ZORKTOOLS 1.0
ZORKTOOLS is a collection of utility programs which provide capabilities not
normally available for INFOCOM games. These programs were designed to run under
any version of DOS (with one exception). ZORKTOOLS requires two drives and a
minimum of 128K bytes of FREE memory to run all the utilities. ZORKTOOLS can
handle any display type.
1. ICP - Infocom Copy Program
ICP allows you to copy any INFOCOM game disk from drive A to drive B. The
result is "standard" copy of the game which IS NOT diskcopy-able. This program
requires a minimum of 11K bytes to run. (This program does not work properly
under the latest 1.8X versions of DOS.)
If when running ICP you get the error "unknown format encountered" you will
have to run IFP (Infocom Format Program) before ICP will work successfully.
2. IFP - Infocom Format Program
IFP is program which formats a disk to 40 tracks at 8 sectors of 512 bytes.
Some Target disk you use may not be formatted by DOS. ICP & IUP require that
the Target disk be formatted to 40 x 8 x 512. This program allows you to do
that without having to leave ZORKTOOLS. This programs requires a minimum of 7K
bytes to run. WARNING!! - This program should not be used in place of DOS'
FORMAT program. IFP does NOT write a Boot Sector, FAT tables, or a Directory to
the Target disk. This program was designed, solely, as a preparation aid for
ICP & IUP.
3. IGL - Infocom Game Loader
IGL will load any INFOCOM game ("stardard" or "unprotected") from disk. Once
in memory, the game will be modified to allow it to run under DOS. When the
modification are complete, the game will be started. Once the game has booted
up it should work just as it does standalone (without DOS). To return to
ZORKTOOLS simply exit the game as always (use "quit" command). This program
requires a minimum of 128K bytes of FREE memory to run.
4. IPP - Infocom Protection Program
IPP will modify the FAT tables of an INFOCOM game disk so that the sectors
which are used by the game will be protected from DOS. (This means that you will
not be able to "erase" the game or "copy" another program on top of it.
WARNING!! - This protection scheme does not prevent "diskcopy" or "format"
from working.) Once the game has been protected from DOS you can store files on
portions of the disk not being used by the game. (Most game disk leave about
40K bytes FREE.) If you use the CATDISK Catalog Program, you can now put
.LBL files on your disk so they can be cataloged. This program requires 8K
bytes of FREE memory to run.
5. IUP - Infocom Unprotection Program
IUP allows you to copy a standard" INFOCOM ga}e disk from drive A to drive B.
Every INFOCOM game disk has tracks 1 - 3 formatted to 4 sectors of 1024 bytes
instead of the normal 8 sectors of 512 bytes. Diskcopy does not have the
ability to copy an INFOCOM game disk because of the way tracks 1 - 3 have been
formatted. When IUP writes track 1 - 3 to the Target disk in drive B it does
so at 8 sectors of 512 bytes. IUP also modifies the boot sector of the Target
disk so that the disk will boot up properly. The result is an "unprotected"
working copy of an INFOCOM game which IS diskcopy-able. This program requires
11K bytes of FREE memory to run.
If when running IUP you get the error "unknown format encountered" you will
have to run IFP (Infocom Format Program) before IUP will work successfully.
6. IVD - Infocom Vocabulary Decoder
IVD is a program which locates, reads, decodes, and displays the vocabulary of
any INFOCOM game disk. This program will produce a numbered listing of all the
words that any game will allow the player to type in (plus a few you can't).
This routine will compensate for a 40 column display. You will undoubtedly
notice that some words in the vocabulary will start with a space or have a
space imbedded in them. This is not an error in IVD. The decoding technique
used by INFOCOM leaves 6 "special" character codes which have no display-able
character defined for them. Some of the words contain some the "special"
characters. Too see where the "special" character are you must invoke ZORKTOOLS
with the /S (Special character) option. Since INFOCOM did not define
display-able character for the "special" character, the ascii values of 0 - 5
have been chosen. With the /S option the digits 0 - 5 will be displayed for the
respective "special" character instead of a space. In the vocabulary every word
has a 3 byte suffix which, I believe, tells the game the attributes of the word
(like adjective, verb, noun, etc.). To list the 3 data byte suffix you must
invoke ZORKTOOLS with the /D (Data bytes) option. This program requires a
minimum of 128K bytes of FREE memory to run.
A LITTLE HISTORY:
I have been, from the birth of PC to date, a brave and daring adventure in
realm of the Great Underground Empire, a space traveler who captures a giant
alien space craft, a detective attempting to locate a murderer, a human
computer backup who repaires an underground worldwide control complex, and a
experienced sorcerer who battles evil wizards to save the world. Through all
these truly enjoyable escapades I could not help the feeling that something was
missing. I couldn't get over the fact that a game like these require you to
have a pencil and a piece of paper (for maps, secret words, notes). Think about
it. A game made for a computer, that forces the player to use something else
to accomplish what could and should be done on the computer ! That's crazy ! I
started thinking about this problem and ways to get around it. For a long time
I couldn't think of a relatively easy way to accomplish this. Then
multi-tasking programs hit the scene. I found that the multi-tasking programs
allow the user to operate several DOS programs simultaneously. The catch is
that all of these programs must run under DOS in order to work. I then had the
task of making INFOCOM game run under DOS. That is how IGL came about. With a
multi-tasking program, it is now possible to play an INFOCOM game and have an
editor online simultaneously. That means (depending on the multi-tasking
program) that the player can usually use one key as a toggle and switch back
and forth from the game to editor. The player now has a convienent place to
store any game related data (maps, save image descriptions, secret words, etc.)
all, and this is the key, WITHOUT having their hands leave the keyboard. I
have tried this and it works great!
Happy Zorking,
