About This ROM Hack
Pokémon Custom Crystal is a difficulty and quality-of-life enhancement hack designed for players who enjoy a more refined version of Pokémon Crystal without the extreme difficulty found in hardcore hacks like those by Drayano.
The hack modernizes Gen II gameplay by improving movepools, adjusting type mechanics, reworking Gym Leader teams, and making most Pokémon obtainable, while still preserving the original structure and charm of Johto.
Story Overview
The main story follows the original Pokémon Crystal storyline across the Johto region, including the Elite Four and Champion. While the narrative itself remains mostly unchanged, minor dialogue edits have been made to freshen up interactions (though some may be buggy).
At the moment, the game ends after defeating the Elite Four and Champion. A future update is planned to fully implement Kanto.
Key Features
- Improved Pokémon Movepools: All non-legendary Pokémon have completely reworked movesets, addressing Gen II’s traditionally weak and unbalanced learnsets.
- Wider Pokémon Availability: Most Pokémon are catchable without trading, with encounter locations adjusted to account for buffs and balance changes.
- Type Mechanic Adjustments: Ghost-type moves are treated as Special, while Dark-type moves are treated as Physical, improving overall type balance.
- Gym Leader Team Overhauls: Gym Leaders now use updated teams, with many finally showcasing Johto Pokémon rather than relying heavily on Kanto species.
- Difficulty Rebalance: Battles are tougher than vanilla Crystal but intentionally less punishing than hardcore difficulty hacks.
- Dialogue Tweaks: Some in-game dialogue has been edited for variety, though minor bugs may occur.
- Quality-of-Life Improvements: Various subtle changes improve pacing and overall gameplay feel.
Known Bugs & Issues
- Some dialogue edits may display incorrectly or behave unexpectedly
- Kanto content is currently incomplete
- Minor balance quirks may exist due to widespread movepool changes
