Re: Final Fantasy XI .DAT (PC)

It looks like even if I tried to skip the start, I don't know how many chunks there are.

I would imagine I would have to determine what kind of data I'm going to read in, cause for sure the textures are all over the place.

But anyways I got a copy of the game so I can start with some of the smaller files...

EDIT: Ok, so everything is stored in DAT files.

Anyways let's just suppose this is a chunk-based format, where it gives the tag along with 4 bytes that identify what kind of information is stored and maybe some counts

The first tag is always followed by 0x 01 01.
There will always be a corresponding "end" chunk somewhere later.

You can see that the texture chunks also some common bytes following it (0x20)

Having this parenthesis matching makes it easier since now you can just do a while loop and build a parse tree from it.

Everything appears to be 16-byte aligned (judging from the pixel data, unless those 00's at the end are common).

There appears to be a chunk size somewhere. For example if you look at shiryu, the "cse0" chunk has token 0x87.
If you look a little further, you'll see 0xD8 or 216. If you look at the size of the entire chunk, it is about that much.

Now look at the "mse0" chunk at offset 0x200. It also has token 0x87, but this time if you look at the chunk size, you see 0x144, or 324.

Again, if you highlight the rest of the bytes until you get to the next chunk ("mse1"), you'll see it is a little more than 324 bytes.

Thank you, finale00 !

Ah i understand a littte on your words.

Like you said, The .Dat format is "chunk-base format", right ?

And every chunk have its size. The first chunk (cse0) has 216, and futher the next chunk (mse0) has 324.

From here, because all things was stored in .DAT file, so we can split these chunks into piece and some chunk will contain vertex or bones , right ?

But the thing that i dont understand is all of .DAT file have same structure or just some of DAT file have same structure?

I would imagine all dat files have the same structure.
I looked at a couple that were dealing with things like UI, and they were stored in the same way.

Some dat files even have only 4 bytes: 00 00 00 00

The textures are pretty much the same things. You just have to see what pixel format it uses to calculate the size of the pixel data.

This one's on my todo list already, but it's super-low priority. (well below FF12) I haven't played FFXI in years and have been too lazy to install it again to get at the data as well. I only care for the sake of main-numbered FF series completion in Noesis, because I'm a weirdo like that. I had planned to do it in the form of a native plugin as well...but if you're already working on it in the form of a Python script, I can probably assist if you get really stuck.

On a semi-related note, FF14 should also work in Noesis already. Probably. They may have changed the format since the beta, I never bought the game to test it. I recall chrrox telling me that it does work still. But if they did change it anyway, it's probably a trivial change to make the files load, but I'd have to have some data to see.

Edit: I forgot to mention, also, I came across a PDF at some point which completely detailed this file format and even had animation info. I can't seem to find it now, though. But it's out there somewhere, and should save anyone interested in the format many hours of guessing games. If you do find it, please post it here as well.

Final Fantasy its the father and mother of the RPG games, i play the first Final Fantasy in 1985 with the Nintendo, I remember Squaresoft made 2 games to nintendo, one its rad racer a very old game of cars and then made this RPG, because the company are broquen the developers put the name of Final Fantasy to the game like the Final Hope for Squaresoft, now its a big company SQUARE-ENIX, i dont like the fusión and i think the RPG of square lost Quality with the fusión, yest that one with 2 red butoms, and then i play all the final fantasy series, i stop in Online Final Fantasy series coz i really dont like the Online series of this.
If Mr. Adults Already can made Noesis the Official Tool to open the models of the FF series this made the NOESIS a epic tool.

@Mr.Adult It 's hard to find .DAT file structure like you said. I tried to search around the internet 2 month ago but all the link related to FFXI was died. Maybe someone know Japan Language can help us to find .DAT structure in Japanese forum.

Unrelated, but I decided to continue with my MQO plugin for noesis and was testing it on the MQO exports provided.

And here's odin!

Don't tell me they only store half of the model?
Or maybe the export dev decided to store only half the vertices to make it easier for the 3D tool.

And here's half a shiryu...

I think I read somewhere that final fantasy, especially on game consoles where optimized in this way, just storing half models etc. I think I read it connected to ffx on ps2

Nope, FFX didn't use any kind of mirroring. FFXII might, though.

The mirror flag is quite obvious in the Alexander model because there is one object in the model that isn't mirrored.
How the hell do you skin it?

Oh, ya, the towers at the top aren't mirrored lol.

So you've found the flag?

Hmm, so we have a bunch of entries at the top (maybe stuff like bones?), followed by a bunch of textures, followed by vertices, and then followed by faces (which contains mat name as a string, vert indices as shorts, and the UV's as 6 floats)

Another per-face format great...I can see why converting this to MQO was a natural choice just because when I'm looking at it all that comes to mind is MQO MQO MQO MQO MQO MQO

Sorry to necro this, but has anyone come up with a final solution for this? Sadly i can't read or do code, but using all the apps provided like FFXItools, Metasequia, and ModelViewer I can get the model and texture but none of the animations. And really all I wanted was the animations for retargeting. :( anyone have a already coded solution for this?

My friends and I researched this game, but the animation is not complete.
