Binary Breakdown of TS2 .package files

[Orbit]

I was wondering if anyone could give me information about the binary code breakdown of TS2 .package files, and how I could edit them outside of SimPE by editing the binary code.  I also need to know the format of the binary-encoded characters.  For starters, I would like to use this information to edit the neighborhood names in the NeighborhoodManager.package.

What I used:

DBPF format in general: http://216.32.95.40/wiki/DBPF
String tables: http://216.32.95.40/wiki/STR
Packages (including compression): http://216.32.95.40/wiki/Packages
File format codes: http://216.32.95.40/wiki/InternalFormats

Remember, the string resources are compressed, so you're probably going to have to load and rewrite the entire file, not just overwrite the tiny bit of data you want to modify.
