Sorry for the late answer. Was busy with other stuff. Well your problem is simply that you mix 3rd and 4th gen graphics. The overworlds are 4th and the tilesets are 3rd gen. That is why it is overlapping. Try to use a gen4 tileset. Simply google for HGSS or DPP tileset and i am sure you will find some. Hope this helps and if you have questions don't hesitate to ask.
I was wrong. It does work. The other sheets I made I can't find. I'll have to remake the sheets. Should I add the shadow underneath the sheets I'm making (like it is for Gold / Ethan?) My friend was complaining that Ethan's head (and Alder, Lyra's heads were hitting things.)
Honestly that is a rather small complaint for the great looking sprites but once everyone has been scaled no body would be taller than anybody.
Man thanks for the sprite resizing tutorials. They helped a bunch. I do plan on having a release of all the sprites soon as I can. I'm still having trouble with the OW (as they become bigger than the doors they have to walk through.)
