Hello Gentlemans and Ladywomans! I am here to bring you this very special tutorial.
With a new type being added in Gen VI, hackers want to stay up to date and add this new type. However, they usually just replace the ??? type but this messes up Struggle and eggs. So, here I am with this tutorial, complementing DestinedJagold's tutorial. Check it out if you're using Ruby/Emerald

For this tutorial, you need:
1. NSE 2.X
2. A hex editor, I have HxD
3. A Fire Red 1.0 rom

This comes in 3 parts, The Icon, The Chart and The Name.
HERE WE GO! LETS'A GO!

PART 1: THE ICON

Spoiler:

First, open up your Fire Red rom in NSE 2.X


Now, press navigate and a window will pop up. On the right, press the + next to "Pokemon", then "BPRE" which the code for Fire Red, then "Hud", then "PKMN" then finally, click "Status"

You'll get something like this:


Now, the palette is wierd as, so in the Palette section, type in E95DBC. Now press Open, and close the small window as you'll no longer need it.


Now export it. Go to "File", "Export" then "Export Bitmap" or just press "Ctrl + Shift + E"


Save it somewhere, then edit.


Just do whatever you want. In this case, here's a fairy type icon thingy that is used in 11bayerf1's FR rom base. You can use it if you want, I think.


It is a bit bigger, but don't worry. So open up NSE 2.X again, and go to the image but this time, change the "height" to 18, or however tall your image is, divided by 8.
Now, click "File", "Import", "Import Sprite Data" or just press "Ctrl + I".
Press "Load Sprite", click your sprite now.


Change the drop box to "Image + Palette". Now import it.


Mind the weird palette on mine. I did things in a different order, but the result is the same.

Now, you have to insert it into a different part of the rom, as it is now bigger than the original image.
So go to "Insert" than "Image Data".


Now, if its a new rom, you'll probably get the same offset as me, but if not, it doesn't matter anyway. So do that.

Do the same thing for the "Palette Data"

Close NSE and open up the rom in a hex editor.
Now find DC5DE908 by using Ctrl + F or whatever your program uses.


Press okay, then you get it. Now replace it with your pointer. But first, we need it in a format the game understands. Don't know how to change it? Look below!

Spoiler:

First, take any offset > ABCDEF
Split it into sections of 2 > AB CD EF
Reverse the 3 sections > EF CD AB
Then slap 08 on the end of it > EF CD AB 08
There ya go!

So in my case, I've got 00 00 80 08, which is quite bland. Anyway, now replace the original pointer with the new one. There's only 1 case so that's the only one.

Then, find the palette pointer, which is BC5DE908, and replace it with the reformatted pointer of your palette data.

Anyway, you may think you're done, but now the hardest part comes.

Go to the offset 452C94 using the Ctrl + G or Go to option.
You'll come to a bunch of hex.


This actually states the position of the icon. The code is split into parts of 4, the first 2 bytes are the size of the icon, and the 3rd is the position, the 4th is for alignment I believe. Now, because you expanded and moves the "-Type-" and other icons, you'll only need to edit the last 5 entries. Now, to figure out the co-ordinates, look at the second entry.

"20 0C 20 00" This is the entry for the Normal type. 0x20 and 0xC become a width of 32 and a height of 12, which is the same for every type. The "20" in the 3rd position is the co-ordinate.

So, to get the co-ordinate of, in this case, Fairy, take 20 from the Normal type. Count how many rows beneath the Normal Icon is the Fairy Icon, in this case 4. Multiply this by 20, then add it to the 20, in this case 100. Wait whoops, its in hex, so its 0xA0. Then, Count the amount of columns the Fairy icon is away from the Normal icon, in this case 2. Multiply this number by 4, then add it to the final product. So, the co-ordinates for the fairy icon are 0xA8. You can use this "algorithm" to figure out the other co-ordinates as well.

Anyway, go to the final entry, which is 28 0C E8 00 and change to to 20 0C E8 00, because the size used to correspond to the "-Type-" and other icons which are bigger than the type icons, so change the 28 to a 20 as well. Not done yet, as we also moved the co-ordinates of all of the "-Type-" icons as well, so in this case:

"Ignore the 28 which isn't changed into a 20, I forgot to do it in this shot"

If you added more types then the amount of entries provide, move the entire hex into a new location, add some more entries, then repoint. Simple.
Now to test. In this case, to add the new type, just change any type on any Pokemon to 0x16, any other new types start at 0x18 because Nintendo.

Success! The Icon has now been added!

PART 2: THE CHART

Spoiler:

Now we come to the hardest part: changing the type effectiveness of your new type.
Okay, we're gonna need to open up our hex editor.

Now go to your "Goto" function and type in 24F050
You'll have a bunch of hex here:


Now, we have to move this to free space, as you'll most likely make new entries. So select the entire 150 block, and select "Copy" or just Ctrl + C
Now move to some free space, select 150 blocks, and press "Paste


Hooray! Now, it is time to edit in our new type effectiveness.
First let's examine this data. Take the first entry:
00 05 05

Type effectiveness is placed in 3 bytes.
The first byte is the attacking type, the second the defending type, and the third, the effectiveness.
The types in hex are :

Spoiler:

Normal = 00
Fighting = 01
Flying = 02
Poison = 03
Ground = 04
Rock = 05
Bug = 06
Ghost = 07
Steel = 08
??? = 09
Fire = 0A
Water = 0B
Grass = 0C
Electric = 0D
Psychic = 0E
Ice = 0F
Dragon = 10
Dark = 11
The new type is 0x16
Any new type after this begins at 0x18 and on ward

Now using this data, you can see that 00 05 05 translates into Normal, Rock, 05.
If you know pokemon, you'll know that the 05 represents 0.5x damage as Normal is not very effective against Rock.
The other damage multipliers are:
05 = 0.5x
00 = 0x
14 = 2.0x

But you're not restrictly stuck with these. You can go all the way FE or 25.4x damage which is insane! How to figure out new damage multipliers?
Take your multipler, e.g. 5.6x
Multiply by 10 e.g. 56x
Now convert into HEX e.g. 0x38

Okay, so you've figured out the way the chart works, now to edit right? Now exactly.
Let's look at this piece of data at the end.
FE FE 00 00 07 00 01 07 00 FF FF 00

Now the "FE FE 00" signifies that anything after this point is affected by Foresight.
So the 00 07 00 which is Normal Ghost 0x and 01 07 00 Fighting Ghost 0x are affected by Foresight.
Then we have FF FF 00 which signifies the end of the chart.
WE HAVE TO KEEP THESE PARTS AT THE END.

Okay, so to add a new effectiveness, just copy that piece of code, and move it down however many new effectivesnesses you'll add x3. For an example, I'll only move them down 3 spaces.
Now the actually adding. Using the info above, I'm sure you can make your own weaknesses and strengths on your own.
But here's an example.

I want Fairy to hit Super Effectivie on Fire
Okay so this new type is 0x16 and Grass is 0A and 2x/Super Effective Hit is 14.
So my code is 16 0C 14. Insert it into the new space and done!

Hooray!

Now if you want you're new effecvtiness to be affect by Foresight, just move the FF FF 00 at the end 3 bits and add it in.
But make sure the damage multiplier is 0x, which is 00.
Okay save your rom and you're finally done....kinda.

We're gonna have to repoint the chart.
So now, find the pointer: 50 F0 24 08


Now, replace it with your pointer, in my case: 00 24 80 08

There's a few occurrences, so keep finding the old pointers and replacing them.

Okay. Once you've replaced all of the pointers. You're done! Now to test it in game.

I made "Tackle" into a "Fairy Type" to make this easier.


Now to test:


Success! We're now done with the second part!

PART 3: THE NAME

Spoiler:

Now what we're editing here is hard to explain. So here's a picture.


Here, you can see a bunch of gibberish in the corner, even though the move Tackle is now a Fairy type. We're gonna change this.

So open up your hex editor again and go to the "Go To" function. Go to 24F1A0
The data we're concerned with is here:


Okay, so now we've got a bundle of random hex. Except that it isn't. It's actually letters.
Using this reference:

Spoiler:

A = bb
B = bc
C = bd
D = be
E = bf
F = c0
G = c1
H = c2
I = c3
J = c4
K = c5
L = c6
M = c7
N = c8
O = c9
P = ca
Q = cb
R = cc
S = cd
T = ce
U = cf
V = d0
W = d1
X = d2
Y = d3
Z = d4

We can see that these are the names of the types. In this order:
NORMAL, FIGHT, FLYING, POISON, GROUND, ROCK, BUG, GHOST, STEEL, ???, FIRE, WATER, GRASS, ELECTR, PSYCHC, ICE, DRAGON, DARK.
The "FF"s represent the end of the name and the "00"s are for alignment.

So, in order to edit this, you are gonna have to, guess what, repoint the data to free space.
So I move it to 802560 and now we have:


Now what happens next is that, Dark is type 0x11, and Fairy is type 0x16, so we need some space between the entries. So, what you need to know is that each entry is 7 bytes long. So, just create a string of 7 bytes that contain 6 00s and 1 FF and that will be alright. Do this 3 more times, than add the Fairy name. In this case, you can just copy the data I have.


Now, we have to repoint. The original pointer is A0F12408, and replace it.


My new pointer is 60258008 by the way. There are 5 cases so its a short task.


Now to see the results:

Success!
You've now successfully added a new type!

And that's it. If you read all of this, you should be able to create many new types, if you leave enough space. If you see any mistakes, please post it in the thread. Or just comment.

Excuse me I can't understand this, could you guide me by image? (Sorry for my bad English)

So, to get the co-ordinate of, in this case, Fairy, take 20 from the Normal type. Count how many rows beneath the Normal Icon is the Fairy Icon, in this case 4. Multiply this by 20, then add it to the 20, in this case 100. Wait whoops, its in hex, so its 0xA0. Then, Count the amount of columns the Fairy icon is away from the Normal icon, in this case 2. Multiply this number by 4, then add it to the final product. So, the co-ordinates for the fairy icon are 0xA8. You can use this "algorithm" to figure out the other co-ordinates as well.

Anyway, go to the final entry, which is 28 0C E8 00 and change to to 20 0C E8 00, because the size used to correspond to the "-Type-" and other icons which are bigger than the type icons, so change the 28 to a 20 as well. Not done yet, as we also moved the co-ordinates of all of the "-Type-" icons as well, so in this case:

"Ignore the 28 which isn't changed into a 20, I forgot to do it in this shot"

If you added more types then the amount of entries provide, move the entire hex into a new location, add some more entries, then repoint. Simple.
Now to test. In this case, to add the new type, just change any type on any Pokemon to 0x16, any other new types start at 0x18 because Nintendo.

i dont really get this part can you explain it to me some more??

Which is the offset of Bulbasaur? Thank you

Click to expand...

Dragoon said:

You could easily edit the type in YAPE by editing the type constraints in the inis. Making the maximum types 19 and adding in the new type as 18. Otherwise, you can use the offset listed in the YAPE ini as well as using bulbapedia to help edit the type.

I opened the romdata.ini file and changed the MaxtypeVal from 17 to 19

Spoiler:

but nothing happened in YAPE

Spoiler:

. What should I do next?

Nice Tutorial, really helped a newbie like me, but I have a problem, It says that YAPE Has an error readomg Base Stats every time I make Bulbasaur Fairy Type and save it, Yape cannot read the ROM, why is this? It shows up as Fairy in The game but YAPE apparently cannot read the Base Stats? Help D:
