Thank you in advance,
cordially

It's built in unreal engine, so for the Pak file use xtool with zlib codec+srep+lolz then for everything else use srep+lolz.

So:

*.pak =

xtool:e:precomp:zlib+srep:m3f:l512+lolz:dt:dtb1:dtw1:dtm1:dto1:dtd1:mtt1:mt4:d64m:fba4096

Everything else:

srep:m3f:l512+lolz:dt:dtb1:dtw1:dtm1:dto1:dtd1:mtt1:mt4:d64m:fba4096

Enjoy the conversion!

Hello there, I am currently looking to compress the game "Astroneer". I just wish to see how small I can compress the game.

It is an Unreal Engine game, so I used Masquerade's guidance from the last page for Drug Dealer Simulator however I am wondering if there's any better compression method for mp4 video files? It seems that srep+lolz do not compress these files very well.

This forum has helped me a lot since my first post. Thank you in advance.

The Amazing Spider Man 2 (2014) has a file called Streams2.dat, it's the largest file in the entire game (2,323,030,372 bytes / 2.16GB) and I don't know how to compress it efficiently.

I threw it into RAZOR12911's scanner and this was the result:



There's zlib streams so I decided to use XTool Zlib, but that didn't do anything:

Compressing 2 files, 2,323,030,372 bytes
  Compressing Data\
  Compressing Data\Streams2.dat
Compressed 2 files, 2,323,030,372 => 2,323,031,492 bytes. Ratio 100.00%
Compression time: cpu 2.23 sec/real 72.99 sec = 3%. Speed 31.83 mB/s
All OK

ZTool zlib was the same:

Compressing 2 files, 2,323,030,372 bytes
  Compressing Data\
  Compressing Data\Streams2.dat
Compressed 2 files, 2,323,030,372 => 2,323,035,496 bytes. Ratio 100.00%
Compression time: cpu 2.09 sec/real 50.60 sec = 4%. Speed 45.91 mB/s
All OK

PZLib also had a simlar result at a 100% ratio.

Is there something I'm missing here? There's also lots of WAV streams detected, but I don't know how to focus on them. I tried MSC, but that only found WAV streams of an unknown file type, and did nothing.

I don't think the file could be encrypted because the streams were detected.

If anyone has any tips, they'd be greatly appreciated.

XTool + MSC?

I tried adding the c128 command into XTool and it slowed it right down, taking ages to go barely 0.1%.

[devil777]

@Masaqurde... use "srep+lolz" method it'll worth the time I hope...

Also have you tried the x86 version?

It's defintely not Unity, there's no Unity binaries or File Structure present for it to be unity.
