How to define and copy the compression method?

Question

Data archiving

Hey! I ran into a problem, and I can't solve it for a very long time. :c.
I want to write my own localization for the game Papers Please manually (without using constructors, as they are very outdated and have not been working for a long time).
So... The problem is that the archive with the localization of some. language uses an incomprehensible compression method, and the game simply ignores other types of compression. Please help, I will be very grateful!

An example localization file is here: https://dropmefiles.com/YsPeq

Answer 1

It seems that the author of the game cheated and creates a directory inside the archive with the name "." (dot). This is how, for example, the files from here are arranged: https://3909.zendesk.com/hc/en-us/articles/3600532...
In many systems, the dot means the current directory, so it will not be possible to unpack and even more so pack such an archive.
Here they suggest renaming the directory inside the archive using 7zip.

Answer 2

I do not understand.
There is a zip, it contains a loc.csv file with text. What is the problem?

Answer 3

unzip -v ru.zip
Everything is compressed using the Stored method (i.e. no compression at all) and the headers indicate that pkzip 2.0 can be decompressed.
In addition, the names of all file paths are present /at the beginning.
