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

[Masquerade]

Hi guys, I'm having a bit of trouble with some LZMA streams and I was wondering if anyone can give a couple hints or tips at trying to replicate the compression on the original stream close enough to a point where I can make a HDiffPatch.

Decompressing the streams is not an issue.

I've tried a few different tools, namely plzma and QuickBMS yet neither can produce accurate results.

I have attached a sample below.

stream.lzma = the original compressed stream
stream.decompressed = the decompressed stream

This will patch out these optional files in a few minutes.

Good attempt at using xtool IO functions, however since most people wouldn't know where these files come from or how to get them, maybe post the database file which can be used to obtain the files to be erased. The database file can be generated by using the find function from your end.
There is an example I made here.

[:( Sad8669]

Thanks for heads up, Razor.

I had it in my mind the same day you posted the update. I haven't tested the game or the new update in practice but it should work and i plan on writing a post maybe explaining it and other few things about optional language streams.

and you can just write "Sad" instead of that "8669" and ":(" :D.

If you want to make a repack of God Of War and plan to separate voiceovers, add this batch file into your archive and run it after extracting the archive.

(copy text from this paste and save as .bat)

https://paste.ec/raw/ybelA-oU#P-/KOJ...rmyGZdyZvIGZ9b

The game will crash if you try to change language to a voiceover that you don't have installed. This bat will check for whatever languages are installed and add them to the language text file accordingly.

Please note exec\languages\LANGS_GOWA08000.txt must be blank before running that batch file.

You could add break or nul command to clear the file first, then add the content

break>exec\languages\LANGS_GOWA08000.txt

This command makes the target file blank.

How are EDGE OF THE ABYSS AWAKEN game files compressed and how to decompress them. Unreal engine.
