Help with the *.bundle(unity) file

[nbbmcll1994]

Anyone can help me? I think they are unity files, however, the header is "PM03PM03FS" instead of "UnityFS".

It's a bunch of renamed bundles packed together, an initial PM03 then a bunch of concatenated archives with UnityFS replaced with PM03FS (as far as I can tell. I don't know if anything else is different from the unity spec).
There's an xor key in the global-metadata.dat file for the manifests (u32 count, [?32, u32 offset, ?32] * count), I think 110 bytes at 0x29384 works.

I attached a program to split bundles up and rename the header. It depends on the manifests and global-metadata.dat. It's also easy to not use those. But I used them.

Code: Select all

Fenghua.exe <input files/folders> [-o <output folder>] -- <global-metadata.dat>

Thanks for your help. Unfortunately， the splited files can not be opened with Asset Studio as well as UABE， so how to do with it？
