1. Introduction

09/03/02 Righty then.  To all who have taken the time to look at this 
guide, i'd like to thank you.  This is my very first work for any game 
anywhere, so when you decide to comment / flame me, be nice please.  How 
you respond to this work determines whether or not i do any more work in 
the future.

Ok now we've got the 'be nice to me' bit out of the way, to make this
guide, i used the TGB Dual GBC emulator and my trusty copy of 
Hex Workshop.  I use these because i think that they are the best out 
there and where the others fail, these succeed.
The latest versions can be downloaded from :-

11/04/02 I kind of lost interest in this guide, and i kind of lost the 
guide i keep on my computer because of a reinstallation of windows.  
Most of the new stuff in here is all because of Crescens 2k.  He and 
certain e-mails i've recieved have given me back my inspiration to write 
this guide again, so a big thank you to all involved ^_^
2. Legal Stuff

This Guide was typed by ME! I put a lot of work into this.  Discoveries
were made by ME unless stated otherwise.  Anyone's work i use, i credit
them in the Credits section of this guide and in the place in the guide
where i use their work.  Please do not plagarize my work or do anything
with this guide other than its intended use because i won't be happy
and neither would you be if it happened to you.  Remember that the 
Hentai Fairies know where you live!

There will be a list of sites with permission to post this guide here

3. The Guide

Before i begin on the bit you've all been waiting the last 2 sections
and table of contents for, i need to explain a couple of things.
The harvest moon 3 save states gives you the full save file so you are
therefore able to modify things in both save games, and also the active
game data is also stored in a second memory location.  The offset 
(difference) between game 1 and game 2 is 1000 hex.
Put into english it means that since the game 1 main character name is 
stored at 00012008 - 0001200B then the main character name for game 2
is stored at 00013008 - 0001300B.  If you compare the two, then you 
will see that there is 1000 hex difference between the two addresses.
Also, assuming that game 1 is the active game, the main character's
name will also be stored at 00001404 - 00001407.  The rule is the same
for all the data discussed in this guide, only the addresses are 

3.1 Character/Partner Names

Main Character

Active Data - 00001404 - 00001408
Game 1 Data - 00012008 - 0001200B
Game 2 Data - 00013008 - 0001300B


Active Data - 00001414 - 00001418
Game 1 Data - 00012018 - 0001201B
Game 2 Data - 00013018 - 0001301B

3.2 Animal Names

The rule for all the animals you can give names to (cows, horses, 
sheep) is that starting from the start value, you can put in 8 names
of 4 letters but you have to put in FF after each name.  You must also
use FF to signify a blank if your animal's name has less than 4 letters
(eg. a cow named moo or a sheep named baa)

Example 1, a cow named Beef
the value would be 0B (B) 28 (e) 28 (e) 29 (f) and you would put FF 
after this so it would read in your hex editor 0B282829FF

Example 2, a sheep named Baa
the value would be 0B (B) 24 (a) 24 (a) FF (blank space) and you would
put FF after this so it would read 0B2424FFFF in your hex editor

After the FF that indicates the end of the name, you can put in the
value of the first letter of the next animal's name


Active Data - Starting from 0000172A
Game 1 Data - Starting from 0001232E
Game 2 Data - Starting from 0001332E


Active Data - Starting from 00001752
Game 1 Data - Starting from 00012356
Game 2 Data - Starting from 00013356


Active Data - Starting from 0000177A
Game 1 Data - Starting from 0001237E
Game 2 Data - Starting from 0001337E

3.3 Partner's Love

This bit nearly didn't happen, it was the hardest to find in the save
state file.  it was thanks to ragewarrior's code that this value was

this one hasn't been completely tested yet so i'm not sure if it allows
you to marry them after a while.  when you do set the max value though
the partner does speak about making the girl's father's dream come true
so i can only assume that if you keep giving her items, the marriage
will eventually happen.

The MAX value for the partner's love is 63 Hex.  if you go higher than
63, the game will put your partner's love back to 0
If anyone finds out if you can marry the partner, or if any of my 
assumptions here are incorrect, please let me know

Also note there are two values for love. Both of these need to be maxed
for the game to start on the marrage. If you don't max both of them
then you will have to wait while the game brings up one of them by
you giving an item a day.

Active Data - 00001A35 and 00001A36
Game 1 Data - 00012639 and 0001263A
Game 2 Data - 00013639 and 0001363A

3.4 Friends

Here I will give you the addresses for the other people in the game.
Remember though that not all of the general people have friendship
values, only the ones in this list. I may be missing one, so please if
anyone knows could you tell me.
As with the other sections, the max value for friends is 63 Hex.

3.5 Animal Condition / Affection / Gender / Age / Colour

Maxing a chicken's affection rating WILL turn the chicken into a GOLD
With the other animals, maxing their affection will be the same as if
the girl partner had been taking care of them for all that time,
i.e large milk, and the best wool.

max affection ratings for the animals is 63

Affection Ratings

These are 8 bytes one after another for each animal. 17A2 is sheep 1, 
17A3 is sheep 2 etc.


Active Data - starting from 000017A2
Game 1 Data - Starting from 000123A6
Game 2 Data - Starting from 000133A6


Active Data - Starting from 000017AA
Game 1 Data - Starting from 000123AE
Game 2 Data - Starting from 000133AE


Active Data - Starting from 000017B2
Game 1 Data - Starting from 000123B6
Game 2 Data - Starting from 000133B6


Active Data - Starting from 000017BA
Game 1 Data - Starting from 000123BE
Game 2 Data - Starting from 000133BE

Condition/Gender etc.

Each of these are 5 bytes long, and there is one for each animal. 
Sheep 1 is at 168A, sheep 2 is at 178F etc. The layout of the 5 
byte blocks is as follows. Byte 1 is if you have one and it's
gender, value between 80 and BF will mean you have one and it's 
male, a value between C0 and FF will mean you have one and it's 
female. Byte 2 is for the growth of the animal, if it is young or
adult. Byte 3 is for the colour of the animal in general. Byte 4 
is for the condition of the animal, 00 is healthy, 01 is Unhappy, 
02 is Sick, FF is pregnant, although I am sure this requres another 
memory area to be changed that I haven't found yet. Byte 5 is for 
the pattern of the animal, well I think anyway, still checking this 

Please note that this is still being tested and the information 
here isn't final.


Active Data - Starting from 0000168A
Game 1 Data - Starting from 0001228E
Game 2 Data - Starting from 0001328E


Active Data - Starting from 000016B2

Active Data - Starting from 00001702
Game 1 Data - Starting from 00012306
Game 2 Data - Starting from 00013306

3.6 How to make new animals

It's possible to make new animals using all that is discussed in the
previous sections relating to the animals.  Enter the name you want
into a free space (ending it with FF of course) and then decide whether
you want a male or female animal, young or adult, (or in the case of 
chickens, just the affection and age of the animal) and then you can set
an affection rating for it.... simple isn't it? ^_^

Again this is still being tested, but previous experiments have been
successful.  Enjoy!

3.7 Tools Menu

Here is the addresses that affects the tools in the menu. I cannot find
the last item, the egg, anywhere at the moment. So please don't mail
about that.
With the first three addresses, the value of the byte determins the 
item that is available. Example, address 3 values. If it is set to 01
then the brush is active. If 10 then horse medicine is active. This is 
the same as the condition/gender for animals where you can combine
For a full list of values see section 4.

These are the addresses for other items like the makers for butter,
cheese and other things. Also household items are kept here too.
Like the first three addresses from the section above, these items are
controlled by single bits. You can also add them together to get more
than one.
See section 4 for a list of all values.

3.11 Shipping Storage

This section is long and is a little complicated. It would help if you 
could add hexidecimal numbers to make sure you don't go over 63 hex. Or
you could use a calculator. :p
Well, now starts the complicated bit. For perishable items, such as
the crops, milk, eggs etc. you have 7 different values for them. Each 
value stands for the amount of crops put into the storage on what day
of the week, the values start at Monday.
An example would be 0A21 0012 1A02 00. If the current day is Sunday,
any items put into the storage would be placed into the last byte.
The same would go if the current day was Wednesday, then any items put
in would be added to byte 3. When you take them out, they are taken out
from the current day first, then i think the previous day.
The way the game deals with perishable items is easy. Using the above
example, if the current day was Sunday, then when it moves onto
Monday, the byte for Monday, i.e. the first byte is set to 00. This is
to represent that the items have been there for too long and have now
become rotten.
Also remember that you cannot have more than 99 items, thats 63 hex
spread between the 7 days.

Well, here we go. First the perishable items.

3.12 Misc Stuff

And to finish off with, how can i forget the good old lumber, fodder and
gold!  Here ya go!

If you put your lumber to higher than 799, it will mess up one event in 
the game with Billy. This event is when he asks for lumber to repair the
lighthouse. He always asks for 200 more lumber you have at the time he
asks you. So until you get the event, make sure your lumber is 799 or
less. Thats 31F hex, you would have to put it in memory as 1F03.

5. Credits

Hmmmm this is an easy bit to write isn't it?
At this time of writing credits go out to
Crescens2k (my brother) for his help in finding things in the state
ragewarrior for the great work in hacking HM3, especially finding the
hex values of the letters and numbers and the partner's love code both
of which made finding the letters and the partner's love in the state
files extremely simple.

If you want your name here in rather natty pixels, it's simple, 
contact me with some information which i don't have in this guide and
you get your name here.  My e-mail address is in the next section.

6. Contact the Author

The author = me, lil hentai fairy and i can be contacted on
that also happens to be my MSN Messenger address too.

when writing to me, please put 'RE: hm3 guide' in the subject line so
