	Well, you could try using 'tiles'.  That is, divide the virtual
screen up into X by Y cells, each of which are a fixed size.  When you have
your cells, you can represent your virtual screen as an array of bytes/words
arranged as X by Y.  Each element in the array serves as an index into the
array of cells you have created.  Thus, you can assemble your entire screen by
blitting smaller cells into it.

	Faery Tale is done this way.  Faery Tale's virtual screen size is
HUGE.
