[CLOSED] Extracting A/D/S Deoxys sprite from original ROMs

Hello,

I am working on replacing some a few Pokemon in Fire Red with Normal, Defense and Speed form Deoxys. And I am having difficulties extracting the sprites from original ROMs.

How could I extract the original Attack/Defense/Speed Deoxys sprite out from the original ROM?

G3HS documentation says that the sprite sheet for Deoxys/Castform is just bigger than normal sprites, so I tried to add some offset to the original pointer. It didn't work out so well. I am guessing it is because the image was compressed?

For tools, I am using PokemonGameEditor 3.8.1 (PGE) and POK?MON Gen III Rom Hacking Suite (G3HS). Older tools didn't work well for me.

Also, if anyone knows where I can find Wichu's Advanced Tools, please let me know. I would love to try them out.

I was able to extract the image in 128 x 64 format from the games using Nameless Sprite Editor.
However now I learned that not all images are the same size because while they have the same dimension, they are compressed.
Attempting to overwrite Bulbasaur's front sprite corrupted my Bulbasaur data :(
Is there a way to put Deoxys' other sprites into the game without using the Free Space?
If I use Free Space and want to use PGE to edit the game, I would need to update the .ini file for the ROM, is that correct?

I figured out palette and got the sprite replaced. All is well.
