r&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Graphics data</PRE>
The Mode 7 screen data occupies all of the first 32 KB of VRAM: 16K is
for graphics data, and 16K is for the tile numbers.&nbsp; The tile map
format is simply the tile number with no other information, and takes one
byte.&nbsp; The dimensions of the tile map are 128x128 (=16384 bytes).&nbsp;
Unlike all other screen modes, the graphics data is a packed, linear format
and each color value directly indexes into CGRAM.
