This should probably go in the RM2K section.
Anyway, just 'coz it might be in wrong place doesn't mean I'm not gonna help. n_n You'll find many RPG Maker pokmon chipsets in the Resources thread in the RM2K subcategory. Even if you're not using RPG Maker, they can still be helpful, since many are PNGs which simple image-editors like Paint can read, so you can use a chipset for your own tileset. (Don't forget to give credit to whose chipset you use though!)
Hope I've been helpful! :P
