Well, I edit tiles a lot too, but your tileset must be very filled.
My problem is the palletes, I need for the tileset 1 about 6 palletes or 5 and they're a lot just for one tileset hahahaha.I spend so much time editing the fucking tiles for use only 2 or 3 palletes.
I'm sure, you'll find a nice scripter if you make a topic. This place is full of nice hackers!
