The format is simple but the compression algorithm is unknown.
Is this the ps2 or xbox version?

Brilleas · Post by **Brilleas** » Mon Feb 22, 2016 4:50 am

This is ps2 version.because I used pcsx 2 to play that game.

Ah.Can you help me?

aluigi · Post by **aluigi** » Thu Feb 25, 2016 4:19 pm

No algorithm = No extraction.

Ah.Alugi I found something about that file format.
It's can help to write script?

Hard to say, can't work on it and we don't know if it's really the compression of those files.

aluigi · Post by **aluigi** » Sat Feb 27, 2016 12:36 am

Just checked the Xbox files, they are the same of PS2

Brilleas · Post by **Brilleas** » Sat Feb 27, 2016 2:57 am

Okay.first.I need to thank you anything about your kindness.
but.I have the last way and last question.
1.If it's not archive.But.It's .dff file with encrypted by SNK.How can I converter it.
2.Can you write this script to support UV Map?

Hi aluigi, I searched some information about this format and some time ago I found a post in the fatduck's chinese forum where codeman made the question if there was a way to unzip/decompress the pak files for this game and he responded it:

"It use a kind of LZ for the compression! the method is in: http://gameresearch.5d6d.com/thread-147-1-1.html (Link down

) I think use comtype 8ing in Quickbms should decompress the files! Most 8ing games in PS2 use Renderware game engine."

I found that the Endian Order is Little Endian and also found this two topics on xentax with more information: http://forum.xentax.com/viewtopic.php?f=21&t=4604 http://forum.xentax.com/viewtopic.php?f=10&t=1387

I hope that this can help, I'm interested in extract 3d models from this game too. Thanks!

How about file form game extractor?.It's model or not?

I think chrrox' script is a MaxScript meaning it's for 3DS Max

Oh.thank you.and everyone for this case.

Ah.I have some question.It's dose't support .pak file?.And how to open it before use .dff file?
