2. Why are you using the cyberpunk 2077 precompressor on not cyberpunk 2077?????? :confused::confused::confused:

3. xzlib - we're getting somewhere, but this game is made in unreal engine 3 and is compressed with lzo and not zlib (zlib is ue4) - which is why you need to use UELR [Unreal Engine LZO Recompressor]

I know you write this post long time ago but just to clarify something. Cyberpunk 2077 wasn't made in UE3 as you said, it was made in CDProject's REDengine 4.

The title in question was "Rocket League" though, which was made in "Unreal Engine 3" and not "CDProjekts REDengine 4".

Do not use bpk on Alan Wake Remastered. Pretty much all videos give bad crc on extracting. I don't know if bpk has problems with 4K resolution or codec they use.

Thanks for clarification. I have been confused and trying to figure what went wrong for the whole day :(

Noob questions: This ECM prefilter tested from very old/older game files (like: textures, audio, any formats) compressions? Use before any precompressors or before srep+lzma/lolz compressions? Yes, the filter optimized this CD-image files compression.

Farcry 6 - Precompression

Library used : LZ4 v1.8.2 (Thanks to KaKtor)
Similar results can be obtained from LZ4 that comes with XTool v0.3.9.
XTool Version : 0.3.9
Database : Created using Razor's db (fc6.xtl)

Code:

[External compressor:xtool]

header    = 0

packcmd   = xtool.exe precomp -mlz4+fc6 -c32mb -t100p --dbase - - <stdin> <stdout>

unpackcmd = xtool.exe decode -t100p - - <stdin> <stdout>

Code:

Compressed 1 file, 683,722,320 => 1,286,884,486 bytes. Ratio 188.22%

Compression time: cpu 1.02 sec/real 48.29 sec = 2%. Speed 14.16 mB/s

All OK

Hi all,

Has anyone given "Call of Duty: Black Ops III (3)" a shot? It piqued my interest when I saw the QuickBMS script for "xpack" archives [1] mentioned that the "LZO", "LZ4" & "Oodle" compression algorithms were used within these archives. I'm sure testing which libraries for "LZ4" give the best output won't be too tricky, but in regards to the "Oodle" codec(s) used, I'm a bit stumped. As far as I know a "oo2core_#_win64.dll" is required, with either "xtool" or "Oo2Rec#", to pre-compress a given file, however such a file isn't present within the root and sub-directories of the title in question. Does anyone have any idea how to go about pre-compressing the "Oodle" streams for this title? Apologies if I buggered the terminology.

Well you can check with hex edit if the game has oodle at all (I don't know), if yes then just try all different libraries.

Newest results, from previous months testing:

MSC+SREP: 634 861kB (Use TAK 2.3.0)
MSC+SREP: 634 836kB (Use TAK 2.3.1)

Retested and again use MSC with TAK 2.3.1 and use with any extra switches and goal!!

New Results: 630 595kB!! Nice, few MB's gain from previous versions. Overmaxed WAV compreesion. :)

Tiny SFX compressor commands:

Code:

arc a -lc1024 -ld1024 -ep1 -ed -r -w.\ data.bin -mmsc+rep:256mb+4x4 "Data\*"

arc.ini:

Code:

[External compressor:msc]

header = 0

packcmd = MSC c -v -f -wav=1 -raw=2 -bmp=1 -ddsraw=1 -ddsdxt=1 -mp3=2 -bmf=9s -tak=9 -dxt=2  $$arcdatafile$$.tmp $$arcpackedfile$$.tmp

CRCs are OK! My preference, smallest memory eating, (lower than 768MB/1GB) from during decompress, heavy compressed, repacked games to use old PC's. (Win XP with min. 1-1.25GB RAM or Win7 with 2GB RAM memory.)
