FFIV TAY Tileset

It's really great!!! I wanted to edit the two overworld tilesets in my hack as well...but it's not a priority for now. I might incorporate your tileset in my hack...

I have a question: did you draw everything by hand in YY-CHR or were you able to copy/paste part of the tileset from a TAY bitmap or image?
So more generally is it possible to copy/paste from an external source in YY-CHR? I tried with a chrono trigger treasure chest (.bmp) from Gimp but it didn't work and I had to draw the opened and closed treasure chest manually. I want to do more tile editing but it's taking me a lot of tries before having something satisfaying.

If you set your palettes up right using the right sequence of colors, it's very possible to copy and paste tiles in which is what I did for some of these. I did do some spriting myself, like the mountains I heavily edited because they weren't originally one mountain like this tileset depicts.
