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

I wouldn't say it is undocumented. The problem is that the game in question is exclusively for the oculus rift vr thing. Libraries can differ on different platforms.

And if I look at all the code in shared library, it differs much from the pc equivalent.

Cyberpunk 2077

I did a bit of digging in last few days. Here are some observations. Maybe you might find it usefull.

Code:

audio*.archive

lang_*.archive

Contains WEM's, BNK's and BIN's.
For the majority of WEM's and BIN's you can use WEMTool from Masquerade (rename *.bin to *.wem first).
For some of the files you have to use MSC, look out for this. Honestly I did not have checked how much files are affected by this, and I don't even know if there are tools out there which can check for specific blocks or decoded text to separate the files to be used by WEMTool or MSC.

Code:

basegame_5_video.archive

ep1_2_gamedata.archive

These two files contains bink2 files, for which you can use the xtool bink plugin. However the file "ep1_2_gamedata.archive" also contains other files alongside with bink2's, so I guess it should be wise to process the file together with all the other archive files if you don't want to extract the file entirely. However the binks are stored as plain text, so you can patch them out of the file and compress the extracted binks together with the "basegame_5_video.archive" file. Patch them back afterwards (not tested). Bink2 files have *.bin extension.

---

You can unpack the archives with WolvenKit.
I used the console version and used command like this

Code:

WolvenKit.CLI.exe <command> <InputFile> <option><OutputFolder>



WolvenKit.CLI.exe extract "G:\SteamLibrary\steamapps\common\Cyberpunk 2077\archive\pc\content\audio_1_general.archive" -o"E:\Test\audio_1_general"

Use VGMStream to check audio info.

Try QuickBMS if possible?

Tony Hawk uses a non-standard encryption scheme such that decryption is possible using the attached script, but encryption is not.

How could I use this in DiskSpan_GUI?

FAZip gets stuck while compressing Forza Horizon 5 files excluding zip files.

even after 7 hours FAZip uses high CPU and RAM but there is no disk activity.

compressing using DiskSpan_GUI v2.0.1.9 (x64)

method: rep+srep+LZMA-MT (stuck at 100% error level) or srep+LZMA-MT (stuck at 33.5% error level)

conf: i5-13600K + 32 GB DDR5 5600MHz RAM + 2 TB NVMe SSD

Most likely it is because of lzma. On some inputs lzma has insanely times to compress data. Try with another method, like fast lolz.

Oh, and do not compress games on your SSD, because of all that data write you will let your SSD die sooner then later.
