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

[mr_gnar]

Kingdom Hearts HD 1.5 + 2.5 ReMIX
Main files - Xtool(xzlib)+srep+lzma (lolz takes 3 hours longer and there is barely a difference)
Video files - srep+lzma

Starting size: 45.84 GB
Output size: 34.4 GB

- Days/Recoded videos are ripped, since they're just compiled cutscenes turned into two extra movies.

Has anyone looked at the video files yet for the main games? They seem to be MP4s, but it's not possible to view their metadata/bitrate or even play them. I assume there would be no way to remove this encryption, right? Never heard of videos in a game having such a thing before.

Method : xZLib+SREP+LOLZ
Method 2 : SREP+LZMA
Method 3 : SREP+4X4:LZMA
Initial Size : 33.6 GB
Final Size : 26.6 GB
Hints : *.pak - *.usm,*.uasset,*.awb - Other Files

I was trying to decompress DBZ : Kakarot with the methods mentioned above. I was able to extract all the archives except the *.pak ones, which were compressed using xZLib+SREP+LOLZ.

While decompressing, i ran into an error saying :

ISDone.dll
Error code : -12
failed CRC check at pakchunk0-WindowsNoEditor.pak

If someone else faced this issue before or it was discussed in the past please refer me to that thread.

Edit : I managed to decompress the *.pak archive with LIS.

It might be the code itself?

The installer code? maybe, i am going to try some other installer scripts and see if it works.

For this one i used WPI by Razor12911 - added some external compressors and most of the time decompression goes smooth.

Edit : Check above messages.

They are mp4 files for sure. Looked a bit with hex

But seems to crypted or somewhat, for whatever reason.

Was there ever an LZMA precompressor? I was reading some ancient threads in my search. At the time, it was said to be a difficult task and to avoid large xdeltas the right params had to be used in recompression. Read a bit on Encode through the wayback machine, but nothing really related to what I was looking for.

Reason I am asking, Crash Bandicoot N Sane Trilogy uses LZMA compression on the archives:



There's an Extract tool for this game which removes the compression from the pak, and saves it as an decompressed pak file, only thing is no way to re-compress said pak.

https://github.com/AdventureT/Nst-Ex...r/SevenZip/sdk

Update: https://github.com/pashok6798/Crash-.../master/CBNSTT

I found another tool with compression abilities, however it is a GUI with no command line unfortunately. Its says it can compress but it doesn't appear to do.

Tell me, What about method compression for CoD Infinite Warfare? get-vidmateapp.com get-mobdroapk.com

Hex Edit instructions for LEGO Star Wars: The Force Awakens, to make the game run unpacked.




Taken from Zehax, however the game version this change works on isn't specified.

Anyone can test this?

I'm still searching for how to patch these games, but everyone I've talked to is hiding information and doesn't want to share how to do it.

Hello!

My questions: How to repackaging very old MSTS game with highly compression ratio?

Its probably make likely, two different variants for:

1. Very old PCs (1-2 Core CPUs) users with XP x86 SP2/3 compatibility installers and compressions. (Like FreeArc+SREP+PreComp 0.38 and any more)

2. And newest modern PCs (Core-i3 and higher era) and OS (Vista to Win10) with x86/x64 compatiblity and better maximum compression (FreeArc+SREP+PreComp+RZ+MSC and much more) than older variants.

This very old my repack use classic CMD based installation methods. This game size 7.6GB size reduced to 2.2GB and v2 unfinished version, lower than 2GB file size. (Added more fan made maps.)

Any good idea from best compression?

UPDATE: Testing game compression, use Tiny Compressor v1.4

Used methods: 2 (method 3, this oldschool testing now)

Results:

Source: 19 027 732 495 byte (159 379 files)
Compression time (CPU): ~17700 sec
Compressed size: 4 166 060 315 byte

17.72GB -> 3.88GB

UPDATE2: Method 3 compression failed to 40+ hour long time its my noob errors. Not enough free space from finishing. Pff.

Tested with Method 1:

Compression time (CPU): ~7383 sec
Compressed size: 6 699 140 554 byte (6.24GB)

Any idea how to make setup with stdio (reduced disk i/o) methods from decompression?

Decrypt key

For QBMS

For ttarchext

I'm planning to make may own repack of this game version and have few questions.
Obviously game is encrypted so it won't compress well until being decrypted first. If I decrypt the game first I understand I will get decrypted and unpacked game files – does the game work properly with unpacked files? Is there anyway to compress game with decryption on the fly?
