the use of
MMX code.
NOTE: This option must *not* be enabled unless your processor
supports MMX. Doing so may cause unpredictable behaviour
when running MMX-capable games.
Change ROM path
Allows you to specify the root directory where Sparcade will look
for arcade ROM images. Specifying an empty path (the default case)
causes Sparcade to look in its own directory.
Redefine keyboard controls
Modify the "global" controls used by Sparcade.
Calibrate joystick
Prepare an analogue joystick for use.
Change FM delay
Compensate for timing conflicts between newer motherboards and
old FM sound chips. The default value of 1 should work with all
Sound Blaster cards from the Pro upwards.
I'd suggest using Wardner as a test case for this option. If you
experience problems with the game's sound, increase the FM delay
and retry.
N.b. Setting the FM delay to '0' may cause early Sound Blaster
models to crash Sparcade.
3.3.3 The 'in-game' menus
The in-game menus may be accesed by pressing the "options" key
(by default, the TAB key is used).
Press ESC to exit, or select from the following items:
Game settings
Modify settings which appear as DIP switches on the original
games.
The settings will not usually take effect until the next time
you load the game.
Video settings
Slow refresh
On games with borderline performance, you may get smoother
movement after enabling slow refresh.
Frame skip
Allows display updates to be skipped in order to give faster
performance. Movement will only be smooth if a frameskip
value of 0 is used.
Scan lines
When enabled, lines of pixels alternate with black lines. Some
people seem to like this effect, though personally I find it
quite ugly.
Detail level
When set to 'low', some display features will be disabled in
order to give better performance. Currently, this option only
works with Nemesis.
N.b. The frame skip and scan lines options don't work on
Tron, Domino Man or Satan's Hollow.
Sound settings
Modify sound parameters such as volume and mixing rate.
Note that only the "master volume" setting is valid when using
a Gravis Ultrasound.
Keyboard controls
Redefine keyboard controls.
Joystick controls
Choose fire button mapping for joystick control.
Switch off game
Exit from the current game. Using this option will cause the
game to act as if it had been switched off, usually losing any
high score settings.
Return to game
As the name suggests, exits from the menu and returns to the game.
Pressing the ESC key acts as a shortcut to this option.
3.4 Default keyboard controls
The default keyboard controls for Sparcade are:
cursor keys - joystick up, down, left and right
ctrl - first fire button
alt - second fire button
space - third fire button
return - fourth fire button
TAB - enter the in-game menu system
ESC - exit from game without switching off
(play will resume from where you left it
next time the game is started)
3.5 Bench testing
New versions of Sparcade incorporate a simple benchtesting facility
which may be used to measure performance. While testing is enabled,
2 numbers are displayed: the lefthand number gives the average frame
rate and the one on the right gives the current rate. Values larger
than 9999 will be displayed in the form xxEy, where the actual frame
rate = xx * 10^y.
During test, any speed limiting within Sparcade is disabled and the
current game runs as fast as it can on your system.
Two test modes are available:
Test mode # 1
Press F10 to test.
In this mode, Sparcade emulates one frame's worth of code
from the original game, updates the display and repeats.
Once full speed for a particular game is achieved, it's
likely that your video card will become the system bottle-
neck and increasing processor speeds will have very little
impact on performance. In effect, you'll end up testing
your video card rather than Sparcade!
Test mode # 2
Press F9 to test.
In this mode, emulation of the original game code proceeds
as above but the display will not be redrawn any faster
than 60 times a second. This provides a more meaningful
benchmark than mode # 1 at high frame rates.
To disable test mode, press either F9 or F10.
-- 4. Troubleshooting and contact information --------------------------------
For troubleshooting information, refer to the on-line "frequently asked
questions" documents, accessible via the Sparcade home page. Please get in
touch via email if you have a question which is not answered there and I'll
endeavour to add it to the faq.
*Please note* - questions which can be answered by reading either this
documentation or your operating system's manual will not be answered!

Key:
S = sound support is incomplete or absent
C = some or all colours may be incorrect
G = some graphical features may not be fully emulated
SB = sound support is only available with a Sound Blaster card
PG = GUS sound support is only partially implemented
OPL3 = a Sound Blaster with an OPL3 chip is required for quality sound
(later versions of Sparcade will provide emulation for owners
of pre-OPL3 sound cards)
Additional notes:
Tron, Satan's Hollow and Domino Man
- After switching to test mode you have to exit and rerun the game.
- Game state is not saved on these games. However, high scores
and game settings are retained as on the original arcade versions.
Tron
- Tron is designed for keyboard play at present and is rather awkward with
a joystick.
Nemesis and Salamander
- Some features from one driver are not implemented in the other.
I keep meaning to get around to merging the two, using the best
parts of each.
Salamander
- Game state is not saved.
Vulcan Venture
- The driver has not been fully optimised and is unlikey to run smoothly
on anything less than a 200MHz Pentium, coupled with a fast video
card. Owners of slower systems should adjust the "frameskip" setting
in the video menu.
- On some levels, the graphics code will run out of display colours
resulting in rather odd-looking sprites.
- Using a cheap Sound Blaster clone may cause some of the music voices
to be out of tune. Keeping the mixing rate at 22KHz or below should
fix the problem.
- Game state is not saved.
