I've been lurking around the forum for a while now, checking out each thread here in the resource forum to see if I could find what I was looking for, but had no luck with it so I'm going to put down a request.
I noticed that Rm2k3Kid has an expansive collection of 4th Gen overworld sprites in the form of charsets for Rpg Maker XP. I also noticed that somewhere, someone mentioned that he converted these leading me to believe that they were first made in the form that Rpg Maker 2003 recognizes as there are programs that convert 2k3 to XP.
I can go and complie RM2k3 sets myself, but if the work has already been done and they exist somewhere out there, I could spend that time on actual game development and the custom sprite that are needed.
