Check your data!" and I have to manually test each files or a batch of files to determine which produce this error. packing the files that produce this error separately to the ones that don't results in a consistent successful decompression however the size is inflated due to them not being de-duplicated together. Currently affected titles that I've noticed are "Assassin's Creed" "III", "Black Flag", "Freedom Cry" & "Rogue". I'll note that I've been using AFR v0.0.1.9, using the "-vr" parameter as well as Srep v0.392, since other versions have produced issues with the "*.forge" files from my experience.
For anyone interested or who's encountered similar issues. I found out the cause of my troubles with both this issue and the immediate post prior to this one. Recently I streamlined and revamped my whole pipeline for packing titles and in the process accidentally included an outdated version of Srep somehow, using an updated version has fixed all my issues thankfully.

Sleeping Dogs Update

Been looking into Sleeping Dogs, and after a bit of discussion with some more experienced/technical tool engineers, I've got to say I'm quite intrigued. It uses a very aggressive "LZ" algorithm, with a given ".BIG" (archive format for the title in question) decompressing to over twice its original size! It also seems the WWise ".pck" files used for audio within the title have the potential for additional gains using "OGGRE"/"MSC". Unfortunately for the former I don't possess the skill-set (yet) to adapt the provided compression/decompression algorithm to be able to parse inputs for use with a chain of compressors, but none the less I think its still interesting enough for others to see.

Attached is a tool suite for processing the aforementioned ".BIG" archives, as well as a sample archive.
Came back to this one after a bit of a break and after learning about xtool's "verbose" mode, turns out LZO is used on the archives, however it seems that no matter what level depth setting or library I use no streams are able to be processed, does anyone know the reason behind this? Attached is an image supporting my findings.

No, in the game does not use LZO.
Тhis is a private(?) LZ algorithm. You can read this thread: https://forum.xentax.com/viewtopic.php?f=10&t=9481

crunch = lossy, not suitable for repacking

I remember reading through that entire thread when I was first researching this bugger of a title, had a hope perhaps the lads over at the Xentax forums had been wrong, and that the PMCQ algorithim was just a fork of LZO. I actually managed to talk to Ekey (a very talented developer who's quite experienced with developing various decompression suites for a variety of titles), but he unfortunately lost his source code for his Sleeping Dogs decompression tool. I'm not sure if you'd be able to answer this but do you know why xtool might be reporting lzo1x streams? Is this just as simple as being an error on xtool's part? Honestly might try again to adapt his original decompression function (which we still thankfully have the source code for) as an xtool plugin, but given my lack of success in previous attempts I doubt I'll make much progress.

No This is a different algorithm.

Yep. False positive detect.

You also need a compress function.

Drat! It's always bizarre how complex some titles can be to properly process!

Thats going to be a fun time trying to figure out, heres hoping its lying around somewhere on the web!

Best compression methods from Stalker: Shadow of Chernobyl?? The game compressibble in smaller than 2-2.5GB's size? (with or without MP files. Multilang version installed size in has ~9.5GB's. Installer smaller than ~3.2GB with INNO only.)

Tested one gamedata archive file (*.db5), in few methods. This db5 archive contents extracted in specialized tools and extracted files compressed again into separated 3 archives and results its bigger than compress the one *.db5 file. Not understood!

File: gamedata.db5
Size: 677 500kB

CAB/LZX:21: 520 571kB
7z: 498 055kB
7z/PPMD: 529 581kB
SQX2: 492 547kB
DLZ only: 456 021kB
OGGRE+DLZ: 462 367kB

MSC only (BMP/DDSRAW/DXT=1): 550 356kB* (archive broken! Any data portions its missing??) --> Crunch in DLZ: 387 155kB (probably false...)
MSC only (DDSRAW=0, DXT=1): 677 377kB --> Crunch in DLZ: 478 327kB

Extracted the db5 file:

*.OGM: 68 290kB (6 file) --> DLZ: 59 064kB (Note: OGGRE+DLZ: 59 061kB)
*.OGG: 174 445kB (2052 file) --> OGGRE: 146 989kB
*.DDS: 446 886kB (1249 file) --> MSC+DLZ: 317 108kB / DLZ: 294 630kB
other: 908kB (17 file) --> MSC+DLZ: 103kB
__________________
Total: 690 528kB --> 523 264kB / 500 786kB (WTF!)

Grim Dawn LZ4 dropping streams

Hey all,

I've been giving "Grim Dawn" a looksie and was wondering if anyone might be able to clear something up
Code:
FreeArc 0.67 (March 15 2014) creating archive: Data.arc
Compressing 1 file, 145,766,328 bytes. Processed   0%
Compressing 145,766,328 bytes with "C:\Compressor_Resources\XTool_2020\xtool_0.6.5\XTool.exe" precomp -mgrimTEST -c512mb -t95p $$arcdatafile$$.tmp $$arcpackedfile$$.tmp
XTool is created by Razor12911

Streams: 1396/14028
Time: 00:00:10 (00:00:36)
Memory: 160 MB (160 MB)

100%
Errorlevel=0
Compressed 1 file, 145,766,328 => 160,143,671 bytes. Ratio 109.86%
Compression time: cpu 0.09 sec/real 10.60 sec = 1%. Speed 13.75 mB/s
All OK
I've tried levels 1 - 9 so far and I only get maybe ~1 additional stream for each level increment, and I've tested essentially every version of LZ4 under the sun, (other versions only resulting in ~<100 streams being picked up), would anyone happen to know if its possible to pick up more streams or is it more likely that LZ4 was used very lightly and the other streams are inconsequential.
