The CentriScid_ID tag is a key. It is sufficient to designate a game. The
version n+1 superseedes the previous one. If you use (version, Id) tuple as
a key you consider several distinct games, from a DB point of view.

I was not aware of this. Do you have enough RAM related to the size of the
base ? My main concern here is that I'd like to have something easy to
implement, and to add a metadata file along with the 3 existing files is not
a piece of cake.
