I knew I once downloaded one from somewhere, but I have since deleted it and I can't remember where I got it.

But it seems you're in luck, I checked a backup of that runtime and there it was. Couldn't find a readme for it, but from a name on a texture I traced it to this site:

If the download doesn't work let me know and I'll send you the files I have for it.
