--- Comment #5 from Artem S. Tashkinov  ---
In a perfect world it would be great if Wine supported/used some DB backend for
registry files. SQLite maybe? No idea if it works for registry though.

I remember Wine used to support native registry files at least for reading.
That would have been even better.
