Here's a 3dn file for Castlevania II - Simon's Quest. Let me know if there's any trouble downloading, I've never used OneDrive before. Thanks!

Edited up to the first mansion. Lots more to do, I'm sure what I've done could be improved so feel free to download and fix it up!

Edit: Here is the password for where I am in the game, at the start of the first mansion. Simon has holy water, dagger and chain whip.
