Detect the compression methods of Repackers ?

[aswadd]

Hello Guys
Basically for those who don't know how Just look at
C:\Users\youruser\AppData\Local\Temp when you are installing a repack
so If anyone want to share some methods For how to detect the compression method that some Re packers use like
R.G Catalyste & FitGirl Repack ..
I Tried [R.G Catalyse] they are using a complied bat file located in the temp Folder so i can't even know the pass of the arc files but i'm sure they are using a normal methods like precomp + Srep
For FitGirl I'm Sure she is using nanozip + Precomp but can't even know how to open her archives it always says the archive is damage run check to fix it so any one know methods pls share & we all will benefit

Hmmm... I once wanted to know myself but there are no more best compressors than PreComp,SRep,LZMA, and yeah Razor's PZLib and Reflate.
But those Repackers out there use combination of OPENING the gme files then again Packing them. That's how they achieve more compression and yeah FitGirl been using XDelta for Archive Rebuilding...

I don't know about fitgirl Work...
But I have some tool from fitgirl Installer uses for Extraction
If u find Helpful , I want to hear some Point out

I think FitGirl is using a different way for compression & Spreed maybe the main bin file for here is not even an arc one I think it's some kind of other archives that she is using to decompress the real archives so the real archives is so many & small so she can gain more speed during the installation

These files are taken from my Witcher 3 repack.
And they won't tell you much about compression probably.

But you need to know, that Witcher 3 packages uses 4 types of compression algoes in their packs. And only common one is deflate. Everything else you have to find out. Maybe temp files will help you, maybe not

Regarding my bin's. Of course I use not only LZMA in FreeArc, but other compressors too. All public, though. I brute-force different types of data to find the best method. I keep all recordings of back-log archives, so when I see similar data, I already know what to use.

I use multicore decompression/compression, when it's possible and gives speed benefit (like Mad Max, where deflate compression is on minimal, 1 level).

Nothing special, leading Russian groups like RG Mechanics or RG Revenants do the same. Also groups (especially Revenants) have special tools and CLSs for compression/decompression Unreal packages or BINK videos. And of course they aren't public.

As opposed to your ideas, here we are in a public forum, where it is nice to provide their knowledge to those who thirst for learning, logically nothing obligatory.
This way you respond with the conviction that hardly anyone can understand the structure of compression and decompression of your work, do not think that benefits the guys here on the forum, in fact I think not really lead anywhere.

If I would be in boots of the person who asked, I would already understood, what files inside attached archive are doing. It's human-readable batches, for God sake.

Please don't expect from me real-life examples or compression strings for certain types of data. I'm not a teacher. If that's against the rules, I won't type anything else here, no prob.

Hey fitgirl how i can made .map and .sml file. Also tell as everything

My friend made it for me, it's universal, and, sorry, exclusive to my repacks. But the idea behind this tool is very old and was used many years ago by different scene groups like CLASS. So if anyone has knowledge and time, he can write something similar in a day or two.

*Sigh* Again this thing is up huh...Man, quit copying her methods, I'm just tired of yelling it, like JC3 too, you can achieve same compression w/o burning HDDs yet if you guys are so fixated upon copying then go ahead...Just change the name of this section into "Copying Tutorials"...

.map and .sml file are probably data1.tmp and data2.tmp of Reflate.Even the name suggests that .map contains sizes of streams..

May be , All coders will find out ur Work very soon Meantime we r happy with our Work
B'coz this forum is for learning & doing Stuffs
I was just helping this person who started this thread If he was able to find ur work
If u don't want to share ur work , No problemo FitGirl

Uh, no. You know, there is a thing called "Hex Viewer". Google it. Then use it on some samples. Maybe you'll learn something new.

For questions to be answered, they have to be properly asked. Not "WHAT METHODS ARE USED". It leads nowhere.

Are u really fitgirl...
B'coz ur join date is 2014..it means u were visiting this forum till now...But no post any comment...Ohh Jesus
