i found the compression algorithm in the game code

Oh, can you share with us?

You can start here

A Plague Tale: Innocence uses LZ4.

Thanks. I'll update wiki article then.

It was LZ with custom flags.

That's awesome. I will definitely check this.

So I have been working for few days on Asobo games formats. First I have created a tool and documentation on my github https://github.com/bartlomiejduda/Tools/tree/master/NEW%20Tools/Asobo%20Studio%20DPC%20DPS%20Research Then I have copied all informations to Xentax wiki https://wiki.xentax.com/inde...

What game is it from?

Looks like standard texture2d file from Unreal Engine with some compression.
Did you use gildor's tools?

Here you have Wiki page with lots of articles and tutorials https://nsis.sourceforge.io/Main_Page

Today I have found a very interesting lists on Wikipedia. These are lists of commercial video games with released source code (also leaked source code). :D https://en.wikipedia.org/wiki/List_of_commercial_video_games_with_available_source_code https://en.wikipedia.org/wiki/List_of_commercial_video_g...

In the header you have string "NullsoftInst" which indicates
it was compilled by NSIS.

You can get tool's source here https://sourceforge.net/p/nsis/code/HEAD/tree/
and figure out the way it saves executables.

otherwise the game won't boot? To be honest, I'm not sure. I suppose it depends on the game :) I can imagine situation when game have custom CRC checking procedure etc.etc. I can also imagine some custom packing procedure like this: def store_unknown(res_offset, res_type): unk_val = make_hash(res_o...

Great work with researching this file format.
I'm just guessing here, but maybe this unkown is CRC value or hash value?

Thanks, it works now.

if the original archive uses complex encryptions that require the usage of MEMORY_FILEs to perform temporary decryption, then it's NOT supported and the same is valid for chunked content (like those scripts that use the command Append) From version 0.6.6, QuickBMS has an experimental mode for reimp...

Access is denied to your document. You need to make file public.

Yeah, in most cases it can be used for reimport.
Everything is explained in documentation https://aluigi.altervista.org/papers/quickbms.txt

First you need to find the palette

In TC 2.0 I would suggest to look in .rrgb files first,
but in TC 1.0 I have no idea where it could be stored.
