I can't begin to tell you all what wonderful people you are.
I don't know what possessed me to wander haplessly into this forum and stumble upon this topic, but seeing all this has inspired me, and motivated me to try my hand at programming again. In two hours, I have made a picture-perfect replica of Pallet Town and Route 1, all basic functions of the game save for Pokemon encounters intact.
My time these days is extremely limited, so I don't know how fast I'll be able to work on this little pet project, but should I get farther along in it, perhaps I could work with some of you to allow for in-game interface swapping to one of these masterpieces you've designed. It will already be incredibly easy to work with you all as it is, since you obviously understand how tiles work.
