|Pokémon Yellow: Special Pikachu Edition|
Also known as: Pocket Monsters: Pikachu (JP)
|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 Yellow is the updated companion game to 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.

There are multiple unused cries or voices for the player's Pikachu companion. These voiceovers were done by Ikue Ohtani, the actress who played Pikachu in the Japanese version of the Pokémon anime. Out of 42 cries, 16 are unused. The mood, of course, is open to the interpretation of the listener.
|12||PI pika chu!||Incensed|
This unused track is present only in Yellow. It is located in the sound bank used by the game's extra features, including the Pikachu's Beach minigame. According to some recently leaked asset files, this theme was meant to play for Giovanni. Due to the tracking having a short loop, it's more than likely meant for when the player talks to him before a battle.
To listen to the track in-game, input the following codes on a GameShark, then access a different map:
Unused Encounter Type
Encounter types in Pokémon Yellow are defined by a single byte. Possible types include standard wild Pokémon encounter, those that take place in the Safari Zone, and the encounter initiated during the Old Man's Pokémon-catching tutorial.
Encounter type 03 is unused, however: 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. Fortunately, the chance of escaping from this encounter type is always 100%.
Because this encounter mode 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 Ash from sending out an invalid Pokémon. (In this case, the glitch Pokémon "3trainerpoké", who uses identifier 00 and whose moveset draws from unrelated game data incorrectly interpreted as move information.)
To force encounter type 03, input GameShark code 010359D0, then trigger an encounter.
Unused Game Boy Printer Function
If the Game Boy Printer is properly connected, then calling address 3A:4E79 (PrinterDebug in the Pokémon Yellow disassembly project) will make the game mute the 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, however, 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 Gift Pokémon Function
Pokémon Red and Blue feature a debug function that adds Pokémon to the player's party. This function is also present in every release of Yellow, adding the following:
- Level 80 Snorlax
- Level 80 Persian
- Level 15 Jigglypuff
- Level 05 Pikachu
Unused Pikachu's Beach graphics and text
The Pikachu's beach minigame is unique to Pokémon Yellow. It can be accessed by talking to the man in the house on Route 19, south of Fuchsia City, provided the player's party includes a Pikachu with the same O.T. and Trainer ID as the player, who also knows Surf. (In short, in order to be eligible, the player must have used Pokémon Stadium and Pokémon Yellow's cross-play capabilities to teach Surf to the original Pikachu gifted to them by Professor Oak.)
Additionally, GameShark code 013972D1 can be used to replace the first move of the first Pokémon in the player's party with Surf.
Its gameplay is similar to Excitebike: Pikachu has a limited amount of time (represented by hit points) to reach shore. Final performance is graded based on the amount of HP remaining, and the number of "radness" points that were earned by performing flips.
There are a number of unused graphics in the minigame that can be seen using BGB's VRAM viewer.
There are two sprites of Pikachu facing to the front and back while on the surfboard which do not seem to be used. Normally the only time in game when Pikachu faces in a position that isn't to the left or right is when it faces the front while off the surfboard.
The text "GOOD!" and "YEAH-". These may have been intended as compliments for good gameplay and/or successful flips.
There is 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). It can be accessed by inputting the GameShark code 0104D9C5.
Replace the video with screenshots if needed.
In addition to the unused Butterfree-for-Beedrill in-game trade from Red and Blue, Yellow adds two more unused trades, probably related to the removal of the in-game trades in Cerulean City and Vermilion City: Pidgeot-for-Pidgeot and Mew-for-Mew, respectively. In the Japanese Yellow, both received Pokémon are nicknamed まつみや (Matsumiya, presumably after Toshinobu Matsumiya, who is listed in the credits of Yellow under Game Scenario).
The English localization keeps the unused trade data, but changes the names of the received Pokémon to "MARTY" and "BART", respectively. The English nickname of the Beedrill from the original games is also changed from "CHIKUCHIKU" to "STINGER", despite still being unused.
The trades are actually fully functional and can be accessed with a GameShark code. 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 pack. Due note that the code has the side effects of changing your item pack items in all versions and stored Pokémon.

Unused catch rate
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 none of the two Pokémon can actually be encountered in the wild in Red/Blue, they can only be obtained by evolution or in the case of Dragonair, buying one in the Game Corner in Japanese 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 still is no way to have a wild encounter with a Dragonite; because of this, its catch rate and subsequently its held item go completely unused.
The Japanese Yellow was a Super Game Boy game, just like Red and Blue. Game Boy Color support was added to the international versions.
Main article: Pokémon Red and Blue
All the unused data from Red, Green, and Blue remains in the programming code of Yellow. There is a small change pertaining to the unused Butterfree-for-Beedrill in-game trade, however: its English nickname was changed from "CHIKUCHIKU" to "STINGER". It otherwise remains unavailable in regular gameplay.

| Not enough Yellow|
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 localizations of the game.
Unknown Dungeon Layout
Cerulean Cave (ハナダのどうくつ), known as Unknown Dungeon (ななしのどうくつ) in Generation I, underwent layout changes for every Japanese Generation I release. The first layout was used in Japanese Red and Green, which was changed for Japanese Blue. The latter was retained for Red and Blue's international releases. Both the Japanese and international releases of Yellow had a third, simpler, layout.
The three layouts are pictured below.
The 1F layouts in Red, Green, and Blue function as mazes: the player can encounter dead-ends, and has to find the correct ladder in order to proceed. The Yellow 1F has a route that's more linear and easy to navigate.
2F is the trickiest floor to navigate. While the ladders remain in the same positions in each of the three layouts, the maze around them differs.
The positions of B1F's items are different between layouts. However, each layout features a straightforward path to the final goal: a wild Mewtwo, lying in wait.
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 inaccessible.
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.
|International GBC||International VC|
In the international VC releases, Jynx's sprites were updated to match its Western coloring, made to reduce comparisons to blackface. Thanks to this alteration, Jynx has more colors in its sprite than any other Pokémon in the game.

There's a whole lotta words here, but not enough pictures. Please fix this.
The following move animations were changed slightly to avoid rapid flashing, as usual, to comply with current seizure protection standards.
- Dream Eater
- Hyper Beam
- Mega Kick
- Mega Punch
- Rock Slide
Pikachu's Beach Minigame
The Pikachu's Beach minigame has been made available to the player's starter Pikachu, regardless of whether it knows Surf. However, the three posters in the Summer Beach House are still programmed to give the player surfing tips only if their party contains a Surfing Pikachu.
The message "The link has been closed because of inactivity. Please contact your friend and come again!" is changed to "Please come again!"
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.
