[Bug 46196] Beat Hazard 2: Missing country code and flag

https://bugs.winehq.org/show_bug.cgi?id=46196

--- Comment #3 from João Ferreira  ---
What would be the best way to derive a default GeoID?

1. Using locale would be straightforward, but plenty of users set this to their
language of choice (often en_US) regardless of where they're living;

2. Using timezone would be more accurate (though some TZs fit multiple
countries, this is relatively rare). We can get this through zone1970.tab, but
that's not portable;

3. Using a static default (en_US) and/or an environment variable (WINEREGION?)

Also, should this be set on load time (like the locale entries in the registry)
or at prefix creation?

I'm new to Linux development. I don't know what's the best practice for this!
