Pokemon Complex Crystal (v1.33)

Introduction: Pokémon Complex Crystal is a comprehensive ROM hack of the official Game Boy Color game Pokémon Crystal. It is set in the Johto and Kanto regions, retaining the original story and visual style but overhauling the game's content and balance to create a more challenging and expansive experience.

Gameplay & Mechanics: The hack features a vastly expanded Pokédex with over 250 Pokémon available from the first four generations, including evolutions like Tangrowth and Mamoswine. It does not implement the Physical/Special split or add the Fairy type, staying true to the Generation II engine. The difficulty is significantly increased, with Gym Leaders and the Elite Four using full teams of six with competitive movesets and items, making it less suited for casual Nuzlocke runs. The day/night cycle and weekly events from the base game remain fully functional.

Key Features:

• Massive roster expansion, integrating Pokémon from Generations I, II, III, and IV into the Johto landscape with new wild encounters and trainer teams.
• Complete rebalancing of trainer AI, levels, and teams, providing a consistent and demanding challenge throughout the main story and post-game.
• Quality-of-life improvements including reusable TMs, the ability to run indoors, and the addition of the Running Shoes from later generations as a key item.

This hack is designed for players seeking a classic Johto adventure with modern team-building options and a rigorous test of skill.
