Extreme Black Box compression - how ?
 

Welcome my friends!

Currently working on a repack of Far Cry 4.
I noticed that the Black Box released his repack of this game, which is 12.4GB. My question is: how the hell is it possible?

The game normally takes about 25GB after removing unnecessary language (other than English). I spend almost a third day on this game and I was able to pack it to the size of about 18GB. Game files are not susceptible to PRECOMP, so I use compression SREP + lzma.

Can someone explain to me how they were able to get such a small size?

Look in "C:\Users\%USERNAME%\AppData\Local\Temp\" localize temporary files of setup to know their methode.
If you want to remove English, to keep only French example, you will have to rename like this: fcc_main_french.dat to fcc_main_english.dat after having everything rename, simply add the registry key corresponding for your language:
Root: HKC U; SubKey: Softw are \ Ubi soft \ FarCr y4 \ 420; ValueType: string; ValueName: Langu age; ValueData: fr-FR; Flags: uninsdeletevalue uninsdeletekeyifempty

Sorry for my bad English :cool:

I removed already foregin languages and kept only english files. And know also about registry keys.

I Have installed parallel version RELOADED (I repack based on this version) and the BlackBox. I removed unnecessary files and they take exactly the same size as the version of BB, and yet repack BB is much better compressed.

During the installation of BB repack, can't see anything interesting in the temporary folder (see attachment file). By default, SREP PRECOMP and Unarc files.

So what does this mean? That their repack was compressed using PRECOMP and SREP? But I checked each file using PRECOMP and none were susceptible to its effects (.pcf file had the same size, hasn't increased).

I'm convinced that the devil is in the compression commands, but I don't know them :(

Any ideas? Anyone?

I do not have the setup version, but what I see, I can tell that it uses precomp 0.38 packjpg, after you have properly selected the files for precomp.

Black Box Repack is prohibited in this forum :rolleyes:

Sorry...

Ok, let it be banned. Just trying to understand the compression method used in the repack and I don't see anything wrong with that ....

So let's focus on the problem ...

There are many newbies who read the post, unload the box in question take the risk of a virus just to figure out the compression method, for this you can understand that it is not good to give examples with black box repack that you already downloaded to your pC reading the screen ... just saying. you can have a repack of Far Cry 4 18GB, I would say (it even much less) do it this way.

_EZEKiEL_ No problem you just responded to a comment my friend

Forget about problem dude. :)

Heck no! :(

I don't want to forget, but to understand this method of compression.
Please don't spam meaningless posts - concrete answers related to the first post ....

Try this method:

Nope, the output file is even slightly larger than using the standard commands: I ran a little test and I noticed two things.

In the attached screenshots on the left side is my sample file, and on the right side original file from BB repack (I omit the issue of the size of the input file - this is just a sample).

In the first screenshot, in my case, we can see significantly lower average of blocksize 122MB compared to BB 12GB file. How can I increase the size of blocksize ??

In the second screenshot you can see that I used the same method of compression, but in the case of BB you see two types of compression: Storing (posit. Size 0, compress. 0 ???) and then use the method of SREP + lzma. Someone can explain it to me ??

bsize -s12gb

why the hell do so much confusion that does not help, you have opted for options like: audio resampling, resampled video, languages, and so on.
do you think these guys are geniuses (you are wrong) maybe read many tutorials on the functions and methods of conversion or maybe they have their own deck, perhaps playing yugioh ;)

[solved]
 

Thank you for this switch - will check it tomorrow.

I did it! Finally, after many attempts I managed to compress this game to repack the BB size, and more! My folder was about 1GB bigger (25.8GB), and I managed to compress it to 12.9GB - 0.2GB less than BB repack! Yeyyyy! :)

It seems that compression using SREP is more effective when we use it on a SINGLE LARGE file, rather than smaller packets of data. So first compress the entire folder with the game using 7z or arc (can't remember), without the compression level and then I treated this large single file with the SREP. It gave me the final file size 12.9GB.

The riddle was, at least partially, solved;)

And now there is another problem, but with this I invite you to THIS topic ;)

Try this methode:
arc a -lc8 -ep1 -ed -r -w.\ "Data.bin" -msrep+lzma:a1:mfbt4:d158m:fb273:mc1000:lc8 "G:\Far Cry 4 - Gold Edition"


25GB ==> 12,8GB

wow :)

this is mine

I Converted whole far cry 4 v1.6 data_win32 folder using this option
arc a -lc8 -ep1 -ed -r -w.\ Data\Setup-1.bin -msrep+lzma:a1:mfbt4:d256m:fb128:mc1000:lc8 "D:\Far Cry 4\cd1\*"

Ratio was 51.0%
From 25.8 GB to 13.2 Gb...

Far Cry 4 repacked to 6.7 GB, that's insane compression

Why not share the methods? It's what this forum is meant for? ^_^

Corepack for Far Cry 4 is used rebuild archives. Then it has a smaller size of compressed but again increased in size after unpacking. :confused: :confused: :confused:

^40% true, that didn't help actually. Rebuilding the game archives made the size possible to 11 GB only, done by KacTus Repack Team

could you show how to use this switch?
many thanks

i have add the s12gb in the arc.ini but didnt work for me?

try with -s12g instead -s12gb
and if you have a lot of ram try more dic size d1024m or d4096m
and cores -mt8

And what the command line for unpacking this?

You Coregames are a buch of something which do not belong here. Yeah you may ban me moderators but one of the member of this guy came to me and wanted to join, bt I said that i can't run so I told em to talk with razor12911 and now you are famous by repacking farcry 4.</br>
One thing I want to say is, create conversion for original game as some people like me has limited download speed.

No command line. But this dont really belongs here. :)

arc x -y Data.bin "G:\Far Cry 4 - Gold Edition"

And can you please tell me the guy name who came to you ? Cause I am the only one who repack games in the team and never did I met you in the past. Though I know Razor12911, he's my friend and very good in making installer. He's the guy who helped out in making our installer.

Last thing, Far Cry 4 is not the only repack for which we are famous.

Corepack repack far cry: Without dlcs, one language and use srep64 and precomp043

No patches files, no hd textures, no music files...

which is the best script compression?

MSC+PRECOMP+SREP+LZMA 64bits and precomp 042 not found?

precomp only adds a ton of time to compression / uncomression NOT worth the extra time.

who wants to take 3-4 hours to install game compressed with precomp ? because it takes just as much time to uncompress as it did to compress it with precomp.

I want Archive.ini with three disk's Setup-1.bin,Setup-2.bin,Setup-3.bin

25.9 GB ==> 13.3 GB

BlackBox use RAD Studio XE7 for creating their new installer:D

I serve this data with FreeArc info of this game

m3f?????

as I can create a compress.bat

Compression parameters for srep. Also you can use 1gb of dictionary. m3f:d1g

and how I can do that?
