Magic Spell Effect Pointers
from to ---- ---- 00E58 - 00E59 - Shield 00E5A - 00E5B - Jump 00E5C - 00E5D - Life 00E5E - 00E5F - Fairy 00E60 - 00E61 - Fire 00E62 - 00E63 - Reflect 00E64 - 00E65 - Spell 00E66 - 00E67 - Thunder
It's possible to alter the order in which Link "learns" magic spells by re-arranging the data from [$E58-$E67]. (For example, to make Thunder the first spell Link acquires, replace the data at [$E58-$E59] with that from [$E66-$E67]. Note, however, that the spell will still be under the first slot and named "Shield.")

Overworld Map Data
506C - 538C - West Hyrule 665C - 6942 - Death Mountain 9056 - 936F - East Hyrule A65C - A942 - Maze Island
The 4 Overworld maps are 64 tiles wide, and their respective heights are variable. Overworld data is encoded in an RLE (Run Length Encoding) format. Each byte codes for a horizontal strip of terrain, as follows:
xxxx .... - Length (add 1) .... xxxx - Type
Table of Tile Types:
0 Town 1 Cave 2 Palace 3 Bridge 4 Desert 5 Grass 6 Forest 7 Swamp 8 Graveyard 9 Road A Lava B Mountain C Water D Water (walkable) E Rock F Spider
Data Structure Example from West Hyrule (first four bytes starting at 0x506C):
BB DC 74 FC ...
- BB - 12 (B + 1) Mountain (B) Tiles
- DC - 14 (D + 1) Water (C) Tiles
- 74 - 8 (7 + 1) Desert (4) Tiles
- FC - 16 (F + 1) Water (C) Tiles
- BB DC 74 FC
Overworld in RAM
The compressed Overworld map is copied to Cartridge RAM to allow the game to modify the map. Data is stored between 0x7C00 and 0x7FFF.
These control which byte in Cartridge RAM gets turned into a single rock (0B) after completing a palace. Data is Cartridge RAM pointers, the base is 0x7C00, and the offset is how many bytes into the compressed map.
West Hyrule / Death Mountain 479F - Palace 1 47A1 - Palace 2 47A3 - Palace 3 47A5 - Palace 4 (in Death Mountain) East Hyrule / Maze Island 879F - Palace 5 87A1 - Palace 6 87A5 - Invalid pointer 87A7 - Palace 4 (in Maze Island)
Each area has 4 bytes that define various informations, like position on the Overworld, destination map number, destination world number, where Link starts in the side view mode, etc. Each byte is formatted as follows:
Byte 0 .xxx xxxx - Y position x... .... - External to this world Byte 1 (offset 3F bytes from Byte 0) ..xx xxxx - X position xx.. .... - On exit, appear at the location of area index minus this value (0-3) Byte 2 (offset 7E bytes from Byte 0) ..xx xxxx - Map number xx.. .... - Horizontal position to enter within map 0 = enter from the left 1 = enter at x=256 or from the right for 2 screens maps 2 = enter at x=512 or from the right for 3 screens maps 3 = enter from the right for 4 screens maps Byte 3 (offset BD bytes from Byte 0) ...x xxxx - World number ..x. .... - Forced enter from the right edge of screen .x.. .... - Pass through x... .... - Fall in hole

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.

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. Objects: (For Overworld sideview maps) 00001111 - 3 byte object (collectable) 0000xxxx - 16 different small objects xxxx.... - Object type ....xxxx - Size of object (1-16) Small objects: 00 = headstone 01 = cross 02 = angled cross 03 = tree stump 04 = stone table, ("stonehenge") 05 = locked door (always at Y position 8) 06 = sleeping princess Zelda 07 = sleeping princess Zelda 08 = Pit (extends to ground?) 09-0E = Cloud 0F = crash Big objects for Object set 0 0x = small objects 1x = crash 2x = forest ceiling, two high 3x = forest ceiling, two high 4x = curtains, two high 5x = forest ceiling, one high 6x = sword-destroyable blocks, one high 7x = horizontal pit, one high 8x = single weed, one high 9x = two weeds, one high Ax = north castle steps (background), one high Bx = background bricks, used in north castle and ruins, one high Cx = strip of volcano background, one high Dx = sword-destroyable blocks, one wide Ex = background tree trunk, one wide Fx = column, one wide Big objects for Object set 1 0x = small objects 1x = crash 2x = wide rock floor, two high 3x = wide rock ceiling, two high 4x = bridge, two high 5x = cave blocks, one high 6x = sword-destroyable blocks, one high 7x = bridge that falls apart, one high 8x = single weed, one high 9x = two weeds, one high Ax = horizontal pit, one high Bx = background bricks, used in north castle and ruins, one high Cx = strip of volcano background, one high Dx = sword-destroyable blocks, one wide Ex = tall rock floor, one wide Fx = stone spire Extra objects (Y position 15): 0x = crash 1x = crash 2x = Lava at bottom of screen, three high 3x = Cactus at Y position 9, grows upwards, one wide 4x = Cactus with stem at Y position 9, one wide, two high 5x = Elevator? 60-FF = crash Objects: (for towns) Small Objects: 00 = closed door with grass at bottom, 4 high 1 wide 01 = open door with grass at bottom 02 = open door with bricks at bottom 03 = open door with vertical bricks at bottom 04 = stonehenge 05 = chair 06 = ? 07 = cloud 08 = table 09 = bench 0A = cross 0B-0E = cloud 0F = crash Big objects for Object Set 0 0x = small objects 1x = crash 2x = cross hatched roof, two high 3x = gray vertical brick roof, two high 4x = green vertical brick roof, two high 5x = brick building, extends to ground 6x = white small brick building, extends to ground 7x = grass building, extends to ground 8x = white brick wall, extends to ground 9x = log building, extends to ground Ax = brown square windows, one wide, Two tall.
