If you have a question about playing Polished Crystal, or think you've found a bug, please read this FAQ first.
At the time, I was asking really obvious questions like: "So 'wireless' means you're getting rid of the wires, right?"

The 3.1.0 release provides .gbc files and .sym files. You only need a .gbc file to play; they're ROMs, not patches. I recommend playing polishedcrystal-3.1.0.gbc
, or polishedcrystal-faithful-3.1.0.gbc
if you want a more faithful canon experience, without changes to Pokémon base stats or types.
Don't download the debug ROMs; they're for beta testing, not start-to-finish playthroughs. Although if you want to help test for bugs, get a debug ROM, talk to your room's radio to unlock many things, and hold A+B to walk through walls.
The 2.2.0 release is not recommended for general play (it is very old, and not the latest stable release). Only make use of this if you have an existing 2.x save and don't want to start over, since 2.x saves are not compatible with version 3.0.0 and above.
This is the ROM you should use for patching 2.2.0:
- Pokémon - Crystal Version (UE) (V1.0) [C][!].gbc
(
md5: 9f2922b235a5eeb78d65594e82ef5dde
)
It's identical to the one built by the pokecrystal project.
The .sym files are created when you build Polished Crystal. They list the memory address of every label in the source code. These can be useful for discovering GameShark cheat codes. You can compare the addresses for Polished Crystal with the same labels for pokecrystal to find the equivalents of old Crystal cheats.
Cheat codes are not officially supported: new updates may change or break old codes, disable cheats before complaining that there's a bug in the game, and don't ask for pre-made cheat codes.
A wiki is provided with various info. For things not present in the wiki, the game's data files do a fairly good job of listing things you'll want to know. Some highlights:
You can also just use in-game features! The Pokédex has a lot more information, including base stats and detailed wild locations.
I like the anime explanation that red Gyarados was forced to rapidly evolve from a Magikarp and kept its previous red coloration. So here, red Gyarados is a variant form, with its own color and different sprite. It's shiny locked, meaning it can't be shiny. Shiny Gyarados are gold, like shiny Magikarp.
There's usually only a 1 in 4,096 chance to encounter a shiny Pokémon (which can be raised with the Shiny Charm or using the Masuda method), and they'll be marked with a star next to their name. You're probably noticing the effect of the IVs vary colors option (see below).
- Natures: Enables natures from Gen 3 onward.
- Abilities: Enables abilities from Gen 3 onward.
- Phys/Spcl split: Enables the Physical/Special split from Gen 4 onward.
- EV gain: Changes how EVs behave. You can choose "All", which allows maxing every stat, "510" which features the modern 510 EV limit, or "No" which disables their effect completely, and will also cause Tyrogue's evolution to depend purely on its IVs.
- Exp. scaling: Enables the experience formula from Gen 5, 7 and 8, which scales experience by the ratio of the opponent's level to your level.
- Affection bonus: Enables the modern Affection system, which can do things like make your Pokémon survive at 1 HP, cure themselves of status problems or evade attacks.
- Real-time clock: Enables the game to keep track of time even when you are not playing. Some cartridges or emulators may not support this. Disabling it will cause time to only tick when you play, and a day will last 4 hours.
- Perfect stats: All Pokémon stats, for you and the opponent, are calculated as if they had maximum IVs. The actual IVs are still random, so color variation and Hidden Power type are not affected. Note that this has no impact on EVs in any way.
- Traded PKMN obey: All differences in traded Pokémon go away: they always obey you, don't gain boosted experience, and can be nicknamed.
- Evolve in battle: Allows your Pokémon to evolve in the middle of a battle if their evolution conditions are met.
- Color variation: Enables color variation inspired by Stadium. DVs will subtly vary Pokémon colors. This applies to normal and shiny Pokémon.
If you need to change these options after starting a game, press Left+B at the title screen to reset them.
Having a built-in Nuzlocke Mode led to assumptions that the game catered specifically to the Nuzlocke community, and was balanced accordingly. The problem is that this led to a lot of people complaining that we didn't, for example, offer a built-in level cap or infinite Rare Candies. In the end, we chose to remove the Nuzlocke Mode option to make it clear that, while we have nothing against people doing self-imposed challenges, we have no plans to specifically design the game around them.
There's only room for 255 moves, including Struggle. I wanted to fit in as many useful new moves as possible, so some similar moves were combined to free up space.
- "Fury Strikes" = Fury Swipes + Fury Attack
- "Healing Light" = Morning Sun + Moonlight + Synthesis
- "Fresh Snack" = Softboiled + Milk Drink
Their animations in battle still depend on the Pokémon using them, e.g. Chansey's Fresh Snack looks like Softboiled, while Miltank's looks like Milk Drink. That's also the case for some moves that were consolidated: for example, Withdraw and Harden were removed, but Defense Curl has the animation of Withdraw for Squirtle, and of Harden for Geodude.
Here's a table of all the moves available in the 3.0.0 beta.
- Ask Lyra! She gives you her phone number when you reach the Day-Care on Route 34.
- Gen 1's trade evolutions now evolve by using the Linking Cord item.
- Item trade evolutions (like Seadra into Kingdra while holding a Dragon Scale) now evolve while holding the item.

- Eevee evolves into Leafeon in Ilex Forest, site of the Moss Rock.
- Eevee evolves into Glaceon in the Ice Path, site of the Ice Rock.
- Eevee evolves into Sylveon with a Shiny Stone.

- Articuno is in the Seafoam Islands.
- Zapdos is above the Power Plant after you fix the generator.

- Shiny Stones are in Cherrygrove Bay, Mt. Moon or National Park. Bill's grandpa also gives you one, and you can win one in Bug-Catching Contest in the morning.
- Bill's grandpa lives in Goldenrod City and gives you one of each Evolution stone. Also, certain trainers will call you up to give you stones, just like in regular Crystal. The Celadon Dept. Store sells several evolution stones and the Linking Cord.
Silver Leaves are like Shards in future generations: they can be given to Move Tutors to learn moves. Wild Oddish have a 50% chance of holding Silver Leaves, and there are some hidden on the ground in Ilex Forest.
Gold Leaves can be given to the Move Maniac in Cianwood City to relearn moves. Wild Bellsprout have a 50% chance of holding Gold Leaves, and there are some hidden on the ground in Yellow Forest.

Daily blessings in Ecruteak City and photographs in Cianwood City make your Pokémon happier, just like haircuts or grooming.
The Judge Machine in Goldenrod City's PokéCom Center shows your Pokémon's EVs (effort) and IVs (potential). To unlock it, breed at least one Egg and then talk to the engineer working on it.
Those are opened up after you catch all 28 Unown and talk to the scientist who gave you the Unown Dex.
I was hesitant to make original changes like this, because the goal is to be an improved Crystal version, not a new game. In the end I made two versions, one regular and one "faithful".
The regular version makes creative changes to Pokémon base stats and types, and to some move properties, mostly inspired by Drayano's Sacred Gold and Storm Silver. It also improves some translated terms that Nob Ogasawara complained about.
The faithful version does not change those things, besides updating stats to the latest canon generation.
