Ok guys i LOVE your codes and im really glad i found this site i found just about everything i wanted here, and i am also putting together a Gamefaqs guide to these codes to hopefully allow easier access to them.
But there is one code that i would really really enjoy
Arceus as you know changes type as the plate he holds.
In the game code there exists a sprite of Arceus in every singe type imaginable, but there is one that cannot be accessed normally
This type is ??? [you can find a description on Bulbapedia]
Its kind of a Shadow type, with no real strengths or weaknesses, and I've only seen 2 or 3 attacks that have this type (one of which is in my Crystal game i am currently replaying)
What i would like, if possible, is a code that will at least visually make Arceus look like this, and if possible, change his Judgment attack to match, but even if he just looks like ??? type, ill be happy.
I dont have the proper equipment to hack my own codes, but you may try making a type modifier code for an Arceus in the first slot or something and see where it goes from there, if you find a code id be more than willing to test it before it is posted.
Thank you for your time and i hope you can find it. It should be a decent challenge!
