Tilemap Studio 
A tilemap editor for Game Boy, GBC, GBA, NDS, SNES, Genesis, or TG16 projects. Specifically meant to support the pret disassemblies like pokered, pokecrystal, and pokeemerald; as well as hacks including Polished Crystal, Red++, Orange, Prism, and many more.
Inspired by tools like Tilemap Creator, NTME, GSC Town Map Editor and Karteneditor, but implemented with C++ and FLTK, and with support for multi-platform tilemaps as well as Pokémon-specific formats.
Latest release: 4.0.1
Follow the steps in INSTALL.md to install the release copy of Tilemap Studio, or the longer instructions to build it yourself from source.
The example/ directory contains different formats of tilemaps and tileset graphics. In particular, pokecrystal/town_map_pokegear.png is a colored-in combination of tileset graphics from pokecrystal, useful for viewing any Town Map in a project based on it.
