[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 data, based on the VRAM address of the data of dots 0-0 and dots 0-1.

Bitmap size: 512 dots horizontally x 256 dots vertically

Bitmap color number: 16 bits/dot (2048 colors, 32768 colors)
