How to crack an encrypted XML file

As mentioned in the title, I found in localizing a game called "Ship Simulator Extreme Edition",
All the strings of the game are stored in XML files, try to open and modify, but it is garbled.
But when I entered the game, I found that he could load and display normally. I tried to use OllyDbg to analyze it, but I still couldn't analyze how he decrypted the XML file normally.
I used Google Translator to translate all the above words.

Those XML files are not encrypted, they are
compressed with ZLIB.
Here is the file format
http://wiki.xentax.com/index.php/Ship_S ... tremes_XML
You can decompress those files with offzip
http://aluigi.altervista.org/mytoolz/offzip.zip
Then you can open/edit output files with
Notepad++ and repack with offzip if you need.

Thank you for your reply, I successfully unpacked the XML file and generated it according to the .wdproj suffix. He edited it normally, but I can't compress the file at present, I don't know how to regenerate the XML file, can you tell me how to compress it Are they? Thanks!
I tried to use the -o command to generate the xml file, but the program reported an error.

You can use "
-r" option in offzip for reimport.
Here's some more info

I don't know which step I did wrong, I still can't generate the .xml file using the -r command.

I tried to pack it with the packzip program, but the .XML file generated in this way cannot be read properly by the game.

Ok, after I did what you did, I found a new problem, and the following error was prompted:

If you don't modify the .wdproj file this appears to import fine.

Try to
read more carefully error messages and the documentation.
The error says
the compressed data is bigger than the original one
so it means your new data
can't be bigger than original. That's just
how the quickbms and offzip work.
So just edit the file and keep the final result as
smaller or equal original.

Well, I understand what you mean, I really can't understand what this byte is. Even if Play is changed to Klay, the program will report that the new data is 0x2 bytes larger than the original data. I still think of other ways to deal with it.
