This is for people who want to know what the various sections of a pet file
|
||
|
|
contain. The structure is very similar for a baby file. I'm just going to
|
||
|
|
show this as links to a series of screengrabs, as I don't have time to do
|
||
|
|
anything fancy with it. Pet and baby files are in fact saved-game files, so
|
||
|
|
their internal information is changing all the time. However, the basic
|
||
|
|
structure remains the same throughout, so we can do a fair bit of analytical
|
||
|
|
work just looking at a pet or babyz in a hex editor. I'm not including any
|
||
|
|
breakdown of Petz II .pet files, as they are very different.</p>
|
||
|
|
|
||
|
|
<p><a href="PetNameIDAndBreedfileSection.gif">Here is the start of a typical
|
||
|
|
Pet adopted in Petz 3, 4 or 5.</a><br>
|
||
|
|
In it you can see the pet ID up there in the first two bytes, before the
|
||
|
|
name Rosie. This is the section containing the petname, ID and main
|
||
|
|
breedfile name. In a pet which has been imported from PetzII there is a
|
||
|
|
bunch of other stuff in there too, but it's not really important.</p>
|
||
|
|
|
||
|
|
<p><a href="xChecksumSection.gif">This is the end of the first
|
||
|
|
section.</a><br>
|
||
|
|
The part which you see highlighted is where the checksum information
|
||
|
|
resides.</p>
|
||
|
|
|
||
|
|
<p><a href="bStartofSectionContainingSliders.gif">This is the start of the
|
||
|
|
section which contains brainslider data etc</a><br>
|
||
|
|
note for those who want to cheat -- this section is where you should find
|
||
|
|
the things that your pet learns, its tricks abilities etc.</p>
|
||
|
|
|
||
|
|
<p><a href="aBrainsliderdata.gif">here's where the actual slider data is
|
||
|
|
kept</a><br>
|
||
|
|
The highlighted section shows where these important bytes are stored. I show
|
||
|
|
how to deal with these in one of my tutorials.</p>
|
||
|
|
|
||
|
|
<p><a href="EndOfSectionContainingSliders.gif">This is the end of the
|
||
|
|
section containing sliders.</a></p>
|
||
|
|
|
||
|
|
<p>And immediately after that:</p>
|
||
|
|
|
||
|
|
<p><a href="StartOfPaintedBallzSection.gif">this is the section with your
|
||
|
|
pet's colour data</a><br>
|
||
|
|
This is where the game stores whatever paint you throw at your pet from the
|
||
|
|
can; if you don't paint the pet, it stores the pet's default colours here.
|
||
|
|
It's the reason why, when you change certain ball colours in the .lnz
|
||
|
|
section, you have to say "restore original colours" within the game before
|
||
|
|
you see them. It's also why babyz' hexed eyelids don't show up as altered;
|
||
|
|
there is no "restore" in babyz because there's no paint pot. But of course
|
||
|
|
you can edit the relevant byte in this section, as I show in a "howto"
|
||
|
|
elsewhere.</p>
|
||
|
|
|
||
|
|
<p><a href="EndOfPaintedballzStartOfLnzSection.gif">The start of the .LNZ
|
||
|
|
sections</a><br>
|
||
|
|
Where the shape, default colours etc of the pet are defined. It comes in two
|
||
|
|
chunks, the first of which is the adult data and the second of which is the
|
||
|
|
puppy or kitten data. As of 2005, you can now edit these directly in
|
||
|
|
Nicholas' LNZPro utility of course.</p>
|
||
|
|
|
||
|
|
<p><a href="EndOfLnzSectionStartOfClothingNBreedInfo.gif">The end of the LNZ
|

|
||
|
|
|
||
|
|
<p><a href="StartOfClothesAndBreedzInfo.gif">The clothes and breedfiles
|
||
|
|
section</a><br>
|
||
|
|
This section directly after the lnz info is where you'll see listed any
|
||
|
|
clothing items that your pet is wearing. No need to edit this, just take the
|
||
|
|
clothes off your pet or baby in the game! If there is a problem with
|
||
|
|
starting the game because the clothing item is missing or damaged, just
|
||
|
|
re-set your game as you start it up by hitting Ctrl and Shift together.</p>
|
||
|
|
|
||
|
|
<p><a href="zEndOfClothesAndBreedzInfo.gif">End of clothes and breedfiles
|
||
|
|
section</a><br>
|
||
|
|
As you can see, the breedfiles which the pet needs are listed here, usually
|
||
|
|
with their ID numbers.<br>
|
||
|
|
<a href="EndOfClothesAndBreedzInfo.gif">Here's another pet's similar
|
||
|
|
section</a><br>
|
||
|
|
so that you can see how it's done a bit clearer.</p>
|
||
|
|
|
||
|
|
<p><a href="aGenderNeuterdetailsAndStartOfBreedIDstuff.gif">This section
|
||
|
|
contains gender and main breed ID info</a><br>
|
||
|
|
Here's the section that you need to concentrate on if you're changing a
|
||
|
|
petfile's gender, or if you're trying to make it accept a different breed
|
||
|
|
ID.</p>
|
||
|
|
|
||
|
|
<p><a href="GenderAndNeuterSection.gif">The gender and neutering
|
||
|
|
section</a><br>
|
||
|
|
The highlighted bytes are where you change gender or neuter and un-neuter
|
||
|
|
your pet. I show how to deal with this in one of my tutorials. Of course as
|
||
|
|
of 2005, you can alter the gender using Nicholas' Petza utility.</p>
|
||
|
|
|
||
|
|
<p>Also in this section of a pet, after YALP and before the breed ID info,
|
||
|
|
you'll see an area which varies in length as your pet's experiences in life
|
||
|
|
occur -- experiences such as finding a mate and so on.</p>
|
||
|
|
|
||
|
|
<p><a href="BitWithBreedIDInfo.gif">The breed ID info</a><br>
|
||
|
|
The highlighted bytes show where you would find the main breed ID number
|
||
|
|
that your pet needs. I show how to deal with this in my tutorials.</p>
|
||
|
|
|
||
|
|
<p><a href="EndOfYALPsectionStartOfGeneticsSection.gif">End of YALP section,
|
||
|
|
start of Genetics</a><br>
|
||
|
|
This is where an important part of your pet resides -- its genetics. I show
|
||
|
|
in howtos elsewhere how to find and alter some of the important genetic
|
||
|
|
bytes such as the Alley Sickness etc. You can now change these of course in
|
||
|
|
Nicholas' LNZPro utility, but there's still plenty to explore here :-)</p>

<p><a href="FamilyTreeDateofBirth.gif">Date of birth in Family Tree</a><br>

The highlighted bytes are where the date of birth resides. I show how to

|
deal with this in one of my tutorials.</p>
|

|
|
|
||
|
|
<p><a href="FamilyTreeNumberOfGenerations.gif">Number of generations for
|
||
|
|
pet</a><br>
|
||
|
|
The byte which you see highlighted is the number of generations, in
|
||
|
|
hexadecimal of course.</p>
|
||
|
|
|
||
|
|
<p><a href="FamilyTreePinkoutlineorblue.gif">The pink or blue outline in
|

The part which you see highlighted is where the pink or blue byte is stored.

|
|
I show how to deal with this in one of my tutorials.</p>

|
|
<p><a href="InPregnantPetEndOfFamilyTreeStartOfBabyData.gif">End of family
|
||
|
|
tree section.</a><br>
|
||
|
|
This particular pet is pregnant, so what you see here is also the start of a
|
||
|
|
pup's data.</p>
|
||
|
|
|
||
|
|
<p><a href="StartOfBaby.gif">The start of the puppy's file.</a><br>
|
||
|
|
Here is the start of the puppy's data. The structure of the puppy file is
|
||
|
|
the same as that of the mother, but it doesn't have the initial loading
|
||
|
|
section with the pet ID and name because of course the game doesn't need
|
||
|
|
that until the pup becomes separated from the mother. If there is more than
|
||
|
|
one pup (or of course kitten for a catz pet), each pup or kitten's data
|
||
|
|
follows the other after the previous one's family tree data.</p>
|
||
|
|
|
||
|
|
<p><a href="StartOfBitmap.gif">Start of bitmap</a><br>
|
||
|
|
And this is the end of the petfile, the bitmap which you see when the pet
|
||
|
|
comes out of the door. This is not included in the checksum, so if this part
|
||
|
|
only is corrupted you can simply replace it with another bmp file in order
|
||
|
|
to get the game to accept the pet or baby. I show how to do this in one of
|
||
|
|
my tutorials.</p>
