[ 3 Scrolling Layers ]
|
|
||||||
|
|
||||||
There is memory for a huge layer, but the actual tilemap
|
|
||||||
is a smaller window (of fixed size) carved from anywhere
|
|
||||||
inside that layer.
|
|
||||||
|
|
||||||
Tile Size: 8 x 8 x 4
|
|
||||||
(later games can switch to 8 x 8 x 8, 16 x 16 x 4/8 at run time)
|
|
||||||
|
|
||||||
Big Layer Size: 2048 x 2048 (8x8 tiles) or 4096 x 4096 (16x16 tiles)
|
|
||||||
|
|
||||||
Tilemap Window Size: 512 x 256 (8x8 tiles) or 1024 x 512 (16x16 tiles)
|
|
||||||
|
|
||||||
The tile codes in memory do not map directly to tiles. They
|
|
||||||
are indexes into a table (with 0x200 entries) that defines
|
|
||||||
a virtual set of tiles for the 3 layers. Each entry in that
|
|
||||||
table adds 16 tiles to the set of available tiles, and decides
|
|
||||||
their color code.
|
|
||||||
|
|
||||||
Tile code with their msbit set are different as they mean:
|
|
||||||
draw a tile filled with a single color (0-fff)
|
|
||||||
|
|
||||||
|
|
||||||
[ 512 Zooming Sprites ]
|
|
||||||
|
|
||||||
The sprites are NOT tile based: the "tile" size can vary from
|
|
||||||
8 to 64 (independently for width and height) with an 8 pixel
|
|
||||||
granularity. The "tile" address is a multiple of 8x8 pixels.
|
|
||||||
|
|
||||||
Each sprite can be shrinked to ~1/4 or enlarged to ~32x following
|
|
||||||
an exponential curve of sizes (with one zoom value for both width
|
|
||||||
and height)
|
