6 years ago @felipedmc, are you sure this isn't just an Inno Setup archive with / without third-party compression?
Supporting such a thing might be within scope (@Bioruebe ?), but what you're describing seems likely to be encrypted using Inno Setup's own DRM or some third-party DRM scheme to prevent someone like you from re-releasing "FitGirl-brand" installers with malware packed in, or just to prevent you from taking credit for the work.
Evading Inno Setup's default DRM probably isn't hard (although it's illegal or questionably legal at best in some countries—including the United States), and I'd be unsurprised to find extant code elsewhere to do it... but trying to account for unknown third-party DRM seems out of scope to me.
Unless you really think FitGirl archives or similar archives really are packing in malware, you're probably best off just running the installer. I haven't experimented with UltraARC, but, from the look of it, you're probably wasting time and a lot of electricity trying to better the compression. If you just want the files, the only downside of the installer is—I assume—an uninstaller entry you'll just have to remember to remove (or run?) when you're done with the files.
From a look at the FitGirl file manifests out there, the installer .EXE itself is at least small enough to upload to VirusTotal, if that's your concern. Taking into account unknown code inside the archives themselves: any reputable antimalware product you can buy or download for free should be able to detect and extract an Inno Setup archive that isn't wrapped in DRM or other surprises. I've watched Windows Defender unpack and analyze quite large Inno Setup archives, including the ones I've created, and I'd be quite startled to hear that Avast! or COMODO or the like can't do the same.

6 years ago Follow-on thought: I would not mind seeing basic support for Inno Setup archives packed with UltraARC; it could be useful for some of my research. If I find the time, I may experiment with the tools posted in the thread I linked to see if they alone are enough to do the job.

5 years ago "Q: How do you compress games? With what tools? A: I use mostly FreeArc for compression and Inno Setup as an installer. Some games require other compressors, but in 99.9% of cases it’s FreeArc."
fitgirl has spoken. InnoSetup+UltraArc using Freearc compression.
There is no encryption. it is only used when a password is required for setup, to force people to actually need the password. So there's no "InnoSetup DRM" to worry about.
the bin is a split file format, with the compressed files stored in it. i'm going to try and throw freearc at one of them.
okay the setup contains the tools to decompress the bin files. it is nearly always freearc with srep, and an ARC.INI telling it how to do it. you can unpack the setup with innounp.exe, which will get you the installscript and all the files needed to unpack the bin files.
https://encode.ru/threads/43-FreeArc/page81 info might be useful here.
You should be able to bypass the setup.exe and extract the bin files directly with a copy of unarc.exe, srep.exe, and an arc.ini configuring SREP.EXE as an external compressor. you can extract the ini and srep.exe from her installer. Note that this will bring your computer to it's knees just like the installer does, as srep is a ridonkulously huge dictionary compressor, capable of using dictionaries larger than your RAM (!).

5 years ago The setups are clean. the ability to reboot the OS is a common feature to have in setups, the url is to her site, the suspicious api is ultrarc. They are bog standard innosetups with ultraarc's freearc module and dll and srep. Extraction with the innosetup extractor backs this up.

5 years ago recently they switched to another compression algo called Lolly, do you know how to extract it?
The-SamminAter
commented
4 years ago @eadmaster the compression algorithm switch was made back in 2017 I believe (looking at the timestamp), and it was mentioned here, that the (lolly) compression algorithm isn't public.
I don't know if this is useful or not, but while setups are running, a folder with the extractors is created in the Temp directory. This gets deleted when the application is closed, but you can duplicate the folder to get the extractors.
I suggest checking that out, as it may be a simple, out-of-the-box way to decompress FitGirl Repacks, though I doubt that it'll work.

4 years ago @rmenessec I'm newbee at this point so I can't say if there are any illegal involved in this situation, but as @zaphod77 says (from what I understood), it seems to not use free tools and no encryption.
@zaphod77 The point is that I still not know if their repacks are safe or not, as you suggested the ultrarc maybe suspicious.
Even reading the responses I still do not understand if it is possible or not to make UniExtract support thoser repacks.
More explanation?

4 years ago Hi, I finally found a way to extract repacks. Today I'm going to show a way to extract repacked game without installing them.
PREREQUISITES:
This method will work with some of the simple repacks but we are using Watch Dogs DODI repack for example.
STEPS:
I. Obtaining the Specialized decompressors that repacks use.
cd /d D:\innounp049innounp -x -m setup.exe -doutputII. Integrating them in FreeArc.
III. Extracting the Repack.
HURRAY!! YOU HAVE SUCCESFULLY EXTRACTED THE REPACKS.

4 years ago @pratikpatel8982 I made an account just for this.. You've done a fantastic job up until the slight vagueness of the final steps(IMO).
I assume when you say navigate to setup files you mean the fitgirl repacked game bin files? and if so, freearc's error at the bottom says it isnt an archive or corrupt ( I've verified the files several times with tixati and quicksfc) and i'm guessing this is because it isn't an .arc archive.
Could you help me understand what i'm doing wrong? Google says you're the only one posting instructions on unpacking fitgirls games. If it helps i'm trying to uncompress DCS world (250gb uncompressed) as I only ever have issues with her very large games and cant get this one installed.
Your guidance is appreciated :D

4 years ago The custom tools used to extract the files are present in her repacks, would it be possible to figure out how they work or how to use them?
Thinking it might be helpful, a while ago I tried running every executable in the temp folder created during the installation of a repack, here's what I found:

3 years ago keru1264 has a bit of a point. Knowing which packages are trustworthy is up to you when it comes to pirated anything. In my opinion this is a basic knowledge when it comes to pirating. Nearly all pirated programs will register a false positive and are usually safe.
We all learned one way or another and trial and error is a bitch. I'd suggest a virtual machine for programs you're unsure of as it will "trap" malware. Or just an old POS lol :p
Any one of the geniuses here figure out fitgirls recipe yet?

3 years ago anyways i figured out why I got the trojan. The setup file from the repack was modified and infected by attackers. I went to fitgirl's official website and got the setup file from there. It was different and and worked and installed the repack safely without defender detecting any trojan. Beware and only get the repacks from official site. Don't download them from anywhere else as you'll lose your privacy once that malware is in your os.

Hi, sorry for delay. I tested this method on several repacks, but it only worked in some of them. I posted the same tutorial on some other forum and fitgirl herself said that it may not work on complex repacks which involve rebuilding of game data. It will only work on simple repacks.

3 years ago Hi, I finally found a way to extract repacks. Today I'm going to show a way to extract repacked game without installing them.
PREREQUISITES:
This method will work with some of the simple repacks but we are using Watch Dogs DODI repack for example.
STEPS:
I. Obtaining the Specialized decompressors that repacks use.
- Extract innounp somewhere in your computer.
- Obtain the setup file of your repack.
- Copy the setup file to the directory where innounp is located and rename it to "setup.exe" without the quotes.
- Open Command Prompt as Admin.
- cd to the location where innounp is located. (here it is D:\innounp049)
cd /d D:\innounp049- Type the following command:
innounp -x -m setup.exe -doutput- The setup files are extracted in the "output" folder
II. Integrating them in FreeArc.
- Extract FreeArc Somewhere.
- Navigate to the output folder and open {tmp} folder.
- Copy all the files from this folder (except the .png and jpg files) and paste them into FreeArc\bin folder and overwrite if asked.
III. Extracting the Repack.
- Open FreeArc.exe as administrator. [IMPORTANT]
- Navigate to the setup files and extract them one by one.
HURRAY!! YOU HAVE SUCCESFULLY EXTRACTED THE REPACKS.
Thank you for your instructions. But strangely some bin do open and extract, but most of them are not. Can you tell me how can i extract those too?

That's why I said that It'll work on simple Repacks.

If it Extracts with the above method, it's simple. Else it is not

With the information from these (and other sources), along with the tools contained in (presumably) all of FitGirl's repacks, one could likely extract the data from any of their repacks, including non-'simple' ones.

3 years ago Some things I found:
- List of lolz cli arguments
- Repack script for one of FitGirl's repacks
- FitGirl explaining their repacking and unpacking process
With the information from these (and other sources), along with the tools contained in (presumably) all of FitGirl's repacks, one could likely extract the data from any of their repacks, including non-'simple' ones.
I'm going decode this for you.
How repackers compress their game? Repackers use (fitgirl and other repackers) freearc to compress their games. FreeArc has three main files:
arc.exe: used for compression
unarc.dll: used for decompression
arc.ini: It is used to integrate more compressors to FreeArc, like lolz, srep, XTOOL, etc.
How does this archives are unpacked Most of the repackers don't use vanilla freearc to compress their games. They use a custom version of arc.exe to compress their games and use its corresponding unarc.dll along with arc.ini to decompress them. This custom arc.ini make archive differently so that It'll give error when trying to open without setup. Usually pos discriptor at block (insert a random number here) is corrupt. They also put password to their archives to protect them.
They create a setup file along with the decompress it's that decompress the game. Now with the things you found:
Now I've found another way to extract simple repacks with the encryption I mentioned above. Basically you extract the setup, and obtain the files inside it and use another script like (2) and edit the script. You need to edit:
The name if file you want to extract.
The compressors that you obtained from the original setup.
Then you can compile the script and place the output file near the archive and try running it to see if it extracts the file or not. Also not every script will support the pos discriptor archives.
Trust me, I've done Repacks for the past month and unarc.dll is the main file here.
What you need to understand about Installer scripts:

3 years ago So based on last comments I believe it is possible to automate it, right?
But it keeps me curious... why all that protection barriers for compress something that is not suppose to be harmful? I mean, what is the point doing that...

Because of competition. The Repacks use compression algorithms (commands used to compress the game). Repackers protect their archives to protect their compression algorithms from being stolen. There is always competition between repackers with regards to repack size, and hence they use these methods to protect their algorithms.
The method I posted May be able to extract the archives, but you'll never know what algorithms were used to compress that archive.

3 years ago Another workaround for this would be some sort of Windows exe hack where it forces the setups to install into a fake location without really rendering the GUI and then just grabbing the extracted files that were "installed". Users of Chocolatey might have some idea on what I am talking about. While the compression algorithms vary, the repack setups do not.

FreeArc has been abandonware for some time now. the best way to download it would be through the internet archive. https://en.wikipedia.org/wiki/FreeArc https://web.archive.org/web/20161118235221/http://freearc.org/download/0.666/FreeArc-0.666-win32.exe

1 year ago does anyone know the arguments for unarc.dll?
so far i have
typedef int(__stdcall *f_unarc)(int,int,int,int);
HINSTANCE h = LoadLibrary("unarc.dll");
f_unarc unarc = (f_unarc)GetProcAddress(h, "FreeArcExtract");
unarc(?,?,?,?);

- I recommend (I personally use this) using this script. It supports archives with pos discriptor error provided that they do not have a password.
Unfortunately this link is (currently) dead. Your help has been very valuable, and I feel so close to being able to extract the bin file I have from fitgirl, I'm getting the correct arc.ini data when I do arc.exe --print-config, but I'm still getting block descriptor at pos errors.

1 year ago Hey guys nothing comes out about extracting fitgirl bins its really annoying the installer takes all my laptop's rams just for a small game
FitGirl is one of the most well known encoder and uses very different algorithms for each game she repacks. UniExtract being able to handle her compression, setups, compiled .bin, etc certainly will take UniExtract to another level.
FitGirl site - http://fitgirl-repacks.site/
Note: Everybody says that she uploads clean files BUT I'm not sure... so try to use some sandboxed/isolated environment. (https://www.hybrid-analysis.com/sample/a485678f9d9e4c6614bda8398ae1d8c7832478d645ff77da2474b51c97306100/5ab591297ca3e157e51ea163)
I know almost nothing of code but I can test things for you, just e-mail me ok!
