Zoramine has further improved upon this here:
Being largely unhappy with how bare-bones FE8’s desert tileset is, chapter 15 for GFE1R and after @DerTheVaporeon mentioned that a large part of its graphics are from the cave tileset and unused, I set to work adding some of the missing elements to this tileset.
-Palm Tree on Grass
-Shadow Tiles for Floors
-Horizontal and Vertical Stairs + 1-Tile Floor Stairs
-House, Vendor, Armory, and Fort on Grass
-Arena on Sand and on Grass
-2 otherwise unused colors on last palette to make walls, doors, and stairs look correct
I also attempted to add the following, but they did not work mostly due to having to redraw them pixel by pixel and that turning out poorly:
-Other varieties of floor tiles
-Sand to Water transition tiles
-Added some grass cliffs at the request of @DerTheVaporeon (I’m apparently trying to see how many times I can ping him in a single post)
-Added @Feaw’s rocks, supplied by @dancer_A
-Broke the ballista letter tiles, oops
-Added more variations of stair tiles
-Added Sacae huts (this was an amazing idea that I never would have thought to do thank you @LordGlenn)
-Added side desert cliffs
-Fixed right side of large Sacae hut
Included in the download package is the raw graphics, TSA configuration, and palette, as well as the assembled tileset as its own image (see: the image at the top of this post) for use in your map editor of choice.
In the Tileset Palette Editor, navigate to the desert tileset. Click the import tile config button in the bottom left and import
BetterDesert.mapchip_config. Click the import image button and import
BetterDesert.png. In the Palette section, go to Palette 4 and click Clipboard. Paste this in and press Change:
Somewhere in your buildfile, place the
Tileset Installer.event. In the folder with that file, make a new folder called
Tileset. In the
Tileset folder, place
BetterDesertPalette.dmp. #include the Tileset Installer. It will write over the vanilla desert tileset, as it doesn’t change anything about that tileset it shouldn’t break any maps already using it.
Credit goes to @DerTheVaporeon for making a cave tileset installer whose structure I used for the installer here.
