[ASM] E | Add All Deoxys Forms That Change w/ Variable

I

I am really excited that I got this working. There's a chance you may run into bugs but I think it's good to go. This routine uses the same code in the game that changes Deoxys form automatically to Speed in Emerald. I went through how the game code changes Deoxys stats and sprites, and realized if you just import a sprite with more forms, you can pick any sprite on the sheet. The same with the stats. So I got this working right now and im so happy its finally working good, so lets get into how to do it

First lets add the sprites. They will be attach below. Open UNLZ and goto 741 for the Front Sprite. Import the front sprite attached and hit Write to Rom (make sure youre on Deoxys already existing sprite). Make sure you select Import Image, Import Palette, Auto Abort, Automatically Fix Pointers. Use FSF to find about 1000 bytes ish, enter the offset for Image, and do same for palette. I used FB0000, and FB1200 I think. Make sure it says pointers were replaced. Now repeat the process for the Back Sprites, goto 1810 in UNLZ and do the same process. Now lets get to the routine
.
This routine uses Variable 0x40DC to determine which form's Sprites and Stats will be shown and used.

40DC = 0 = Normal Form
40DC = 1 = Speed Form
40DC = 2 = Defense Form
40DC = 3 = Attack Form

Only one routine is required to add into the game. It'll be easiest if you write the bytes at offset FE0000. You should have free space there. If you cant do that it shouldnt be a problem.

Now that you have the routine in, you have to add the hooks. There are 2 hooks that feed this routine.
first one, @ offset 0x068A58 , overwrite with 00 4A 10 47 01 00 FE 08. If you didn't use FE0000 change the last 4 bytes to point correctly.

Next hook is at 0x034C3C. Overwrite with 00 4A 10 47 01 00 FE 08 02 4A. Again change pointer if needed.

last thing needed is to add the data for the Stats. The offsets I put them are referenced in my code so they need to be put in the same address that I put them. Unless you Asssemble yourself and change the address. So Copy these bytes and overwrite them at 0xFDFFA0. If you put Routine at FE0000 this is right before that. It should be free.

32 00 46 00 A0 00 5A 00 46 00 A0 00 FF FF FF FF
32 00 B4 00 14 00 96 00 B4 00 14 00 FF FF FF FF
32 00 96 00 32 00 96 00 96 00 32 00 FF FF FF FF

Now to change forms just use an xse script to set form!

If I understand well :
with this method, all captured deoxys have the same form at all time ?
(And the wild/trainer ones still use the normal form ?)

Other than that, the principle seems really good.
Thanks for the tutorial.

Yeah thats the one downfall , all of your deoxys will be the same form. It would be possible to add onto this code a way of storing what type each deoxys yoy have is but it would be alot of work. wild Deoxys are still in normal form, atleast the event one is still no matter what form is selected

This doesn't seem to work at all for Emerald German version

I've found the lang version offsets and they should be absolutely correct
But the game always crashes opening the pokemenu of Deoxys
Only its sprites work seeing it in storage boxes

Here's the routine with German offsets, hoping someone could help to make it work

Buenas. Yo lo que haría sería probar las rutinas y los cambios de bytes del post principal en una ROM limpia inglesa, y ver si todo funciona como debería haciendo las pertinentes pruebas. Si en la ROM inglesa funciona y en la tuya alemana no, es que evidentemente has colocado alguna compensación mal.

Already tried on english rom and works
Offsets found of german version seem correctly so I don't know what the problem is
Anyway it misses icon change at now so I consider it incomplete
Thank you anyway
