[Note 1]: The top left corner in the bitmap is dots 0-0, and from there to the right ~0-1, ~0-2, ~0-3,....
[Note 2]: The numbers in the bitmap are the VRAM addresses (hexadecimal) of each dot (2 dots) data, based on the VRAM address of dots 0-0 and dots 0-1 data.

Bitmap size: 1024 dots horizontally x 512 dots vertically

Bitmap color count: 4 bits/dot (16 colors)
