    Hi everyone,

    I'm currently doing a Platinum hackrom with a brand new dex, including Gen5+ Mons, and some of them having several forms, like Aegislash or Darmanitan. But I also deleted some Pokémon like Deoxys or Shaymin, and they too have several forms. My first question is :
    "In which file are the alternate forms assigned to the basic Pokémon ?"
    because I do know how to edit their sprites, and even their stats, types, etc. but I do not know how to redirect them to a certain Pokémon.
    My second one, although not my priority, is :
    "Can I re-use the assembly code from BW and use it on Platinum to recreate Darmanitan's hidden ability, so that it can use Zen Mode directly in combat ? Same for Aegislash."
    I have very little knowledge in assembly, so re-writing the code a bit if it is needed may not be an easy task for me to do, but not impossible.

    If anything I said isn't that clear, feel free to tell me so I may explain exactly what I'm looking for.
    Thanks in advance for the help I will receive !
