I did extract the .ARC with this script

endian big
get idstring long
get version short
get files short
comtype zlib_noerror
for i = 0 < files
getdstring name 0x40
get type long
string name + .
string name + type
get zsize long
get size long
get offset long
clog name offset zsize size
next i

and have a files .number and not files .dom, its fine or not?

If i missed something let me know please cuz im new to this stuff. hope this helps some of yall

to get .XET files to open as .DDS files, you need to delete the header of the .XET and replace it with the proper DDS header(DTX1 or DTX5) as well as enter in the proper width and height values into the dds header. to get the dds header just make a new dds file with photoshop and then copy paste

[RandomTBush]

Eh... I was a bit confused as to what to do, but I figured it out now. At least, I think I have.

What's your way of doing it? :D

It involved yoinking a header from a random TEX file I found from Resident Evil 5, inserting it into the MvC3 textures, and then using trial and error with the hex values to make the texture export properly.

can i take a look at the script you used?. if possible

[chrrox]

just paste a dxt1 or 5 header on the files and delete the bytes it used for the header you will see the number repeat several times like 3C or 2C thats all that is needed.

0x10:  0000003C   
       |Header Size|
The important parts for a simple conversion are pic info, id, and Header size
  
  -our goal is to replace the header we have here with one of the dtx headers
  - to do this we need to know how big our current header is so that we know what to delete
  - the header size is located at 0x10 and is a long value(00 00 00 xx)
           -the header size of this file is 00 00 00 3C so 0x00 to 0x3C contains all header information
           -now simply delete this data and your left with the .dds without its proper header but dont delete it yet!
  -before you delete the header you will want to get the size of the image so you don't have to waste time guessing it
           -the image size is the first 6 hex values in pic info
           -calculate the decimal value of the first 3 values(height) and the last 3 values(width)
                     -multiply the first decimal value by 2 for your image height
                     -multiply the second decimal value by 4 for your image width
            -voila, you have your image dimensions
            -Use dtx1 header for textures that belong to models in the game
            -use dtx5 header for textures that belong to the ui or are from the art gallery
             -both dtx headers have the width and height values for the example put in(00 04  which equals 1024 in decimal)
                     -height starts at 0x0C
                     -width starts at 0x10

-also, if the image is using dtx5 then your going to have to do some extra work to get the image to look right
                -use image editing software to swap the alpha and green channels
                -edit each channels rgb values
                        -red channel

Thank you for your excellent guide! It worked perfectly for me. Too bad it is impossible to get models yet.

i'm trying to use this script on xbox360 files

Code: Select all

endian big
get idstring long
get version short
get files short
comtype zlib_noerror
for i = 0 < files
getdstring name 0x40
get type long
string name + .
string name + type
get zsize long
get size long
get offset long
clog name offset zsize size
next i

but i get only 0 byte files

Q: how to unpack correctly

[zaramot]

You need a PS3 version of the game! The script does not work with the Xbox 360 version.
