Fix layout. The grey area is part of the display but only the area in the red rectangle should be used.

Pseudo-Static RAM used in the CD hardware, to store the fix tileset.

40x32 tiles made of 8x8 pixels.

Upper 2 and lower 2 rows out of the visible screen area.

16 colors per tile

Tiles can only use the first 16 palettes.

Base address in VRAM for the map: $7000, one word per tile (4 bits for the palette number, 12 bits for the tile number).

In MVS systems, the default fix tileset is stoed in the SFIX ROM.
