Pokemon Crystal Inheritance ROM

Pokemon Crystal Inheritance is a GBC ROM Hack by dwg6m9 based on Pokemon Crystal in English. It was last updated on August 14, 2026.

Description

Pokemon Crystal Inheritance is a time-traveling adventure through Johto! When Ilex Forest is threatened, Celebi calls out for help. Can you go back in time to save Johto’s future? Use your knowledge of the world to craft pokéballs from new apricorns, discover Hisuian evolutions of Johto Pokémon, and explore Johto like never before. 

In historic Johto, you’ll see the power-hungry Emperor Mejimi and his generals Bobesh, Kensey, and Adrinna use a crisis to consolidate power. In modern Johto, you’ll confront Johto’s wayward gym leaders as they wonder how to cope with a changing world. Nothing is inevitable – what path will you choose?

Features

• New region: Historic Johto
• Custom Pokédex of 254 includes Sinnoh and Hisui Pokémon
• New apricorn system to craft new Pokéballs: Bub Ball, Herb Ball, Deci Ball, Jeze Ball, and Geode crafted from materials on the overworld.
• “Hidden Palette” system where NPCs can adjust your Pokémon DVs to take on unique palette and grant the corresponding hidden power.
• Emphasis on overworld puzzles exploiting time travel mechanic
• “Trick House” in historic Ilex Forest
• Two possible endings
• Three difficulty modes: Easy, where enemies have no EVs or items; Normal, which is a tough but fair challenge; and Expert, where bosses have full teams of 6 with coverage moves and even higher EVs.
