Pokémon Yellow beta

Pokémon Yellow is a special edition of the Generation I games. It introduced the friendship system, which was improved and completed in Pokémon Gold and Silver and has since become a staple of the core series. It also added other features, such as walking Pokémon, which are exclusive to Pokémon Yellow and Pokémon HeartGold and SoulSilver, and the Pikachu's Beach minigame. Some aspects of the game's initial design did not make it to the final release, either due to time constraints or due to its heavy reliance and basis on Pokémon Red, Green, and Blue.


Evolution levels

In a news article on Pokémon.com about upcoming Pokémon games, it was mentioned that Pokémon would evolve at different levels to what they would in Pokémon Red and Blue.[1] However, the game had already been released in Japan at the time, so this may have just been misinformation.


Hidden battle system

Data exists for a battle situation when the Trainer has no Pokémon, though it isn't actually used when entering a battle with no Pokémon in the final release. In this case, selecting any option other than Run shows the message "Hurry, get away!" This may have been a prototype for the initial battle with the wild Pikachu at the start of the player's adventure, as the player has no Pokémon at that point. It could also have been planned for a possible battle against a wild Spearow with Pikachu unable to battle, making it closer to the events of the anime.

Leftover music theme

An unused music theme has been encountered in the internal data. It is not known where it would be used, but it is possible that it relates to the aforementioned "no Pokémon" battle system. However, it is not stored in either the battle, overworld or cave soundbanks. It is located in the minigame and "special Trainer" (Jessie and James) soundbanks, where the Pikachu's Beach music is stored, which is partly why this track only exists in Pokémon Yellow.

It may be worth noting that it closely resembles the battle music theme with Madake from BUSHI Seiryūden: Futari no Yūsha for the Super Famicom, a game that Game Freak developed and released in January 1997 after the release of Pokémon Red and Green, but before the Japanese release of Pokémon Yellow.

Scrapped Pikachu's Beach bonus score

The unused +750 points score

There is unused radness data for a score of +750 points in the Pikachu's Beach minigame. It is impossible to achieve this score, regardless of how many flips Pikachu does, or how they were performed.

Unused in-game trades

The Butterfree-for-Beedrill in-game trade Pokémon Red, Green, and Blue remains.[2] The Japanese version of Pokémon Yellow kept the name from the Japanese Blue while the English version renamed it to Stinger.

Two additional in-game trades were also planned but scrapped, probably to compensate for the removal of the in-game trades in Cerulean City and Vermilion City. They are of a Pidgeot for Pidgeot trade while the other is of a Mew for Mew trade. In the Japanese version of Yellow, both received Pokémon have the same nickname, まつみや Matsumiya; however, in the English localizations, Pidgeot is nicknamed Marty while the Mew is nicknamed Bart.

Default player and rival names

The unused default names for Red (Ninten) and Blue (Sony) remain unaltered.[3] In the Japanese version, Blue's unused default name remains unaltered from Pokémon Blue while Red's was subtly altered by gaining an extra digit (ゲーフリ1).[4]
