This is a sub-page of Development:Pokémon Gold and Silver.

Hmmm...
To do:
Add subpages for the Nihon map and Johto map found in the internal source files and fill them out.

Nihon Map

Located in MAPSCN.LZH, which is in a backup of the MAPDATA folder. This map resembles the Honshu island of Japan and was first seen in the the Spaceworld 1997 demo.

Overworld

Spaceworld 97 Map 05/06/98 Map
PokemonGS Proto Overworld Map.png PokemonGS Proto 050698 Overworld Map.png

The overworld hasn't changed much since the Spaceworld '97 demo, aside from the introduction of the Magnet Train tracks in West, Newtype, and Kanto, as well as a whole lot of new signs sprinkled everywhere. An exhaustive list of all the changes is as follows:

  • The area which leads to Prince, north of Silent Hill, has been changed slightly, making the rock formation smaller and adding fencing.
  • On Route 1, the entrance and exit to Silent Hills are now denoted by grass patches, to make it clearer that they are loading zones.
  • The Trainers' School in Old City has a new exterior, and the sign which used to sit behind the school is now beside it.
  • The house on the route west of Old City has been replaced by a patch of grass. The sign closest to Old was also made part of the fencing, and a new sign has been added close to the gate house.
  • The layout of West now reaches further down to accommodate for the tracks, with some bushes and fences being removed in the upper half.
  • The route north of West had its southern layout slightly tweaked, and a sign has been added on both opposite sides of the route.
  • The League building and the Pokémon Center in Birdon swapped locations, and a sign has been added near the League Building and one of the houses.
  • Signs have been added in the routes north and east of Birdon.
  • The sign near Font's Pokémon Center was removed, and a new area that goes nowhere has been added south of town.
  • Signs have been added in the route west and north of Font. The fence type for the sea route north of South was also changed.
  • Trees have been added by the gate south of South, and so was a sign.
  • The bridges in High-Tech now lead to small islands within the city, leading to the city being squished vertically. A new house was also added, with a sign placed right beside it.
  • Three signs have been added on Route 15 (the route east of Newtype).
  • The layout of Newtype was tweaked to accommodate for the tracks, with a bridge being lowered, and the Pokémon League and the dojo being raised. A sign was also added near the League building, as well as near one of the NPC house.
  • Small islands with signs on them were added on the route leading to Sugar. A sign was also added near the Trainer School in Sugar itself.
  • The route east of Newtype had its western layout slightly tweaked, and a sign has been added.
  • A building has been added above the entrance to a cave on Route 18 (the route north-east of Newtype). This building is very likely the Power Plant, a set of interiors which goes unused in the Spaceworld 1997 demo. Regardless, a sign was also added near the cave entrance.
  • Signs were added on the routes east, north, and south of Blue Forest. A sign was also added on the route south of Stand.
  • Two signs were added on the route going from Silent Hill to Kanto.
  • A group of trees was shifted to the right in Kanto to make place for the path leading to the Magnet train building. A house near the Lavender Town stand-in was also moved down because it got in the way of the tracks.
  • Patches of grass have been added on the route east of Kanto. A sign was also added, and the gate building's incorrect roof was also fixed.

Interiors

Spaceworld '97 (Glitched) Later
SW97GLITCHEDMART.png SHOP01.MAP.png

A smaller version of the Poké Mart that seems to match the size of the glitched Marts in the Spaceworld '97 demo. It is possible that the small Poké Mart seen above was the intended appearance of the glitched Poké Mart.

Spaceworld '97 Later
PKMNGS-SpaceWorld97-CeladonGameCorner-MainBuilding.png SLOT.MAP.png

A set of bushes in the corner has been removed and a new set of stairs have been added to Celadon Game Corner.

STATION.MAP.png This is the early interior for the Magnet Train stations seen in the overworld.

The early Safari Zone present in the final game was added at this stage of development and left mostly unmodified.

Early Johto

Hmmm...
To do:
Red and Green SGB Maps for the Kanto maps. Assemble maps together.

Two early versions of a map that more closely resembles the final map exist. They appear in the following folders:

  • SOURCE\BACKUP\DMYMAP: The only other complete early map. Contains maps dated from October 6th, 1998.
  • SOURCE\MAPDATA\BACKUP: Contains a partial map that mostly contains Routes; some updated from the previous version, some not, and contains maps up to October 14th, 1998.

In addition, there are some more unused maps that can be found in SOURCE\MAPDATA, most of which are the unused versions of maps in the final game. The BACKUP folder also contains an early version of Johto dated after May 6th, 1998, indicating development had shifted to Johto after that date.

Towns and Cities

New Bark Town

DMYMAP (October 6th, 1998) Final (Unused, November 10th, 1998) Final (August 10th, 1999)
PokemonGSC SIZUOKA.MAP early.png PKMN GS Map2A 7AFB TS20.PNG PokemonGSC-New Bark Town.png

The buildings changed around a bit. In the DMYMAP version, Prof. Elm's house was moved to where the Pokémon Center was, and the neighbor's house was added. There's no water in this version, meaning that you could easily enter Route 27. The file name of the early map is SIZUOKA.MAP (Shizuoka), while the final map is WAKABA.MAP.

PokemonGSC SIZUDMY.FLD.png

There is also a variant of the map only found in the BACKUP folder. Named SIZUDMY.FLD, it removes the neighbor's house entirely. It was last modified on October 2nd, 1998.

Cherrygrove City

DMYMAP (October 6th, 1998) Final (Unused, December 24th, 1998) Final (June 4th, 1999)
PokemonGSC NAGOYA.FLD early.png PKMN GS Map2A 76C3 TS20.PNG PokemonGSC-Cherrygrove City.png

The DMYMAP version has some very interesting use of the pagoda tiles not seen in the final unused map, and lacks the gate between Route 29. It also contains a Gym. It's possible that it was the last Gym, akin to how Viridian City was the second city but had the final Gym. The file name of the early map is NAGOYA.FLD, while the final map is YOSHINO.MAP.

Violet City

DMYMAP (October 6th, 1998) Final (Unused, December 11th, 1998) Final (June 14th, 1999)
PokemonGSC NARA.FLD early.png PKMN GS Map2A 5659 TS1F.PNG PokemonGSC-Violet City.png

The arrangement of the city is completely different, even to the final unused map.

  • The Pokémon Center and Mart are approximately in about the same spot as the Gym is.
  • There are four houses, each seeming to represent a different element. While these houses were roughly kept, their positions were shifted around to be less symmetrical, and were opened up significantly.
  • Sprout Tower is in the place of the Ruins of Alph, and requires Cut to access. It is also visibly 9 floors tall, the same number of floors as the prototype Sprout Tower maps.

The early map file name is NARA.FLD, while the final map is KIKYOU.MAP.

Unused Town

DMYMAP (October 6th, 1998) Final (Unused, December 14th, 1998)
PokemonGSC SINGUU early.png PKMN GS Map2A 680D TS1F.PNG

The layout of the map was completely overhauled. Its file name is SINGUU.MAP (Shingu in Wakayama Prefecture).

Azalea Town

DMYMAP (October 6th, 1998) Final (Unused, December 10th, 1998) Final (July 13th, 1999)
PokemonGSC ARITA.FLD early.png PKMN GS Map2A 69F3 TS1F.PNG PokemonGSC-Azalea Town.png

It seems that Game Freak were unsure whether or not to put a Gym here, as it was removed in the later version only to then be added back in the final. The file name is ARITA.FLD (Arida in Wakayama Prefecture), while the final map is HIWADA.MAP.

Goldenrod City

DMYMAP (October 6th, 1998) Final (Unused, November 2nd, 1998) Final (August 3rd, 1999)
PokemonGSC OSAKA.FLD early.png PKMN GS Map2A 5D07 TS20.PNG PokemonGSC-Goldenrod City.png

While the DMYMAP version doesn't seem to differ much from the final unused map, it has some notable differences. For one, the gates use the standard roofs, and are missing the exit carpets. Also, while the structure of the Radio Tower appears to be similar, the tiles that make it up were shuffled around quite a bit.

The file name of the early version is OSAKA.FLD, while the final map is KOGANE.MAP.

Ecruteak City

Spaceworld '97 Early (October 6th, 1998) Final (July 15th, 1999)
Old City SWGS.png PKMN GS Map2A 688B TS1F.PNG PokemonGSC-Ecruteak City.png

The DMYMAP version is identical to the unused version found in the final game. The file name of the early version is KYOTO.FLD, while the final map is ENZYU.MAP.

Olivine City

DMYMAP (October 6th, 1998) Final (August 22nd, 1999)
PKMN GS Map2A 7993 TS20.PNG PokemonGSC-Olivine City.png

The DMYMAP version of Olivine City is identical to the version found unused in the final. The file name is KOUBE.FLD (Kobe), while the final map is ASAGI.MAP.

Mahogany Town

DMYMAP (October 6th, 1998) Final (Unused, December 15th, 1998) Final (April 19th, 1999)
PokemonGSC IGA.FLD early.png PKMN GS Map2A 71AF TS1F.PNG PokemonGSC-Mahogany Town.png

Whereas the unused early map in the final game is more-or-less the same in layout to the final game, the DMYMAP version is completely different. It's unclear whether the traditional pagoda house was originally the Gym or the entrance to Team Rocket HQ. The file name is IGA.FLD, while the final map is CHOUZI.MAP.

Lake of Rage

DMYMAP (October 6th, 1998) Final (Unused, December 15th, 1998) Final (June 9th, 1999)
PokemonGSC BIWAKO.FLD early.png PKMN GS Map2B 4180 TS1F.PNG PokemonGSC-Lake of Rage.png

Another case where the location's landmarks flip-flopped. Despite being earlier, the DMYMAP version is more similar to the final, and is only missing the Fishing Guru's house. The file name is BIWAKO.FLD (Lake Biwa), while the final map is IKARI.MAP.

Blackthorn City

The early unused maps are identical to the ones found in the final game.

Pallet Town

One of the few maps that is completely identical to the final map.

Viridian City

Generation I DMYMAP (October 6th, 1998) Final (June 23rd, 1999)
File:PokeGen1-Viridian City.png PokemonGSC TOKIWA.FLD early.png PokemonGSC ViridianCity.png

Closer to the Generation I version than the final map. Aside from the entrance to Route 1 being shifted, it's identical to the Gen I map. The early version's file name is TOKIWA.FLD, and the final is TOKIWA.MAP.

Pewter City

Generation I DMYMAP (October 6th, 1998) Final (August 21st, 1999)
File:PokeGen1-Pewter City.png PokemonGSC NIBI.FLD early.png PokemonGSC PewterCity.png

The Pewter Museum of Science is still open! Evidence exists in the final game that this one would originally have been included in the game. The early version's file name is NIBI.FLD, and the final is NIBI.MAP.

Cerulean City

Generation I DMYMAP (October 6th, 1998) Final (August 12th, 1999)
PokeGen1-Cerulean City.png PokemonGSC HANADA.FLD early.png PokemonGSC CeruleanCity.png

Surprisingly, Cerulean Cave is still here, suggesting that it might have returned at one point, as is the robbed house. The early version's file name is HANADA.FLD, and the final is HANADA.MAP.

Lavender Town

Generation I DMYMAP (October 6th, 1998) Final (June 22th, 1999)
File:PokeGen1-Lavender Town.png PokemonGSC SION.FLD early.png PokemonGSC LavenderTown.png

The layout in the DMYMAP version is identical to Generation I, and as a result the Soul House is missing. The early version's file name is SION.FLD, and the final is SION.MAP.

Vermilion City

Generation I DMYMAP (October 6th, 1998) Final (August 10th, 1999)
File:PokeGen1-Vermilion City.png PokemonGSC KUTIBA.FLD early.png PokemonGSC VermilionCity.png

Vermilion City is the first example of something that is common in the Kanto maps: Many of them actually combine surrounding Routes into a single map. In this case, Vermilion City's DMYMAP version also contains Route 6. The early version's file name is KUTIBA.FLD, and the final is KUTIBA.MAP.

Celadon City

Generation I DMYMAP (October 6th, 1998) Backup (October 14th, 1998) Final (May 31st, 1999)
File:PokeGen1-Celadon City.png PokemonGSC TAMAMUSI.FLD early.png PokemonGSC TAMAMUSI.FLD later.png File:PokemonGSC CeladonCity.png

More merged maps. Celadon City's DMYMAP version contains both Routes 7 and 16 in the map. As with the other gates to Saffron City, they're missing in the DMYMAP version. The backup version contains it, but only half of it is included on Route 7, unlike the final map. All early versions lack the entrance to Cycling Road and the Celadon Café.

The early version's file name is TAMAMUSI.FLD, and the final is TAMAMUSI.MAP.

Fuchsia City

Generation I DMYMAP (October 6th, 1998) Backup (October 14th, 1998) Final (August 21st, 1999)
File:PokeGen1-Fuchsia City.png PokemonGSC SEKITIKU.FLD early.png PokemonGSC SEKITIKU.FLD later.png PokemonGSC FuchsiaCity.png

Another example of merged maps. Fuchsia City's DMYMAP version also contains Route 18, which also lacks the exit to Cycling Road. Strangely, the backup version has half of the exit, but the backup version of Route 17 does not have the other half of it. The gate to Route 15 is farther out and lacks an exit carpet, and the gate to Route 19 is still missing. Both early maps are closer to the Generation I map, and even contain the zoo and Safari Zone entrance.

The early version's file name is SEKITIKU.FLD, and the final is SEKITIKU.MAP.

Saffron City

Generation I DMYMAP (October 6th, 1998) Backup (October 14th, 1998) Final (August 22nd, 1999)
File:PokeGen1-Saffron City.png PokemonGSC YAMABUKI.FLD early.png PokemonGSC YAMABUKI.FLD later.png PokemonGSC SaffronCity.png

For whatever reason, all of the gates in the DMYMAP version of Saffron City are missing. They were added back in the backup version, but they are all missing exit carpets. Both early maps also lack the Copycat's house and the Magnet Train station. The early version's file name is YAMABUKI.FLD, and the final is YAMABUKI.MAP.

Cinnabar Island

Generation I DMYMAP (October 6th, 1998) Final (July 1st, 1999)
File:PokeGen1-Cinnabar Island.png PokemonGSC GUREN.FLD early.png PokemonGSC CinnabarIsland.png

The DMYMAP version is identical to Generation I, before the volcano erupted. The early version's file name is GUREN.FLD, and the final is GUREN.MAP.

Routes

Route 29

DMYMAP (October 6th, 1998) PokemonGSC ROAD129.FLD early.png
Final (August 1st, 1999) PokemonGSC Route29.png

The first Route! It starts a trend that most of the early Johto routes have: very linear, and very rarely any points where you need to step into tall grass to progress. The designers also make some weird patterns with the Headbutt trees on many of them. The early version's file name is ROAD129.FLD, and the final is ROAD129.MAP.

Earlier (October 13th, 1998) Later (October 14th, 1998)
File:PokemonGSC ROAD129.FLD alternate.png File:PokemonGSC ROAD129B.MAP.png

There are also these intermediate maps. These ones still seem to have the concept of the Silent Hills dungeon on the first Route as seen in the Spaceworld '97 demo. Interestingly, the earlier map has more tall grass than the later one. The earlier one is the backup version of Route 29, as ROAD129.FLD, and the later one is in the MAPDATA folder as ROAD129B.MAP.

Route 30

DMYMAP (October 6th, 1998) Final (July 18th, 1999)
PokemonGSC ROAD130.FLD early.png PokemonGSC Route30.png

And so continues the trend. Nothing really interesting aside from the river, just a straight line. Mr. Pokémon's house isn't on this Route in the DMYMAP version. The early version's file name is ROAD130.FLD, and the final is ROAD130.MAP.

Route 31

DMYMAP (October 6th, 1998) PokemonGSC ROAD131.FLD early.png
Final (July 18th, 1999) PokemonGSC Route31.png

And here's where Mr. Pokémon's house (presumably) is in the DMYMAP version. Otherwise, just a 90-degree turn and a straight line. The early version's file name is ROAD131.FLD, and the final is ROAD131.MAP.

Route 32

DMYMAP (October 6th, 1998) Final (July 9th, 1999)
PokemonGSC ROAD132.FLD early.png PokemonGSC Route32.png

There's a whole lot more water here. The Ruins of Alph and Union Cave are seemingly missing.

Route 33

DMYMAP (October 6th, 1998) Final (July 6th, 1999)
PokemonGSC ROAD133.FLD early.png PokemonGSC Route33.png

Instead of connecting Route 32 to Azalea Town, the DMYMAP version of Route 33 connects the unused town in the final game to Azalea Town. The early version's file name is ROAD133.FLD, and the final is ROAD133.MAP.

There is also another version that contains a dungeon between the two towns. This can be found in many places. In the backup version, it is ROAD133.FLD, and can be found in the MAPDATA folder as ROAD133B.MAP and HILLCEL.MAP. It was last modified October 13th, 1998.

Route 34

DMYMAP (October 6th, 1998) Final (July 13th, 1999)
PokemonGSC ROAD134.FLD early.png PokemonGSC Route34.png

Amazingly enough, this Route actually requires you to step in some tall grass! The Day Care and Cooltrainer secret hideout are not present yet. The early version's file name is ROAD134.FLD, and the final is ROAD134.MAP.

Route 35

DMYMAP (October 6th, 1998) Final (July 9th, 1999)
PokemonGSC ROAD135.FLD early.png PokemonGSC Route35.png

DMYMAP Route 35 revolutionizes the straight line design of Routes by slightly winding a bit. The only things worth noting are the lack of the National Park entrance and the missing exit carpet from the Goldenrod gate. The early version's file name is ROAD135.FLD, and the final is ROAD135.MAP.

Route 36

DMYMAP (October 6th, 1998) PokemonGSC ROAD136.FLD early.png
Final (July 9th, 1999) File:PokemonGSC Route36.png

A strangely symmetrical lake connects Goldenrod City to Ecruteak and Violet City. The early version's file name is ROAD136.FLD, and the final is ROAD136.MAP.

Route 37

DMYMAP (October 6th, 1998) Final (August 23rd, 1999)
PokemonGSC ROAD137.FLD early.png PokemonGSC Route37.png

Compared to the Routes so far, Route 37 is closer to the final than any of them. The early version's file name is ROAD137.FLD, and the final is ROAD137.MAP.

Route 38

DMYMAP (October 6th, 1998) PokemonGSC ROAD138.FLD early.png
Final (July 9th, 1999) PokemonGSC Route38.png

The three-path layout of the final Route is in place, but there's little to no reason to not stick to the middle path. The gate to Ecruteak City is missing. The early version's file name is ROAD138.FLD, and the final is ROAD138.MAP.

Route 39

DMYMAP (October 6th, 1998) Final (August 26th, 1999)
PokemonGSC ROAD139.FLD early.png PokemonGSC Route39.png

The farm space is drastically smaller, the barn is a separate building instead of being right next to the farmhouse, and there's a pond that was removed in the final map. The early version's file name is ROAD139.FLD, and the final is ROAD139.MAP.

Route 40

DMYMAP (October 6th, 1998) Final (July 8th, 1999)
PokemonGSC ROAD140.FLD early.png File:PokemonGSC Route40.png

Route 40 connects directly south to Olivine City, so no space in the DMYMAP version is used for the beach. The early version's file name is ROAD140.FLD, and the final is ROAD140.MAP.

Route 41

DMYMAP (October 6th, 1998) Final (June 4th, 1999)
PokemonGSC ROAD141.FLD early.png File:PokemonGSC Route41.png

Instead of connecting to Cianwood City, Route 41 connects back to Goldenrod City. The Whirl Islands are nowhere to be seen. The early version's file name is ROAD141.FLD, and the final is ROAD141.MAP.

Route 42

DMYMAP (October 6th, 1998) PokemonGSC ROAD142.FLD early.png
Final (June 9th, 1999) File:PokemonGSC Route42.png

Route 42 is another straight line, and doesn't have Mt. Mortar or any bodies of water to vary things up at all. The early version's file name is ROAD142.FLD, and the final is ROAD142.MAP.

Route 43

DMYMAP (October 6th, 1998) Final (July 9th, 1999)
PokemonGSC ROAD143.FLD early.png PokemonGSC Route43.png

Route 43 is somewhat similar to the final map. The vertical stretches of tall grass were made shorter, and (given that it's missing on the Lake of Rage DMYMAP version) the house might be the house of the Fishing Guru. The early version's file name is ROAD143.FLD, and the final is ROAD143.MAP.

Route 44

DMYMAP (October 6th, 1998) PokemonGSC ROAD144.FLD early.png
Final (August 10th, 1999) PokemonGSC Route44.png

Layout is more-or-less complete. The final map just has more stuff added around the ponds. The Ice Path is completely missing in the DMYMAP version, however. The early version's file name is ROAD144.FLD, and the final is ROAD144.MAP.

Route 45

DMYMAP (October 6th, 1998) Final (August 16th, 1999)
PokemonGSC ROAD145.FLD early.png PokemonGSC Route45.png

Structurally, the layout is identical to the final map. The only difference is the lack of tall grass, dirt, and entrance to Dark Cave. The early version's file name is ROAD145.FLD, and the final is ROAD145.MAP.

PKMN GS rpgamer 1999-11-08 screenshot 3.gif

This version of the map also appeared in the May 1999 issue of CoroCoro magazine.

Route 46

DMYMAP (October 6th, 1998) Final (July 9th, 1999)
PokemonGSC ROAD146.FLD early.png PokemonGSC Route46.png

Also largely similar to the final. There are fewer ledges, no entrances to Dark Cave, and there's no gate between it and Route 29. The early version's file name is ROAD146.FLD, and the final is ROAD146.MAP.

Route 27

DMYMAP (October 6th, 1998) PokemonGSC ROAD127.FLD early.png
Final (August 7th, 1999) PokemonGSC Route27.png

The DMYMAP version is interesting, as there's nothing that seems to block the player from going this way at the start, and heading north directly leads to Route 28. Tohjo Falls is missing, and the house of the person who gives the Sandstorm TM is just kind of placed in the middle of the map. The early version's file name is ROAD127.FLD, and the final is ROAD127.MAP.

Route 26

DMYMAP (October 6th, 1998) Final (August 20th, 1999)
PokemonGSC ROAD126.FLD early.png PokemonGSC Route26.png

The DMYMAP version lacks the rest house that the final map has. The house seen in this early map would have been a haunted house, a location which was ultimately scrapped, and whose spot on the map was ultimately replaced with the Week Siblings' house. The early version's file name is ROAD126.FLD, and the final is ROAD126.MAP.

Route 1

Generation I DMYMAP (October 6th, 1998) Final (August 21st, 1999)
File:PokeGen1-Route 1.png PokemonGSC ROAD1.FLD early.png PokemonGSC Route1.png

The flowers to the left of the exit to Viridian City were moved from below the ledge to above it. The early version's file name is ROAD1.FLD, and the final is ROAD1.MAP.

Route 2

Generation I DMYMAP (October 6th, 1998) Final (August 21st, 1999)
File:PokeGen1-Route 2.png PokemonGSC ROAD2.FLD early.png PokemonGSC Route2.png

The north exit of the side gate is missing the exit carpet. The early version's file name is ROAD2.FLD, and the final is ROAD2.MAP.

Route 3

Generation I File:PokeGen1-Route 3.png
Backup (October 14th, 1998) PokemonGSC ROAD3.FLD early.png
Final (October 15th, 1998) PokemonGSC Route3.png

One hole in the first ledge on the Route was removed. The early version's file name is ROAD3.FLD, and the final is ROAD3.MAP.

Route 4

Generation I File:PokeGen1-Route 4.png
Backup (October 14th, 1998) PokemonGSC ROAD4.FLD early.png
Final (August 29th, 1999) PokemonGSC Route4.png

The path that leads to Cerulean Cave in Generation I is still here, as Cerulean Cave is also present. The early version's file name is ROAD4.FLD, and the final is ROAD4.MAP.

PokemonGSC ROAD34.MAP combinedver.png

ROAD34.MAP is a variant map that combines Routes 3 and 4 into a single map. Both parts of it are similar to the backup versions', but some changes were made, such as the dirt around the Mt. Moon exit sign being removed. It was last modified on October 14th, 1998.

Route 5

Generation I DMYMAP (October 6th, 1998) Backup (October 14th, 1998) Final (July 30th, 1999)
File:PokeGen1-Route 5.png PokemonGSC ROAD5.FLD early.png PokemonGSC ROAD5.FLD later.png PokemonGSC Route5.png

The first of the four Routes connected to Saffron City. In the DMYMAP version, there are no gates between Saffron City and the surrounding Routes. The backup version is closer to the final, but has the roof of the gate on the Route itself, instead of being entirely in the Saffron City map. It is also missing the exit carpet. The early version's file name is ROAD5.FLD, and the final is ROAD5.MAP.

Route 8

Generation I File:PokeGen1-Route 8.png
DMYMAP (October 6th, 1998) PokemonGSC ROAD8.FLD early.png
Backup (October 14th, 1998) PokemonGSC ROAD8.FLD later.png
Final (August 29th, 1999) PokemonGSC Route8.png

There are more posts on the right side of the Route, and the flowers are arranged differently. This gate is only partially on Route 8 in the backup version, but was moved to be entirely on Route 8 in the final. The early version's file name is ROAD8.FLD, and the final is ROAD8.MAP.

Route 9

Generation I File:PokeGen1-Route 9.png
DMYMAP (October 6th, 1998) PokemonGSC ROAD9.FLD early.png
Backup (October 14th, 1998) PokemonGSC ROAD9.FLD later.png
Final (October 27th, 1998) PokemonGSC Route9.png

Mostly identical to the final. The Pokémon Center only has the roof on Route 9 in the final. Strangely enough, while the DMYMAP versions of most maps have Kanto dungeons that aren't in the final, Rock Tunnel - a dungeon that is in the final - isn't accessible. The early version's file name is ROAD9.FLD, and the final is ROAD9.MAP.

Route 10

South File:PokeGen1-Route 10South.png PokemonGSC ROAD10 South early.png PokemonGSC Route10South.png

On the north side, the Power Plant is accessible without needing Surf, and the sign for it is in a different position. There's also a dock(?) under the Power Plant. On the south side, there are some different ground tiles used, and some of the mountain behind Lavender Radio Tower was removed. The north map's file name is ROAD10_1.MAP, and the south map's file name is ROAD10_2.MAP.

A variant of the map exists as ROAD10.MAP, which combines both the north and south sides into one map. The wall between the two sides of Route 10 was removed to accomodate for Rock Tunnel being inaccessible. It was last modified on October 14th, 1998.

Route 11

DMYMAP (October 6th, 1998) PokemonGSC ROAD11.FLD early.png
Final (June 22nd, 1999) PokemonGSC Route11.png

The sign is missing on the west side. The early version's file name is ROAD11.FLD, and the final is ROAD11.MAP.

Route 12

Generation I DMYMAP (October 6th, 1998) Final (July 28th, 1999)
File:PokeGen1-Route 12.png PokemonGSC ROAD12.FLD early.png PokemonGSC Route12.png

The ground on various points of the bridge was changed to flowers, and there is tall grass at the bottom of the Route as in Gen I. The early version's file name is ROAD12.FLD, and the final is ROAD12.MAP.

Route 13

DMYMAP (October 6th, 1998) PokemonGSC ROAD13.FLD early.png
Final (June 23th, 1999) PokemonGSC Route13.png

A sign was removed by the cut tree. The early version's file name is ROAD13.FLD, and the final is ROAD13.MAP.

Route 14

Another rare map that's identical to the final map.

Route 15

Backup (October 14th, 1998) PokemonGSC ROAD15.FLD later.png
Final (October 20th, 1998) PokemonGSC Route15.png

As with Saffron City, the DMYMAP version is completely missing the gate between Fuchsia City and Route 15. The backup version, meanwhile, is only missing the exit carpet for the gate. The early version's file name is ROAD15.FLD, and the final is ROAD15.MAP.

Route 17

Generation I DMYMAP (October 6th, 1998) Final (February 26th, 1999)
File:PokeGen1-Route 17.png PokemonGSC ROAD17.FLD early.png PokemonGSC Route17.png

For starters, while the Gen I map was entirely covered in flowers, the DMYMAP version is completely devoid of flowers. The final map added some back in. More importantly, the exit gate for Cycling Road is missing. The early version's file name is ROAD17.FLD, and the final is ROAD17.MAP.

Route 19

Generation I DMYMAP (October 6th, 1998) Backup (October 14th, 1998) Final (July 10th, 1999)
File:PokeGen1-Route 19.png PokemonGSC ROAD19.FLD early.png PokemonGSC ROAD19.FLD later.png PokemonGSC Route19.png

The last major gate in the game. The DMYMAP version has a significantly shorter beach, and while the backup version's is the same size as the final, the ledges are higher up on the beach. The gate also is only a small house. The early version's file name is ROAD19.FLD, and the final is ROAD19.MAP.

Route 20

Generation I File:PokeGen1-Route 20.png
DMYMAP (October 6th, 1998) PokemonGSC ROAD20.FLD early.png
Final (July 10th, 1999) PokemonGSC Route20.png

The DMYMAP version is much closer to the Gen I version, only a bit shorter. The entrance to the other Seafoam Island is still open, which makes sense as Blaine's Gym is still present on Cinnabar Island at this point. The early version's file name is ROAD20.FLD, and the final is ROAD20.MAP.

Route 21

Generation I DMYMAP (October 6th, 1998) Final (June 21st, 1999)
File:PokeGen1-Route 21.png PokemonGSC ROAD21.FLD early.png PokemonGSC Route21.png

The northern dock on Cinnabar Island is still present in the DMYMAP version, of course, as Cinnabar hasn't erupted in this version of the map. The early version's file name is ROAD21.FLD, and the final is ROAD21.MAP.

Route 22

Generation I File:PokeGen1-Route 22.png
DMYMAP (October 6th, 1998) PokemonGSC ROAD22.FLD early.png
Final (June 2nd, 1999) PokemonGSC Route22.png

The DMYMAP version is identical to the Gen I map! The early version's file name is ROAD22.FLD, and the final is ROAD22.MAP.

Route 25

Generation I File:PokeGen1-Route 25.png
DMYMAP (October 6th, 1998) PokemonGSC ROAD2425.MAP early.png
Final (August 22nd, 1999) PokemonGSC Route25.png

The DMYMAP version combines Routes 24 and 25 into a single map. The ledge in the upper left corner of the map is covered in dirt, as it was in Gen I, instead of grass like the final. The early version's file name is ROAD2425.MAP, and the final is ROAD25.MAP.

Route 28

DMYMAP (October 6th, 1998) Final (June 3rd, 1999)
PokemonGSC ROAD128.FLD early.png PokemonGSC Route28.png

Not only is the celebrity's house missing, but the entire tileset is different. In the DMYMAP version, since it directly connects to Route 27 to the south, it uses the Johto tileset. In the final, it uses the Kanto tileset. The early version's file name is ROAD128.FLD, and the final is ROAD128.MAP.

It's Mt. Silver again! Early file name is FUJI.FLD, the one leftover in the final game is FUJI.MAP, and the final map is SIROGANE.MAP.

Sprout Tower Floor 4

All nine floors of a prototype Sprout Tower are included in the final game, with the exception of the fourth. The floor was fully mapped, but its inclusion was commented out for unknown reasons; it was only recovered during the Gen II source code leak, in the file SOURCE\MAPDATA\TOWER_F4.MAP.
