Best Guesses from tinkering so far (For people who haven't touched the goods yet): * Codes such as 0x05879d94, most of them seem to be a form of localization redirection. If you unpack the data package and then the en_us package in locale, you will see the code, then the words in english. * Cool hints from the people who made the game so far found: Found when unpacking the UI folder in the locale en_us. Will continue to explore. If what I understand so far is true ( Maybe not) Spore could potentially be very moddable.
