Best Compression Methods for 'Specific' Games. Q&A

Use this to decrypt the files: https://www.fileforums.com/showthread.php?p=483980

Then, compress with xtool(zlib+reflate)+srep+lolz. You can re-encrypt your decrypted files from earlier using the same tool to get MD5 perfectiom upon installation.

I did this and the compression took a while but the results are dissapointing:

-------------------------------------------------------------------------------------------------------------------------------------------
------------------------------------------------- CONVERSION DATE 15/05/2022 -------------------------------------------------
-------------------------------------------------------------------------------------------------------------------------------------------
 11:52:56 - Deleting files from the output folder.
 11:52:56 - Files have been deleted.
-------------------------------------------------------------------------------------------------------------------------------------------
 11:52:56 - You have chosen the DVD5 type for the media size.
 11:52:56 - ISO images will not be created when conversion is complete.
 11:52:56 - The computer will remain on when the conversion is complete.
 11:52:56 - Selected ARC/DS method for Setup-1a.bin was: xtool:mzlib:mreflate+srep_new+lolz
-------------------------------------------------------------------------------------------------------------------------------------------
 11:52:58 - Compression initialized in 15/05/2022 at 11:52:58.
 11:52:58 - Starting Setup-1a.bin archive creation.
 21:19:03 - Moving Setup-1a.bin » Setup-10a.bin files to media folder.
 21:19:05 - Compression finished in 16/05/2022 at 21:19:05.
-------------------------------------------------------------------------------------------------------------------------------------------
 21:19:05 - Getting size of the game: The Walking Dead - Definitive Series
 21:19:05 - » Installation folder size: 45.49 GB
 21:19:05 - » Compressed game size: 41.54 GB (Ratio 91.32%)
-------------------------------------------------------------------------------------------------------------------------------------------
 21:19:05 - Overall input size: 45.49 GB
 21:19:05 - Overall output size: 41.54 GB (Ratio 91.32%)
 21:19:05 - Overall conversion time: 26:37:47
 21:19:05 - Overall conversion discs: 10 DVD5
-------------------------------------------------------------------------------------------------------------------------------------------
 21:31:17 - Merging Records.ini into the Setup.dll file.
 21:31:17 - The Records.ini file was merged into Setup.dll successfully!
-------------------------------------------------------------------------------------------------------------------------------------------

Did I do something wrong? I used the tool you told me and I checked MD5s before and after decryption to make sure the files are decrypted, and they were different so I assumed the decryption was successful.

To assume makes an ass out of u and me

Anyways...

Make sure you used the correct key for decrypting the data. Check in hex editor that the decrypted file starts with ZCTT. ECTT will be an encrypted archive, ZCTT means you did it correctly.

Test on a single TTARCH2, decrypt and see if you can inflate it with XTool. If you decrypted it right, you will get correct ZCTT header and XTool will be able to precompress the data.

hi guys, i want try to repack Harvest Moon: One World

from 850 Mb to 736 Mb , method pak folder srep+lolz

i see on fitgirl , she is got 196 Mb

have info ?

Seems to use Unity, try XTool or UBT?

precomp xtool doesn't work

Hello everybody! A simple question: does a more powerful PC give better compression results rather then a less powerful one?

No, only the speed is different.

Harvest Moon: Its probably use SREP and RZ (v1.00) and two LOLZ version (last and older v20d3) compressors used from final packing. And ISDone x64 v0.6.0.2!

This piggy and fbz compressor tell someone something?

fbz.exe => Blizzard v0.24b! Available from encode.su
piggy.dll -> https://github.com/kaby76/Piggy ??

Does anyone know what "cls-sndpack.dll" could be used for in some repacks? I came across it once, 3kB in size.

I need some (technical) information here.

Kaktor: Trying probable two step compressions methods, don't work?? First archive use xtool+msc only and pack again the new arc file use oggre. FreeArc anomalies, bug, not the msc/srep or any packers.

Hi all,

Been looking into Sleeping Dogs, and after a bit of discussion with some more experienced/technical tool engineers, I've got to say I'm quite intrigued. It uses a very aggressive "LZ" algorithm, with a given ".BIG" (archive format for the title in question) decompressing to over twice its original size! It also seems the WWise ".pck" files used for audio within the title have the potential for additional gains using "OGGRE"/"MSC". Unfortunately for the former I don't possess the skill-set (yet) to adapt the provided compression/decompression algorithm to be able to parse inputs for use with a chain of compressors, but none the less I think its still interesting enough for others to see.

Attached is a tool suite for processing the aforementioned ".BIG" archives, as well as a sample archive.

Came back to this one after a bit of a break and after learning about xtool's "verbose" mode, turns out LZO is used on the archives, however it seems that no matter what level depth setting or library I use no streams are able to be processed, does anyone know the reason behind this? Attached is an image supporting my findings.
