About This ROM Hack
Pokémon Refined Crystal is a focused reimagining of Pokémon Crystal that addresses one of Generation II’s most common criticisms: the overwhelming presence of Generation I Pokémon in Johto. Rather than altering the core mechanics or tone, this hack refines the original experience by redistributing Pokémon encounters to properly highlight Generation II’s own roster.
The result is a Johto region that finally feels like it belongs to Gen 2, while fully preserving the original gameplay systems, progression, and post-game content that made Pokémon Crystal iconic.
Story Overview
The storyline remains identical to the original Pokémon Crystal. Players begin their journey in New Bark Town, receive a starter from Professor Elm, challenge the Johto Gym Leaders, defeat the Elite Four, explore Kanto, and ultimately face Red.
What changes is not the narrative, but the world itself. Johto is no longer saturated with familiar Gen 1 encounters; instead, it showcases the full variety and personality of Generation II Pokémon throughout the entire adventure.
Key Features
- Generation II–Focused Pokédex: All 100 Generation II Pokémon (and closely related evolutions) are obtainable, with encounters redistributed across Johto for variety and balance.
- No Gen 1 Filler Encounters: Common Gen 1 Pokémon have been removed from most routes, ensuring Johto feels distinct and fresh.
- Complete Crystal Experience: Players can defeat the Elite Four, explore Kanto, and battle Red, just like in the original game.
- Reworked Trainer Teams: Gym Leaders and trainers now use more appropriate and interesting lineups, such as Falkner no longer relying on Pidgey.
- Preserved Gen 2 Mechanics: All original Pokémon Crystal mechanics, systems, and balance philosophies remain intact.
- New In-Game Trades: Additional NPC trades have been added or relocated to improve accessibility.
- Starters in the Wild: Johto starter Pokémon can now be found naturally during exploration.
Known Bugs & Issues
- Celebi uses an incorrect overworld sprite (Jynx), causing unintended movement behavior
- Some Pokémon-trading NPCs in Kanto are missing or relocated to Johto
- Minor inconsistencies due to the project’s early-development nature
