High level idea

Tiled export format that is usable in Game Boy Advance projects.

GBA limitations

Layers

Tiled should export based on a desired target GBA mode and desired number of layers.

Merging layers

To support the desired mode & layers, Tiled layers must be merged.

• How do we let the user control this merging?

Palettes

Colour quantisation and palette allocation.
