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

Someone checked "Atlas Fallen"? Looks like it is compressed with lz4f. XTool detects the streams but is not able to process them.

I tried with the script "thesurge2.bms" to unpack the files selecting the "toc" but quickbms gives error:

Just use -mlz4f,l2

Code:

Compressed 1 file, 9,574,907 => 34,654,139 bytes. Ratio 361.93%

Compression time: cpu 0.02 sec/real 1.04 sec = 1%. Speed 9.18 mB/s

All OK



Extracted 1 file, 34,654,139 => 9,574,907 bytes. Ratio 361.93%

Extraction time: cpu 0.02 sec/real 1.08 sec = 1%. Speed 8.86 mB/s

All OK

Edit:

Code:

[0] Processing lz4f stream at 0000000000000000 (1522893 >> 2066084 >> 1522889) using l2:b5:d0 has failed

There are just a few bytes which not match, so use xdelta library for precompressing and decompressing.

Atlas Fallen

*.dat -> xtool:mlz4f+srep+lolz [22.2GB >> 15.3GB]
*.webm -> mpz_pmt [3.15GB >> 3.10GB]
Rest everything -> srep+lzma

I also think audio\speech-german.fsb is a language file and can be skipped, or included in additional components. I'll run some checks on language and update

I was compressing some *.big files and it was in a sounds folder, so i tried to use a media compressor and i run some tests

When i used the media compressor ratio is like 70-80%
When i was not using them i was getting 10-20%

This heavy difference is due to encryption? If anyone knows any tool to decrypt this file please share, these files are commonly found in EA Games

These tools will be useful i myself earlier found such a tool but it could not only decrypt it but not pack them back after i am done with recoding

@Fak Eid

Webm container supports only vorbis/opus audio.
Mpz is not for compressing such files! Ok,you gain some megas.
Btw mpz can compress almost everything with little gain. (In my experiences)

Edit :
Sry for "spamming". :)

-------------------------------------------------------------------------------------------------------------------------------------------

 15:43:13 - Overall input size: 46.96 GB

 15:43:13 - Overall output size: 36.96 GB (Ratio 78.70%)

 15:43:13 - Overall conversion time: 01:37:21

 15:43:13 - Overall conversion media: 1 custom media

-------------------------------------------------------------------------------------------------------------------------------------------

 16:04:51 - Overall decompression time: 00:21:31

 16:04:51 - All files have been successfully extracted!

For USM videos you can use bcm.
zstd for AWB files performs best if you don't want to deal with them in other ways.
