Chip tiny.png The following article is a Notes Page for Pokémon Red and Blue.

False 'level' addresses

These are stored values that may change after switching a Pokémon up to a specific position in the party. The value for that process is updated after depositing and withdrawing the Pokémon into a box.

Pokémon ID

The RAM structure includes references Pokémon IDs. These do not match the Pokédex number in game. Instead, they correspond to the pokedex order listed in the ROM section, but with some numbers skipped:

Tileset headers

12 bytes per header, as follows :

1 byte  - Bank ID of blocks and tiles
2 bytes - Pointer to blocks
2 bytes - Pointer to tiles
2 bytes - Pointer to collision data
3 bytes - Up to 3 'talking-over tiles' tile numbers ("empty" slots are filled with $FF)
1 byte  - Grass tile ($FF if none)
1 byte  - Animation flag

Since the player moves on a 2x2 tile grid, the game checks the bottom-left tile of such a group for its properties (grass, talking-over...)

(Note : there's an inconsistency with this, the game uses the bottom-right tile to determine water, hence the Old Man Glitch)

Blocks

Maps are made up of 4x4 tile blocks, stored (how?)

A tile is 8x8 pixels, so a block is 32x32 pixels.

Tiles

Tiles are stored using the GB's format, and directly copied to VRAM.

Collision data

This is a pointer to a list of tile numbers over which the player can walk. Terminated with a FF byte.

Talking-over tiles

These are tiles which allow the player to talk to a person on the other side, such as the counters in the Pokémon Centers or Pokémarts.

Each tileset can have up to 3 talking over tiles. Use FF to fill the unused slots.

Grass tile

This is both a tile that will be rendered above sprites, and one where random "grass" encounters are possible.

Animation flag

This byte defines whether the tileset has animated tiles.

If the byte is zero, no animations take place. Otherwise, the water animation will be in effect, and if bit 0 is reset, the flower animation also will.

The water animation is done by rotating tile $14's pixels left and right. The flower animation, however, overwrites tile $03 with images stored in the ROM, at addresses $1F29, $1F29 and $1F39.


Map headers

This contains all the data (pointers count as data) to build the map.

1 byte  - Tileset ID
1 byte  - (Y Size) Map height
1 byte  - (X Size) Map width
2 bytes - Pointer to map data
2 bytes - Pointer to text pointers
2 bytes - Pointer to script
1 byte  - Connection Byte
11 bytes per connection - Connection data (No connections? Straight to object data!)
2 bytes - Pointer to object data

Tileset numbers

The tileset descriptions are copied from a document compiled by Cartmic, called "Pokémon Red Documents", which may help you with other stuff too.

Tileset No. Location in US R/B ROM Description
00 C7BE Outside
01 C7CA Red's House
02 C7D6 Pokémon Center
03 C7E2 Viridian Forest
04 C7EE Red's House (copy)
05 C7FA Gym
06 C806 Pokémon Center
07 C812 Gym (copy)
08 C81E House
09 C82A Museum
0A C836 Museum (copy)
0B C842 Underground Path
0C C84E Museum (second copy)
0D C85A S.S. Anne
0E C866 Vermilion Port
0F C872 Pokémon Cemetery
10 C87E Silph Co.
11 C88A Cave
12 C896 Celadon Mart
13 C8A2 Game Freak HQ
14 C8AE Lab
15 C8BA Bike Shop/Cable Center
16 C8C6 Cinnabar Mansion/Power Plant etc
17 C8D2 Indigo Plateau

NOTE: As you can see there's multiple copies of some tileset headers. They are literally copies.

If you're ROM hacking the game and want to add custom tilesets, you can delete copies to make room. However make sure that all maps that used the copy now use the original.

Map height (Y axis) & width (X axis)

Exactly that, the amount of blocks high and wide the map data is.

Map data pointer

You can use the GoldMap engine for hacking map data quite easily.

The map you walk around on and stuff is stored as block indexes. A single block consists of 4x4 tiles.

Pointer to text pointers

This points to a list of pointers. When the game attempts to display textbox #3, it will fetch the 3rd pointer in this list.

(Note : textbox #0 is hardwired to the START menu)

Pointer to script

Points to a function ran on each frame spent in this overworld (for example, not ran while a textbox is active)

If a map has a functionality you can't implement otherwise, check this out. You can sometimes find things like XY positions of Poké Balls and 1-time only Pokémon.

Connection mask

Note: If this value is $00 it is immediately followed by the object data pointer, no gap.

Connections can be obtained with binary masks:

connect_byte & (1 << 3) -> North
connect_byte & (1 << 2) -> South
connect_byte & (1 << 1) -> West
connect_byte & (1 << 0) -> East

List of values:

00 = No Connections
01 = East
02 = West
03 = West + East
04 = South
05 = South + East
06 = South + West
07 = South + West + East
08 = North
09 = North + East
0A = North + West
0B = North + West + East
0C = North + South
0D = North + South + East
0E = North + South + West
0F = North + South + West + East

Connection Data

Size can range from 0 to 44 bytes.

Probably the toughest thing to manipulate. This will certainly require planning, with no background distractions. (Unless an editor gets built that can hack the connections for RGBY.)

X/Y movement of connection

A X movement is how many map blocks there are to the left of one of your north/south connections.

A Y movement is how many map blocks there are above your west/east connection.

Structure

1 byte  - Map ID of connected map
2 bytes - Pointer to "connection strip"s upper-left block (Connected map)
2 bytes - Pointer to "connection strip"s upper-left block (Current map)
1 byte  - "Bigness"
1 byte  - Map Width
1 byte  - Y alignment
1 byte  - X alignment
2 bytes - Window

TODO : convert this block to wiki format.

===============================================================================
    #1 : Map Indexes
===============================================================================

Not included! Download UltraMap, the text file known as "RedEnglish.ini"
contains all the Map Indexes in decimal for R/B, which you'll obviously need
to convert to hex.

===============================================================================
 #2-#3 : "Connection Strip" Location
===============================================================================

The "connection strip" pointer -- points to the area of the connected map that
is visible when standing before you even enter it. Points to the upperleft
block of the "connection strip".
      * connection strip is always 3 blocks wide (E/W connection)
                                   3 blocks high (N/S connection)

===============================================================================
 #4-#5 : Current Map Position
===============================================================================

This points to the part of the current map (further up in RAM)
that the connection strips upperleft block is placed on the current map.

Sprites

Sprites are loaded when changing maps. However, there is a little subtlety : when traversing a map connection, the game assumes the correct sprite set is loaded, and doesn't reload sprites. (Hence glitchy sprites sometimes observed with Walk Through Walls).

The other occasion where sprites are loaded is when a text display is closed ; the game reloads sprites because the "walking" sprites are overwritten by font tiles.

Also, if there are no sprites (NPCs) the game doesn't reload sprite graphics.

How the game reloads sprites differs for "exterior" and "interior" maps.

Exterior maps

The game reads an entry from the table at 17A64, MapSpriteSets. If the entry is < $F0, the game uses the corresponding sprite set. Otherwise, it uses the corresponding split sprite set (see dedicated section).

Split sprite sets

Some exterior maps have two sprite sets, which depend on position.

Consider the entry read from MapSpriteSets. If the entry is $F8, that's Route 20 - a special case with a complex splitting. See its dedicated section.

The table maintains a table at 17A89, SplitMapSpriteSets, structured like so :

1 byte  - Split type (1 = East/West division, 2 = North/South division)
1 byte  - Split coordinate
1 byte  - Sprite set ID if coordinate <  split coordinate
1 byte  - Sprite set ID if coordinate >= split coordinate

The game reads an entry, indexed using (the byte read from MapSpriteSets AND $0F), and uses this sprite set.

Sea Route 20

Sea Route 20 has two sprite sets, $01 (West) and $0A (East). The only thing that differs from above is that the splitting is more complex.

If X coordinate < $2B
  Use set $01
End

If X coordinate >= $3E
  Use set $0A
End

If X coordinate >= $37
  If Y coordinate < $08
    Use set $0A
  Else
    Use set $01
  End
Else
  If Y coordinate < $0D
    Use set $0A
  Else
    Use set $01
  End
End

Interior maps

The game loads sprites by request, ie. the sprite tiles will be loaded as required by NPCs present on the loaded map.


Useful notes

Picture numbers

In order to get the ROM address of the tile relative to an entity (people/trainers/items), here is the formula to focus on the entity information:

 5 * $4000 + ($7b27 + 4 * (picture_id - 1)) % $4000

Then the entity information is stored according to this:

2 bytes - Tile address
1 byte  - Total size of tile data
1 byte  - Bank ID

So then, address = bankID * 0x4000 + tileAddr % 0x4000

Event displacement formula

$C6EF + (Map width) + (Map width + 6) * (Y offset) + (X offset)

Pointers

R/B Pointers to Map Headers: 0x01AE R/B Map Header Banks: 0xC23D R/B Pointer to Tileset Headers: 0xC767

Misc.

Maximum tileset size in VRAM: 6 rows of 16 tiles (9000-95FF)

Things that need adding:
------------------------
More information about tilesets, and info about what sprites get loaded for
which maps.

Updates:
--------
v1.6 by ISSOtm: Re-formatted the document, less ASCII and more wiki.
v1.5.1 by Sawakita: Fixed Tileset Header, completely (including last byte: Animation Flag)
v1.5 by phire: Completed Tileset Header, except for that last byte.
v1.4 Complete object data info with details about picture id.
v1.3 Edit by Cartmic to include almost completed tileset header information
     and Hat's further clarification on what the X/Y Movement of the Connection means.
v1.2: By ubitux: Add some information about connections and distinction between entities (People/Trainers/Items)
v1.11: Typo fixed by Hat: "01 = North" changed to "01 = East". Thanks to IIMarckus for pointing that out.
v1.1: By Hat, minor improvements.
v1.0: Original version typed up by Hat.

Main Credits (Structure Information):
-------------------------------------
  [Xeon]
    Wrote some stuff about Map Headers and Object Data.
    Which this document expands upon, a bit.

  [F-Zero] & [Tauwasser]
    Wrote a document (in German) explaining how GSC connection data is stored.
    RGBY connection data is stored almost the same way, it turns out, so
    that helped a great deal. All that is really different is the values you
    add the amount of blocks to.
