	- Note that there's a 1-byte overrun when writing the inventory for
	  a new character, which causes the "hero learns first 8 battle
	  spells when registering the maximum number of characters" bug.
	  This is caused by a missing INY instruction after the INX at
	  $AF59 in bank 7 (in the code to store the initial inventory).
	  This bug may have been introduced during localization, since in
	  the Japanese version, all extra PCs start out with only Clothes
	  in their inventories, and the king of Aliahan gives the hero
	  weapons for the party.

(*) Maps $2F and $30 are the same map (the Assaram-Dhama tunnel); it has
    two entries for the convenience of the code to handle overworld-dungeon
    transitions.
(+) Map $81 is for the unreachable stairways behind the two NPCs in the
    small rooms in Brecconary (the place where the curse removal NPC was
    in the original Dragon Warrior).
