Thats what i have now, but im trying to get 16 "chunks" instead of four.  visual:

00    
00      
vs
0000
0000
0000
0000

i feel that hving it in 4 scene (chunk) blocks is not good in basic (fg takes foreva).  this means every other room you go in, you have to sit and wait for it to be loaded.  16, or 4x4 blocking can be used to make a floor of a dungeon which is perfect because as you climb up a stairs or fall down a pit, during the "constrast animation" the loading will happen seemlessly.  Also, note that the 16 block style allows for a dungeon shape instead of just a square.  IE:
_00
00000
00000            (i had to use _ cuz space doesnt work here)
_00
_00
the upper right part of what could be a castle, possibly with stairs going up to a tower.  if you cannot see it, consider that each 0 represents a scene or chunk with its own 15x12 tile map.
before i dive back into any of this, i nd to reclaim some much needed RAM, based on the what response i get from Kev.

Edit:
15x12 of 8x8 sprites is what im using.
