Detect the compression methods of Repackers ?
 

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...:rolleyes:
But I have some tool from fitgirl Installer uses for Extraction;)
If u find Helpful , I want to hear some Point out :D

I think FitGirl is using a different way for compression & Spreed maybe the main bin file for here is not even an arc one :D 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

yee i'll try it :D of course :o

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..

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

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 :cool:

:D For God's sake :D, you can write what you want here on the forum, and we do not expect any type of teaching from you, do not we need, but it would be nice to read from you, some interesting answers.:cool:

I can answer, but as I told above, the questions should be normal. You know what they say? Correct question contains half the answer. And that's true :)

In fact SAM ;) "join dates 2014" I see them as someone who has always taken and learned from our work, and has drawn personal benefits, and they never gave.
for me you have got off on the wrong foot.

:rolleyes: OK...FitGirl ;)

thanks for the asnwer. I'll try.

The only thing I learned from this forums is RAZORs pZlib.
Everything else I learned myself, cause Google is a girl's best friend. And I'm almost 2 years in compression, c'mon.

Fileforums is more about installers, than compression itself. And I don't use pre-built tools like Compressor anyway, because they are GUIs, whereas I prefer simple CLI where I control every step.

My God, fitgirl :eek:

You are the best!

Maybe a tool called "Wave Injector" used by a oldschool warez group CLASS/BLACKLASH can do the same re-injection of files, like the old method:
Search/extract files using Dragon Unpacker (Wav or DDS), and inject an copy of dummy files into the main file. I know the tool thanks to Skullptura Games

Sorry for my bad english and thanks FitGirl for the amazing work :)!

Yep. But in my case it's no dummy space inside, but zero-space. Better for repacking.

KapitalSin also used in cleaning and injection file ...

In my opinion the best repacks, NOTHING ripped, NOTHING re-encoded, are FITGIRL REPACKS, and the best rips and re-encodeds are KAPITAL SIN, (almost always multilanguage)....

Sorry for my english..

KaosKrew are also good for rips. Some other groups steal lossy repacks from them :)

kaos appropriated profits created by kapitalsin and used their repacks

THNX FITGIRL :) Also The only thing i got is that .. Splitting the game in different file types then trying over 40 method to get the best method for specific type you are testing on :D & Yes i have much Ram (80GB) & CPU on my RDP to test rapidly :D

Just one qus ? are u from china or not ?? because china has a massive information about Programming so it's normal to see someone from china who do like you :D

One last thing i'll try to catch your method i'll try to restore the recently deleted files From the Drivers then i'll try the reverse engineering or i'll ask some of my friends who are expert in reverse engineering :p:p

I'm from Russia, but live in Latvia for many years now.

For better challenge, ask your friend to revers-engeneer Revenant's BINK-decoder. My files rebuilder is so simple thing, it's faster to program it from the ground.

What`s with the Revenants BINK decoder, send me a link to the installation that uses it, and I could try to get you files that you want.

if I had 80gb ram i used ramdisk.
research it if you don't have ssd.writing-reading speed is important.
fitgirl's method is good but we don't have a tool like this.these tools are looking hex codes of this files.Can dragon unpacker edit or delete this files-datas?it can find with hyperripper but what else?

As far as i know Dragon Unpacker can only unpack files, tough i didnt used it in years lol, something might have changed :D

I remember one repack with that, F1 don't-remember-the-year. But actually any Revenants repack of the game with BINK videos will use that compressor.

But as far as I know it's impossible to restore the algo, only decoder is available. And CLS-encoder never left the group.

Actually, MSC is also Revenants product, and DLZ (extended better-than-LZMA-encoder, available for Revenants only).

So those guys are real pros. It's sad they repack so little games novadays.

One of their latest repacks, rvn-mkke (Mortal Kombat: Komplete Edition [RePack v1.2.1] 5 GB) uses all 3 custom tools - DLZ, BINK and UE-rebuilder. But I don't think that anyone will have some luck :)

it's a Hyper-v RDP 80 GB Ram :) So I use it to quick compress the same file in many different methods then i'll use the best one for the file :D It's easy if you have A Huge RDP SERVER

your MGS V have 2 precomp files O.o why you are using 2 precomp :D what is the benefit of using 2 versions of precomp :confused:http://i.imgur.com/KPXmKzU.png

& why the 2 precomp have a different size from the original one O.o & what about run.exe it's confusing me a lot as Malwarbyte always deletes it
