It smells of encryption because there is no clear data at the beginning or end of the archives.

I hope it helps and Aluigi can make a script for this game

GGDump is a tool for listing and extracting files from data archive files of the game Thimbleweed Park, which you should totally buy right now. (Steam, GOG)

Looking the source code of https://github.com/mstr-/twp-ggdump/blo ... /ggdump.py i see this

Well done.
I had to use a work-around because the size is not specified in some files probably because it's the same of the previous file... hope it works:

Thanks for the script, only works with the quickbms windows version and under windows (not in wine), the game checks for the files ThimbleweedPark.ggpack1 and ThimbleweedPark.ggpack2 anyway, and the script can't reimport files

Quote:

Error: script invalid for reimporting, it uses MEMORY_FILEs

Last script line before the error or that produced the error:
115 log NAME 0 XSIZE MEMORY_FILE2

But the unpacker/decryptor works

It' s possible to modify the script to add the reimport feature?

Yeah, script 0.1.1

Something weird happens with the reimportation, i don't get any errors but looks the reimporting is not working well (or i'm doing something wrong).

Example:
I modified a png, then i reimported without errors, but i don't see the changes, i extracted again the files and the png is the original not the modified version, but the MD5 of the .gppack1 is not the same as the original, then something changed, but what?

I see and I guess the problem is caused by the algorithm that is not one-way (so encryption != decryption), my mistake.
I restored the script removing that invalid reimporting feature.
Sorry.

Why after reimport ogg voice of characters doesn't work?

Is it possible to reimport yet? I want to bitcrush all of the voices to sound like the early talkies and reimport them.
