Jet Set Radio 3D Data

I hope this isn't agains the terms. If so, please forbid me and lock the topic. The fact is that I am really interested in the models used in JSR for building the cities so I began exploring a bit games directorys in search of "SOMETHING".

JETRADIO dir is the one containing music and 3d files I presume...So I began exploring it. ADX files represented the music so there were strong chances of the 3D files being inside the AFS files there.Besides the names were quite curious:

E:\JETRADIO>dir *.AFS

Volume in drive E is JGR_ECH

Volume Serial Number is 8BD3-D957

Directory of E:\JETRADIO

95 File(s) 345,700,352 bytes

0 Dir(s) 0 bytes free

Anyways I unpacked the data inside the AFS files and in some cases I was even able to extract texture data:

http://img131.exs.cx/my.php?loc=img131&ima...ea200...

http://img131.exs.cx/my.php?loc=img131&ima...ea200...

Anyways, although that was easy due to the format being PVR...I really don't know a lot what to search inside the other files...

My main idea was to look for 1.00000 float values which I would consider W coordinate...and from them deduct the X,Y,Z coordinates...I wrote a program for it (it's not very difficult) but well...the results weren't very good.

Any ideas on what formats could be used to pack the 3D data ? Header hexs ? Thanks in advance.

The 3D format could be anything, sorry. I think it's common for console games to have 3D models in a format that favours loading speed than readability.

This means there are good odds the 3D model files are in a format that is very close to what the 3D engine uses internally, so they can be loaded into RAM with little to no parsing/processing required. The binary files might be full of "garbage" that stores the actual data structures to be loaded into RAM.

I don't know if I'm turning you off or giving you some useful tips...

Yes, I considered this (and not, you aren't turning me off).

Hmmm...But even though...A float is a float no matter how it's coded.

If at least Chankast offered a Debug mode...I could find out more about the format

There was some guy at the Sonic CulT forums... who managed to crack the 3D model formats in Sonic Adventure, Sonic Heroes and NiGHTS, perhaps he can be of help.

Ok, I'll ask them there.
