I can't name this as "information". It's just obvious things. I spent probably 2 FULL days trying to locate code which reads b2index file, but without any success. Delayed research to better times - when I'll be young again and will have a lot of free time  |

Would it be possible to look into making UE Viewer work for Gears 5? I figure there might've been development changes / new insights for UE Viewer to possibly extract the assets from Gears 5.

At the moment I can't consider spending any more time with this game. I can't "guess" file formats used there, but doing full research would require fully unprotected and still working game exe file.

Gears Tactics also uses the exact same format as Gears 5 and they both use oodle mermaid. And as far as I know, It doesn't have eac. Working on the Gears Tactics steam version might be an option. Also, I managed to decompress some of the files in the b2container archives with some info that I don't know how accurate is, and the files are somehow odd. I can send some sample files if anyone wants.

Already tried Tactics last Summer, it has the same protection.

So basically, this ends here?

Yes, unless some hacker will remove the protection/encryption from exe, and make the game functional with this executable. Otherwise I'll need to spend months just to dig inside the file format used there.

I am writing a python script that parses the b2index file and uses the info for decompressing b2container files. Here's a sample file that I decompressed. I think it's an uasset file but the structure is a bit odd  . I don't know if it helps anything with exe being still protected but here it is if anyone wants to take a look. |

I'm unsure if it will help, if I'll adapt UModel to handle one file - it might crash with others. So I'd need ALL game's files so every little would be immediately tested with full set of data. Ideally of course I'd need support of Gears 5 pak (b2*) files in UModel.

Okay, when I finish the script, I think you will be able to add the support to umodel. And I started to think that files in the b2containers are not separate uasset files. Some of them are pre-divided pieces of the same file, then compressed and packed into b2containers. I'll let you know when I am able to get the script straight for b2 files.

In Gears 4, there was a complex system behind their pak - some "bundle" system. I suppose Gears 5 extends it and merges with pak.

Yeah, they're pretty similar but not exactly the same. b2index is a complex file but of course it's possible to parse it properly with some time.

I was quite tired of certain removed posts from this topic, so I've decided to make some open source public solution to support further researches. Experimental quickbms script for extracting assets from b2container (Gears 5 format) added to custom scripts bundle at usual places (zenhax or rin). Please note that it's a work-in-progress script and for now it's extracting files without proper filenames. More info here: https://zenhax.com/viewtopic.php?f=9&t=12573&p=64001#p64001 If you have questions about this particular script, please ask them at zenhax forum in the linked topic. Update: Updated script can now extract files with filenames, but without full paths, which are still under testing. |
