Frequently Asked Questions About:
Professor Street Fighter 2
by: AkumaX (IRC)

--------------------------------------------------------------------------
Preface:
The purpose of this FAQ is to answer questions about the
Professor Street Fighter 2 (Also known as the Multi Game Doctor 7).
From here to the rest of the FAQ, I will refer to the Professor/Game
Doctor as PSF2. The FAQ will help non-owners to understand what the
unit is, and will help people who own the PSF2 convert their games
successfully. The FAQ is a compilation of knowledge that I have
acquired through trial and error, and with the help of other owners
of the PSF2. The goal is to help users successfully convert almost
any game they come across and gain a general understanding of the unit.
However, I would like to add that if you especially like a game,
please go out and buy it. The prices on SNES games are extremely low
at present and some of the true masterpieces are worth the money for
the moral implications of owning a game you enjoy. So if you plan to
play it often and essentially get your money's worth out of it, then
put your money into it. Thanks.

--------------------------------------------------------------------------
I. What is the PSF2?

The PSF2 is a console copying unit for the Super Nintendo (SNES).
The unit plugs in where you would normally put a cartridge. It has a
power connection, a parallel port connection, a 3.5 disk slot and a
cartridge slot. There is also a slot on the bottom where extra memory
can be installed. Normally the PSF2 comes with 32 megabits of memory.
Megabits are one-eighth of a megabyte. To convert from megabits to
megabytes, you divide bits by 8. So 32 megabits / 8 = 4 Megabytes of
memory. PSF2's can go up to 64 and even 128 megabits of memory for
holding more games in memory.

The power connection: Where you plug it into the wall...:)

Parallel connection: The PSF2 comes with a utility that
is also available on the net called TSF3. It allows
you to copy games via your parallel port into (or from)
your copier.

Cartridge slot: You can use the cartridge slot to play
cartridge games and back them up to disk.

Disk Drive: You can use the disk drive to load/save
ROM images of cartridges into the PSF2's memory.

In addition to copying and playing games, the PSF2 also has a
Super Mode and a GoldFinger ability.

Super Mode: Running a game in Super Mode allows the player
to play games at half speed, quarter speed, and save and
load games at any point in any game.

GoldFinger: This is similar to Game Genie. There is a utility
that converts Game Genie codes to GoldFinger codes.

--------------------------------------------------------------------------
II. PSF2 Filenames.

The PSF2 is fairly lenient on it's filenames. However, there
are some restrictions you must follow in order to properly load games.
The filename consists of 8 letters, divided as follows:

The first two letters must ALWAYS be "SF". The unit will NOT
read files that do not begin with these letters.


The next parameter is optional. You can specify the size of
a game with a number. The number is in megabits and is used
to override the PSF2 if it guesses a game's size incorrectly.

Example: Final Fantasy 5 is a 16 megabit game. However,
when you apply the English patch, it grows to 20 megabit.
If you try to load the game without specifying the 20
megabit, it will stop at 16. So the filename should
start with "SF20".


The next parameter is open; you can specify 3 characters
of anything you want. When the PSF2 copies files, it
uses the space for the catalog number. If you omitted
the previous filesize parameter, this field can be 5
spaces long.

The eighth character in a filename is ONLY used for files
that are split. If you have an image greater than 8
megabits, then you will more than likely need to split the
files. More on splitting later, but in order for the PSF2
to know you have a split file, the last character is specified
as "A", "B", etc. If the game is only one file, then you can
leave this field blank.


Examples:
SF10123A -> First file of a 10Mbit game with the
name "123".

SFCLIFF -> Game with a name called "CLIFF". This
is the only file and the file size has
been omitted.

It's also been noted by other users that when the PSF2 makes
a copy of a "HiRom" file (More on HiRom vs. LoRom later), the 7th
character is specified as an "X." I don't know if naming a file with
an "X" in it specifies to the unit that the file is HiRom, but I've
never had to do it in order to get a game to work. Still, it's open
to consideration and something to try if you're stuck.
--------------------------------------------------------------------------
III. Basic utilities

The following are basic utilities you will use when you
manipulate your ROM images.

UCON: If you can only have one utility at your disposal, you
MUST use UCON. UCON is the most useful tool you will
find for SNES. It doesn't do EVERYTHING that you will
need, but it applies IPS patches, gives you information
about a ROM, splits, joins, converts, etc. Get UCON.

SNES Tool: SNES Tool is not as useful as UCON, but it has
features that UCON does not. SNES Tool can
attempt to remove trainers and splits HiRom
files differently than UCON. If UCON is not
correcting a problem for you, SNES Tool is
probably the next place to go.

Kill 'Em: Kill 'em is a copy protection tool. It patches 
NTSC and PAL codes, and SlowRom codes as well. 
More on these later, but even though some of
these codes are covered in UCON and SNES Tool,
there are many different types of these codes.
You will find that some utilities find codes
that other utilities do not. Kill 'em is
used specifically for removing these codes. In
general, I find that it's found more than UCON
and SNES Tool do.

Multi Tool: Multi-Tool is a tool like UCON and SNESTOOL, but
I find it most useful for removing even more
PAL/NTSC and SlowRom codes.

STOOL: STOOL is a utility that you will not use often.
It's most useful for converting 24Mbit images,
since you can use it to split into 3 8Mbit files.

SAVEFIX.IPS: This IPS patch is helpful if you have a ROM that
has SaveRAM, and you find you cannot save your
game. This mostly occurs in games that are 32Mbit
and have SaveRAM. However, there are some 24Mbit
games that need it as well. The English FF5 and
Breath of Fire 2 are examples. Use UCON to apply
the patch to the first PSF2 file after you've
converted and split the files.

FDREAD: Your PSF2 can format a disk to 1660k as opposed
to the PC's 1440k. This is useful for running
12Mbit games all on one disk. FDREAD allows
your PC to read these disks.

COMP: Compares two files and outputs differences. Useful
to see if you have two copies of something. If you
are trying to get a game to work and it doesn't,
you try something else and if the file size is the
same, compare the two to see if you're not covering
ground you've already covered.

FILECUT: This cuts out pieces of a file that can be useful.
In some games there is a 512 byte header that you
might have to remove in some cases. FILECUT is
great for doing these things.

There are a couple more utilities that people recommend and use,
but the above are what I've found the most useful. I will refer to these
utilities when I discuss working with different files.
--------------------------------------------------------------------------
IV. Loading Files

There are a few things to remember when loading a file. This
section assumes that you have a ROM in PSF2 format. Plain ROMs load
normally. If they are above 8MBits/per disk, the PSF2 will split the
ROM in it's memory. If the ROM is split across multiple disks, it will
ask for the next disk. If you have a 24MBit game split into 2 12Mbit
files on two disks, they will take up 3 slots of PSF2 memory. If your
game has Save RAM, be SURE to load your BRAM file into memory and SAVE
your BRAM file when you're done. If that game ever leaves memory, or
another game that uses BRAM is loaded, your BRAM file is gone. I always
save my BRAM to disk when I'm done playing as a precaution. BRAM files
are the same filename as the game, with the extension .B0X where X is
1,2,3, etc. The PSF2 gives you the option of changing the "X" to suit
multiple BRAM files. Some games need to be loaded in a specific slot to
work right. I imagine it has something to do with memory addressing.
I've only seen this problem once, but for your information, here it is:

Lufia I: Playing the game is error-free until the very end of the game
where you acquire an airship. The game would freeze every
time I landed the ship. However, loading the game in the
"A" slot of the PSF2 solved the problem. I've never seen
anything like it again, but if you encounter the problem
of freezing midgame in any game, the slot might be worth
changing.

Saver files, made in Super Mode, can be loaded and saved in
the same fashion as BRAM files.
--------------------------------------------------------------------------
V. Converting Files

This is the only part of PSF2 manipulation that is not straight-
forward. It's either a painless, error-free process, or it requires a
bit of messing around. I will provide a general overview and some tips
for troubleshooting, but bear with me and keep in mind that there is no
single way to make ALL ROMs work. The way to find out pertinent
information about any ROM is to use UCON. UCON <filename> will provide
you with what you need to know in order to use this section. It should
be noted that GD3 and MGD2 are valid formats for the PSF2.

8Mbit filesize:

LoROM: There should be no conversion necessary. Rename the file to
SFXXXXX and it should run as normal.

HiROM: Same as LoROM. If the game fails to run correctly, use either
UCON's "F" option or SNES Tool's "Fig -> GD3" option. This
will split the HiROM into 2 4Mbit files. This is sometimes
necessary due to the mapping procedure of HiROM files. Another
thing to check with HiROM files is the file size. If it's
1048576, then it is exactly 1Mbit. If the file size is
1049088, then it has a 512 byte header. The PSF2 accepts
either, but if you encounter problems, you will want to:
A: Remove the header with FILECUT.
You can try the game this way or:
B: Add a 512 byte header from another 8Mbit game that
you are positive works. This is done using the
binary paramter with copy:
"copy /b HEADERNAME + ROMNAME /B OUTFILE /B
Where HEADERNAME is the name of the 512 byte header
file, ROMNAME is the name of your ROM and OUTFILE
is your finished product. This manipulation of
the 512 byte header is a good thing to check on
ALL HiROM games that do not work.

12Mbit File Size

LoROM: If you format a disk with the PSF2 to 1660k, you can
copy the game directly to your PSF2. Just be sure
to rename it to a valid filename. Otherwise, you
can split it with UCON.

HiROM: Use SNES Tool to split the ROM into the proper sections
for a HiROM. This (and UCON's "F" option) usually 
results in a 8Mbit and a 4Mbit file.

16MBit File Size

LoROM: Use UCON's "C" or "F" parameter to convert from either ProFighter
or Super Magicom format to MGD2. Then use the "S" paramter to
split them.

HiROM: Use SNES Tool to convert the ROM or UCON's "F" option. It
should split the ROM into two 8Mbit files. See the 8Mbit
section on headers if you still encounter problems.

20MBit File Size

LoROM: Use UCON's "F /3" to make 3 8Mbit files. This comes out
to 24Mbits. An alternative is to split the file into 2
10Mbit files using the "S" option. Some games don't
like this split, but most have little trouble.

HiROM: Use UCON's "F /3" or SNES Tool's "Fig -> GD3". Check
header information in the 8Mbit section if problems
persist.

24MBit File Size

LoROM: You can use the PSF2 to format 2 disks to 1660k and split the
image into 12Mbit sections. Or use STOOL -s? to split into
3 8Mbit files.

HiROM: Use UCON's "F" or SNES Tool to split. I recommend 3 8Mbit
files for HiROM because HiROM seems to be more cooperative
the more you split. Check the 8Mbit section for header
information.

32Mbit File Size

These are usually HiROM so use the "F" option in UCON or SNES
Tool to convert to 4 8Mbit files.

A good indicator that your ROM has loaded correctly in your
PSF2 is the ROM name appearing in the space next to the slot on your
unit. If the file still refuses to run:

Try the SlowROM fix, found in UCON, SNES Tool, MULTI71, and KILLEM.
If it modifies your ROM, you've fixed any SlowROM problems with your
ROM. Try loading it again. Another fix to try, found in the above
utilities is NTSC/PAL fixing. This fixes problems with overseas
games. It also solves the "This game was not meant to be played on
this system." message you sometimes receive. The last thing to try
is cracking the game. Use the "k" option in UCON. If the game
still causes trouble, it's most likely HiROM. Try to append and
remove headers, try different splitting routines, or ask someone
who has gotten it to work.

If the filesize is an ODD file size, that is NOT an even Megabit,
then it has an intro or a trainer. Use SNES Tool to try and remove
it if you don't want it there. Otherwise, use UCON's "p" option to
pad the image to the nearest Megabit.

If the file has BRAM and will not save, use UCON's "i" option to
apply SAVEFIX.IPS to the first file of your ROM (SFXXXXXA).

--------------------------------------------------------------------------
VI. Games that won't run on a PSF2.

This is a quick list off the top of my head that is NOT complete.
There are games with special hardware (DSP, FX, Capcom Compression) that
will not work with the PSF2. I've heard that DSP games will run with
a DSP game in the cartridge slot, but I've never gotten it to work myself.
Anyways, here are the games:

DSP: Pilotwings, Mario Kart, ?Super Mario RPG?, ?Kirby Superstar?
FX: StarFox, Doom, Yoshi's Island
Capcom: MegaMan X2, MegaMan X3, Street Fighter Alpha 2.

These are the games I see asked for most frequently on the channel. The
ROMs are out there, but useless for copier or emulator purposes.
--------------------------------------------------------------------------
VII. Other notes

The PSF2 is a high interference machine. When it's plugged
into your SNES and has power running to it, it will cause major
interference with your TV. This isn't a faulty unit. Just keep
your SNES about 5-10 feet from your TV. I've been told that using
the AV cables as opposed to the coax RF switch reduces some of the
interference, but I've haven't been able to confirm it. (Old TV).
Radio Shack also sells interference surpressors, but I haven't tried
those either. Still, it's not a defect with your unit, just the
way it is.
--------------------------------------------------------------------------
VIII. Conclusion

Well, that's about the whole of it. You will find the most
trouble converting games, and it just takes practice and assistance.
Eventually, you'll work out a system that works for you and be able
to run most games successfully.
