Pokémon FireRed and LeafGreen beta

During the planning and development stages of Pokémon FireRed and LeafGreen, several parts were going to be a part of the games. Some of them were dropped or changed, but some of those dropped concepts can still be found in the game's programming code.

Locations

More routes were planned for the Sevii Islands. However, each one of these routes that are still programmed in FireRed and LeafGreen is oddly called Sevii Isle (Japanese: ななしま Nanashima), suggesting that they are islands instead of routes. Interestingly, their Japanese name spells the word nana in hiragana (なな) as opposed to the katakana (ナナ) used for the Sevii Islands. Nonetheless, their Japanese name is the same as the Japanese name of the Sevii Islands, as the Japanese word 島 shima can translate to either island or isle.

The Sevii Isles found in the programming code of the games are Sevii Isles 6-9 and Sevii Isles 22-24. Sevii Isles 8 and 9 have fully coded map data, implying that they were scrapped very late in the game's development.

A records room like that in the Hoenn games has also been found, but cannot be accessed without the use of a cheating device.

A map of the interior of an unused house in Routes 19 and 23 has been found. It is programmed in on both routes and the usage for them is unknown. However, it is possible that the one in Route 19 is related to an originally planned comeback of the Pikachu's Beach minigame from Yellow, where its related Summer Beach House (Japanese: うみのいえ Sea House) is located.

Other locations

This section is incomplete.
Please feel free to edit this section to add missing information and complete it.
Reason: Which maps are actually unused as opposed to being hidden and used internally by the games during regular gameplay?

There are also other unused maps in the programming of FireRed and LeafGreen. Only few of them are complete and there are some that appear to be alternate versions of the maps in the final release. However, their purpose is unknown.

In addition to these maps, 18 more have been found. However, 17 of them don't have defined data and the other has an invalid pointer to it.

Items

Key items exclusive to Ruby and Sapphire (and also Emerald, although it was released after FireRed and LeafGreen) are found within the programming code, complete with item sprites and in-Bag descriptions that differ from those of Ruby and Sapphire, due to their different layout and menu setup, which allows less space for the descriptions. These items are obtainable only by cheating or modification of the programming code. For the most part, they have no use, though the Mach Bike and Acro Bike will act the same as the normal Bicycle obtainable in FireRed and LeafGreen with the exception of not being recognized by the games for entering Cycling Road.

HM08, unobtainable except by cheating and containing Dive like in the Hoenn games, can be taught and deleted freely, making its use almost the same as a normal TM.

Text

In the localized releases of FireRed and LeafGreen, the text of dialogues is colored depending on the person's gender: blue for males and red for females, while other text remains in the usual black. In the original Japanese versions, no such distinction is made, thus all text is colored black. However, in pre-release footage shown on a Japanese commercial for the games, titled Pocket Monsters: Firered & Leafgreen (Japanese: ポケットモンスターファイアレッド・リーフグリーン), and previously available on the Nintendo of Japan page for the games, this distinction is present even in the Japanese releases. The reason for this change is unknown. This different coloration for the dialogue text can been observed at the 34 second instant of the video.

Sprites

There is an earlier version of the sprite for Professor Oak that would have been used in the introductory part of the games. It was seen in the aforementioned Japanese commercial, which was uploaded to YouTube by user Japancommercials4U2 (link).

Unused overworld sprites of Mew, Raikou, Entei, Suicune, Celebi and Deoxys' Attack and Defense Formes have also been discovered in the programming code. Their use is not known but it is possible that they might have been planned for events.

Leftover weather effects

The same weather effects from Ruby and Sapphire are present in the coding of FireRed and LeafGreen and are listed below, although using the flashing intense sunlight weather effect causes the games to output a black screen if used on a map.
