Sega Genesis Playfield Map Question:
« on: January 17, 2020, 04:25:37 pm »
OK, So I understand that the Sega Genesis Name table is like this:

pccvhnnnnnnnnnnn

    p = Priority flag
    c = Palette select
    v = Vertical flip
    h = Horizontal flip
    n = Pattern name

And that the pattern name is the upper 11 bits of the physical address of pattern
in video RAM.

But then the question is: Where are the final 5 bits for the pattern name? Where do I find it
Also, when it says upper 11 bits, does it mean the biggest 11 bits of the Pattern name?

Each 16 bits (2 bytes) is an entry. 11 bits for the tile ID, the remaining 5 bits used for the other stuff.
