EDIT: Question regarding SS/HG Hacking, including changing the type chart, and adding new 'mons instead of subbing out older ones

[HyruleShield]

Hello again everyone!

Before I begin, may I apologize for the many threads I've been creating lately.

Been getting immersed in the Pokehacking universe as of late, and it's awesome.

Alrigh, now that's that's out of the way...

#1: Can anyone tell me if it'd be possible to create an item that changes Arceus to his ??? typing form, along with his sig move?

If so, how should I go on about changing them?

#3: According to PowMikelan98, there are 107 empty slots to insert Pokemon data to. Is this true, and are they possible to edit? (Was it a Google Translate error?)

Again, if so, how should I go on about editing them?

#4: Is there any way to create new forms for a Pokemon? If so, how?

Thanks in advance everyone!
