What makes it different

Gold and Silver's definitive version: Suicune's story, the Battle Tower, a playable girl, and animated sprites.

More about the game

The third Johto game. Crystal reworks the wild tables of Gold and Silver, moves the legendary beasts' story to centre on Suicune, adds the Battle Tower and the Odd Egg, and lets the player choose a female character for the first time. The sixteen-badge structure and the Mt. Silver finale are unchanged.

The original game

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.

Reading the tables

SourceThis is an official game, not a ROM hack. Wild tables, species data and TM lists are PokéAPI's records for Crystal; trainer teams and item locations are read from the pret/pokecrystal 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.

TimeJohto's wild tables change with the clock: a table labelled morning, day or night applies at that time; an unlabelled one applies all day.

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.

Tms6 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.
