Unused Maps

This is a sub-page of Pokémon FireRed and LeafGreen.

Ruby & Sapphire Leftovers#

Many interior map layouts from Ruby and Sapphire were carried over to FireRed and LeafGreen, though they now look messed-up due to the tileset and tilemap data being modified.

The Record Corner was also carried over, alongside its map script. However, the actual Record Corner behavior was dummied out. Map ID 49.

Map Duplicates#

Both the Celadon Restaurant and the Celadon Hotel have unused map duplicates. The used versions sit at IDs 190 and 191 respectively, while the unused ones are IDs 267 and 268.

Script Data#

Trainer Tower Rooms#

Every "battle floor" of the Trainer Tower contains an unused, hidden instance of the owner. The one on the first floor has no script assigned, but each subsequent floor has the usual roof one defined. From the second floor onward, an inaccessible warp is also present, with it leading to the tower elevator.

Pewter City Guide#

Pewter's city guide has an inaccessible event tile, which has odd scripting associated with it. Accessing it triggers the NPC's usual intro text, then the "Go take on Brock!" closing dialogue, and only then does he start moving... except the player doesn't follow. The player regains control the second the boy goes off-screen, and moving in any direction refreshes him back to his starting position.

Route 23 Guards#

Route 23 has a large amount of unused duplicate event tiles related to the various badge check guards.

Unused Warp Data#

Standard Buildings#

For some reason, the game contains a large amount of unused duplicate warps, placed right next to the used ones. This only applies to the ground floor of Kanto buildings, with the exceptions being the two new houses in Cerulean, Fuchsia's move deleter, the Pokémon Lab (lobby aside), and the Indigo Plateau as a whole.

As mentioned earlier, 2F through 8F of the Trainer Tower also have an extra warp to the elevator.

Overworld#

• Cerulean City - The back entrance to the burglarized house has an extra warp.
• Celadon City - The Condo's back entrance has two extra warps.
• Fuchsia City - The back entrance to the fishing guru's house has an extra warp.
• Route 12 - The back entrance to the gate house has an extra warp.
• Route 22 - The entrance to the reception gate has an extra warp.
• Route 23 - The entrance to the reception gate has an extra warp.

Dungeons#

• S.S. Anne 1F - The entrance door and the kitchen door have an extra warp each.
• S.S. Anne 3F - The exit to the deck has an extra warp.
• Victory Road 2F - The exit to Route 23 has two extra warps.
• Rocket Hideout B1F - Elevator door has two extra warps.
• Rocket Hideout B2F / B4F - Elevator door has one extra warp.
• Rocket Hideout elevator - Has an extra warp.
• Silph Co. 1F - Entrance has two extra warps.
• Pokémon Mansion 1F - Entrance has two extra warps, the stairs to 2F and the shortcut have one.
• Safari Zone - Each path has an extra warp, same for the main gate's back entrance.
• Pokémon Tower 1F - Entrance has two extra warps.
• Power Plant - Entrance has two extra warps, the shortcut has one.

Unused Houses#

Kanto#

Routes 6, 19, and 23 all have an unused interior map consisting of a generic NPC house. All three are defined properly internally, but lack any data related to warps, events, or object placement. They are programmed to play the same track as the routes they're associated with, but that's about it. Found at map entries 18.1, 27.0, and 29.0 respectively.

The only noteworthy thing about these maps is the Route 19 one, which could suggest that the devs originally wanted to port over the Summer Beach House from Yellow.

Seven Island#

Map 31.1 is the room hidden behind boxes in the old lady's house on Seven Island. This was intended to house trainers transferred using e-Reader cards, similar to the Battle-e cards in Ruby and Sapphire, but no such cards were ever distributed even in Japan, so the functionality goes unused in every region.

Map 31.5 is an unused house for Seven Island that lacks event data, and uses the same layout as the Route 12 Fishing Guru's house, and the Water Path Beauty's house. It's possible that Seven Island once had an NPC who would check how big a certain Pokémon is, due to the poster on the wall.

Unused Sevii Routes#

Likely to avoid confusion with the Johto routes, the Sevii Islands routes were given proper names, instead of numbers. However, internally each one has a given number, using the naming scheme "n_road###_map", with the "n" likely coming from "nanashima", the Japanese name for the Sevii Islands. As one can see, a total of seven routes were removed prior to release, with all of them remaining in one form or another in the final games' data. Namely, map layouts.

Sevii Isle 6 to 9#

ID #	Map Header	Map Section	Map
242	SEVII ISLE 6
243	SEVII ISLE 7
244	SEVII ISLE 8
245	SEVII ISLE 9

This first set of maps consists of four routes which, while they can be loaded in-game, lack object/event placement or wild encounters. Sevii Isle 6 and 7 were "blanked", in that their size was set to 1×1, though their collision data still remains, with the former consisting of one surfable tile, and the latter of the impassible upper-left corner of a sea border rock. Judging from the Town Map data, they would have been short routes, being the only routes aside from the Sevault Canyon entrance to have a town map "section" of 1.

The two surviving maps from this set showcase basic sea routes, whose straight rock borders are evident of how unfinished they are. They also reuse the generic Kanto secondary tileset, as opposed to the unique Sevii Islands one. The cave entrance used on Sevii Isle 8 was also overwritten by a piece of rock formation at some point.

Early (Mockup)	Final

As seen from their layout and Town Map placement, these routes would have been situated around an earlier iteration of Four Island, which in the final games is the only island to not have any routes. It also turns out that Four Island started out much smaller, the same size as One Island, Five Island, and Seven Island. It's then likely that the cave present in Sevii Isle 8 was Icefall Cave, or at the very least a precursor to it.

Sevii Isle 22 to 24#

ID #	Map Header	Map Section	Map
258	SEVII ISLE 22
259	SEVII ISLE 23
260	SEVII ISLE 24

This second set of maps consists of three routes. While their actual map files still remain intact, they lack an entry in the global map table, and lack both collision and event data entirely. They also reuse the generic Kanto secondary tileset, as opposed to the unique Sevii Islands one. The sand corner tiles are also placed incorrectly, which is not the case in the previous Sevii Isle map set, suggesting these tiles were moved around early in development.

Early (Mockup)	Final

As seen from their layout and Town Map placement, these routes would have been situated around the Tanoby Ruins. The sand bank from Sevii Isle 22 also likely extended slightly into the eastern-most side of the Tanoby Ruins route. Just like the Sevii Isle 6 to 8, those routes were likely scrapped after being deemed redundant.

Early Navel Rock#

Defined right after the unused Sevii Isle 24 route is an equally unused desert island map, at listed id 261. The leaked source code reveals this area to be an early Navel Rock, identified as n_heso01_map, as opposed to the final n_road_heso_map, with "heso" ( へそ) meaning "navel".

While the general layout is similar, this is clearly a rough outline more than anything, lacking any cave entrance or harbor building, and reusing the generic Kanto secondary tileset. Moreover, much like Sevii Isle 22 through 24 this map doesn't have an entry in the global map table, and lacks event data entirely.

Unseen Areas#

Vermilion City Harbor#

The infamous truck near the S.S. Anne was carried over, though here it's actually possible to access it under normal means.

In the Gen I games, this required either trading in a Pokémon that knows Cut, or getting HM01 from the Captain and then blacking out while still on the boat, which would warp the player to a Pokémon Center and prevent the S.S. Anne from leaving port. The latter setup has been patched in this remake, though the trade option was taken into account, with the rival no longer showing up on the boat after being defeated in the Pokémon Tower.

By skipping the S.S. Anne and coming back later with a Pokémon that knows Surf, the player is rewarded for thinking outside the box when checking out the truck, receiving a hidden Lava Cookie, an item which is normally only obtainable much later on.

Diglett's Cave#

Being a diagonal path, most of Diglett's Cave goes unseen. This includes a lot of intricate detailing in the rock formations.

Mt. Ember#

The second floor of Mt. Ember has some pretty nice effort put into its rock walls. Sadly, virtually all of this effort goes unseen.

Trainer Tower#

The area around Trainer Tower on Seven Island has a lot more ocean than what's visible in-game. Why it's there is anyone's guess.
