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

[L0v3craft]

Someone checked "Tony Hawk's Pro Skater 3 + 4" ? The pak files are encrypted. I got the key and tried with "unrealengine_R13" and after zlib/reflate and kraken too. The precompression doesn't work. I guess we need of an updated plugin?

Tony Hawk 1+2 used a custom algo.
You could always rebuild the paks like I did - but that's not lossless + CRC perfect

Any suggestion for "Le Mans Ultimate"?

Sample?

Edit: Waste of time. Use reflate on *.mas files...

Streams: 105 / 105

I am having a bit of trouble trying to compress certain Unity games. When I try to use xtool:munity,lz4hc,l12:lz4_193 specifically, it compresses just fine. When I go to test unpacking in both DiskSpanGUI and an installer (using the Setup.dll generated from DiskSpanGUI post-compression) it always fails. I do not have these issues when I use xtool:c32mb:munity,lz4hc,l12, but the former command can get a better ratio.

[KaktoR]

Try another lz4 library version, such as lz4_190 up to lz4_194.

If nothing works send a sample file where extracting fails.

All OK

You can use Zlib+Zstd and get some streams

-mzlib+zstd,l19

Compressed 2 files, 399,803,872 => 1,224,533,926 bytes. Ratio 306.28%
Compression time: cpu 0.61 sec/real 46.82 sec = 1%. Speed 8.54 mB/s
All OK

You can use Xtool Ver 0.4.3 to Ver 0.6.0 all works fine with ZSTD

Special thanks to Masquerade , Fitgirl and Kaktor

Dear ZAZA4EVER
I tried all versions of Xtool from 0.4.0 to 0.6.9 , with zstd but none of them gave me a ratio of more than 100% , I also tried with the libzstd.dll shared by you , but that didn't also work.
Kindly help me out.
Or can you share the Xtool version that you used , to compress the game with it's arc.ini file 🙏

It's all in the levels, re-read ZAZA4EVER's post and you will see that you need to lock XTool's precompressor at ZSTD level 19.

-mzstd,l19

Thanks Masquerade , it's working now
Earlier I was using -mzstd,l19 but it didn't work
Then I tried -mzlib+zstd:l19 & it worked

For Sound files use:

I'm working on "Mafia The Old Country"

I found that:
For *.pak oodle kraken core_2.9.10 lib_2 and maybe ue4 (better ratio with)
but for *.ucas seems to be encrypted => no compression ratio

here a sample

What's the method for Metal Gear Solid Delta? Tried Kraken, only got a 70.9 GB result, I think I did it wrong.

xtool:d1:mue5:mkraken:core_2.9.5+srep+lolz

[ScOOt3r]

Metal Gear Solid Delta is OODLE-Kraken
