Basically the title spells it all.
This thread is dedicated to using RAM editing or even using Hex Editors
To allow unused Sprites to serve a purpose in the game.
Basically this thread can be considered an extended version and derivativeof here: http://projectpokemon.org/forums/showthread.php?t=1416
I decided to focus not just on Arceus, but on other unused sprites, if any known.
From what I know the currently unused pokemon sprites are as of the following:
Shellos: http://veekun.com/dex/pokemon/shellos/flavor
Gastrodon: http://veekun.com/dex/pokemon/gastrodon/flavor
??? Arceus: http://veekun.com/dex/pokemon/arceus/flavor
BETA Shaymin and Giratina: http://bulbapedia.bulbagarden.net/wiki/Platinum_beta
What we do know is for Arceus to Stay in Curse (???) type,
It's ability must not be MULTITYPE or it will transform back to normal type if not equipped with the correct item.
Using the offset of 0x00000040 for HEX editor,
The value for Curse Arceus is found to be at least, 4C - 4F.
(4D is my preference though).
I'm currently trying to get the Shellos and Gastrodon,
And on Platinum (using 0x00000040=4D) Gastrodon appears weird, Shellos unsucessful.
If anyone manages to come up with any values,
Note the value under which offset, and also which game (D/P or Pt)
My Current List in mind:
Gastrodon
Shellos
Shaymin (Pt)
Beta Origin Giratina (Pt)
Curse Arceus
Cherim (Sunny 'mode' without activating Sunny Day)
Substitute?
DP sprites in Pt
