   Note that in the general scheme, we use D7, D6 and D5 for the bank number

-  by Activision only uses two banks.  Furthermore, the two banks it uses
-  are actually indicated by binary 110 and 111, and translated as follows:
+  (3 bits, so 8 possible banks), translated as follows:
 
-    binary 110 -> decimal 6 -> Upper 4K ROM (bank 1) @ $D000 - $DFFF
-    binary 111 -> decimal 7 -> Lower 4K ROM (bank 0) @ $F000 - $FFFF

-  Since the actual bank numbers (0 and 1) do not map directly to their
-  respective bitstrings (7 and 6), we simply test for D5 being 0 or 1.
-  This is the significance of the test '(value & 0x20) ? 0 : 1' in the code.
