1. what is a mod?
a mod is a
modification of a game such as Diablo ii
which gives you
new features the original game hasn’t given you (like: new
items, new
monsters and any other changes in the game play).
2. basic stuff you’ll need
to make mods you
will need certain programs such as:
1. mpq2k
2. Microsoft excel (or any other
spreadsheet program).
3. paint shop pro (or any other image
editing program that allows you to apply palettes to an image).
4. tbl editor
5. hex editor(note: you will need a hex
editor only if you plan to hex edit dlls).
6. dc6con
7. psidc6
8. mpqview
9. uniq_ed91g
most of this
stuff is freeware so its for free some of the programs in the list
are not freeware
so you will need to either get a trial or buy the full program.
Here is a link to
a page having all the freeware on it
3. how to make a simple items mod
here you will
learn how to ad a new item to the game and make all items dropped
rare, and allows
how to modify unique and set items.
First how to
modify set and unique items
Open up
uniq_ed91g choose the unique item from the pull down above and simply
start changing
its modifiers with the options to your right(now this was not so
hard) now press
spawn on button (below the unique items stats) press on it now a
message will
appear and say apply to patchstring.tbl choose yes and you have
modified the
unique item(now you will need a chareditor to ad the unique item to
your char and
test your new mod).
To modify sets
you will use the same program as above
Just below the
about button is a invisible button (it will get marked if you
scroll over it)
the set editor screen will appear (it works similar to the
unique editing
screen so there is no big need to explain)
Make all items
dropped rare
Open up mpqview
and choose load data file form the file pull down, choose
d2datall.txt(it
comes with the viewer)
Now choose load
archive choose patch_d2.mpq choose a file called itemratio.txt
from the list,
press save and open it with excel now a message will appear on
the screen saying
would you like to blah blah blah... press ok now you will see
some strange
numbers on your screen here is what you have to change.
I changed the
raredividor and rare columns to 1
now you will have
to put the file back into your mpq so it will work in the
game. First after
you made these changes press save button in excel it will make
2 messages appear
on your screen press ok on both.
Now make sure the
modified itemratio.txt(make sure you always make a backup for
the original) is
inside the same folder as mpq2k, now go down into your start
menu and choose
run now a small message like thing will appear type into it
command.com a
black dos window will appear on your screen in this window find
the folder you
keep all the following files in(all files have to be in the same
folder for it to
work) mpq2k, itemratio.txt, patch_d2.mpq if you found the
folder type in
mpq2k the program will respond and show you a list of options,
now type in:
Mpq2k a
patch_d2.mpq itemratio.txt data\global\excel\itemratio.txt
If you made
everything correctly you may take the modified patch_d2.mpq file
back into your
Diablo II directory, notice when you play the game some of the
rare items you
have equipped may “morph” (change modifiers), and you will find
almost only
rare(yellow items).
Making a new item
Well now after
you did really some of the mod basics you will Probaly want to
advance to an
higher level, making new items is such a level, first you will
need 3 files that
are found in your patch_d2.mpq file(if some of them are not
open d2data.mpq
with the mpqview, the files are: weapons.txt, treasureclass.txt,
string.tbl
First open up
weapons.txt(in excel) and choose the
first row (hand
axe) right click the row and choose copy
and paste as new
row(make sure it pastes it below the hand axe row now its time
to start changing
the new items stats first go to mindam maxdam columns and
change it to whatever(note
mindam can not pass 100)
As you can see I
also changed the name column next we will have to change the
items code go to
code column
change the code to
something else NOTE: never ever ad a code twice except if you
know what your
doing!!!
Because it is a
cloned hand axe you will be able to buy it at charsi once in the
game(note: there
some columns that determine which vendor will be able to sell
the item called
(charsi min, charsi max...) like this for each vendor.
Next open up treasureclass.txt(you
actually don’t have to do that but if you
don’t the item
will not be dropped by monsters) in treasureclass.txt simply ad
your new code to
all the act1 rows you will find in here save both files and
exit excel.
Next open up the
tbl editor(if you don’t know what that is read section 2) once
open select
string.tbl here you will now see a enormous list of cods at the left
screen side and
what they mean on the right side(note if you don’t ad a new code
to string.tbl the
game may mess up!!!)
Choose the ad
code button(+) and type in the code you gave your new weapon
(note: a weapon
code may NOT be bigger then 3 letter, numbers note also that
capital letters
are considered other letters (small a is not the same as capital
a) after you have
ad the code you will have to ad what will be displayed on the
playing screen in
the right screen half type in what the name of the item will
be. If you made
everything until here correctly you will now only need to ad the
files to your mpq
here are the paths to ad the files:
Mpq2k a
patch_d2.mpq weapons.txt data\global\excel\weapons.txt
Mpq2k a
patch_d2.mpq treasureclass.txt data\global\excel\treasureclass.txt
Mpq2k a
patch_d2.mpq string.tbl data\local\LNG\eng\string.tbl
4. how to make a simple boss mod
here we will
learn how to make a boss mod what means that you will be able to
fight bosses
everywhere!!!
For this you will
need the following files:
Levels.txt,
monstats.txt. open up monstats.txt with excel and go down to row
258(Izual) change
spawnable column to 1. save monstats.txt(note: for these of
you that don’t
know what’s the difference between row and column, column is a
vertical line |,
and row is a horizontal line ___.), choose save and load
levels.txt into
excel here you will need to edit a bit more, go to mtot column
and change that
into 1 (choose the first row (bloodmoor) called wilderness 1 now
go to the columns
m1-m25 and make all of them into 0 next go to column m1 and ad
256 into this row
(its 258 -2) now go to column monumin and monumax and make
them both 1 next
go to column utot and make that column 1 make columns u1-25 all
0 now make column
u1 into 256 save your work and exit excel. Now you will need
to put the files
back into your mpq, like all those before run mpq2k an type in:
Mpq2k a
patch_d2.mpq monstats.txt data\global\excel\monstats.txt
Mpq2k a
patch_D2.mpq levels.txt data\global\excel\levels.txt
Launch Diablo ii
and go into the bloodmoor you will be surprised!!!
Note: for full brief
on monstats.txt go to www.phrozenkeep.com
For full brief on
levels.txt go to my site

5. how to make a
simple skill mod
No no no I am not
teaching you how to change the skill gfx, if you wanna learn
that go to www.phrozenkeep.com
Here you will
learn how to make all skills available at any level and without
the need to ad
points to weak skills to unlock the skills coming after them.
You will need the
following file: skills.txt
Open up
skills.txt in excel, now go to row reqlevel and make em all 1 next go to
the rows
reqskill1-3 and make them all 0 save your work and exit excel ad the
file to your mpq
at this location:
Mpq2k a
patch_D2.mpq skills.txt data\global\excel\skills.txt
6. How to make
overall gameplay changes
This is actually
not a tutorial like the above it simply will explain what a
overall gameplay
change is and how you best make them. A overall gameplay change
is for example
what I did in my xyrax(if you haven’t played this mod then take a
look) here--> http://nefarius.go2click.com I changed
the exp you get from
monsters in
normal and much more also ad masses of new items and new and unused
monsters but
still the best way to look at total gameplay conversion is to make
your Diablo ii
version into 1.03 and download the kagero mod(one of the first
mods I have played).
7. Ideas for mods
Easily this is al
up to you... once you will advance to dll hacking nothing is
impossible... but
for the case you have no imagination, eg: you can make all new
skill trees and skills
by modifying the existing ones even make the titlescreen
change ad your
own grafics to the game and much more!!!
8. stuff you have
to know
mods are not
considered cheating even some people might say so, according to
blizzard
entertainment(the creators of Diablo ii) its ok to make mods as long as
you don’t mess
with the copyright and the enduser agreement, but this may not be
so for other
games, so I advise you make mods only if you don’t get in trouble
from it!!! Also
mods may not be sold for profit of any kind all mods must be
freeware if you
want money for mods make your own game and don’t mess with other
games!!! Also I
don’t have any responsibility with what you do with this file...
this file is not
endorsed by any one not even the author himself any uses or
misuses are at
your own responsibility and are nor condoned by the author!!!
9. where can I
reach you???
