Help Prof. Elm get out of gambling debt!

Description

Pokemon Crooked Crystal is a reimagining of the classic Pokemon Crystal, designed to enhance gameplay while preserving its nostalgic charm. For example, HM03 Surf is now a Key Item—the Lapras Suit—though a reusable TM for Surf remains available at the same time.

The story takes an intriguing turn: After losing a rigged bet on the Bug Catching Contest, Professor Elm mired in debt, refuses to pay Team Rocket. Tasked with raising a Pokémon to protect Elm, you’ll travel through Johto, earning Gym Badges, exposing Team Rocket’s corruption, and unraveling their deeper, more sinister plans.

This hack introduces a more diverse set of wild and trainer Pokémon, an expanded and intensified Team Rocket/Radio Tower plotline, added lore about Kanto’s limited map, and plenty more surprises in this more challenging version of Crystal.

Features

• All NPC dialogue has been replaced with silly nonsense. For example, Falkner thinks he’ll become a bird if he eats enough birdseed. The other Violet Gym trainers are worried about this
• All 251 Pokemon are available, including added storylines for Gen 1 legendaries
• An updated storyline that introduces additional wrinkles to Team Rocket’s plot, including an explanation for Kanto’s infamous limited map
