---------------------------------------------------------------------------READ THIS: COMMERCIAL GAMES, PIRACY AND ROM IMAGES
0-iii
---------------------------------------------------------------------------Despite my pleas to the public to refrain from asking me for commercial
games
(aka: ROM images), several requests daily still strangely appear in my
inbox.
Please be aware, in North America, like most areas of the world, piracy
in
any form is illegal and carries stiff penalties. To discourage piracy, I
have
made all messages requesting commercial games available to the general
public
on VSMC's WWW page, for everyone (including SPA and CAAST members, etc)
to
view.
To paraphrase: I will never send anyone a commercial game. If you ask for
one
from me, your message will appear on my WWW page. If a software
protection
agency contacts you because of this, it is your own fault -- you have
been
warned.
If you actually own the game cartridge, however, that is another
story.
Several SNES backup units exist (including do-it-yourself units), which
allow
you to copy the ROM from the cartridge into the SMC standard format. If
you
already have a backup unit, but are unable to create SMC files from it
(ie:
if you have an older MGD, perhaps), you can use any of the publicly
available
conversion/manipulation tools (such as uCON or CTOOL). Backup units,
depending upon your sociological location, may or may not be difficult to
purchase.
If you are having difficulty, use CartDisk, a home-brewn cartridge
backup
system by DiskDude of Damaged Cybernetics. Please note, however,
that
DiskDude _will_not_ supply a pre-built unit -- you must build it
yourself.
---------------------------------------------------------------------------READ THIS: SPEED CONSIDERATIONS
0-iv
---------------------------------------------------------------------------VSMC is quite possibly the fastest SNES emulator in existence. However,
you
must configure it and your system properly to achieve maximum speed.
On an
Intel 486DX2-66, 512K Internal Cache and an external bus speed of 22MHz,
the
CPU emulation speed is well over the speed of a real SNES (it was
benchmarked
at 3.83MHz ñ 5%). However, because of NMI, IRQ, I/O timing and screen
refresh
rates, the actual emulation of the SNES (CPU + everything else) will
suffer
greatly. In actual practice, a 486DX2-66 will run (best case) at about
50% of
the speed of a real SNES, and a P5-120 will run at 100% or above.
Because of
the newest optimizations present in 0.9610(d), a 486DX2-66 will sometimes
run
up to 90%, or even 100%, depending on the ROM image used.
VSMC is, by default, configured to use the true NMI rate for emulation
(of
about 50Hz, or every 53600 or 71600 internal SNES cycles). This value can
be
changed (in the form of divisions) to provide optimal performance. NOTE:
The
SNES is a time-sensitive machine, and many games will stop functioning if
the
NMI rate is thrown out of balance. It is also possible to slow down a
game
considerably, or cause a game to lock at seemingly random points within
game
play. There is no 'fast' or 'slow' end of the NMI scale, the fastest
setting
will likely (always) fall in the middle, and the slower settings will
extend
outwards. See 'IRQ and Refresh Rates' for more information.
Something to try: Run Super Mario World with the IRQ at '4'. Then run
it
again at '2' -- notice the great speed increase. Set it to '0' and watch
SMW
grind to a halt.
The refresh rate controls how often the screen is updated based
NMI
on
the
blanking rate. Higher settings will result in fewer screen updates per
NMI
(as few as 1 refresh per 9 NMI interrupts) thus faster emulation speed
but
jerkier movements (suitable for RPG games). Lower settings will result
in
more screen updates per NMI (up to a maximum of 1 refresh per NMI), thus
you
will observe slower emulation speed but more fluid movement (suitable
for
action games). See 'IRQ and Refresh Rates' for more information.
The joystick option of VSMC will also slow down emulation somewhat (but
not
noticibly on most machines). If the speed seems overly slow, disable
VSMC's
joystick option.
EMS, Virtual Screen and Tweaked VGA mode should be enabled. EMS uses a
2MB
demand page buffer for bank storage. Note
that EMS, in this
case,
requires less processing than XMS, since the SNES, utilizing the 65816,
uses
a banked memory system where only two banks of 32K are available at one
time.
Coincidentally, this also happens to be the same size as an EMS
window.
The Virtual Screen option stores and processes all video data in
memory
before sending the entire stream to the real video RAM all at once.
This
generally results in greatly improved performance. Tweaked VGA mode is
faster
than generic 320x200 because no multiplications or shifts need to take
place
when calculating screen offsets (though, only one such calculation is
used
for each BG plane.)
To further enhance performance, consider: Tweaking your external bus
speed,
overclocking your CPU, upgrading your EMS manager, & running it from true
DOS
(not a Win 95, OS/2, WinNT, etc. DOS box).

---------------------------------------------------------------------------READ THIS: FREQUENTLY ASKED QUESTIONS
0-vii
---------------------------------------------------------------------------[*] Why is VSMC so slow on my system?
See section [0-iv] of VSMC.DOC. Most solutions to common problems
are
solved here.
[*] Could you work on getting <name_of_game> to work?
No. I will not entertain requests from people to get a specific
game
to work. If you'd like to take the initiative and debug a ROM
image
yourself, then by all means tell me what specific bugs VSMC has,
and
I'll gladly correct them.
[*] Could you send me a copy of <name_of_game>?
NO! For the last time, NO. See section [0-i]
the
consequences.
of
VSMC.DOC
for
[*] How do I get files with the extension .SFC to run on VSMC?
Most newcomers to the SNES scene do not realize that .SFC files are
structurally the same as SMC files. Just rename them from DOS.
[*] How do I get files to work if they use a raw or interleaved format?
Use CTOOL, uCON, CCX, STOOL or any other image conversion utility.
[*] How do I get an SRAM file from my copier to work correctly with VSMC?
Most copiers use VSMC-compatible SRAM files, so you only need to
copy
the file into VSMC's directory with the SMC file's name and the
'SRM'
extension (ie: SMW.SMC should have an SMW.SRM file). Some
copiers,
however, do not create VSMC-compatible SRAM files, requiring that
you
use a program capable of converting SRAM files (such as CTOOL).
[*] Why doesn't <name_of_game> work with VSMC?
I don't know. If I knew, I'd have fixed the problem and you
wouldn't
be asking.
[*] When will VSMC support <new_feature>?
I don't know. When it does, you'll know.
[*] When's the next release?
There are always at least three releases every month. If
that's
not
good enough for you, you've got some serious problems and should
seek
professional help.

---------------------------------------------------------------------------VSMC SETTINGS: DEFINING THE KEYBOARD
3-i
---------------------------------------------------------------------------The keyboard is used to emulate Joypads 1 thru 4 of the SNES. To define
the
keys to use, click 'Define Keys' from the main menu in VSMC96.EXE.
A (sort of) diagram of the SNES joypad will appear. Click a button on
the
joypad to define, then, when prompted, press the key to use. Repeat
the
process for each button on the joypad. (These settings are saved in the
EXE
file, so there is no need to redefine the keys the next time you start
VSMC).
Some people have experienced difficulty when defining their keys. If
the
prompt to select the key appears, then immediately disappears without
giving
you the opportunity to actually select the key, do the following:
- Hold down the key you want to use, until the keyboard buffer fills
and
the computer begins to produce the buffer-full beeping noise.
- Click the joypad button you wish to assign the key to.
I have not tried this, personally (I don't have this problem), but I've
heard
that it works.
0.9611(a) should fix this problem.
---------------------------------------------------------------------------VSMC SETTINGS: OPTIONS
3-ii
---------------------------------------------------------------------------VSMC options can be changed by clicking 'Emulation Options'
main
menu of VSMC96.EXE.
from
the
- VIRTUAL SCREEN Purpose: Buffers the data from the PPU emulator and sends it out to
the
VGA card all at once, as opposed to using the VGA card's
RAM
as the PPU workspace.
Advantages: Greatly reduces flicker and greatly increases speed.
Side-effect: Requires an additional 64K of conventional memory.
- TWEAK Purpose: Enables VGA MODE-Q, a tweaked VGA mode.
Advantages: Allows you to see the entire SNES screen without any
missing
vertical lines. Improves graphics speed (somewhat).
Side-effect: Does not work with some 'intelligent' monitors.
- JOYSTICK Purpose: Allows you to use a standard IBM-PC joystick with VSMC.
Advantages: Obvious.
Side-effect: Slows down emulation on some computers.
- AUTO-DEBUG Purpose: Enters the debugger immediately upon selecting an SMC file.
Advantages: Suitable for programs which lock up near the beginning of
execution, or for serious programmers.
Side-effect: Unknowegable users find this intimidating.
- USE EMS Purpose: Creates a 2MB demand-page buffer for ROM banks.
Advantages: Greatly improves VSMC's emulation speed, reduces wear on
hard
drive (as if anyone cares)
Side-effect: Requires 2MB of additional memory and an EMS manager.
(note: EMS, with regards to 65816 emulation, is faster than
XMS, because only one segment needs to be used at any time.
This segment register can be held constant all times, rather
than swapping it, as is the case with XMS, during a data bank
or program bank change on the 65816 side. So don't complain.)
---------------------------------------------------------------------------VSMC SETTINGS: IRQ AND REFRESH RATES
3-iii
---------------------------------------------------------------------------These options can be changed by clicking 'Emulation Options'
main
menu of VSMC96.EXE.
from
the
- IRQ The IRQ rate (actually the VBlank NMI) is depicted on a scale of values
from
zero thru nine. Each unit represents a 13400 cycle wait-state between
NMI
interrupts. A setting of '3' (the default) will result in a 53600 cycle
wait
between NMI (resulting in a 50Hz NMI). All values for this option are
listed
here:

Default
(The NMI Speed and NMI Period above assumes slow-rom operation. Neither
NMI
period nor NMI speed are the 'real- life' values. They are values
used
internally by the emulator to ensure proper timing based on cycle
counts.)
NOTE! In 0.9610(d), the implementation of NMI has changed. Although a
value
of '3' will still result in a 52K-u wait state, it will actually
perform
269, 205-u waits (one for each hblank, including overscan). This has
been
done to provide VSMC with proper vblank and hblank IRQ timings, not
just
proper vblank NMI timings. Therefore, although each unit on VSMC's IRQ
timing scale still represents a 13400-u wait state for NMI interrupts, it
is
now actually implemented as a 51-u wait state between hblank IRQs.
- REFRESH RATE The refresh rate tells how many NMIs to wait before refreshing
screen,
the
if it is deemed necessary. See 'speed considerations' for
implications
of this option. '1' is usually selected by default.

Actual

view
using cycle counting. As Viewed indicates the rate of refresh that the
enduser would likely see, if (s)he was using the 'Suggested System' of a
486DX2
66MHz. This value would greatly fluctuate, however, depending on the
load
caused by multiple BG planes or a high number of bitplanes in each BG
plane.
Actual Rate would not fluctuate, as it is not affected by factors
'external'
to the actual emulation aspect of the program.)
---------------------------------------------------------------------------RUNTIME FUNCTIONS: THE CHEAT FINDER
4-i
---------------------------------------------------------------------------Yes, now even _you_ can finish Actraiser.
The operation of the cheat finder is simple. You tell it what value to
look
for in memory. You then change this value somehow (perhaps you die,
causing
your lives-in-reserve to decrease). You then search for this new value.
Once
the cheat finder narrows the possibilities down to one or two, it will
give
you the memory address of whatever you were looking for (your lives, in
this
simple example). You can then freeze this address at whatever value
you
want. The cheat finder is activated from the debugger (F1) while playing
the
game.
A real example:
Start up 'Actraiser(tm)' on VSMC and enter an action scene.
Count the number of health bars (the blue things at the top) you have.
Enter the debugger (hit F1), then select the cheat finder (hit F5).
Select 'New Search'.
Select 'Continue Search', and enter the number of blue health bars you
had.
Return to the game (F10).
Get hit by something, and re-count the number of blue health bars you
have.
Enter the debugger (hit F1), the cheat finder will already be selected.
Select 'Continue Search', and enter the number of blue health bars you
have.
You should now see only one or two matches. One will have the address
'29'
associated with it. This is your hero's life. Select one of the freeze
slots
(slot '1', for example), enter this address ('29'). Enter the amount of
life
you want (try '30'). Because this is 'frozen', you life will _always_
remain
at '30'. Go back to the game with 'F10', and have fun.
Note: Realtime save can also be used as a game-cheat utility. Simply
save
the state as you progress through the game. If you are defeated, or take
a
wrong turn, load the saved state. Press 'F4' during gameplay for
list
of keys used in association with the realtime save functions.
