[Request] Dirge Of Cerberus Final Fantasy VII models

[falconcool]

Thanks a lot FurryFan,great job^^b
According to the pattern you found.
I pick a little .map data as sample..less complexity
maybe it can help you figure out the
remaining unknown float/variables


File is here
http://www.mediafire.com/?i1uxmt030bi5u1h

[FurryFan]

Yes I will work on it. In English the first part of the file is called the "Header". It should be no problem I have a little bit done and will get the rest done soon.

[falconcool]

FurryFan,,do you think .mod extention is another type of container?
Because all .mod header have rfd and bmd with lots of small chuncks you found
,and not every xxx.mod have the same xxx.tex with them.

[FurryFan]

Yes there is some overlap in the different files. I'll work on the header today after classes. I already made some progress on it.

[FurryFan]

The following applies to most if not all of the MAP files:

The 4byteoffset at 0hC is the size of the file.


The 4Byteoffset 0h68 is the number of 4byte addresses (lets call this OmegaList until I figure out what it is for) in the list that the pointer (add+0h30) at offset 0h74 points to.

The 4byteoffset 0h6C is the number of 16byteFloatoffsets in OmegaFloats that the pointer at offset 0h70points to (add+0h30.

The 4byteoffset 0h1D0 is the number of 4byte addresses in AlphaList that the pointer at offset 0h94 points to (add+0h30)

About the .rfd extention,I noticed there is a file called effect.rfd located in /data/effect/ folder.
Perhaps it's only a function of light effect something being used by the map scene,anyway,,i put that file here.

Another 4 rfd files found in data/etc/folder

They look like some kind of texture format though.

[revelation]

i was starting with the .mod file but seems the format is global to a number of others as well...

Code: Select all

struct MOD_HEADER
{
	SetBackColor(cLtBlue);
	// 0x00
	char   fileTag[8]; // 'model'
	char   dataTag[4]; //
	uint32 dataSize    <format = hex>;
};

The data tag member determines what is contained in each section, with most files starting with a 'rfd' section, which is simply a list of data offsets...

Code: Select all

struct MOD_RFD_DATA
{
	SetBackColor(cLtBlue);
	// 0x00
	uint16 dataCount;
	uint16 unknown0x04            <format = hex>;
	
	SetBackColor(cLtGreen);
	uint32 dataOffsets[dataCount] <format = hex>;
};

The offsets point to another header structure which again the contents of which are controlled by the data tag, 'bmd', 'mod', 'tm2', 'chi', etc...

Hope that helps for now...

Sorry to bump, any new progress with this?

Ok so I've been reading around on another forum, and the files that are extracted here are just garbage. The FF13 script is totally different to Cerberus, so we get junk when we extract.

Apparently we have to use a program called offzip to extract them, has anyone got this tool and know how to use it?

[shadowmoy]

i converted a texture but they are swizzled so there is no interest in getting models witout textures

[falconcool]

Here are 2 new samples ,,one is extracted by offzip,,,the other is dumped from emulator(pcsx2)
You can compare their pattern.

I can't tell float's pattern, it seems to be encrypted.It has a strange array in the front of each vertex chunk,8 bytes each.Don't know what's the purpose.
Could it be bit-rotation? Or maybe half-float?

[jaden]

I hope we can extract the model

[ultimaespio]

Part of the Header of extracted.dat says evm. Not sure if that is a model, I've heard evm somewhere but I can't remember where...

I'll look others,,was digging "MOD" ones only.
Makuchan said he had seen successful extrated model in Final Fantasy Project forum.
http://ffproject.net/

but sadly it's closed atm.

I've never seen though,,,Does anyone know how to contact with the owner of that forum?
Maybe he has some old data stored...

Btw,here are 2 new samples i found,,i believe one of them is the building..take a look if you're interested.

Wish I could offer some help. I'm surprised nothing has been found with Japanese blogs, as I recall it took a tool created by someone in Japan to extract the movie files from DoC.
