Assassin's Creed Syndicate (.bk2 + .forge)

Post by PlanK69 »

Hey there

So, I've previously been able to convert .bk2 files (which are video/audio files), to .avi using RADTools, but it seems that the .bk2 files on this latest ACSyndicate game is different to previous .bk2 files, because I can only convert the .bk2 files to .avi, without sound. It seems that something is blocking the sound from showing up in the converted .avi file, eventhough RADTools DOES show that there is an audio layer present... I've uploaded 2 .bk2 files for you guys to fiddle with, to see if perhaps you are able to convert it to .avi or .mp4 WITH audio. Here you go: https://www.dropbox.com/sh/fkftxkks3s48 ... N_HWa?dl=0


So that's only the first issue... The 2nd issue is the .forge files that the game uses. I've already tried the .forge extractor that can be found here: viewtopic.php?f=9&t=699&hilit=.forge ,but that program wasn't able to extract usable files. So it seems that the .forge files are different from ACRogue, for which that program was originally intended. So, is there any other .forge extractor that is reliable maybe? Then I can try to use it to extract the .forge files. I want to extract the .forge files because they contain all the sound files and model/art assets.

Edit: I've uploaded a .forge files, incase you want to play around with it and see if you can get any usable files from it, and then I also uploaded a .pck file, which should contain sound files, which if you want to look at it and possibly find a way to extract, then that would also be great (it's the first time I've ever seen a .pck file) Just use the same dropbox link as above for those files.

Videos in ACS don't have sound. All sounds are in .pck files.

Ah well I've actually found that some of them contain sound, but not all.

But it's probable that those videos that don't have sound, would get their sound from the sound files then I guess. I'll look in there.
