Good afternoon! I've been trying to get some info about best .wad files compression method in Batman Arkham Knight, but i've found very little info on web and nothing on fileforums site.
Is there any way to massively losslessy compress (and decompress) these files? I've tried almost every tool in Diskspan, but the only good compression mask seems to be to usual srep + lolz.
Tham you in advance!

Send some samples here, so we can tell you something usefull

I'd like to compress all .wad files, not specific files. So I don't know which file I can send you.

[KaktoR]

Looking on steamdb, it seems that these files are actually sound files. But I don't have the game so I cannot say for sure, just looking at the file names it seem to be sound files actually.

Maybe wwise in some unreal engine format or whatever. Cannot tell you anything about it.

Not to mention this is just pure awkwardness - if you want help to compress all the files, upload a small one so we can at least see what type of file it is rather than giving some dumb excuse. File Extensions mean nothing, what you really need is a Hex Editor to see what the file actually is.

Something like

BmGame/CookedPCConsole/SFX/SFX_4.wad

Might be good.

WWise Ogg, can be processed manually by Oggre, check Masquerade's tutorial.

Average gain ~10% of initial size.

are you sure? How can I use wWWise ogg procedure on .wad files? I've tried to use wemtool, but of course the exe file found nothing.

Currently I'm taking a swing at the various Quantic Dreams titles that were given a proper PC release, however I've run into a bit of a roadblock. The archives for these titles are only compressed with a basic zlib/deflate algorithm, with XTool being able to process the vast majority of streams.

Unfortunately unlike every other title I've worked on, even the localised Vorbis audio is compressed within these archives, leaving me stumped on how to rip it to make the various localised packs into selective offerings.

Currently the only method I could think to exploit was decompressing the archives as a singular block with XTool, blanking out the offending data and then try and restore the block, however, as I feared I was only met with decompression errors and was unsuccessful.

I should mention I the QuickBMS scripts for Quantic Dream titles doesn't work at all with any of the PC ports that I tested, making for scanning compressed blocks with QuickBMS currently not possible.

Has anyone had a similar problem, and if so would such an individual be willing to share their solution, I'd greatly appreciate it, these blasted titles are doing nothing but keeping me awake at night!

Thank you very much.
Can you also suggest compression methods for FLAC files (for DLCs)?
