Pokémon Serene Crystal is a hack that strives to change up the original Crystal, with new gym leaders and Pokémon from newer generations, alongside new original regional forms! There have been several QOL improvements that, alongside the new dex, makes for a fun experience! While the story remains largely unchanged, there have been a few minor changes to make some characters feel more coherent. Apart from that, it’s identical to Crystal’s story.


  • A remixed Pokedex, both of old and new Pokémon.
  • Better balancing, with a “fixed” level curve (I tried).
  • 2 new gym leaders, replacing old ones, and an older gym leader has been promoted to a higher gym.
  • HMs can be forgotten at anytime.
  • A lot of Pokémon have had their sprites changed.
  • Various QOL changes, such as being able to run, Pokémon not dying of poison in the overworld and evolutionary stones being available for purchase in Goldenrod.
  • A rebalanced type chart, aiming to buff weaker types, and slightly nerf stronger types.
  • Several weaker Pokémon have gotten stat buffs, and all Pokémon have better movesets. All Pokemon have also had their stats updated to match Gen 7, with the exception of Raichu.
  • Every Pokémon can be evolved without the need for trading. Trade items can be used like stones.
  • There’s no badge boost anymore.
  • The Super Rod will be available in Blackthorn city.
  • Several moves from newer generations have been added.



  • Bug fixes:
  • The entrance to Mount Moon has been blocked off from Cerulean City as before. This means the only way to get to Pewter City is through the Sleeping Snorlax and Diglett Cave. This is to prevent the player from being challenged by Silver, as the interaction is bugged if entering the cave through that side.
  • Interactions with Sage Li should now be fixed.
  • Absol’s Pokedex entry is now fixed.
  • Apricon balls function as intended.
  • Burn, paralysis and poison now affect the catch rate.

    Visual changes:
  • Every Pokemon has a unique menu sprite!
  • The Kabuto and Omanyte in the Unown chambers have been replaced with Phanpy and Chinchou, respectively.
  • Granbull’s sprite has been adjusted, it now uses the Silver sprite as a base.
  • Bombirdier’s, Typhlosion’s, Politoed’s & Floatzel’s front sprites have been fixed.
    Bombirdier’s, Basculin’s & Espathra’s back sprite has been adjusted.
  • Slowpoke’s, Onix’s and Horsea’s shinies have been adjusted.
  • Cottonee, Yamask, Cofagrigus, Milotic, Luvdisc and Alomomola have all had their footprints fixed. They no longer show up as a white box.
  • Ending screen has new graphics!

    Gameplay changes:
  • Added the Move Reminder to Blackthorn!
  • Added Elite 4 + Champions rematch teams to fight after 16 badges have been obtained.
  • Blackthorns layout has been changed slightly. Please go to a Pokemon Centre before downloading the patch to avoid being stuck in walls.
  • The Stones are no longer available in Goldenrod, they have been moved to the Olivine mart.
  • The sick Miltank only requires 3 berries instead of 7 to become fully healthy.
  • Items mom buys have been lowered in price, meaning you’ll lose less of your saved up money when she buys something.
  • Cianwood’s Phanpy Puzzle has been removed, and replaced with a hopping puzzle. I was unable to have the game keep the floors open after completing the puzzle, thus I decided to remove it.
  • Shiny odds have been decreased. Shiny Pokemon that you’ve found before may now not be shiny anymore. Sorry about this inconvenience. (~1/128 > ~1/1024)

    Rock no longer resists Ice.
