How do i extract the files from onechanbara kagura

[dj082502]

Hi, all
I'd like to extract cat file from Onechanbara Z Kagura.
May be cat file is encrypted.
the first 4 bytes

Code: Select all

.х.н

Could anyone please take a look?
Here is a sample.

copy&paste from another post of mine:
---
job for xbdecompress.exe (Xbox SDK)
when you see a file that starts with the bytes 0f f5 12 that one is the tool you need

remember these 3 bytes and make it your new religion because you will see them a lot in many x360 games :)

O.K. I'll be more careful.
It combines decrypted file and encrypted file in a single file, and fix the title, so just calm down.

nice... i see see obvious index and vertex buffers. i'm sure somebody is gonna reverse this one soon. looks easy peazy.

Geometry very easy to find. Wonder if the textures are swizzled...

[chrrox]

they are swizzled but they are standard xpr files.
just use the sdk tool unbundler on them

Really fast.
How to extract *_.cat file?

@howvie : great job you've done there !

I also managed to get the mesh's vertices just like your picture.
However I'm totally clueless about the UV coordinates data, have you locate them??

[howfie]

Did you try normalized unsigned shorts for uv coords? Also try to read vertex data that is not word aligned. If that doesn't work try looking at I think Surveyor's old Onechanbara thread; it might use a similar vertex structure and there might have been a trick. I don't have too much time to work on this. I am working on like 3 other games atm. I did the above in like 10 minutes just to try out the xbdecompress thing.

Thanks for the hint, I'll check it up right away!
And Good luck for your work on those 3 games!

actually i am about to give up on finding the bones on tekken hybrid, so if you get stuck let me know so we can bash heads on this one. i am currently redumping onechanbara from my home machine so i'll take a look again at it sometime tonight. btw welcome to the forums.

[gggrrrhhh2000]

The UV is written in unsigned shorts indeed, just need to normalize them to view properly (thanks to howfie).
Now just need to find the Material id and split the UVs.

About the textures, I decompressed them and can see the "XPR2" Header from the Hex data.
But strangely, I tried "XPR Express" "MiteeXpr" "XPRextract" tools, none of them were able to extract the .xpr files into .dds textures as written in the hex.

Anyone has an idea?

EDIT :
After hours of info searching, Those tools above seem to work on XPR, but these textures are XPR2, that's why they didn't work.
Finally managed to extract these XPR2 files, using the xdk tool unbundler.exe. (Ah, chrrox mentioned it above, how could I miss that )
