I was able to reverse engineer the PS4 edition of "New Game!: The Challenge Stage", which was never released in English. I've now fully translated it, added proper text wrapping and additional text boxes where text would now overflow. Along the way I've fully decompiled (with byte exact recompilation) the Squirrel scripts for the entire game, built atop the game engine of a now largely defunct game studio. Prior to this I hadn't even heard of Squirrel scripting language. I had most of this done in under 24 hours.

I'm not in any way a part of the visual novel community. I just did this because I enjoyed the New Game! anime way more than a near(?) middle aged man probably ought to.

P.S. My condolences to Yorhel's friends and family.

Interactive fiction has https://ifdb.org/.

Gamebooks ("CYOA" to outsiders) have https://gamebooks.org/.

I think there is some community around branching browser text stories like (mostly) Twine games that have their own database somewhere?

And then there is always some overlap and discussions around what games to allow where, with each community gatekeeping to some degree what games are allowed in their database or not.

So, for example, I never heard about VNDB and never really crossed paths with VN players online, even if I have been around communities for IF and gamebooks since last century and the similarities are obvious.
