JPAN's Hacked Engine for Dummies Tutorial

Pokemon Fire Red Hacked Engine For Dummies
Pokémon Engine hacks and additions tutorial
By: Turtl3skulll​

While working with JPAN's hacked engine, I've noticed a lot of the instructions are very poorly written; many assume you know every little thing that is going on, and thus a lot of examples are completely voided. I've began rewritting his manual in a friendlier way, one which (hopefully) any beginner with scripting knowledge may be able to look at and understand without the need of carefully reading every word of the document and having to put one-and-one together to figure out an example that was briefly talked about before that is needed.
I will attempt to update the manual to make it as user friendly as possible, and include every special as soon as I get it fully working.

I'll use this format:

NAME OF SPECIAL & ITS NUMBER
BRIEF DESCRIPTION
A SCRIPT EXAMPLE
EXTRA NOTES ON IT

DISCLAIMER: I will not include everything the original manual had. These will be examples of how to script the specials he created, and therefore they will not be explained in full detail, that's what his manual is for & you may look at that for in-depth explanation on his code.

If anything is wrong, needs more explaining, or I missed a special and you know how to explain it feel free to tell me & I'll add it onto this. Hope this helps some of you out :)



Multichoice boxes

Spoiler:

Multichoice boxes have 2 special, being special 0x24 and special 0x25

They contains 7 boxes to use, ranging from 0x20 – 0x25, which define how many choices you wish to have.
0x20 – 2 Choices
0x21 – 3 Choices
0x22 – 4 Choices
0x23 – 5 Choices
0x24 – 6 Choices
0x25 – 7 Choices

Special 0x25 - Load Pointer from Script Bank

Spoiler:

Special 0x25 uses pointers given in the script to load the data into the multichoice boxes
Uses Setvar 0x8006 --multichoice slot
Example Special 0x25:

Spoiler:

For 2 choices:

Spoiler:

#org @start
lock
setvar 0x8006 0x0 ------------------'sets 1st choice slot
loadpointer 0x0 @1 -----------------'loads '@1' to the 1st choice slot
special 0x25 -----------------------'prepares the 1st choice slot to be shown
setvar 0x8006 0x1 -----------------'sets 2nd choice slot
loadpointer 0x0 @2 -----------------'loads '@2' to the 2nd choice slot
special 0x25 ------------------------'prepares the 2nd choice slot to be shown
Multichoice 0x0 0x0 0x20 0x0 --------'the 3rd 0xYY, is which box you'll use; 0x20-0x25, accordingly. Rest are filler
release
end

#org @1
= Choice 1 'This is the text which will appear in choice slot 1
#org @2
= Choice 2 'This is the text which will appear in choice slot 2

To add a 3rd or 4th choice you just add another 'setvar 0x8006 0xYY' another 'loadpointer 0x0 @something' and 'special 0x25', as shown below, as well as changing the Multichoice from 0x20 to the box with the desired choice amount.

For 3 choices:

Spoiler:

#org @start
setvar 0x8006 0x0
loadpointer 0x0 @1
special 0x25
setvar 0x8006 0x1
loadpointer 0x0 @2
special 0x25
setvar 0x8006 0x2
loadpointer 0x0 @3
special 0x25
multichoice 0x0 0x0 0x21 0x0

#org @1
= Choice 1

#org @2
= Choice 2

#org @3
= Choice 3

Special 0x24 - Load Pointer by Variables

Spoiler:

Special 0x24 uses pre-defined variables to load the data into the multichoice boxes
It uses:

Spoiler:

Setvar 0x8004 --to load the lower half of a pointer (B in 0xAAAABBBB)
Setvar 0x8005 --to load the upper half of a pointer (A in 0xAAAABBBB)
Setvar 0x8006 --multichoice slot

Example Special 0x24:

Spoiler:

#org @start
lock
setvar 0x8004 0x3848 ------'The pointer is 08803848, this takes the lower half
setvar 0x8005 0x0880 ------'The pointer is 08803848, this take the upper half
setvar 0x8006 0x0
loadpointer 0x0 0x0203f4a0
special 0x24
setvar 0x8004 0x383f ------'The pointer is 0880383f, this takes the lower half
setvar 0x8005 0x0880 –----The pointer is 0880383f, this take the upper half
setvar 0x8006 0x1
loadpointer 0x0 0x0203f4a0
special 0x24
multichoice 0x0 0x0 0x20 0x0
release
end
#org 0x803848
= Text 1
#org 0x80383f
= Text 2

The max number of choices allowed are 7, if you attempt to load 'Setvar 0x8006 0x7' or higher (which would be 8 choices) it will fail.
Every single loadpointer must be pointed to some offset whether or not it contains text, else game will crash.
Multichoice box text must be under 20 characters to be properly displayed, and According to JPAN will not display special characters such as the \v\hxx or coloring, but its worked fine for me.

Runtime Trainer Customization

Spoiler:

The trainer OW, trainer backsprite, and Trainer card can now be changed.

The variables below contain the variable to use according to what you wish to change:

Spoiler:

Variable Changes
0x4054 Standing & Walking
0x4055 Bike
0x4056 Sitting (Surfing)
0x4057 VS Seeker
0x4058 Fishing
0x4059 VS Seeker on Bike

Examples:

Spoiler:

Trainer Sprite

Spoiler:

#org @start
setvar 0x4054 0x025----------'variable 4054 will change the standing and walking sprite's, 0x25 can be found in Advance Map, under "Picture no:" just convert that number in the box to hex, to use that sprite.
callasm 0x805BE61------------'Changes the sprite instantly, and allows the script to continue
end--------------------------'0x025 will change to the little girl; this can be changed according to the OW you want to become, Example: 0x87 will change the OW to the Lapras OW.

For the sprite to change, a new map must be entered, or you can just call the ASM routine in this example script (Credit to diegoisawesome for finding this routine).

Trainer Card

Spoiler:

For Boy

Spoiler:

#org @start
setvar 0x4060 0x8
end

For Girl

Spoiler:

#org @start
setvar 0x4061 0x8
end

0x8 is just the image that will replace the original
Trainer cards use variables 0x4060 for boys and 0x4061 for girls.
To switch back to the original hero/heroine you use 0x87 & 0x88 accordingly.

Trainer Backsprites

Spoiler:

This is practically its own little tutorial and thus I won't explain, since it requires changing palletes and images, if anyone wants to make a tutorial of this or has made their own, let me know and I'll link to your tutorial.

Poke-Decrypt Specials:

Spoiler:

The following specials are used to change a Pokémon's internals, such as EV/IV Pokeball, capture location, Ribons, and Pokerus.

Special 0x6 – Pokemon Decrypt/encrypt

Spoiler:

A toggle to open and close a Pokemon's 'DNA' to alter, alone its useless therefore I'll explain a few more specials and then I'll give an example.

BufferPartyPokemon

Spoiler:

Bufferpartypokemon 0x0 0x0
Explanation:
The first 0x0 chooses the pokemon to buffer from slots 1-6 (0x0 – 0x05)
The second 0x0 is the buffers that will be used.
Examples:
#org @start
Bufferpartypokemon 0x0 0x0 -----'buffers 1st pokemon, & the buffer set to \v\h02; the buffer in the script MUST have 2 added when using it as "\v\h0X", thus this one will be \v\h02 since our pointer is 0x0
Bufferpartypokemon 0x1 0x1 -----'buffers 2nd pokemon, & the buffer set to \v\h03
Bufferpartypokemon 0x2 0x2 -----'buffers 3rd pokemon, & the buffer set to \v\h04; \v\h04 (0x2) is the max amount of pokemon to buffer, no more than 3 pokemon can be buffered at a time, after this, the game will load, the rival name and some other things.
Msgbox @hi 0x6
end

'strings
#org @hi
= \v\h02, then \v\h03 'meaning it'll be read [buffer1], then [buffer2]

release
end

#org @fail
msgbox @not_cool 0x6

end

Special 0x15 – Give Held Item

Spoiler:

Gives a selected Pokemon an item
Uses Setvar 0x8005 0xY
The 'Y' being the Item ID

Example:

Spoiler:

bufferpartypokemon 0x0 0x0
setvar 0x8004 0x0
special 0x6
setvar 0x8005 0xX –------'The X can be replace with the item ID
special 0x15
special 0x6

Special 0x16 – Change Pokemon Species

Spoiler:

Changes selected Pokemon Species
Uses Setvar 0x8005 0xY
The 'Y' being the Pokemon ID

Example:

Spoiler:

#org @start
bufferpartypokemon 0x0 0x0
setvar 0x8004 0x0
special 0x6
setvar 0x8005 0xX –------'The X can be replace with the Pokemon ID
special 0x16
special 0x6

DISCLAIMER: The species switched to MUST have the same EXP curve as the current or game will crash upon looking at the POKEMON screen.
According to JPAN entering a battle fixes this issue, but haven't tested it.

Special 0x17 – Change Pokemon Attacks

Spoiler:

Changes selected Pokemon Attacks
Uses Setvar 0x8005 0xY
The 'Y' being the Slot number 0-5
Uses Setvar 0x8006 0xZZ
The 'ZZ' being the attack number, 0x0 can be used to erase the attack

Example:

Spoiler:

#org @start
bufferpartypokemon 0x0 0x0
setvar 0x8004 0x0
special 0x6
setvar 0x8005 0xX –------'The X can be replace with the attack ID
special 0x17
special 0x6

This code can (and usually should) be used in conjunction with another special, this one original from the game. Special 0xdc not only accesses the pokémon slot at 0x8004 (the one used at the decryption code) and opens the status screen's Attack screen, and the chosen attack is saved in 0x8005
This code will automatically check for empty slots first, and then, if all are occupied
replace the slot with the given attack. It also restores that attack PP fully, and removes
all PPup slots used.

Special 0x18 - Check Pokemon Species

Spoiler:

Check (compares) the species of a pokemon and return a yes or no
Uses Special2 LASTRESULT 0x18
Example:

Spoiler:

#org @start
special 0x9f ----------------------------'pokemon select screen
waitstate
compare 0x8004 0x6 --------------'compares if 'b' is pressed (cancel)
if 0x1 goto @cancel
special 0x6
special2 LASTRESULT 0x18 ------'calls special 18 (apparently 'special2' not 'special')
compare LASTRESULT 0xYY -----'compares to 0xYY; YY being pokemon number
if 0x1 goto @yes
special 0x6
release
end

This will just compare a pokemon and give back the result. It will NOT tell you the pokemon species, or do anything else. Use this as an if statement with a pokemon instead of a question.

Party Specials

Spoiler:

Party Specials seem to always fail me, all status flags equal sleep & hp does not check correctly, I will keep looking, but the scripts should be the correct way of doing it

Special 0x52 - Temporary Status inducer

Spoiler:

temporarily adds status effects to wild pokemon

Uses 0x8004 with the following key

Spoiler:

0-2: Sleep bits.
3: Poison
4: Burned
5: Frozen
6: Paralysis
7: Badly poisoned

Uses 0x8005 as the number of changes.

Spoiler:

setting it to 7 equals 1 pokemon appearing, 0E(14) equals 2, etc. Multiply by number of pokemon to appear like this

Example:

Spoiler:

#org @start
setvar 0x8004 0x5 '---- set status to frozen
setvar 0x8005 0x7 '---- set turns for 1 pokemon
special 0x52

Special 0x53 - Status inducer canceller

Spoiler:

Cancels special 52
takes no argument; it can be placed in any script as is.

Special 0x54 -Permanent Status Inducer

Spoiler:

Permanently applies status effect to all encountered pokemon
Uses 0x8004 same key as special 0x52

Example:

Spoiler:

#org @start
setvar 0x8004 0x6 '----Set status to Paralysis
special 0x54
release
end

DISCLAMIER:

Spoiler:

there is a bug with this one, that if you use a healing function (special 0x0), one that creates pokémon (givepokemon, giveegg, special 0x1bb…) or simply withdraw a pokémon from the box, the Status creating routine is activated, the same one I changed to create the Status always on effect. As such, perfectly healthy pokémon enter the pokecenter and come out poison or paralyzed… -JPAN

Special 0x55 - Permanent Status inducer canceller

Spoiler:

Cancels special 0x54
Works the same as special 0x53

Special 0x62 - Earase Party Pokemon

Spoiler:

Uses 0x8004 0xY 'Slot to delete, 0xf deletes whole party

Examples:

Spoiler:

Example #1 - 1st slot Pokemon:

Spoiler:

end

Example #2- Erase full party:

Spoiler:

#org @start
setvar 0x8004 0xf

Special 0x56 – Swarm-roaming Pokémon Changer

Spoiler:

Vars Used:

Spoiler:

Uses Setvar x8004

This is the only one I will explain, until I practice the others:
0 to 0x3fff-> The number of the Pokemon wanted (Use YAPE to see correct numbers as there is a gap between Celebi and Treecko)

0x4000-> 0x8015: The pokemon number IN the variable stored in 0x8004
0x8000-> 0xfffc: not defined
0xfffd-> specific pokemon stored at a pointer kept in two variables, 0x8008 0x8009.
0xfffe-> specific pokemon stored at a pointer, that must be placed by hand in 0x0203f488
0xffff-> specific pokemon stored at the LoadPointer location

Uses Setvar x8005

Chance pokemon will appear out of 65536
0x0-0xffff (0-65536)
50% is 7fff (32767)

Uses Setvar x8006

Amount of roaming Pokemon 0x1,0x2,etc.
0x0 means unlimited, will keep appearing

Uses Setvar x8007

uses lower and upper halves:

Lower half is location given by:
each bit either being 0 or 1 depending on what you want
Bit 0 = Grass
Bit 1= Surfing
Bit 2 = Tree/rock-smash
Bit 3 = Fishing
1001 (bit 0=1, bit 1=0, bit 2=0, bit 3=1) would make pokemon available on grass and fishing
1110 (bit 0=1, bit 1=1, bit 2=1, bit 3=0) would activate it in grass, surfing, & tree/rock-smash
it must be written in hex though, so 0x9 and 0xE respectively

The Upper half is the pokemon level:
level 80 being 0x50

Example:

Spoiler:

#org @start
setvar 0x8004 0x85 ------' sets pokemon to Eevee
setvar 0x8005 0xfd70 –--' make the chances of appearance 99% (64880)
setvar 0x8006 0x1 -------'Will appear once
setvar 0x8007 0x500e –' appear by all except fishing
special 0x56
release
end

You can only replace the level for Roaming codes, that is, only for the ones in that 0x8006 = 1. For swarms, however, you cannot.

Special 0x57 - Swarm-roam Pokemon Canceller

Spoiler:

Cleans Special 0x56 for its next use.

Special 0x58 - Wild Pokémon Data Switch

Spoiler:

Changes the current map's pokemon data to a predefined set you created.

Example:
All script using offset 0x810000

Script by Loadpointer :

Spoiler:

msgbox @change 0x2
loadpointer 0x0 0x810000
special 0x58
release
end

#org @change
= The wild pokemon have been changed.

Script by Vars :

Spoiler:

msgbox @change 0x2
setvar 0x8008 0x0000
setvar 0x8009 0x0881
setvar 0x8005 0x0
setvar 0x8006 0x1
special 0x58
release
end

#org @change
= The wild pokemon have been changed.

Script by writebyteoffset :

Spoiler:

msgbox @change 0x2
writebytetooffset 0x81 0x203F48C
writebytetooffset 0x00 0x203F48D
writebytetooffset 0x00 0x203F48E
writebytetooffset 0x08 0x203F48F
special 0x58
release
end

#org @change
= The wild pokemon have been changed.

Hex edit Part 1:

Spoiler:

At the offset defined in the script (in my case 0x810000) write:
XX 00 00 00 YY YY YY 08

XX - determines location of wild data... such as pokemon appearing in water, grass, tree/rock, and fishing.
table for this:

Spoiler:

Bit 0 = Grass
Bit 1 = Surfing
Bit 2 = Tree/Rock
Bit 3 = Fishing

So activating Grass and Fishing would be 1001 (in binary) so 0x9 in hex.

00 00 00 - filler
YY YY YY - pointer to wild data (in reverse the 08 is already included so you just need the offset in reverse, don't add another 08)

Hex edit Part 2:

Spoiler:

At the offset defined by the "YY's" in part 1 you will need to place the wild pokemon data.
It goes as followed:
AA BB CC 00

AA = Min Level
BB = Max Level
CC = Pokemon Index Number
00 = filler

For grass wild data you will need to fill up this info 12 times total
For Surfing wild data you will need to fill up this info 5 times total
For Tree/rock wild data you will need to fill up this info 5 times total
For Fishin wild data you will need to fill up this info 10 times total

Example:
For an all Eevee party ranging from level 25-32 in grass:
19 20 85 00 19 20 85 00 19 20 85 00 19 20 85 00
19 20 85 00 19 20 85 00 19 20 85 00 19 20 85 00
19 20 85 00 19 20 85 00 19 20 85 00 19 20 85 00

HUGEEEEE thanks to Lance32497 for helping me figure this one out.

Special 0x59 - Wild Pokémon Data Canceller

Special 0x97 - Random Grass Battle

Spoiler:

No Arguments
Creates a random grass wild battle

Special 0x9c - Old Man Battle For All

Spoiler:

The Old Man battle for any Pokemon
Uses Setvar 0x8004 0xY 'being the Pokemon species
Uses Setvar 0x8005 0xY 'being the Pokemon level

Example:

Spoiler:

#org @start
setvar 0x8004 0x1 -----' Bulbasaur
setvar 0x8005 0xA -----' Pokemon level 10
special 0x9c -----------' The special

end

The old man can catch no legendary except for the bird trio, Blissey and a few others in the legendary region.

Speical 0x156 - Ghost Pokemon Battle

Spoiler:

The Old Man battle for any Pokemon
Uses Setvar 0x8004 0xY 'being the Pokemon species
Uses Setvar 0x8005 0xY 'being the Pokemon level
Uses Setvar 0x8006 0xY 'being the held item

Example:

Spoiler:

#org @start
setvar 0x8004 0x1 -----' Bulbasaur
setvar 0x8005 0xA -----' Pokemon level 10
setvar 0x8006 0x0 -----' No Held Item
special 0x9c -----------' The special
release
end

This code also can use all Pokemon legendary except for the bird trio (ask not why), blissey and a few others in the legendary region.
I remind you that this code is originally meant to make a battle with an uncatchable ghost pokémon that has no ghost on its type.
This will also not crash if you don't have the SILPH SCOPE, so it will work w/o it.

Walking Scripts

Spoiler:

"Basically, this feature allows you to create your own special scripts that are activated each time you take a step, well, most of the times you take a step.
There are some other scripts that will always run first. The Egg hatching script, the whiteout script or every step-on (green) script will always beat this one into execution, so you have to take these into consideration if you need that script to run all the time (such as calling the walking script before starting a normal step-on one).
Also, this script is, by definition, a blocking script, meaning that every script you make here must end with the release or releaseall commands.
This script is indicated to make some small checks, manipulate the landscape, and the occasional message, like the Phone script in Gold." -JPAN

This special contains a max 4 slots to store the walking scripts into as a table.
They are located 0x1a4e2c.
Only 1 can be executed at a time, they are selected by using:

Setvar 0x407e 0x(1-4)

An extra walking script can be set temporarily by setting 0x407e to 0 and loading a pointer to the RAM address 0x0203f4f0, this one will take priority over the ROM table.

Special 0x81 - Load Walking Script Pointer

Spoiler:

Loads the pointer from the loadpointer bank 0 to the 0x0203f4f0 address to allow execution, is also needed for wildbattles to be activated through this.

Instructions:

Spoiler:

Instructions to this are:

"First, you have to make the script you want to activate on every step. Once the script is compiled, you open a hex editor and navigate to offset: 0x1a4e2c

There are 4 slots for pointers there. Place the offset (reversed) of the script you want to execute with every step in the first slot.

Then, at whatever point you want the walking script to be active (be it through an event script or a level script) just put:

setvar 0x407e 0x1 ---'tells game to access 1st pointer at offset 0x1a4e2c
special 0x81 ---------------' starts the script to activate on every step.

So that's how special 0x81 works, in case anyone else was having trouble with the instructions." (Credit to metapod23)

Example #1:

Master Script

Spoiler:

#org @start

end

Money On Step

Spoiler:

#org @start
givemoney 0xA 0x0 ---------------'Gives $10 on every step
release
end

This example uses the 1st pointer in the offset 0x1a4e2c.
Assuming the offset for the 'Money On Step' script was 0x8003f9, you'd go to a hex editor and in the 1st slot you'd write over '00 00 00 00' with 'f9 03 80 08'

special 0x97 ----------------------'If it equals 10, it creates a willbattle
releaseall

#org @none
releaseall

This example uses the 2nd pointer in the offset 0x1a4e2c.
Assuming the offset for the 'Random Wild Battle' script was 0x8003d8, you'd go to a hex editor and in the 2nd slot you'd write over '00 00 00 00' with 'd8 03 80 08'

Special 0x2f – Key Dumper

Spoiler:

This Special dumps the keys pressed & returns them to be compared against a specific combination entered.

No Arguments

Returns values? Yes

Spoiler:

0x0 to 0x3ff, one bit per key, following the same key as the GBA specifications, that is
Key per bit, starting at the lowest:

0 A
1 B
2 Select
3 Start
4 Right
5 Left
6 Up
7 Down
8 R
9 L


But what if I want the player to press a wacky combination involving A+B+L, then you would just add them up in a calculator in binary mode:

A | B | Select | Start | Right | Left | Up | Down | R | L
1-|-1-|---0---|--0---|--0---|--0--|--0-|--0---|-0-|1

now you just add it backwards, that would be 1000000011, 0x203 hexadecimal.

Increasing Max Money Amount

Spoiler:

You can now hold up to 999 999 999 money! That's nearly 1000 times more money!
This was never added to the manual, but JPAN talked about adding this in a future release, i dunno if it was added as of version 1.1, but here it is anyways:
This replaces 7 bytes, and here's how to do it:

Spoiler:

In a Hexeditor goto:
0809fdd4 replace |3f 42 0f 00| with |ff c9 9a 3b|------------------' (999999 for 999999999)
In the following offsets replace that one byte from |06| to |09| ----'(6 digit display for 9 digit display)
0808a006
0809fe52
0809fe62

Done, you should be able to have that much money now.

So I've started using JPAN's engine because it seems like the hack I was working on is broken. (Might as well start over)

I found out I'm able to change IVs, and I want to do so through the pokemon selection menu. I feel like I'm close to being able to, and I understand how most calls work, but I'm having trouble understanding what each variable does, and how it is used in conjunction with other variables. What are the limits to these variables? etc

Any clue what I'm doing wrong? I have successfully made all IVs max, but it only happens to my first pokemon. The only time its worked with the menu, I've had to use the item twice to see results. Its really odd.

Not sure what you mean by the limitations the variables have, PM me and I'll be glad to answer what I know about them.

As for what you did wrong, its not with JPAN's code, but with how you're calling the pokemon from their menu, I don't remember how to call them properly, I tried it and ended up changing the stats of everyone in my party XD try using diego's tutorial on XSE and see if you fix the way you called it, I'll look around my scrap codes cuz I think I have the solution there somewhere, if I find it I'll let you know.

Also how do you know it only happened for the 1st pokemon, did you check it with the checking specials? if so, could you post that script too, that may help.

This is really useful thank you!

I figured it out. It took 6 hours, but I finally understand everything now.

Ok I'm glad you figured it out, sorry for taking a week to answer I was out of town.

If you got the solution I'd like to know it, in the case I ever run into that problem, or need to help someone else with it.

Thanks for posting your code on it, I was always a little confused on if the worked correctly. Thanks for that, I'll use your code to correct anything I've done, thank you!

No problem! Glad you're using the code! I've tried it with multiple things, including renaming pokemon, etc and it works. I really appreciate you taking the time to explain the other things. I still use this post as a reference.

I feel like you're thanking me for things I didn't do, unless you're referring to my original post :P

Also I meant how did you fix your problem with giving the IVs to the selected slot on the pokemon choosing thing, instead of just the 1st/all pokemon in the party.

I mean on the original post. Thank you for placing everything in one place and giving examples.
And this:
setvar 0x8004 0x1

This controls which slot it gives the stats to. I stuck notes on my code, hopefully that helps.

Didn't see this special on your tut.
SPECIAL 0x18: Check Pokémon Specie
If you want to check if the Pokémon in your Party is Pikachu or somewhat, here's the script

Spoiler:

special 0x9F @Opens the pokemon party screen and stores the slot number of the selected pokemon in 0x8004, 0-5, 7 means cancel
waitstate
compare 0x8004 0x7 @Checks if it presses cancel
if 0x1 goto @cancel
special 0x6 @Decrypts pokemon, no need to set variable 0x8004, it is already set in special 0x9f
special2 0x800D 0x18 @Calls Special 0x18 and stores the value in Lastresult
compare 0x800D 0x19 @Compares if lastresult is 19, which is Pikachu's index number
if 0x1 goto @Yes
special 0x6 @Brings the data of pokemon back to its previous data
end

I've added it now under 'write & editor', Thank you! :)

I think we may use bufferpokemon 0x0 LASTRESULT after special 0x18

 

[Turtl3Skulll]

I think we may use bufferpokemon 0x0 LASTRESULT after special 0x18

I mean... You can, but it works perfectly without it.
I decided to test both, just in case, and the both do the same so I wouldn't use it just to save some memory (yeah I know like 4 bits matters XD )

Hey, could you explain to me how the special 0x58(Wild Pokemon Data Changer) works? I've read it a few times but I'm clueless about what should be done.

Hey, could you explain to me how the special 0x58(Wild Pokemon Data Changer) works? I've read it a few times but I'm clueless about what should be done.

Sadly I don't know how it works, I tried for a few hours today, but no success...

The closest I got to it working was this:

Spoiler:

This is the script:

Spoiler:

msgbox @change 0x2
setvar 0x8009 0x0890
setvar 0x8008 0x0034
setvar 0x8006 0x1
setvar 0x8005 0x0
special 0x58
release
end

#org @change
= I will change the pokemon now.

The pointer set in 8009 & 8008 is 0x08900000 (why does the script have 34 added to it, I know not, its just how others did it and it changed the pokemon to Sunflora instead of ??????? so yeah...)
The data I added to that offset was:

Spoiler:

0A 0C 01 9A
This was repeated about 12 times
That should make Deoxys levels 10-12
