Pokemon Crystal - Curse of the Unown King ROM

Pokemon Crystal – Curse of the Unown King is a GBC ROM Hack by OxygenTheSmolAngel based on Pokemon Crystal in English. It was last updated on March 23, 2026.

Description

Pokemon Crystal – Curse of the Unown King is a somewhat faithful recreation of the Curse of the Unown King creepypasta from the beginning to the end, with some creative liberties taken to make the experience a bit more fresh for those who’ve read the creepypasta before. The base game itself is left as is, with the new content put on top of it. So you can basically play this as if it was a normal copy of Crystal or go for the main content hidden from plain sight. The choice is yours!

Features

• Main content hidden in the game, but still accessible
• Base game left intact with some modifications. The new stuff were added on top of it.
• Original creepypasta fully recreated with minor removals and some major changes.
• It imitates an existing hacked save file, emphasizing the fact that the original owner of the save is a cheater (Many vanilla progression flags are set while others aren’t.)
• An optional bonus event (Hint: Maybe go check out Celadon City?)
• You can now reset the in-game clock by interacting with the bed in your house (Uses the Initialize Clock script from the vanilla game’s intro.)
• Code is open-source, so you can use it in your ROM Hacks (with credit, of course.)
• Will be updated over time to fix bugs and maybe add some new bonus content(?).
