Basically, it's not compressed nor encrypted, and at the beginning of the file (let's call it LUX), there's two values: a pointer to a file listing and a file count
The file listing has entries that are 0x60 bytes, and only identifiable values I could find are addresses and length. File names have file types prefixed instead of suffixed
Recognizable file types include: DDS, XML, INI, differently formatted text files, and Fmod banks

(sidenote, apparently all those data.so_coms are cmd dir logs)
The main project repo is here: https://github.com/donnaken15/HydroMod
Soon, it will have the ability to replace files or erase them, without going over the original file size, if that will even be the case
I also just made a QuickBMS script for this thing:

but it might just be obsoleted by this program.
The issues I'm having to face now is:
- Why the game crashes to change the entire LUX's size or a file entry's data address
- How file names work, because a short file name has random bytes right in front of it instead of zeroes
- How mesh files work. At the near end of these files, there appears to be valid float values (with some repeating in one case)
