Hi, I was wondering if there is a program that I can use to create tilesets, not just tilemaps. I've tried Tilemap Studio, but I cannot create and export tilesets. I'm looking for a program like GBTD is for the gameboy. Thanks.

Can't say I have used GBTD, and most times I find myself replacing tiles in commercial games so tend not to have to do much from the ground up, however several of the tile editors will import PNG and BMP and their editing functionality can probably get things sliced up nicely and be able to shuffle things around pixel by pixel.

Yeah, but the various programs I've tried don't let me export the tilesets. I can verify this by checking the c file, which only has the tilemap data.

Tilesets are just raw image data so once converted to the proper GBA format (using a tool like Wingrit or Bimbo, both of which I have personally used but there are other tools, those may not be the best ones to use) you could even use an ordinary hex editor to inject the data into the ROM if you like. Although I used armips to automate it, but that requires writing asm-like scripts.
Tile Molester (which is what you would often use to extract images out of retro ROMs for modification) can also inject images it seems, so that might be the easiest. But if the new file is larger than the old one, you'll have to modify the pointers in the ROM manually.

Edit: Oh, for homebrew. I guess you just need the converted raw image data out of Wingrit, Bimbo or similar and you'll be able to import it into your code the same way you import other files, no need for Tile Molester or a hex editor.

Thanks, this is what I was looking for.

You can use Tiled in combination with my GBA export plugins and Grit or Usenti for GBA development. Tiled can export to png, and Grit/Usenti allows conversion to source data (automate that into your build script for example). My custom export plugins export the tilemap data from Tiled to formats that can be directly loaded into GBA VRAM. There might be easier ways, however this setup works great for me. Maybe I should look into adding image export options to Tiled for exporting to GBA image data directly, skipping the need for Grit/Usenti.. one day!
