Pokémon Gold and Silver/Unused Maps

Unused Olivine house
Gold, Silver, and Crystal have several early maps, but only a few can be considered complete. One of these is a "deleted" house located in Olivine City.

Two interactions can occur in this map. The first is a Rhydon. This Rhydon's walking data is wrong and shows a Clefairy during the walking animation.

RHYDON: Gugooh!

The other is a woman who says:

When my POKéMON got sick, the PHARMACIST in ECRUTEAK made some medicine for me.

Notice how she claims the pharmacy is located in Ecruteak City. In the final version of the game, the pharmacy was found in Cianwood City.

This is one of three complete unused maps in Gold and Silver (the other two forming the Safari Zone). Rather than delete the map completely, the programmers moved the "warp tile" (a means of accessing a map, usually placed on top of an image displaying a door or hole) to the upper‐left corner of Olivine City.

This map can be accessed with the following Gameshark codes:

Safari Zone
The Safari Zone was originally intended to re-appear in G/S, before being replaced with the bug-catching contest. All that remains of it is a single unfinished map and the gate house.

The map can be accessed using the Gameshark codes:

Alternatively, the Fuchsia City map can be patched to re-add the removed door. The warp and entrance gate still exist. The gate is an ordinary route house with nobody inside. This can be done by writing at ROM address  in all language versions in Gold, Silver and Crystal, or with the Game Genie code 3A6-0E9-19F.

The map has no exit, meaning anyone who saves inside is doomed forever. There are no events and no wild Pokémon, except for the default set in the water. Instead of the entrance house, there are some unused blocks, water fountains that use the water palette and hence its palette animation, and some blocks that have been deleted; they display tile, which is normally reserved for sprite/text graphics, as can be seen when pausing the game.

Like in Pokémon Red and Blue, the map uses the same music as Pokémon evolution.

Prototype Maps without Event Data
All addresses here are given for the Japanese v1.0 ROM, which coincide with Japanese v1.1, English v1.0 and German v1.0 offsets.

These prototype maps don't have entries in the global map table and no events for these maps have been found. For an explanation of the naming scheme of the map image files, see the notes on map and tileset naming scheme. For a detailed look at the early tileset for cities, see section Early Tileset.

Alph Ruin unsolved puzzle room
This map is completely unused. It was probably used by a programmer to get the coordinates for the blocks that are set via script in the rooms that are used by the game and have the solved riddle as default map layout.

Caves
Not much to talk about. One of these caves is probably a quick test map to see if the tileset and/or blockdata covers enough cases to build an actual cave.

Cinnabar Island laboratory
The map of the Pokémon Laboratory on Cinnabar Island were found completely in Gold and Silver. This might point to an early plan of including the laboratory as well.

Cities
There exists an early map for every city in Johto. Some of them show cut content.

Cut-outs
Most of the maps were cut out from sheets of several maps. Sometimes the programmer didn't assign the last row to be still a part of the map, since those rows would be border blocks anyway. Therefore it makes no visual difference. The data was left inside the ROM.


 * - Sprout Tower cut-out.
 * - Sprout Tower cut-out.
 * - Sprout Tower cut-out.
 * - MS Aqua inside cut-out.

Pokémon Center
It seems the original design for PokéCenters in this installment of Pokémon was to have the trading room separated from the main PokéCenter building. Probably so only special cities would have trade stations, making for a more natural disabling of the trading capabilities at the start of the game.

Rocket hideout
Either the Team Rocket hideout in Mahogany Town was supposed to be somewhat different, or there was another hideout presumably in Goldenrod City.

Sprout Tower
The Sprout tower used to be much bigger than its current form. However, floor number 4 seems to be missing from the unused maps.

Pewter Museum of Science
Evidence left in the ROM points to Pokémon RBGY's tileset not only getting a palette but also being used at one point during development. While no blockdata remains, the actual mapdata is still there and fits the Pewter Museum of Science perfectly. Without further ado, this is what they would have looked like in Pokémon Gold and Silver, using the individual blocks and tileset graphics of Pokémon RBGY with the associated colors from Pokémon Gold and Silver:

Undumped Map
The following map could not be dumped simply because no tileset fit it. Even though unused tile palette assignment data matching tileset from Pokémon RBGY have been found inside Pokémon Gold and Silver, RBGY's tileset 's blockdata, as well as the matched-up data from above, do not fit this map either.

- ??
The tileset and/or blockdata this map uses was probably merged with some other tileset's or altered beyond recognition. This map is likely 5×4 blocks. The general layout is as follows:

All values hexadecimal. Suggesting are plants,  is a row of bookshelves or a plain wall,  is floor,  is an entrance carpet,  might be just about anything, maybe a table or a chair.
