About the hack: Pokémon Crystal is a great game, but sadly it suffers from bugs and inaccuracies that are hard to initially notice. This hack fixes them but still retain the original feel and content of the game, which means this hack is more of a “patch” rather than a completely new game.

!!NOTICE!!

It is highly recommended to make backups of your saves when trying out a new release. Saving to the 2nd floor of a Pokémon center is advised for the best results.

3.9c is another small patch which addresses the following issues:

• Fixed an issue with incorrect overworld sprites (For real this time)

• Fixed an issue where a caught pokemon’s pokeball would be shown over the stats window after a level up

3.9 changelog:

• Dire Hit, Guard Spec, Gold and Silver Leaf are now included in the random rewards pool of Battle Tower.

• Fixed an incorrect check on the Master Ball Battle Tower reward

• Evolutionary stones and Link Cord now cost 4000 Pokédollars

• Hard Stone and Soft Sand are now slightly more common to be found by smashing rocks

• Twineedle can no longer inflict PSN on STEEL types

• Tri-Attack can no longer inflict BRN on FIRE types and FRZ on ICE types
