Prerelease:Pokémon Red and Blue/Unused Maps

This is a sub-page of Prerelease:Pokémon Red and Blue.

A large amount of maps were archived in the source code, albeit with a lot of them being subject to what was either corruption or incorrect parameters. Despite this, these maps give us an incredibly informative glimpse regarding how the region of Kanto evolved over time.

"Version 1"

Overview

The earliest known iteration of Kanto, which appears to date back to around 1992. While the overworld layout had already been established, many of the routes at this point are just blank roads, while several cities barely have anything in them. The overworld tiles are also much simpler and cruder than in later iterations, with perspective namely being amiss and the artstyle being radically different.

Though in surprisingly good shape, this version of Kanto does however contain instances where a map uses the wrong blocks. The first one is a wall portion with a "CVS" sign on it, and, as seen by its placement, it appears to have once been a duplicate four-block block that was ultimately overwritten. The other incorrect block is a garbled mess of sign corners, which as seen in the "Kanto V1" block file was used as padding near the end of the list. As such, it's clear that there are actually different instances of this block where a certain one should be used. As such, the reconstructions that will be provided will use educated guesses when it comes to what goes where.

Incorrect Block	Proper Block

Exteriors

Pallet Town

Early Map	Final Map

Only contains two small buildings, meaning that Professor Oak's lab is absent, with him either living with his family or having his lab in another city. The map is also surrounded by water on all sides, instead of just having a beach to the south. Trees also encircle the town, as opposed to the final games' pillars. Tall grass is also found inside the town, as well as a few other cities throughout Kanto, though whether this was standard tall grass or purely decorative weeds is unknown.

Route 1

Early Map	Final Map

Is more densely wooded, features less tall grass, and has a more natural curvy path. Also worth noting is that across this iteration of Kanto are a series of numbered signs, with them likely intended to display the current route's number. However, they all state "15", likely because the other number tiles had not been implemented yet.

Viridian City

Early Map	Final Map

The overall layout is the same, though the body of water is missing, and the way to Route 22 is blocked off by fences. As for the wooded area, it is found in the upper-right corner of town as opposed to the upper-left one, and its shape seems to indicate it had originally been designed to hold items.

Interestingly, the roads exiting town are paved, while Route 1 and 2 are completely grassy. This is perhaps a leftover from an even earlier iteration of Kanto, where Route 1 and 2 were still placeholder paved roads.

Route 2

Early Map	Final Map

The lower half of this route is the most different, featuring more tall grass as well as a river and bridge which are nowhere to be seen in the final games. A clearing sits where Viridian Forest normally lies, and the entrance to Diglett's Cave is quite larger. No houses nor gates are present in this iteration.

Pewter City

Early Map	Final Map

While the layout is somewhat similar, this area is nonetheless very different. Namely, where the Gym normally lies is a large C-shaped building, and the two bodies of water swapped with an enclosed flower patch. The paved road oddity from Viridian City also makes a return here. Interestingly, there are mountains to the north of the city, as there would later be in HeartGold and SoulSilver.

Route 3

Early Map
Final Map

The first of the placeholder routes. Indeed, virtually all routes in this iteration of Kanto are wide empty roads, the latter ones styled as highways, with the corresponding route number written out of tall grass, though Route 3 notably lacks the latter aspect.

Route 4

Early Map
Final Map

A stand-in for Route 4, whose later half lacks pavement altogether.

Cerulean City

Early Map (Original)
Early Map (Corrected)
Final Map

Has a completely different layout, and only shares the fact that it is a city surrounded by water. Namely lacks the entrance to the Unknown Dungeon, and has a rather odd looking pretzel-shaped Inn.

Route 24

Early Map	Final Map

A stand-in for Route 24.

Route 25

Early Map
Final Map

A stand-in for Route 25, with it appropriately ending in a dead-end.

Route 9

Early Map
Final Map

A stand-in for Route 9.

Route 5

Early Map	Final Map

A stand-in for Route 5.

Saffron City

Early Map	Final Map

Completely vacant, with it so far being a simple partially blocked-off crossroad.

Route 6

Early Map	Final Map

A stand-in for Route 6.

Vermilion City

Early Map (Original)
Early Map (Corrected)
Final Map

Has a completely different layout, lacking the iconic harbor and featuring quite a lot of tall grass. Appears to have been conceptually switched with Celadon City, as here the town is seen sporting what is likely a department store, as well as Game Freak's building (as seen by the GF sign near the entrance of town).

This map is also essentially proof that the garbled block is actually at least two different kinds of walls. One of them was likely making use of the Poké Ball sign, though the other one may have just been a blank wall for all we know.

Route 11

Early Map
Final Map

A stand-in for Route 11.

Route 10

Early Map	Final Map

A stand-in for Route 10.

Lavender Town

Early Map (Original)
Early Map (Corrected)
Final Map

Has a completely different layout, lacking the iconic Pokémon Tower and a lot of the houses. Looks more like a typical drive-by town, with very few houses, a minuscule convenience store, and an overgrown hotel. Appears to have once being close to the water to the east, while in the final games this spot is mountainous.

Route 12

Early Map	Final Map

A stand-in for Route 12.

Route 8

Early Map
Final Map

A stand-in for Route 8.

Route 7

Early Map	Final Map

A stand-in for Route 7.

Celadon City

Early Map (Original)
Early Map (Corrected)
Final Map

Has a completely different layout, lacking the iconic department store and a lot of the houses. Appears to have been conceptually switched with Vermilion City, as here the town is seen sporting what is likely a harbor, that and it is also surrounded by water, while the final city is completely landlocked.

Another case of odd unknown tiles, as there are way too many affected buildings for them all to have had a purpose/sign.

Route 13

Early Map
Final Map

A stand-in for Route 13.

Route 14

Early Map	Final Map

A stand-in for Route 14.

Route 15

Early Map
Final Map

A stand-in for Route 15.

Route 16

Early Map
Final Map

A stand-in for Route 16.

Route 17

Early Map	Final Map

A stand-in for Route 17.

Route 18

Early Map
Final Map

A stand-in for Route 18.

Fuchsia City

Early Map (Original)
Early Map (Corrected)
Final Map

Completely vacant aside from two buildings. While it lacks any hint of a Safari Zone, the northern half of town is oddly opened-up, which would made sense as a previous Kanto layout had a route north of town.

Route 19

Early Map	Final Map

An early version of Route 19. Is entirely made out of land, whereas the final version is a sea route which only features a very small northern shore. Also features two buildings, and while the final games has none there, Yellow would later add the Summer Beach House on this route.

Route 20

Early Map
Final Map

An early version of Route 20. Only features a tiny isle in lieu of the Seafoam Island. Interestingly lacks bollards restricting the player's path.

Cinnabar Island

Early Map	Final Map

A stand-in for Cinnabar Island, using the number 9, its corresponding number as seen in the Capsule Monster design documents.

Route 21

Early Map	Final Map

An early version of Route 21, with it featuring a lot of small isles instead of a few piers, as well as once again lacking bollards restricting the player's path. Interestingly, starting with FireRed and LeafGreen, this route would ultimately end up containing a series of small islands.

Route 22

Early Map
Final Map

A stand-in for Route 22, with it getting more and more overgrown the closer you get to Route 23.

Route 23

Early Map	Final Map

A completely different earlier iteration of Route 23, with it appearing as a winding mountain path with lacks any sort of water, man-made structures, or even the Victory Road.

Indigo Plateau

Early Map	Final Map

Another wildly different design, with an imposing cave standing where the League sits in the final games. The League had definitely not been conceived yet, and if anything the dungeon that would have been found here is closer to what the Victory Road would end up being. A small hole can also be seen in the upper-right corner, perhaps originally intended for the player to access an otherwise inaccessible portion of the cave system below.

Scrapped Town

A town that was scrapped early in development, and likely corresponds to the area referred to as "C" in the design documents. What was seemingly alluded to as a city the size of Saffron City turns out to be a town the size of Pallet Town, with the purpose of this area still as unclear as it was before. Worth noting is that this map is the only place in "V1 Kanto" where a truck is found, the exact same graphic still present in the final games, found off-screen in the Vermillion City harbor.

Interiors

Poké Mart (Standard)

Early Map	Final Map

An early Poké Mart which features way less shelves, as well as a counter that is in front of the entrance, as opposed to beside it.

Poké Mart (Large)

Early Map	Final Map

A larger version of the Poké Mart seemingly intended for the two-story building in Vermillion City. Was reworked into the upper floors of the Celadon City department store in the final games.

Champ Cup

Perhaps what Gyms originally looked like, which could be supported by internal names for the overworld sprites revealing that Lance's spot was originally occupied by an NPC type known as "Judge", whose role would have likely been that of the anime's battle judges.

"Version 2"

Overview

In comparison to the "Version 1" overworld, this one suffers from a rather different blockset when compared to the final one, rendering some areas almost completely undecipherable. This isn't helped by the fact that some blocks appear to have been genuinely mistakenly placed when the maps were being made, or that some building were clearly still placeholders. Moreover, a lot of maps are either totally or partially missing, perhaps due to memory corruption or incorrect parameters (red pillars will be used to denote missing map portions). Despite all this, a number of interesting differences can still be noted. Appears to date back to around 1994.

Worth noting is that unlike with V1, the tileset for this iteration of Kanto was not provided along with the rest of the asset files. As such, the final Red and Green tileset will be used instead. As for the blockset, a reconstruction of the early one used by these maps will be provided below.

Early Blockset	Final Blockset

Exteriors

Pallet Town

Early Map (Original)	Early Map (Corrected)	Final Map

Is still surrounded by trees, and lacks the pillars blocking the path to Route 21. Otherwise pretty much identical to final.

Route 1

Early Map (Original)	Early Map (Corrected)	Final Map

Has one less wild grass patch when compared to V1, that and it has an even more natural look as well. Still wildly different from the final layout.

Route 2

Early Map (Original)	Early Map (Corrected)	Final Map

Now features cuttable trees, though cutting them only reveals separate areas instead of the straight shortcut seen in the final games. Viridian Forest is also completely missing, and the entrance to Diglett's Cave is a house, despite being a cave in V1. Interestingly, as seen here and all throughout this version of Kanto, gate houses appear to have not been implemented yet. As such, the extra houses were likely used as warp points. Still wildly different from the final layout.

Route 3

Early Map
Corrected Early Map
Final Map

The first of the partially missing maps. Also has what appears to be unintentionally shuffled tiles on the rightmost side. The visible layout, however, does appear almost identical to final, though with a paved road and more tall grass.

Route 4

Early Map
Corrected Early Map
Final Map

Has a less hilly landscape, and the entrance and exit to Mt. Moon are farther apart. Speaking of Mt. Moon, it was originally an optional dungeon, before being made required in the final games.

Cerulean City

Early Map
Corrected Early Map
Final Map

While almost entirely missing, the remaining portion of the map shows a similar layout, though namely lacking the exit to the Route 25 shortcut, which as seen on Route 24 and 25 had not been conceived yet.

Route 24

Early Map (Original)	Early Map (Corrected)	Final Map

Is entirely surrounded by water, and as mentioned above the shortcut is missing entirely.

Route 25

Early Map
Corrected Early Map
Final Map

Has a much simpler layout, lacks the tree maze and pond, and is once again entirely surrounded by water. Bill's Cottage is present, though as a single story house instead of a two story one, and lacking its "garden".

Route 9

Early Map
Corrected Early Map
Final Map

Has a much simpler layout, being a rather straight paved road instead of a winding mountainous path. Also features more water, and appears to lack any obstacle near its entrance, perhaps meaning you were able to go all the way to the Rock Tunnel. This was likely changed so that player would not get lost trying to navigate the cave in the dark. This route also features a little area blocked by cuttable trees, likely once the place where an item resided.

Route 5

Early Map (Original)	Early Map (Corrected)	Final Map

Another partially missing map, this one even coming with an interesting alternate placeholder design for the gate building.

Saffron City

Early Map
Corrected Early Map
Final Map

Quite a different layout. Namely, what is clearly Silph Co. is represented as a large pile of the bollard-like pillar, which as seen in other places was used to represent incomplete structures. The "building" is way larger than the final one, and is surrounded by a moat, which in the ends causes quite the imbalance with the rest of the area. The final version of the town ended up going with a less grandiose Silph Co., but filled up the newly empty space with more buildings, giving the area the feeling of large populated city.

Route 6

Early Map (Original)	Early Map (Corrected)	Final Map

A simple straight paved road. Features a rather odd alternate route which also leads to Vermillion City, but there is blocked by a cuttable tree.

Vermilion City

Early Map
Corrected Early Map
Final Map

Still a bit barebones, and featuring less water overall. Interestingly, the gym isn't blocked by anything, and the unfinished area at the bottom seems to have been the harbor, which in the final games is found on a separate map. Funnily enough, the "Machop plot" is already present.

Route 11

Early Map
Corrected Early Map
Final Map

Lacks the winding grass path, and features two likely accidentally placed plank tiles. The exit to Diglet's Cave's is once again shown as a house.

Route 10

Early Map (Original)	Early Map (Corrected)	Final Map

Surprisingly close to final, with only a cave entrance sitting where the Power Plant should be. The Pokémon Tower also extends much further up into this map.

Lavender Town

Early Map (Original)	Early Map (Corrected)	Final Map

Now much closer to the final version, though with way more signs, a trait shared with a few other areas. It's then possible that these signs were like in-game sticky notes, which would have contained basic story details or things to remember. The Pokémon Tower is here made out of Gym building, and is slimmer than what is seen on Route 10, perhaps meaning that the latter was made later down the line.

Route 12

Early Map (Original)	Early Map (Corrected)	Final Map

Lacks the mountainous part at the top, and is a simple paved road instead of the series of piers, though it is interesting for featuring four rock formations at the crossroad. While the gaps between them is too wide for Snorlax to fill them it's possible that it wasn't originally intended to serve as a progression blocker. The bottom of the road, meanwhile, has some rather interesting looking cliff walls which are nowhere to be seen in the final games, giving the area a more scenic look.

Route 8

Early Map (Original)
Early Map (Corrected)
Final Map

Has a somewhat similar layout, but lacks the ledges and enclosed patch of tall grass. Also features little ponds not seen anywhere on the final map.

Route 7

Early Map (Original)	Early Map (Corrected)	Final Map

Pretty much identical to final, though lacking the tall grass and featuring an extra house.

Celadon City

Early Map (Original)
Early Map (Corrected)
Final Map

Has a somewhat similar layout, though lacking a lot of houses.

Route 13

Early Map (Original)
Early Map (Corrected)
Final Map

Lacks the pole maze, the patch of grass, and features a cliffside.

Route 14

Early Map (Original)	Early Map (Corrected)	Final Map

Another map that was almost entirely wiped by corruption. Once again lacks the maze and still features cliffs as seen on route 12.

Route 15

Early Map (Original)
Early Map (Corrected)
Final Map

Is surrounded by water, and features a simpler layout.

Route 16

Early Map (Original)
Early Map (Corrected)
Final Map

Basically identical to final, though namely having a much, much wider eastern route, supporting the idea that Snorlax wasn't originally intended to block parts of the overworld.

Route 17

Early Map (Original)	Early Map (Corrected)	Final Map

Interestingly features an opening on the right side which lines up pretty close with the scrapped alternate road "9-3" from the concept pitch. This may reveal that this route was originally mistakenly built using outdated reference material, before being hastily corrected.

Fuchsia City

Early Map (Original)
Early Map (Corrected)
Final Map

Is surrounded by water and lacks a lot of houses, though what is likely the Warden's house is already there. The exhibits are nowhere to be seen, and the Safari Zone building appears to have once been entered from the left as opposed to from the front.

Route 19

Early Map (Original)	Early Map (Corrected)	Final Map

V2 is not that different from V1 from what can be seen, though a pier and a cliff wall can be noted as additions.

Route 20

Early Map (Original)
Early Map (Corrected)
Final Map

The "rock" formations are way more natural, Cinnabar Island features an actual beach with a pier, and in lieu of the Seafoam Islands stands what appears to be a lighthouse. The latter aspect could be supported by the Pokémon Tower tileset featuring what resembles a light fixture, and by Gold and Silver later reworking the idea of a lighthouse dungeon.

Cinnabar Island

Early Map (Original)	Early Map (Corrected)	Final Map

The general layout is there, but features more houses, more signs, and more land overall. The entrance to what is likely the Pokémon Mansion is also blocked by cuttable trees, which would be fitting seeing how it is an abandoned building.

Route 21

Early Map (Original)	Early Map (Corrected)	Final Map

Features a beach, as well as a house on a small island, both elements that are nowhere to be seen on the final map. The tall grass patch near Pallet Town is also missing.

Route 22

Early Map (Original)
Early Map (Corrected)
Final Map

The overall layout is there, but is once again less hilly.

Route 23

Early Map (Original)	Early Map (Corrected)	Final Map

Is a rather boring straight road, only featuring a central pond with two islands on it. Interestingly enough, the idea of decorative walls is already present, albeit in a rather crude form.

Indigo Plateau

Early Map (Original)	Early Map (Corrected)	Final Map

Resembles its Gold and Silver counterpart than its original Red and Green one. Features an additional house on the side that is not present in the final games, perhaps an unmarked Pokémon Center or Mart.

Interiors

Prof. Oak's Lab

Early Map	Final Map

Identical to final aside from the tileset difference. Interestingly, both this map and its corresponding tileset are labeled "Oak School", which while odd would make sense as in Japanese Oak is known as a teacher instead of a professor.

Burglarized Home

Early Map	Final Map

The burglarized house in Cerulean City is identical to final, aside from lacking one of its potted plants, its entrance mat, windows, and having differently arranged debris. This map also has some empty space around it, and it can be seen making use of an earlier iteration of the tileset.

Underground Path 5-6

Early Map	Final Map

Identical to final, aside from featuring a staircase in the middle, which may have led to the extra house on Route 7. The block line which featured the stairs was removed entirely in the final games, causing a graphical issue at the bottom of the map in the final games due to not enough map being there to fill the newly available space.

Underground Path 5-7

A scrapped secondary underground path which would have connected Route 5 to Route 7, its entrance visible in the V2 iterations of each roads. The final games ultimately replaced this area with a secondary underground path connecting Routes 7 and 8.

Fighting Dojo

Early Map	Early NPC Data	Final Map	Final NPC Data

Is shorter, features a Buddha statue, stained floor planks. Also has some incorrect tiling. The Poké Balls are missing entirely, and the NPC arrangement is also wildly different here, featuring only one trainer, likely the Karate Master. The sprite used for this NPC also essentially proves that what is Koga's exclusive spriteset in the final games was originally used for the Blackbelt trainer class.

Rocket Hideout

Map
Room 1	Room 2	Room 3

Three rooms which would have been part of the Team Rocket Hideout of Celadon City. Appears pretty barebones and incredibly small, perhaps meaning that the Hideout was originally a series of small rooms rather than an open series of floors.

Pokémon Tower

	Early Map (Original)	Early Map (Corrected)	Final Map
1F
2F
3F
4F
5F
6F
7F

V2 Blockset	Possible Blockset

The Pokémon Tower here features much larger maps, as well as quite a few incorrect blocks, and as such the reconstructions that will be provided will use educated guesses when it comes to what goes where. Floors 3 and 4, interestingly enough, are of floor 2, which causes some inconsistencies when it comes to the ascending and descending stairs.

As seen on the other early Pokémon Tower maps, an elevator was once present in the building, but was ultimately scrapped and replaced with Mr. Fuji warping you down to the base floor once you rescue him.

Seafoam Islands

A scrapped floor for the Seafoam Islands, this one labeled as "B5F", making it the likely original spot where Articuno was found.

Cerulean Cave

	Early Map	Final Map
2F	/
1F
B1F
B2F		/

Cerulean Cave, also known as the "Unknown Dungeon", once sported a radically different design which made use of what later became the Safari Zone tileset. Moreover, not only is each floor completely different, but the ordering is too, with the floors going from 1F to B2F as opposed to 2F to B1F.

Victory Road

Early Map	Final Map

An earlier version of the third floor of the Victory Road. Much of the ruble was removed, a switch was moved across the room, the two holes were removed, an ascending ladder was added and so was a pressure switch.

Moltres Room

A scrapped map only referred to as "Moltres Dungeon". Likely a placeholder map hastily thrown together when Moltres was moved from Cerulean Cave to Victory Road. In the final games, Moltres lacks its own room.

Pokémon Gyms

Map
Gym 1	Gym 2	Gym 3	Gym 4
Gym 5	Gym 6	Gym 7	Gym 8

Incredibly early iterations for the different gyms. The Viridian and Pewter gyms have identical maps, which appear to have served as the original placeholder design. Interestingly, Fuchsia and Cinnabar appear to have been swapped around (with the doors going to Blaine, and Koga instead getting the invisible walls).

NPC arrangement is known to exist, with the layout consisting of a Game Boy kid, four trainers, the Gym Coach, a little boy and his Pokémon where the leader should be, as well as two instances of Lance. The latter are interesting, as early internal names for the overworld sprites reveal that this sprite would have also been used by "Judges", which would have likely opened the door to let you confront the leader once all the other trainers had been defeated. They were likely scrapped due to them being redundant.

To finish with the Gyms, an interesting map was also included in the leak, this one known simply as "Boss Gym". This was definitely intended for Giovanni, meaning that while the latter was likely not a gym leader, he still add his own unofficial gym/lair.

Silph 2

Map
Floor 1	Floor 2	Floor 3	Floor 4

It appears that Silph Co. was so great Game Freak just couldn't resist making a second one! This secondary area would have been accessed through the main hall, and consisted of a gauntlet where the player would have to defeat trainers as they ascend. Trainer Data is known to exist for the first four floors: Floor 1: Youngster, Bug Catcher, Lass, Brock, Jr. Trainer ♂, Jr. Trainer ♀, Super Nerd, Misty. Floor 2: Hiker, Fisherman, Sailor, Lt. Surge, Gentleman, Channeler, Gambler, and Erika. Floor 3: Engineer, Pokémaniac, Rocket, Koga, Scientist, Jack, Biker, and Chief. Floor 4: Cue Ball, Bird Keeper, Burglar, Sabrina, Swimmer, Beauty, Rocker, and Blaine.

While no data for a fifth floor is known to exist, it would have likely consisted of the remaining trainer classes, as such the Blackbelt, Juggler, Psychic, Giovanni, Tamer, Cooltrainer ♂, Cooltrainer ♀, and either the Rival or Professor Oak. The sixth floor, meanwhile, has wild encounter data which includes none other than Mewtwo, meaning that this is where it would have originally been found before it was ultimately moved to Cerulean Cave.

Silph League

	Map
Basement Floor 1
Basement Floor 2
Basement Floor 3
Basement Floor 5
Basement Floor 6
Basement Floor 7
Basement Floor 8
Basement Floor 9

The Pokémon League is shown as having a dungeon consisting of several basement floors which, as denoted by their designs and wild encounter data, are based after dungeons found earlier in the game. Moreover, the map section of the original leak reveals that the League was originally found in the Silph Co. Building, so perhaps this was "Silph 1" (or "Silph Area 1"), as in the main area which was the original place of the Indigo League.

The first floor has the rates of Viridian Forest, but is visually closer to the Safari Zone. The second floor is based after Mt. Moon, with matching rates. The third floor is clearly based after the S.S. Anne, with four cabins, meaning that to progress the player would to find the right door or likely risk fighting a trainer. The fourth floor is missing, but was likely based after the Rock Tunnel, as seen by its rates. The fifth floor is based on the Pokémon Tower, the sixth on the Rocket Hideout, the seventh on the Safari Zone, and the eight on the Pokémon Mansion. The ninth and final map is identical to Lance's room in the final games, the area even coming with NPC data revealing that the player would have battle the Elite Four members back to back before facing the Champion (who in the final was moved to a separate map).

Garden

A scrapped map only referred to as "Garden". Likely a test map of sorts to see how decorative maps could be built.

Cage

Map	NPC Data

A map which would have been found in Fuchsia City, likely meaning that the Pokémon displays were to be inside of buildings instead of out in the open. We known that a standard male NPC would have been found there, likely remarking the Pokémon found behind the glass.

Gambler

A cut map interior which is only known as "Gambler", thus perhaps linking it to Celadon City, and its unused house warp.

Interior Room

A scrapped interior type which simply consists of a table with a row of bookshelves. Nothing more, nothing less.

Broken Room

Map (Original)	Map (Corrected)

A rather odd elongated map which makes uses of the overworld tileset. May actually have suffered from incorrect parameters, as removing the last few blocks (which are 00) reveals that this map perfectly fits the standard 4x4 room dimension. This map may actually be the original Inn/Pokémon Center interior, as using the corrected V2 Inn blockset actually matches pretty well with the layout seen here. However, it appears that some of the blocks were shifted around, and as such reconstructions of the original layout (using the pointers from the final blockset for clarity's sake) will be provided below:

	Layout	V2 Blockset (V2 Tileset)	V2 Blockset (Final Tileset)
Original Arrangement	03 00 01 02 07 04 05 06 08 08 08 08 08 09 0A 08
Possible Arrangement	0E 10 01 02 07 04 05 06 03 03 03 03 03 0A 0B 03

Miscellaneous

A handful of maps from after V2, but before the final releases:

Indigo Plateau

Early Map (Original)	Early Map (Corrected)	Final Map

A later iteration of the early Indigo Plateau map, still using the tower design and lacking its exclusive tileset. While the cellset is clearly closer to final, it still features the block issue on the top of the ponds.

Gatehouse

Early	Final

A surprisingly interesting map, as it is listed as being linked to Cinnabar Island. It's then possible that at one point the houses there were to use the design of the gatehouses, in a similar way that some houses have their interior based after the S.S. Anne cabins. The NPC arrangement matches that of the first Viridian Gatehouse, though with an extra fisher NPC (likely a mistake when this map was repurposed for the Viridian Gate, as this NPC visually matches the in-battle sprite for the Bug Catchers).

Burglarized House

Early	Final

The burglarized house in Cerulean City is identical to final, though lacking the two owners and with the Rocket Grunt being inside of the home instead of hiding in the back garden.

Fuchsia City Office

Early	Final

The Safari Zone Office from Fuchsia City. Identical to final aside from the Warden ultimately being moved to a different map and being replaced with another park employee.

Saffron Pokémon Center

Early	Final

The Saffron City Pokémon Center, which in the final games shifted the Gentleman to the left and added a salesgirl to block the access to the Cable Club.

Saffron Poké Mart

Early	Final

The Saffron City Poké Mart, which in the final games swapped the young man and the old man. Funnily enough, the latter also ended up becoming a Lass in the final games.

Saffron City

Early	Final

All the NPCs are there, but not necessarily in their final spot. Interestingly, the scientist and grunt are clearly placed on a building, suggesting that this NPC layout is from a slightly earlier iteration of the map.

S.S. Anne Cabins

	Early	Final
First Set
Second Set
Third Set

While being grouped together by groups of six on two maps in the final games, it appears that originally each of the S.S. Anne cabins had individual maps (though for simplicity's sake here they will be presented in a similar fashion to the final one). The main entrance of the ship only featuring three cabins instead of six, with repositioned NPCs, and with the little girl having a monstrous Pokémon as opposed to a cute one. The ship's upper floor is also mainly identical, with the NPCs once again repositionned and with an old man added. The ship's lower floor, meanwhile, is completely different, and while the last cabin wasn't present in the leaks it's very likely because even back then it wasn't being used.

Victory Road

First Iteration
Second Iteration
Third Iteration
Final Iteration

No less than three different early iterations of the object layout of the second floor of Victory Road. The first version here has a rather different layout, namely lacking Moltres, with the second one only changing which way the male trainer and Blackbelt face. The third version is basically identical to final, aside from the Blackbelt and Juggler being in slightly different spots.
