its mroe to do with how efficiently you use the memory. Unused parts of an M9K cannot be reused. an M9K has 1bit x 9K locations (or other conjugations of that, like 9bits x 1k)

Ok.. so i must check the individual ROM's and try to make use of whole M9K blocks and try to avoid overflowing into a new M9K blocks. am i right ? i shall try it, thanks Tricky...
