Street Fighter IV .EMB .EMZ

[Itze]

I tried editing the files of the xbox360 version, but since the pc version is coming out next month this should be a nice headstart

The .emb files are simple container files which are mostly used for the unlockable gallery images and menu backgrounds etc.

They contain standart .dds files that can be extracted using the usual tools...

And then there the .EMZ files which are the interesting ones

They are used for the character models, textures and all other interesting files... they are either just compressed or encoded, i couldn't make much sense from the hex :/

I have uploaded one emb and one emz file so you guys can check it out and maybe tell me how i can extract stuff from the emz file

Always remember to upload 2 files for every format you want to extract, from one file its hard to find a format structure...

[cTWOpLaY]

so how did you extract the .emb's? and the .dds's? not to sure what the usual tools are as i've never seen these file formats before and they aren't typical archives..

sry for being so full of questions

[Itze]

i recently got the pc version of sf iv and now we got some files to compare

i've uploaded an archive with various files from the pc and xbox360 version:
http://www.yourfilelink.com/get.php?fid=500636

i found some UNCOMPRESSED files in the 360 version that are compressed in the pc version

And as i thought .EMB files are just simple containers:


here's the main menu background which i've successfully extracted:


.EMB's can also contain other EMB's and EMZ's

the .EMZ files are definately compressed... maybe Z for zlib or zipped? :X

Please help me figuring out the EMZ format, i really want to edit this game

[Itze]

OH MY GOD!!!
I'm so good!

i played around a bit with Luigis offzip and with the following commandline i was able to extract this mofo

offzip.exe -m 16 -a -z -15 bg_main.emz blah 0

Code: Select all

C:\Programme\CAPCOM\STREETFIGHTERIV\up\Xbox360 vs PC\zip>offzip.exe -m 16 -a
 -z -15 bg_main.emz blah 0

- open input file:    bg_main.emz
- enter in directory: blah
- zip data to check:  16 bytes
- zip windowBits:     -15
- seek offset:        0x00000000  (0)

+------------+-------------+-------------------------+
| hex_offset | blocks_dots | zip_size --> unzip_size |
+------------+-------------+-------------------------+
  0x00000010 ...................................................................
................................................................. 268466 --> 460
992


- 1 valid zip blocks found

the byte order seems to be swapped between the xbox and pc version but apart from that my extracted pc "emb" is exactly the same as the one that came with the xbox360 version

gotta play some more now... the first step is done

EDIT:


YAY seems to work with all EMZ's so far

from ryu's common file:
RYU.skl.emo
RYU.skl.emm
RYU.obj.ema
RYU.fce.ema
RYU.cam.ema
RYU.bac
RYU.bcm

Model extraction might be possible

here is a quickbms script
Ill update the file name soon.

Code: Select all

idstring "#EMZ"
get unkown long
get SIZE long
set NAME fname.emb
get ZSIZE asize
math ZSIZE -= 0x10
goto 0x10
savepos OFFSET
comtype inflate
clog NAME OFFSET ZSIZE SIZE

[Itze]

nice!

is it possible to recompress with quickbms so i can try inserting modified files again(first only textures)?

[chrrox]

Code: Select all

#Street Fighter 4 Extractor.
idstring "#EMZ"
get unkown long
get SIZE long
get NAME filename
set EXT string .emb
string NAME -= .emz
string NAME += EXT
get ZSIZE asize
math ZSIZE -= 0x10
goto 0x10
savepos OFFSET
comtype inflate
clog NAME OFFSET ZSIZE SIZE

It is not possible with quickbms but it is just using the inflate compression so another program should do that no problem
have you tried just removing the .emz and see if it loads the emb?

[Itze]

Yeah, it just gets stuck on "Now Loading" forever :/

What program could i use to recompress the emb so it looks exactly like the extracted one before decompression?

EDIT:
OWNED!



No need to recompress the files... just rename the extracted .emb to .emz and the game will load them

You can make texture mods with my infusion program:

[Itze]

I'm working on the models now...



Model editing gone wrong... looks like ryu's fireball melted half her face off :uglyeye:

I also broke her skeleton somehow... as you can see by the hanging arms

[plodtrew]

Is there a viewer for the model files?

[NGboo]

No need to recompress the files... just rename the extracted .emb to .emz and the game will load them

I tried that, but the game crashes.

[Savage]

Nice one! the compression used it's gzip, lol

[plodtrew]

Texture editing does work quite well, thanks to the programs posted here. A model viewer would really help in doing texture mods so that the game doesnt have to be started to view texture changes. This is my basic Zangief mod:

Excellent work done here!
