Well, I am turning this into a new project. I am going to compile all of the tiles of the Advance series, so the tileset will be huge. I should be done by the end of this week. So, here is a screenshot of the tileset in action. (I am also adding some custom tiles of my own.)
(This map is for a demonstration, not for an actual game)
Edit: Here is the tileset so far. Not much done except for trees, ground, signs, moving truck, and buildings.
There are two sets of trees because the grasses from R/S/E and FR/LG are different colors and styles. (The color from R/S and Emerald are the same, even though they are differently designed.)
Oh, and I did get Silon's Crimson Tears' permission to use his trees. If you use this tileset, give him credit.
