RSE Trainers
Not a lot to this. It wasn't too hard to do, so I downloaded all of the avaliable in RSE, pre-indexed. The chances are though, most of these sprites are already avaliable to be in ROM you are hacking (So I won't do a slideshow.) I ripped them, but from a ROM, so no credit needed. Credits to Corosis for the couple of intro sprites.
