Overworld Data

Overworld Map

The overworld maps of the two main continents are on a tilemap, 64 wide by 75 tall spaces. Although the Death Mountain/Maze Island map is 64 x 41, there is a considerable amount of unused space at the end. This allows for a significant amount of vertical expansion.

The tilemaps are encoded in an RLE (Run Length Encoding) format. Each byte in these ranges codes for a horizontal strip of land. The most significant hex-digit (first hex digit) determines which of the sixteen land types will be used for the strip, while the second hex-digit controls the size of the strip, then add 1. In this latter case, the size will always be one space more than the digit used to program it. In other words, a seven will code for a strip eight spaces long, an F will code for a strip sixteen spaces long, a zero will code for a single space, etc.

Or in other words: 

xxxx.... - Tile Type
....xxxx - Length of strip (add 1 afterwards)

The tile values are assigned as follows:

  • 0 = Town
  • 1 = Cave
  • 2 = Palace
  • 3 = Bridge
  • 4 = Desert
  • 5 = Grass
  • 6 = Forest
  • 7 = Swamp
  • 8 = Graveyard
  • 9 = Plains (safe yellow ground)
  • A = Lava (when used in West Hyrule, touching an enemy will trigger a grassland battleground)
  • B = Mountain
  • C = Water
  • D = Walkable Water
  • E = Obstacle Stone
  • F = Black Devil (flute may not remove in West Hyrule)

Overworld in RAM

The compressed overworld map is copied to RAM to allow the game to modify the map. Tiles which can be modified (Roadblock, River Devil, Hidden location) must not be part of another horizontal strip, they must be their own byte, and have length 0. The overworld is stored in NES RAM at 0x7C00.

Rock Pointers

These control which byte in ram gets turned into a single rock (B0) after beating a palace. Keep in mind that the data here is RAM pointers, the base is 0x7C00, and the offset is how many bytes into the compressed map.

  • 0x479F - First palace (in west hyrule)
  • 0x47A1 - Second palace
  • 0x47A3 - Third palace
  • 0x47A5 - Fourth Palace (in Death Mountain, probably not used)
  • 0x1879F - Fifth Palace (in east hyrule)
  • 0x187A1 - Sixth Palace
  • 0x187A5 - Fourth Palace (in Maze Island)

Overworld Data Locations

  • 0x00506C - 0x00538C - Western Hyrule
  • 0x009056 - 0x00936F - Eastern Hyrule
  • 0x00665C - 0x0068F7 - Death Mountain and Maze Island (Used for Death Mountain)
  • 0x00A65C - 0x00A8F7 - Death Mountain and Maze Island (Used for Maze Island)


Area Pointers - General Information

There appear to be two layers of pointer coordinates for the overworld maps. The reason for this is still being researched, but it appears to give the game greater lattitude in distinguishing certain types of side-scrolling areas (single-entrance caves, single-screen fairy encounters, etc.) from others (palaces, towns, etc.). Failure to code new pointer coordinates with respect to their intrinsic HI/LOW status can result in junk areas being loaded, winding up in the original pointer location upon exiting an area, etc.

In both Eastern and Western Hyrule, the horizontal (X-axis) pointers range from 00 through 3F. Simultaneously, a second layer of X-axis pointers ranges from 40 through 7F. These "HI" values (always $40 more than their corresponding "LOW" values) tend to be used for towns and certain caves. Similarly, the vertical (Y-axis) pointers range from 1E to 68, top-to-bottom. The "HI" level pointers range from 9E to E8 (always $80 higher than their corresponding "LOW" values). The Y-axis "HI" values seem to be associated with towns, palaces and transition points to other maps.

In the following tables, each pointer will be identified as either "HI" or "LOW". Note that the HI/LOW status of a pointer on one axis has no relation to its status on the other; there are plenty of pointers with a mixed orientation such as HI-X / LOW-Y and vice versa.

† Because New Kasuto is hidden, the Y-value is stored as 00. The town can be "forced out of hiding" by replacing this value with D1. (The town still won't be visible on the overworld map.)

‡ Again, the hidden nature of the 6th Palace results in a stored Y-value of 00. To bring the palace out of hiding (making it eligible for re-positioning elsewhere), replace this value with E6.

Dwedit's documents (unsorted)

I just made a full document of what I know about Zelda 2's side-view areas, and copy-pasted it into datacrystal, I figure someone else can sort it out later. Haven't tested or verified it yet, so there may be a few mistakes. I just went by my level editor. 

Zelda 2 sideview information

Address convention:
I don't want to bother explaining NES memory pointers.
I'll be using addresses as they reside in NES memory.  $8000-$BFFF is where data rom banks are mapped in NES memory.
When I say $XXXX in rom bank Y, that means a file address of ($XXXX-$8000) + Y*$4000, + $10.  So a NES memory address $8123 on bank 4 means a .nes file address of $10133.

Sometimes pointers point to areas other than $8000-$BFFF, such as the SRAM area $6000-$7FFF.

--------------
Rom or Ram?
--------------
This game was originally an FDS game, so it relies on lots of data being writable.

Enemies are stored in SRAM starting at $7000
Compressed overworld maps are stored in SRAM starting at $7C00.

--------------
Number of Maps
--------------
Each area has 63 maps, 0-62, map #63 is an invalid map number indicating that the destination is outside.

---------
Rom Banks
---------
A "Rom Bank" is 16k (4000) bytes long.
Each rom bank has two sets of 63 maps, except for 3 and 5, which only have one set.

bank 1 contains west hyrule/death mountain
bank 2 contains east hyrule/maze island
bank 3 contains towns
bank 4 contains palaces 1,2,5, then palaces 3,4,6.
bank 5 contains the great palace

----------------------------
Map and Enemy Pointer Tables
----------------------------
Map pointers point to ROM in the $8000-$BFFF range.
Enemy pointers point to SRAM in the $7000-$7xxx range, this is so the game can keep track of defeated enemies.

Information for the second set of maps/enemies comes $1ADD later.

Enemy data for all 126 maps is copied from $88A0 to $7000.  (length unknown?)

For the first set of 63 maps:
$8523 - map pointers
$85A1 - enemy pointers

For the second set of 63 maps:
$A000 - map pointers
$A07E - enemy pointers

For the "behind this map" maps (1-7) specified by header byte 3 (there is no back map #0):
$8000 - map pointers


----------------------
Room connectivity data
----------------------
Begins at $871B, 4 bytes per entry
Begins at $A1F8 for second set of 63 maps

xxxxxx.. = Destination map number (63 to go outside)
......xx = Starting X coordinate on destination (times 256)

Order of bytes:
	Left exit
	Down exit
	Up exit
	Right exit

===================
Sideview Map Format
===================
----------------------
First 4 bytes (header)
----------------------

Things may vary, most of this info applies to overworld sideview maps, some may not apply for towns and palaces, some numbers may be different for those.

0 - Size of level in bytes, including header
1 - Flags
	x....... - Which Object Set - This determines which objects can appear on this map!
	.xx..... - Width of level (in screens, add 1)
	...x.... - ?
	....x... - "Grass", when set, adds grass tiles to map row #9
	.....x.. - "bushes", when set, adds bushes tiles to map row #10
	......xx - ?
2 - Ground Graphics / initial floor/ceiling position
The levels are made up of objects, and ground tiles.  This byte selects initial floor/ceiling position, and set of ground tiles to be used by the level.
	x....... - "no ceiling",  top 2 rows of the map are set to background tile, this overrides all
	.xxx.... - Sets which set of tiles assigned to the Ground tiles
		0 = cave
		1 = forest
		2 = lava/death water
		3 = swamp
		4 = sand/grass
		5 = volcano (cave with brighter wall)
		6 = North Castle
		7 = Cave with clear wall (rocks outside)
	....xxxx - Initial position of floor/ceiling
		0-7 = Floor at 2-9 (from bottom), Ceiling at 1 from top
		8-14 = Ceiling at 2-8 (from top)
		15 = Filled in with wall tile
3 - Palette and back tiles byte
	xx...... - Palette for sprites
		0 = black borders
		1 = dark colored borders
		2,3 = not used by game, give weird colors
	..xxx... - Background Palette
		0 = north castle
		1 = cave palette (dark without candle for overworld maps)
		2 = desert
		3 = grass
		4 = forest
		5 = swamp
		6 = graveyard
		7 = "water" palette
	.....xxx - Map to load behind map
		0 = nothing
		1 = clouds
		2 = forest (3 wide)
		3 = forest (4 wide)
		4 = forest (single tree)
		5 = Dead-end caves
		6 = long cave, dead end
		7 = ???
------------
Level bytes:
------------

0 - 
	xxxx.... - Y position
	....xxxx - Advance cursor X this many tiles after the object ("X space")
1 -
	xxxxxxxx - Object number
	If Object number = 15, and Y position < 13, then this is a 3 byte object (collectable item)
2 - (3 byte objects only)
	xxxxxxxx - For 3 byte objects only, object number (0-21, 22+ are not used)
	

Special Y posisitons:
	13 - Set new ground
		Sets the floor and ceiling to new values, just like header byte 2
		x....... - "no ceiling",  top 2 rows of the map are set to background tile
		.xxx.... - Not used, you can't change tiles for ground
		....xxxx - New position of floor/ceiling
			0-7 = Floor at 2-9 (from bottom), Ceiling at 1 from top
			8-14 = Ceiling at 2-8 (from top)
			15 = Filled in with wall tile
	14 - "Skip"
		Sets the cursor X directly to "x space" * 16.  Does not advance the cursor after this object as normal.
	15 - Extra objects, including lava and cactuses.  These have fixed-y coordinates.


-----------
Map Objects
-----------
This part really could be done much better, instead of hard-specifying everything, see how the game handles them, see what tiles it selects, see how it assembles the structures, etc.

Header:
Byte 0 - Length of enemy data
When selecting "Strong Enemy" for random overworld battles, advance that many bytes, data for "strong enemy" follows the first enemy set.  Non-random battles do not have "strong enemy" information

Bytes for enemy data:
0 -
	....xxxx = X coordinate (in tiles)
	xxxx.... = Y coordinate (in tiles)
		Y coordinate 0 maps to row 1, otherwise maps to row 2+x
1 -
	xx...... = Upper bits of X coordinate
	..xxxxxx = Enemy number (0-63)
