Pokémon FireRed and LeafGreen are remakes of the first two Pokémon games, Red and Green. Aside from the graphics and interface being upgraded to that of Ruby and Sapphire, the games received many new elements, most notably the Sevii Islands.

At least Japanese FireRed v1.0 has the Sound Check like Ruby and Sapphire, except it was removed in localizations this time around.
To access it, patch 0x12f342 to 00 00 00 00 and 0x12f35c to 01 FF 09 08 in a Japanese FireRed v1.0 ROM to replace the New Game entry on the main menu with a call to Sound Check (this has the effect of running Sound Check after the title screen if there is no save file).
The misspelling of the word "stereo" in the Driver Test from Ruby and Sapphire was fixed in the equivalent of FireRed and LeafGreen as well as of Emerald, being now correctly spelled in katakana (ステレオ) instead of hiragana (すてれお), and the entry itself was also moved to the bottom.
- 18.1, 27.0, and 29.0 are three identical unused houses without event data on Routes 6, 19, and 23 respectively. The one on 19 is where the Pikachu's Beach minigame was in Yellow, so it is possible that they wanted to remake it as well.
- 31.1 is the room hidden behind boxes in the old lady's house on Seven Island. It only has a warp to the room above.
- 31.5 is an unused house map for Seven Island that lacks event data. It's possible that this could have housed an NPC who would check how big a certain Pokémon is due to the poster on the wall.
Sevii Islands 8, 9, 22-24
There is data in the game for Sevii Islands 8, 9, 22, 23, and 24, as well as what are probably early versions of 6 and 7. Interestingly, all of their names have a different syntax than the final islands (ex. Island Eight is called Sevii Island 8 rather than Eight Island.)
- The early 6 and 7 are blank and only one tile big. Expanding the map size reveals one tile each of their original map intact, with collision data to boot; 6 has a Surfable sea tile, and 7 has the impassible upper-left corner of a sea border rock. This implies that these were fully collisioned maps at some point, but they were "deleted" in the laziest way possible.
- 8 and 9 still have intact maps with collision data, though they are obviously incomplete.
- 22, 23, and 24 do not have maps, only headers. They were probably cut early on in development.
The maps for Sevii Island 8 and 9 can be explored ingame by either changing address 02031DBC to 0x03 and 02031DBD to 0x34 or 0x35 while going into any building or using the right code from the following table.
- The area around Trainer Tower on Seven Island has a lot more ocean than what's visible in-game. Its meaning is anyone's guess.
- The infamous truck near the S.S. Anne is present. While the original glitch of blacking out after getting HM01 from the Captain (most commonly by losing to the rival fight) to prevent the S.S. Anne from leaving has been patched in this remake, it is still possible to trade in a Pokémon that knows Cut to avoid entering the S.S. Anne at all and then come back later with Surf. If the player fights their rival in the Pokémon Tower prior to returning, they will no longer be present in the S.S. Anne. Checking out the truck awards a Lava Cookie, an item accessible much earlier than normal.
- Like the Trainer Tower, Diglett's Cave takes up much more space than is actually visible in-game.
Several other maps, some of which are corrupted leftovers from Ruby and Sapphire, also exist in the game's coding. Some of these seem to be early versions of other maps in FireRed and LeafGreen or just duplicates. A complete list can be seen on Bulbapedia here.
Ruby and Sapphire Leftovers
Since key items cannot be transferred with a Pokémon, they're unused and most have no effect in FireRed/LeafGreen. The Mach Bike and Acro Bike do work, but act like the normal Bicycle. HM08 (Dive) also works and can be taught to Pokémon, but unlike normal HMs the move can be deleted freely.
Every secret base decoration and its associated data remains unused within FireRed and LeafGreen; descriptions for these items also remain.
A lot: Archie and Team Aqua, Maxie and Team Magma, Beauties, Cyclists, Hex Maniacs, Gym Leaders, the Elite Four and Champion, etc. While you can battle them in-game through hacking, their Pokémon data is gone, so they don't have any Pokémon to battle with.
Additionally, the backsprites of Brendan and May in battle with their send-out animations remain in the game, only able to be seen in normal gameplay by partnering with a player using Ruby, Sapphire, or Emerald in a four-player link Multi Battle.
Most overworld weather goes unused, except for regular fog.
Since rain no longer occurs naturally, the related battle message is now unused.
It is raining.
Multiple scripts starting at 0x1638EC in the US 1.0 version remain as leftovers from the first Braille chamber, with the alphabet inscribed in groups of three (ABC, DEF, GHI ...). A room similar to it was likely planned but then scrapped in favor of having a Braille table included in the booklet.
Starting at 0x1BE38B in the US 1.0 Version is the script for checking and prompting the player to use Dive leftover from Pokémon Ruby and Sapphire, along with the behavior byte used for dive tiles.
Music and Sound Effects
Confirm that the PokéNav and Contest effects are in fact unused and not repurposed.
SE-TRACK-MOVE (sound effect 2B)
SE-TRACK-STOP (sound effect 2C)
SE-TRACK-HAIKI (sound effect 2D)
SE-TRACK-DOOR (sound effect 2E)
MUS-ME-KINOMI (music 106), used for Berry picking from trees.
|Name||Sprites||FireRed Offset||LeafGreen Offset|
|Brawly||369F28 - 36A227||369F08 - 36A207|
|Rich Boy/Contestant||372AA8 - 3733A7||372A88 - 373387|
|Camerman||38D5A8 - 38DEA7||38D588 - 38DE87|
|Running Triathlete (Female)||384828 - 385127||384808 - 385107|
The graphics for Brawly, the Cameraman and the Rich Boy/Contestant have no palette nor frame data assigned to them, but the Running Triathlete does. This has been copied directly from Ruby and Sapphire, however using this in FireRed and LeafGreen results in the sprite being coloured differently as the palette tag ID (1104) now describes a different palette:
|Ruby & Sapphire Palette||FireRed & LeafGreen Palette (Unused)|
While not technically unused, this text requires cheating to be seen. If the player interacts with the TV on the ground floor of their house from the sides or back, the same text string from Pokémon Red and Blue appears.
Oops, wrong side...
When the player attempts to use an item when they do not have any Pokémon, a normally unseen text string appears, returning from Pokémon Ruby and Sapphire.
There is no POKéMON.
Hacking a TM move to be Bug-type will cause the disc in the TM case to change color accordingly, possibly suggesting that Bug-type TMs were originally planned to appear in Generation III (though it's a bright shade of yellow, rather than green as it is in later games). Colors for nonexistent HM types also exist, though ???-type has no color and defaults to Normal-type.
Early Oak Sprite
There is an unused sprite of Oak with a design that differs from the final release. The sprite and palette data are uncompressed at locations 3CA6DC to 3CAEFB in FireRed and 3CA5AC to 3CADCB in LeafGreen. Additionally, there is an unused function that draws this sprite on the screen similarly to how the Professor Birch sprite is drawn in Ruby, Sapphire and Emerald during a new game's speech segment.
Unused Timer Ball Frame
The unused Timer Ball frame from Ruby and Sapphire remains unused for the same reason.
Unused Overworld Sprites
These Pokémon overworld sprites are never used in-game.

Keitaro posted this on the Jul forums. Investigate and document this further.
Male Player sprites
Unused Male Receptionist
There are overworld sprites for a male receptionist right after the used Cable Club and Union Room receptionists. These graphics are uncompressed in location 38B728 to 38BA27 in FireRed and 38B708 to 38BA07 in LeafGreen. This character has an object event ID of 67, as well as frames and a palette defined, however the game never uses the ID at all.
A chiptune-like version of the MUS-ME-ASA (music 0100), the "Pokémon Healed" theme, which sounds like the original from Red and Blue. It has the label MUS-KAIHUKU in Sound Check and its ID is 0119.
For the sake of consistency, every Pokémon in every game is given a Shiny variant, and Celebi is no exception. However, because the only way to obtain it legitimately was through distributions, the Shiny version of Celebi was left unobtainable through normal means. This sprite may still be seen (in a lighter hue) if a Shiny Pokémon Transforms into a Celebi.
Like "standard" Celebi and many other Pokémon, the sprite is identical to that of Ruby and Sapphire, where it was similarly unobtainable.
Mareep, Aipom, Pineco, Shuckle, Teddiursa, Houndour, Stantler, and Smeargle were meant to replace the Zubat found in Altering Cave after using Mystery Gift. The event distribution was probably scrapped because these Pokémon can be obtained from Pokémon Colosseum or Pokémon XD: Gale of Darkness, as well as in Emerald on the extended area of the Safari Zone (except Smeargle, which is found in Artisan Cave instead) - despite the fact Emerald also has an Altering Cave with the same design and (lack of) implementation.
Technically, this is implemented by its map script reading a numerical variable and selecting from one of 10 encounter tables (all of which specify only 1 Pokémon).
The game does contain a built-in implementation of an Altering Cave event, which attaches to the deliveryman in the top floor of the Pokémon Center and sequentially switches the selected Pokémon then displays:
Thank you for using the MYSTERY GIFT System. Recently, there have been rumors of rare POKéMON appearances. The rumors are about ALTERING CAVE on OUTCAST ISLAND. Why not visit there and check if the rumors are indeed true?
This however may not necessarily be indicative of how an official event would have worked.
Unused Held Items
Some Pokémon, when found in the wild, have a chance of holding an item. But some of the Pokémon that have assigned held item data can only obtained via evolution or other means, so their potential held items are never seen during normal gameplay. Notably, Kanto and Johto Pokémon in FireRed/LeafGreen use a different list for held items then what Ruby, Sapphire, and Emerald use, as well as all future games.

Isn't this in Ruby and Sapphire?
The movement table, located at 3A64C8, contains the directions the player or an NPC must move in. However, after the first five entries (steady, down, up, left, right), four more follow, resulting in diagonal movement when activated. Using them results in some glitches with warps and map rendering. It should be noted that the games feature buildings with otherwise strange diagonal corners, contrasting with the buildings of the original games.
This feature was not implemented in any final version until the X and Y releases.
Wild Double Battles
Some data suggests wild double battles were originally planned for this generation, but were delayed until Generation IV. For example, a string "Wild [buffer1] and [buffer2] appeared!" is located at 3FD2BF, and setting only bit 0 in the battle type flag at 02022B4C in the RAM results in such a battle, if used at the right moment.
As with the previous feature, it isn't finished and may result in some bugs.
Unused Trainer Battles
There are several unused trainer battles in the game. Most of them are dummy battles where the enemy only has one level 5 Ekans. But a few have real teams and some of them are cut trainers that existed in Red and Blue. For example there is for every Ruby and Sapphire trainer battle sprite a trainer battle in the game. To experience the battles in-game the following address has to be freezed to the desired Trainer Battle ID and then any trainer battle has to be initiated.

There's more source paths, and more interesting text.
Near the build date info is a plain-text string showing the build path and a few build variables. The Japanese 1.0 revisions use relative paths instead of the full paths, both English revisions (1.0 and 1.1) have this line in full, and the Japanese 1.1 revisions no longer have this information.
- FireRed JP 1.0 (location 1CDE8A) and LeafGreen JP 1.0 (location 1CDE66):
../gflib/malloc.c 0 p != NULL pos->magic_number == MALLOC_SYSTEM_ID pos->flag == TRUE pos->next->magic_number == MALLOC_SYSTEM_ID pos->prev->magic_number == MALLOC_SYSTEM_ID
- FireRed US 1.0 (location 1E9F68), LeafGreen US 1.0 (location 1E9F44), FireRed US 1.1 (location 1E9FD8), and LeafGreen US 1.1 (location 1E9FB4):
C:/WORK/POKeFRLG/src/pm_lgfr_ose/source/gflib/malloc.c 0 p != NULL pos->magic_number == MALLOC_SYSTEM_ID pos->flag == TRUE pos->next->magic_number == MALLOC_SYSTEM_ID pos->prev->magic_number == MALLOC_SYSTEM_ID
These changes apply to the English version of the games.
- Version 1.0 of the American release does not show "PRESENTS" on the Game Freak logo screen, although the tile graphics are present in the ROM. This was likely due to a bug introduced during the localization process, as the original Japanese versions do display this.
|US v1.0||US v1.1|
- In v1.0, species names in the Pokédex only display the first word due to the game incorrectly interpreting the space character as a null terminator. For example, Pidgey's species name is listed as "Tiny" rather than "Tiny Bird".
- In v1.0, Chikorita's FireRed Pokédex entry refers to its "leaves". In v1.1, the entry instead refers to a singular "leaf".
- In v1.0, Tyranitar has the same Pokédex entry in both FireRed and LeafGreen. In v1.1, Tyranitar has a new Pokédex entry in FireRed.
- In v1.0, the Pokédex help menu advises the player to select "AREA" to display a Pokémon's habitats on the Town Map. In v1.1, it instead advises the player to select "NEXT DATA".
