Armored Core 4 .000 files

I was taking a look at the AC4 game files and there are these .000, .001 and 002 files rather than any TCF or FLV files, which leads me to assume these are containers. Anyone knows how to open these?

Here are some samples:

You can unzip the data with the following BMS commands.

Code: Select all

endian big
goto 0x24
get Zsize long
get Offset long
goto 0x8 0 SEEK_CUR
get Size long
get Name string
string Name + ".dcp"
clog Name Offset Zsize Size
Then you can extract the geometry within using hex2obj.
An example for the resulting file hl0010.000.dcp:
hl0010.jpg

Thanks for the help, though sadly I cannot use hex2obj. If anyone is willing to make a script for these files, it would be appreciated.

Now to figure out where the textures are...

Well, you don't want to extract all stuffs manually, of course.
Which platform are the samples from btw? PS3?

They're in the same file though I didn't care for them in the first place.
So here's is a BMS script that will unpack the .000 archives you uploaded, and a simple Noesis script for loading the resulting tpf images.
Only 2 image formats supported currently.
AC4.rar
Let's see if someone would make you a script/tool to load the models. [roll]

Yeah, it's ps3.

Thanks for that, I actually had already used your bms parameters to open a couple of files in search of textures, but found nothing.

It seems the script does not work on the sequential files. I updated the samples file with new samples:

Script updated.

Select only .000 files as input.

Thank you, it works. Now we just need a script to open the models. If no one is willing to do it for free, I am willing to pay.

Anyone? My offer still stands.

No takers? I should look further then.

Some model samples maybe? I looked and made script for one Armored Core game long ago, don't remember which one.

I apologize, I forgot to upload samples of the models themselves.

Hmm, I was wondering which game this format reminds me off, it's some sort of proto version of FromSoftware demon souls/dark souls engine, ninja blade too, I worked on newer Armored Core game, this format is different.

P.S. Can you convert textures from .tpf containers?

Yeah, have a noesis script.

Good, less work to do, also there's two model types .mdl and .smd. They are similar, though .smd look like a collision mesh? No uv's, weights just raw geometry and more low-poly

EDIT: And I will need much more .mdl/.smd samples if I'm going to finish this script. You can skip the .tpf files, just models in order to lesser the size of the sample archive.
