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

But I think this was invented for cases if you need two libraries for the same files.

In your case you need two libraries for different files.

I don't think this is possible.

Try it with "--oodle=" option.

Example

[External compressor:xtool7]
header = 0
packcmd   = xtool.exe precomp -mkraken -t100p --oodle=oo2core_7_win64.dll - - <stdin> <stdout>
unpackcmd = xtool.exe decode -t75p -s - - <stdin> <stdout>

[External compressor:xtool9]
header = 0
packcmd   = xtool.exe precomp -mkraken -t100p --oodle=oo2core_9_win64.dll - - <stdin> <stdout>
unpackcmd = xtool.exe decode -t75p -s - - <stdin> <stdout>

-mxtool7+xtool9

Edit: Try this without xtool

It doesn't work.
I've more or less decided that. But the fact that chapters 1 and 2 have different AES is something I do not know how to solve.

ch1 - 0xD4BCF215F3B33A4BAA8D52139F1F49E92DF5BF8C7262C823E846AA6D79331FBC
ch 2 - 0xA419DEC1C6949BE5BDA54D4D6A62D735E932640B5F03EB53A3E72B10BAEB9748

have you tried doing -mxtool7:<aes_for_ch1>+xtool7:<aes_for_ch2> ? you have to change your arc.ini to take aes key as option.

No, but it work fine with ue4d by Shegorat.

ue4d:game=510:game=511

[Masquerade]

For poppy, I ran ue4d followed by 2 instances of xtool with the --oodle option.

[KaktoR]

There is also a tool for resampling audio files to get higher sample rates.

PS: I guess "re4lfs" does the same as cls-red4 does.

[KaktoR]

Welp.

Then you have to compress them separately.

Somebody found a way to process 2023 unreal ucas/utoc version of Gotham Knights?
Because I can use xtool with unreal plugin and AES key E01312D26CAD1529142D3ACA6DB25D4091C1AAFE0C91E5DC10 4C36A768DB1E50 on .pak file without any problem (.pak is only file in old 2022 version of game, and smaller file in 2023 version with ucas/utoc) but *decryption* in not working in any combination of parameters on ucas.
FModel unpack file with mentioned key correctly so in theory it is possible. Compression it mention is LZ4(strange, usually it is oodle), but I cannot get to that part...decryption is the problem. In short, maybe there is a way to decrypt ucas/utoc with xtool+unreal plugin, or plugin for it or bms script that works...or maybe I missing something obvious. Thanks, regards

Use d1 parameter

Of course d1 is used. This is not my first Unreal AES game that I archived. It did not help. Since it is Unreal 4.27 game, tried cls-ued4.dll also (I prefer it actually since it is usually faster at decompression than xtool with plugin), but this also did not help. Old version worked since it had ~32GB .pak file and nothing else. Current version is upgraded to IOStore container, there is .pak but it is ~12GB and .ucas is 32GB. Smaller .pak will decrypt fine (with -d1 of course) but .ucas is, as it seems, custom...

[KaktoR]

I would bet the PAK file contains all the audio.

Can you send a small cut sample (200mb) from the ucas file? Also send utoc file.

[infovs]

Included cuts from pak and ucas, utoc is complete.
https://gofile.io/d/Hozz2N
As I said, pak can be decrypted and inflated with mentioned AES key, but can' decrypt ucas, even tried with ue5 parameter for unreal plugin (even if it is ue4 game) but still no luck, looking at created arc nothing is decrypted.

[KaktoR]

It's an older utoc v3 format.

However I couldn't decrypt it either. I created a xtl file with ue5 db maker, records are shown but nope.

Maybe someone else can help you.

PS: I hate ue5 engine.

[infovs]

Thank you for your time KaktoR, it seems the developers have gone extra lengths to implement custom scheme to ensure that no one can mod the game easily..

It'd probably be easier to unpack + repak the game data.

JP audio ripped.
Movie files are encrypted for some reason so just use something fast on them. No need to waste time.
