Dragon Warrior II (NES)/RAM map

The following article is a RAM map for Dragon Warrior II (NES).

RAM Byte Address	Byte Size	Function	Details
0x0400 - 0x04ff	256	(Overworld) Something with status screens	This block of RAM seems to be a bitmap showing what overworld tiles are overlaid with status popups like health or a menu... but changing it seems to have no effect. This block of RAM seems to have a different purpose during battles.
0x05fb	1	Movement counter	Counts up as you move, unknown purpose
0x0600 - 0x0607	8	Inventory Slots	Each byte is one inventory slot. Values are as follows:
			0x00 = [Empty Slot] 0x01 = Bamboo Stick 0x02 = Magic Knife 0x03 = Wizard's Wand 0x04 = Staff of Thunder 0x05 = Club 0x06 = Copper Sword 0x07 = Chain Sickle 0x08 = Iron Spear 0x09 = Falcon Sword 0x0a = Broad Sword 0x0b = Giant Hammer 0x0c = Sword of Destruction 0x0d = Dragon Killer 0x0e = Light Sword 0x0f = Sword of Erdrick 0x10 = Thunder Sword 0x11 = Clothes 0x12 = Clothes Hiding 0x13 = Water Flying Cloth 0x14 = Mink Coat 0x15 = Leather Armor 0x16 = Chain Mail 0x17 = Gremlin's Armor 0x18 = Magic Armor 0x19 = Full Plate Armor 0x1a = Armor of Gaia 0x1b = Armor of Erdrick 0x1c = Leather Shield 0x1d = Shield of Strength 0x1e = Steel Shield 0x1f = Evil Shield 0x20 = Shield of Erdrick 0x21 = Mysterious Hat 0x22 = Iron Helmet 0x23 = Helmet of Erdrick 0x24 = Token of Erdrick 0x25 = Treasures 0x26 = Moon Fragment 0x27 = Charm of Rubiss 0x28 = Eye of Malroth 0x29 = Leaf of The World Tree 0x2a = Echoing Flute 0x2b = Mirror of Ra 0x2c = Dew's Yarn 0x2d = Magic Loom 0x2e = Cloak of Wind 0x2f = Gremlin's Tail 0x30 = Dragon's Bane 0x31 = Dragon's Potion 0x32 = Golden Card 0x33 = Lottery Ticket 0x34 = Fairy Water 0x35 = Wing of the Wyvern 0x36 = [Blank, If used it says you have taken Golden Card, Sell price is 2 Gold] 0x37 = Golden Key 0x38 = Silver Key 0x39 = Jailor's Key 0x3a = Watergate Key 0x3b = Antidote Herb 0x3c = Medical Herb 0x3d = Wizard's Ring 0x3e = Perilous 0x3f = [Blank, Use and nothing happens, Sell price is 2 Gold] 0x40 = [Equipped Blank] 0x41 - 0x63 = [Equipped Versions of 0x01 - 0x23]
0x0624 - 0x0625	2	Party Gold	Little-endian value. Total gold for your party is 255 * 0x0625 byte plus the 0x0624 byte. You can just set the 0x0625 byte to 0xff for a LOT of gold.
0x062d	1	Character 1: Status	Status as bitmask:
			Bit Mask Description --- ---- ----------- 0 1  ??? TBD 1 2  ??? TBD 2 4 On by default? TBD 3 8  ??? TBD 4 16  ??? TBD 5 32 Poisoned 6 64  ??? TBD 7 128 On by default? TBD
0x0633 - 0x0635	3	Character 1: Current XP	Little-endian value. Current total experience points for the first character. Careful, changing this will potentially result in a long process of level up messages after your next battle!
0x063b	1	Character 1: Current HP	Current hit points for the first character. Appears fine to set this higher than your max HP.
