[Other] Help editing Deoxys's and Castform's alternate forms sprites and stats

[Myi64]

Essentially I was just wondering if anybody knew how to change the sprites and the stats of Deoxys-Speed, Deoxys-Attack, Deoxys-Defense, and Castform-Sun, Castform-Rain, and Castform-Hail. My friends and I are working on a rom hack and were wondering because none of us can find either the stats or forms. Any help is greatly appreciated.

You can easily use tools like G3T that show you the location of these sprites (The Deoxys forms are different depending on the game)

And I've no idea where the base stats for these forms are located tbh.
