If you are planning on usem RPG Maker Vx Ace (Which I assume since you are asking this on this website) I belive your best shot is, as Archeia said, Crystal Engine, it is far from complete though if you want to check it out you can download it here: ģ. (There are allot of them being made with RPG maker titles, if you look arround the websites there are a few you can find, most use Pokemon Essencials as far as I can tell)Ģ.
You can make a pokemon game using RPG Maker if you don't make any money out of it.
