The key is

0x23989837645C9D28BA58072B2076E895B853A7C9E1C5591B814C4FD2A2D7B782

thanks alot

lipsync isnt worth the hassle... 30 mb and if you compress it you will gain 1 or 2 mb of space

removing voice though saves 1.4 GB per language

I thought you would be capable of finding the key yourself

There's a list of keys and an AES finder application uploaded by Spiritovod on the CounterStrike.RussianInformationNetwork which I cannot link here for obvious reasons. You can use those resources in future.

Or use this, if you don't have an account over there (I update this list every week for DSG)

in arc.ini
[External compressor:bsc]
header = 0
packcmd = bsc.exe e $$arcdatafile$$.tmp $$arcpackedfile$$.tmp {options}

For Pack
arc.exe a -ep1 -dses --dirs -s; -lc- -di -i2 -r -m=bsc:b128:m0 data_bsc.arc _Pack\*

For Unpack

arc.exe x -dpunpacked\ data_bsc.arc

NOTE:
cls version (Shegorat) available in Krinkels for 0.3.1

Thanks, I already know about this, but was corious if it is possible with bsc.exe too, but it doesn't looks so.

I have a very tight schedule these days my friend,
anything that cant be automated or i dont solve in under 5 minutes goes to bin.

BTW Final Fantasy is the worst remake for these past years according to some !!!

let me at least share my findings before i delete this game

ffmpeg -i <emov.file> -c:v libvpx-vp9 -b:v 2000k -c:a copy -c:s copy -y <output.webm_then_rename>

use this on all videos

you will end up with 2.2GB of videos

Can I ask why you used zstd for the "*.mp4" files?

ZSTD is very fast and you can maybe squeeze compression ratio to 98%.

Fast unpack - ~300-800 Mbit on uncompressed data (movies, audio and encrypted data)
