11. At this point we switch over to our text editor and open up "graphics_file_rules.mk" (this should be at the root of your expansion folder). here we will wind the rule for the file "graphics/pokenav/region_map/map.8bpp" and replace the number after "-num_tiles" with whatever our tile count is. Do note that this has to match exactly. Don't forget to save!

Inside your project folder, head to graphics/pokenav/region_map/ and copy the 3 files here.
14. We can now compile the project. Assuming every step was followed correctly, you should now be seeing your new region map in-game. **However, we aren't done yet. We still have the Pokédex map left to do.**

# 3. Formatting the Pokédex map
Since our palette and tileset have already been built, all we need to do now is to edit the actual tilemap.
1. If you closed Tilemap Studio inbetween, open it back up and drop your map.png in the small window to the left and map.bin to the bigger window on the right.
2. If you shifted the map during the creation of the region map, you will need to first shift it back. Since I shifted both X and Y by -2, I will need to now shift them by +2.

3. Go to Tools -> Resize... and reduce the height to 32.

4. Here's the tedious part. You can choose a column of tiles by holding down the right click and then copy that selection by left clicking.
We need to turn our map from this...

5. Go to Tilemap -> Save As... and save this as "region_map.bin"
6. Make a copy or rename your existing "map.png" and "map.pal" to "region_map.png" and "region_map.pal". You should now have 3 files for the Pokédex map:
* region_map.bin
* region_map.pal
* region_map.png
7. Copy these files to graphics/pokedex/ in your project folder.
8. In the "graphics_file_rules.mk" from earlier, search for the rule for "region_map.8bpp" and change the number after -num_tiles to the same we did earlier (in my case it was 240).
