How it works

The tools run entirely in your browser. The logic is checked, case by case, against the project's Python version, which is tested with real Pokémon: what you see here is what the game would do.

The game rules come from FireRed's reconstructed source code (pret/pokefirered), built as the Switch version. Species, move and item data are read from the compiled ROM itself, not typed in by hand.

What it is and what it isn't

• It's free, open source (AGPLv3, code on GitHub) and made by fans, run by Beater Studios. Contact: studiosbeater@gmail.com.
• It isn't affiliated with Nintendo, The Pokémon Company, Game Freak or Creatures.
• It doesn't use official logos. The item and ribbon icons come from PokéSprite and the region map from The Spriters Resource, credited on Credits; the other icons are our own drawings. Pokémon, FireRed, LeafGreen, Ruby, Sapphire and Emerald are trademarks of their respective owners.
