v3.2 is now live! 🎉 It'll take some time for this wiki to get up to date.

Welcome to the Polished Crystal Wiki!

This is a community-driven wiki for Polished Crystal — by players, for players.

Not all information might be entirely up to date by nature. The only fully accurate, fully up-to-date information is the source code in the repository. (If a Development Rolling Release exists, the master branch will track it. Browse the repository with care.)

Make sure to read the official README and FAQ:

If you have a question about playing Polished Crystal, or think you've found a bug, please read this FAQ first.

— Polished Crystal dev team, FAQ.md

General Gameplay Notice

Read the official Releases page carefully. It also links to the save patcher for upgrading your save files from older versions. As of Dec. 2025, the latest official build is v3.2.3, tagged as Latest on GitHub.

Some additional notes:

  • A few new side quests may only be teased in-game; those areas are works in progress.
  • The game requires accurate emulators shown on Releases and FAQ, particularly because some emulators (and their save-state function) are incompatible with the new Pokémon Box and corrupt it.
  • It's impolite to ask the devs for the estimated time of arrival (ETA); that's a general rule for fan-games, as they don't revolve around schedules or deadlines. Follow the #development channel in the Discord server.
  • About older versions:
    • v2.2.0, finished in Sept. 2016 (and tagged as such in 2017), is obsolete and out of support; the upgrade of v2.2.0 saves is unavailable.
    • What was called 9bit became v3.0.0.

Known Issues

  • In some corner cases with the full party, receiving Mr. Pokémon's gift crashes.
  • Eusine's words and deeds may ignore your progress on the three Beasts.
  • The roaming Beasts fail to play their encounter theme.
  • Pokémon move learnsets aren't fully updated to Gen. IX+.
  • A few Trainers have a team of horrible movesets.
  • There are a few corner cases in Mold Breaker.
  • The special-gift Shiny Togepi may max out its PPs in an inconsistent way.
  • Some NPC-given items may be lost when the Bag is full.
  • Mails are banned during Link Trades (to prevent potential corruptions).
  • There may be minor graphical issues.

Info for Testers

If a Development Rolling Release exists, it won't be intended for public playtesting but for the development purpose. Ask the devs about playtesting if you wish to help them.

Info for Cheaters

Use the save editor linked below (instead of GameShark cheat codes or PKHeX). Avoid asking the devs for cheat codes.

The devs have been concerned about false bug reports caused by cheating. Cheat codes overwrite a specific data byte, so using incorrect or outdated ones not only fails to work but also corrupts your game/save:

  • This game's data structure is significantly different from the vanilla's; so PKHeX is incompatible, and vanilla codes are highly likely to cause corruption.
  • Due to its active development, the game may often reorganize its data, which outdates cheat codes quickly.

For those interested in more complex cheating:

  • Read the .sym file guide to learn how to generate valid cheat codes;
  • Use your emulator's hex editor; or
  • Clone the repository to code and create a custom build.
