Not at all. With a mapper every 16kB page can be switched on 0000, 4000,
8000 or C000. This is useful for example when you want to use a lot of
memory under BASIC. You can lift the bottom of your program to C000 (F676
if I remember correctly) and then use page 2 as data-area. With a 64kB
mapper this still gives you 48kB to use, in stead of the 16kB you would
have without a mapper.
