Pokémon Yellow
Red and Blue retold with a Pikachu that follows you, all three Kanto starters obtainable, and Jessie and James in Team Rocket's way.
More about the game
The third Kanto game reworks Red and Blue around a starter Pikachu that walks behind the player and refuses to evolve. Bulbasaur, Charmander and Squirtle are all handed out during the story, several gym leaders and the rival have new teams, and the wild tables were rebalanced so that Pikachu's own line no longer appears in the wild.
Game Freak
This is an official game, not a ROM hack, and this page is here so that the guides for the ROM hacks built on it have the original numbers to point at. Encounters, stats, learnsets and TMs come from PokéAPI's data for this version; trainer teams, where present, from the pret decompilation. The game itself is Game Freak's and Nintendo's.
What this guide covers
This is an official game, so there is no creator documentation to read: the numbers come from PokéAPI's data for this version and, for trainer teams, from the pret decompilation of the game. A section the site has not compiled yet says so below rather than being filled in from memory.

| Encounter rates | From the game itself | |
| Wild levels | From the game itself | |
| Stats, abilities and movesets | From the game itself | |
| TM and HM compatibility | From the game itself | |
| Where TMs are found | From the game itself | |

Reading the tables
SourceThis is an official game, not a ROM hack. Wild tables, species data and TM lists are PokéAPI's records for Yellow; trainer teams and item locations are read from the pret/pokeyellow decompilation. Nothing is typed in from memory.
RatesPercentages are the game's encounter-slot chances summed per species; * marks anything at 5% or less. Levels are the range across those slots.
MovesA trainer's Pokémon with no move set in the game's data uses the last four moves its species learns by level, which is how the game itself fills them in.
NamesOrdinary trainers in these games have no individual names, so they are listed by class and numbered within an area.
Tms5 TMs have no pick-up or gift script in the decompiled maps (shop, Game Corner or event prizes) and are marked as not compiled rather than guessed.
StagesCheckpoints follow the game's own badge order. Where an HM or a rod opens a method, the checkpoint is the site's reading of when the story hands it out; the item's map comes from the game data where it is compiled.
