Hello tongkexue, You can find the 47 tiles (Godot style) inside the folder "Fantasy Dreamland Reborn\Tilesets\Godot Auto Tiles."
I'm not entirely sure I understand your comment, could you clarify what you mean?
The regular tilesets I've created for GameMaker. While they can be used in other engines, they won't work by default in RPG Maker.
There is also a folder called "RPG Maker" that contains the tiles, including the A2 files, which should work as intended for RPG Maker.
