Data format:
GBA 4bpp

{
  u8 w; // real width = (w + 1) * 8
  u8 h; // real height = (h + 1) * 8
  u16 tiles[(w + 1) * (h + 1)]; // from bottom to top
}

So it's basically a "GBA tiles + 4bpp palettes" file, but with the rows reversed in bottom-to-top order, and the width and height prepended as bytes (so it can be max 256x256)?

Can you link to a couple example tilemap files and their corresponding tileset graphics?

Here is tileset, tilemap and palette:

Here is what it looks in the game:

Here is its C# implementation for reference:

Thanks! When I do implement it, this is how that one would look:
