Barubary NPC Sprite Request

Oh I see
Yes that email should be enough to make a party, place characters in it, and set a party as the default one used for the menu and battles. So just make a second party and place whomever in there.
But don't worry about them being sent to the airship - as long as you don't follow up with a $3E to delete the characters originally in party 1, they'll still be in party 1.
So once you get all done with party 2 just write this out somewhere:
46, 01
And that'll make party 1 the default party. And the characters that were originally in party 1 will still be there.
But yeah how's the sprite coming along so far, Poco? :p Can't wait to see this all in action!
