A tilemap editor and creator for the Game Boy, Game Boy Color, and Game Boy Advance.
Source code: https://github.com/Rangi42/tilemap-studio
Tilemap Studio was designed with the Pokémon disassembly projects in mind, but it works with any GB, SGB, GBC, or GBA files.
If you have extracted a tilemap from a ROM, and optionally a tileset image, Tilemap Studio can open them and edit the tilemap. It supports palettes and tile attributes like X/Y flip and priority, and has editing features like undo/redo, flood fill, replacing or swapping tiles, etc. It supports multiple tilemap formats, including GBC or GBA tile attributes, SGB borders, and some Pokémon-specific compression formats.
If you have drawn a mockup of how a screen should look, the Image to Tiles tool can also generate a tilemap, tileset, and palette. The tileset and palette will be optimized to fit in the platform hardware limits, taking advantage of X/Y flip if possible.
