|Pokémon Yellow: Special Pikachu Edition|
Also known as: Pocket Monsters: Pikachu (JP)
This game has unused areas.
Pokémon Yellow is the updated companion game to Pokémon Red and Blue, which incorporates elements of the series' eponymous anime.
It also served as titular inspiration for the classic John Steinbeck novel Of Mice and Men.

All the unused data from Red and Green and Blue remains in the code of Yellow, virtually all of it unchanged aside from a few exceptions, which are documented below:
Despite remaining unavailable in regular gameplay, the unused Butterfree-for-Beedrill in-game trade was modified slightly, with the received Beedrill having its English nickname changed from "CHIKUCHIKU" to "STINGER".
Debug Pokémon Party
The debug function that gives the player a set team of Pokémon saw its selection slightly tweaked, giving Yellow the following:
- Snorlax: Level 80 (Debug Rom: Level 80, Moves: Fly, Cut, Surf, Strength)
- Persian: Level 80 (Debug Rom: Level 80, Moves: Screech, Pay Day, Fury Swipes, Slash)
- Jigglypuff: Level 15 (Debug Rom: Level 15, Moves: Sing, Pound, Disable)
- Pikachu: Level 5 (Debug Rom: Level 5, Moves: Thundershock, Growl, Surf)
Main article: Pokémon Red and Blue
There are multiple unused voice clips for the player's starter Pikachu.
|11||File:Pokemon Yellow-Pikachu Cry 11.ogg||Pika!||Excited|
|12||PI pika chu!||Incensed|
This unused track is present only in Yellow, and is located in the sound bank used by the game's extra features, including the "Pikachu's Beach" minigame. As revealed in leaked asset files, this theme was actually meant for Giovanni. Given the track's short loop, this tune was more than likely meant to play when the player talks to him before a battle.
Unused Stereo Mixing
Normally, the game initializes the various in-game options when first booting the game and just before loading save data. However, if the game's audio is forced into one of the three Headphone (stereo) modes before the introduction plays, the introduction song is revealed to have stereo mixing, just like all the other songs in the game.
Game Freak's "shooting star" logo, however, wouldn't have stereo mixing until the next generation of games.
Unused GB Printer Function
If the Game Boy Printer is properly connected, then calling address
3A:4E79 (referred to as "PrinterDebug" in the game's disassembly project) will mute the game's audio and attempt to use the printer to print a copy of the screen. For unknown reasons, if this is done on the overworld this will also glitch out the arrangement of tile blocks on the map, though the player can Fly/Teleport away if the original map was a normal town/route; otherwise, setting
D366 ("wCurMapTileset") to
0x00 will allow the player to escape.
Unused Encounter Type
Encounter types in Pokémon Yellow are defined by a single byte, with all used types including standard wild Pokémon encounters, those that take place in the Safari Zone, and the encounter initiated during the Old Man's Pokémon-catching tutorial. Encounter type
03, however, goes unused. In this mode, attempting to fight, access the item menu, or switch Pokémon triggers the unique message "Hurry, get away!". The player thus has no choice but to run, though fortunately the chance of escaping from this encounter type is hardcoded to always be set to 100%.
Because this encounter type only exists in Yellow, it may be that players would once have had the option to obtain their own Pikachu beyond the walls of Pallet Town, rather than being forcibly gifted one by Professor Oak before leaving. In this scenario, an encounter mode in which players were forced to escape if their party was empty would be essential for preventing the player from sending out an invalid Pokémon.
To force this encounter type, input GameShark code
010359D0 and then trigger an encounter.
Unused Radness Bonus
The minigame "Pikachu's Beach" has an unused "radness" bonus of +750 points, identifier
0x04, which isn't assigned to any number of flips, be they regular or "special" (forwards-backwards). This unused set bonus can be accessed by inputting the GameShark code
Unused Trade Data
In addition to the unused trade from Red and Blue, Yellow went ahead and added two more unused in-game trades, possibly placeholder data related to the removal of the in-game trades in Cerulean City and Vermilion City. These two unused trades would allowed the player to trade a Pidgeot for Pidgeot and a Mew for a Mew, with both of the received Pokémon having the nickname まつみや (Matsumiya, presumably after Toshinobu Matsumiya, who is listed in the credits of Yellow under Game Scenario). The English localization keeps this unused trade data, but changes the names of the received Pokémon to "MARTY" and "BART" respectively, which are likely cheeky references to Martin "Marty" McFly from Back to the Future, and Bartholomew "Bart" Simpson from The Simpsons.
The trades themselves are fully functional and can be accessed by inputting the GameShark code found below and using the first glitch item in your bag. Replace "xx" with 02 for the Butterfree for Beedrill trade, 04 for the Mew for Mew trade, or 06 for the Pidgeot for Pidgeot trade, then use the first glitch item in your bag. Please note that this code also has some side effects: in all versions, the player's item data will be changed, and so will the stored Pokémon data.

Unused Catch Rates
Pokémon Yellow was programmed with a few special considerations to take Generation II's Time Capsule in account, which will translate a Pokémon's catch rate into a held item when transferred. As such, Dragonair and Dragonite's catch rates were lowered from 45 to 27 (Dragonair) and 9 (Dragonite), which makes them significantly harder to catch, though neither of the two Pokémon can actually be encountered in the wild in Red and Blue. In addition, this changes their held items from a Bitter Berry in Red/Blue to a Protein (Dragonair) and Antidote (Dragonite). While Dragonair can be found in the wild in the Safari Zone in Yellow, there is still no way to have a wild encounter with a Dragonite during normal gameplay, leaving its catch rate and subsequently its held item to go completely unused.
Game Freak Tiles
While these tiles are used in the Japanese version during the "Game Freak" portion of the intro, they never show up in the localized versions despite still being found in the VRAM. The exact same thing also happened back in Red and Blue.
The localized title screen features a grand total of four unused tiles. The two rightmost ones are identical to the lower end of the "N", but are lower than the corresponding tiles. The leftmost tile, meanwhile, fits perfectly under the "P", a spot already occupied by the "YELLOW" tiles. The middle tile, meanwhile, is rather interesting, as not only does it fit in the blue portion of the "N", but it is directly placed there in the VRAM, only to oddly go unused in the final logo.
|Unused Frames||Animated Sprites|
Officer Jenny has a full set of walking sprites, though she never walks at any point during the game.
The Bulbasaur in Cerulean City is completely stationary and has its back right against a wall, preventing the player from interacting with it from behind and leaving its back sprite completely unseen.
The Chansey found in the Pokémon Center and the Fuchsia City zoo are completely stationary, leaving their back and side-facing sprites to go unused. These sprites can technically be seen in-game, though it requires making use of the off-screen Pikachu glitch.
The minigame "Pikachu's Beach" features a few unused sprites:
Two unused sprites of Pikachu on its surfboard, one front-facing and one back-facing. In the final game, the only time that Pikachu faces a direction other than left or right is on the result screen, and even then it isn't on the surfboard.
As it turns out, the unused flower tile from the previous games actually makes a return here, but this time it can now also be found in tileset
00, instead of only tileset
07. Just as before, however, it still gets overwritten in-game, meaning you never get to see it in action.
The tileset for the Summer Beach House on Route 19, despite being incredibly limited, somehow managed to feature two unused tiles. These two tiles are the ones which make up the white rectangle which also goes unused in Tileset 01 and 02. These tiles do not appear in any of the map's blocks.
The unused blocks from tileset 00, still as unused as before, but now with updated graphics.
- Naked wall duplicate (03) (used is 05).
- Messed-up blocks (04 and 08). Respectively the bookshelves and staircase blocks in Blockset 01, as Blockset 19 was built upon it.
- Standalone cushion (0E). Standalone chair in Blockset 01.
- Full wall block (11 to 13). Used as padding.
The string brought up by the unused encounter type. Found right after the standard "Got away safely!" string.
|はやく にげるのじゃ！||Hurry, get away!||Vite! Fuyons!||Schnell weg!||Via, presto!!!||Deprisa, vete!|
Would have likely been uttered by Bill if you tried to leave his house without helping him revert back to his human form. In the final game, you can leave the house at any point without anything dissuading you. Found right before Bill's "I'm a POKéMON..." string.
|なんや どこ いくんや！
|Whoa, don't go
|Hé! Attends!||Hey, lauf nicht
|Ehi tu, fermati!||¡No te muevas!|

|This article is a work in progress.|
...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes.
Notes: This page is undergoing reorganization.
Pokémon amarillo es la version actualizada y acompañante a los juegos Rojo y azul,que incorpora elementos de la serie homónima' .
y tambien sircio como inspiracion en la clasica novela de John Steinbeck Of Mice and Men.
gritos sin usar
aqui tenemos multiples gritos y voce para el pikachu acompañante del jugador que nunca se usan. esas voces fueron hechas por Ikue Ohtani, la acttris que le ad voz a pikachu en la version japonesa del anime de Pokémon . De 42 gritos, 16 no se utilizan. El estado de ánimo, por supuesto, está abierto a la interpretación del oyente.
These two strings are assigned to the two other unused trades, with "Marty" being assigned to the Pidgeot and "Bart" being assigned to the Mew.
A string which is only ever used in the case of a memory error. Found right before Professor Oak's opening lecture.
|Not enough Yellow
|Es ist zuwenig
The two screens which precede the opening cutscene were changed during the game's localization. In the first, the copyright dates were updated. As for the "Game Freak presents" screen, the "presents" graphic doesn't appear for some odd reason, despite it still being found in the VRAM.
Title Screen Changes
The title screen had the logo changed to its international equivalent, the "POCKET MONSTERS" subtitle was removed, the copyright dates were updated, the "Yellow Version" subtitle was added, and the speech bubble was not only repositioned, but its contents were also changed from a stylized "ピカチュウ" (Pikachu) to a simple "Pika!". Border-wise, "POKEMON PIKACHU" was unsurprisingly changed to "POKéMON YELLOW".
A lot of the changes which took place in Red and Blue still apply here. For example, while the overworld tileset was updated for this version, all the tile changes which existed in Red and Blue still apply to their respective localizations. Meanwhile, the town map screen features the same differences between the Japanese and International versions.
The v1.3 release of Japanese Yellow, also known as "Rev 3", fixes a bug in which having Pikachu stand on one of the boulder switches in Victory Road will remove its corresponding wall tiles (as if the player pushed a boulder on to the switch) for all boulder switches but the one found in 1F. This fix was carried over to all localized versions of the game.
Virtual Console Release
Which version of the game players were able to access via the Virtual Console depended on which region they were in. Japanese players got the original Game Boy version, whereas audiences in other countries got the Game Boy Color version. Because the Japanese VC release is locked to Game Boy mode, its Super Game Boy enhancements are inaccessible. Likewise, because the international VC releases are locked to Game Boy Color mode, both their Super Game Boy borders and their monochrome Game Boy mode are completely inaccessible.
Jynx's sprites in the International Virtual Console re-release were updated to match the Pokémon's updated skin color. While the sprite seemingly appears to use five colors instead of four, something literally impossible for a Game Boy Color game, this effect was simply achieved thanks to some of the 8x8 tiles composing the sprite being assigned an altered palette where black is replaced with purple.
|International GBC||International VC|
The following move animations were changed slightly to avoid rapid flashing; as usual, this is to comply with current seizure protection standards.
- Dream Eater
- Hyper Beam
- Mega Kick
- Mega Punch
- Rock Slide
Game Boy Printer
The option to print Pokédex entries using the Game Boy Printer was disabled on the Virtual Console. Other Game Boy Printer features were left unmodified, though this means little, as the Game Boy Printer cannot be connected to the Nintendo 3DS.
Wireless trading was included in the Virtual Console release via the use of a modified emulator that spoofed the Link Cable without affecting the ROM. Moreover, the line "The link has been closed because of inactivity. Please contact your friend and come again!" was changed to "Please come again!"
The Pikachu's Beach minigame was made available to the player's starter Pikachu regardless of whether or not it knows Surf. However, the three posters in the Summer Beach House are still programmed to only give the player surfing tips if their party contains a Surfing Pikachu.
