Gensokyo Fantasy Diary, or 幻想郷幻想日記 (Gensokyo Gensou Nikki) is a Mystery Dungeon-like fangame by the doujin circle @N-Factory. I made an English patch for it so I'm sharing it here. I contacted the circle to work with them officially, and though I didn't receive a response, they give explicit permission to translate this game in their readme and even include documents on how to go about doing it.
If you need the game itself, you can purchase it
here on DLSite.
