Well...
Code:
- open input file E:\MGS_USA\CD1\MGS\DEMO.DAT
- open script E:\MGS_USA\CD1\MGS\mgs_dat.bms
- set output folder E:\MGS_USA\CD1\MGS\DEMO
- the folder doesn't exist, do you want to create it (y/N)?:
  y

Error: impossible to write 0xf11cd800 bytes (total 0xf11cd800)
       Check your disk space

Last script line before the error or that produced the error:
  10  log NAME OFFSET SIZE
The last file increases the size for no reason. I think I'm a bit clueless at this point...
Or perhaps...

Eh, you have to add the "if" statement to handle the event of a missing findloc :)

like this:
Code:
   if SIZE & 0xf0000000
      math SIZE & 0x3fffffff
      log NAME OFFSET SIZE
   else
      log NAME OFFSET SIZE
   endif

Or this:
Code:
   if END_OFFSET == ""
      math END_OFFSET = FULLSIZE
   endif
I think the latter works.
In any case, I think the problem should be solved now. I still have other archives I have to write the scripts for but that's about it for now.

So what am I going to do if the size of the names vary by each file despite not being referenced in the index size itself?
Code:
open FDDE "whd"
open FDDE "wav" 1
open FDSE "streams.wav" 1
get WHD_SIZE long
get WHD_SIZE_TOTAL long

for CURR_OFF = 0 < WHD_SIZE_TOTAL
   get DUMMY long
   get DUMMY long
   get NAME string
   padding 4
   get UNKNOWN1 long
   get UNKNOWN2 long
   get UNKNOWN3 long
   get UNKNOWN4 long
   get UNKNOWN5 long
   get UNKNOWN6 long
   get UNKNOWN7 long
   get UNKNOWN8 long
   get UNKNOWN9 long
   savepos CURR_OFF
next

Like this, right?
Code:
   get NAME string
   padding 4
Also, call me an idiot, but here's how it looked like after I did exactly what you said.

Okay, I'm almost there...
Code:
open FDDE "whd"
open FDDE "wav" 1
open FDSE "streams.wav" 1
get WHD_SIZE long
get WHD_SIZE_TOTAL long
get DUMMY long
get DUMMY long

for CURR_OFF = 0 < WHD_SIZE
   get NAME string
   padding 4
   callfunction COPYPASTE 1
   log NAME OFFSET SIZE 1
next

startfunction COPYPASTE
      get SIX long
      get OFFSET long
      get FORMAT long
      get FREQUENCY long
      get BITS long
      get SIZE long
      get DUMMY long
      get CHANNELS long
      get DUMMY long
      get DUMMY long
      get DUMMY long
      get DUMMY long
      savepos CURR_OFF
endfunction

if BITS = 0x00000004
   open FDDE "wav" 1
elif BITS = 0x0000010
   open FDSE "streams.wav" 1
else
   cleanexit
endif
One thing to note is that on the GC version, the .whd file has that coeff part, which interferes with the files it`s trying to process.

A suggestion: you can avoid long copy&paste parts of code by putting them in a function to call at their place.
For example:
Code:
...
callfunction COPYPASTE 1
...

startfunction COPYPASTE
      get UNKNOWN1 long
      get UNKNOWN2 long
      get UNKNOWN3 long
      get UNKNOWN4 long
      get UNKNOWN5 long
      get UNKNOWN6 long
      get UNKNOWN7 long
      get UNKNOWN8 long
      get UNKNOWN9 long
      get UNKNOWN10 long
      get UNKNOWN11 long
      get UNKNOWN12 long
      savepos CURR_OFF
endfunction
I use this trick often to make the multi-versions scripts more readable.

Well, the script isn`t quite there with how compartible it is with other versions though... especially the GC version.
See the edited post for details.

On an unrelated note, I want the script to alternate between the two archives based on this argument right here:
Code:
if BITS & 0x10
   open FDDE "wav" 1
elif BITS & 0x4
   open FDSE "streams.wav" 1
else
   cleanexit
endif
Is there any way to do this?

So, how can I find an AES key for these 2 dumped/unencrypted XEX2 files so that I can use it on an encrypted archive?
common.rar

I tried findaes, but nothing happened.

Another question I like to ask is how can I "decrypt" this header(which you can see it as an attachment for later use) of an archive file(STAGE.DAT)?

And yes, these questions came from two different games(Grand Theft Auto IV, Metal Gear Solid 2).

OK, I think it's time for the third question:
So I have this .sdt file I extracted using my very own scripts, and I got this header:
Code:
00000000  10 00 00 00 10 00 00 00 00 00 00 00 02 00 00 00  ................
00000010  10 00 00 00 10 00 00 00 00 00 00 00 01 00 00 00  ................
00000020  10 00 00 00 10 00 00 00 00 00 00 00 04 00 00 00  ................
00000030  02 00 00 00 A0 05 00 00 00 00 00 00 00 00 00 00  .... ...........
Do note though that in that file, the header doesn't reference the number of entries - it only lists them.
So how can I make sure these entries are detected based on the "\x10\x00\x00\x00\x10\x00\x00\x00\x00\x00\x00\x00" string rather than with "set ENTRIES long [number]"(or maybe some other idea I didn't think of)? Also, the last four lines detects the sizes each format has before forming into a full file each...
Code:
math HDREMASTER_FORMAT = 0
math XORED = 0

get SDT_SIZE asize
#findloc DUMMY binary "\x10\x00\x00\x00\x10\x00\x00\x00\x00\x00\x00\x00"
set ENTRIES long 3

for i = 0 < ENTRIES
   getdstring DUMMY 12
   get FORMAT long
next i
get INITIAL_FORMAT long
get BLOCKSIZE long
get ALT_SIZE1 long
get ALT_SIZE2 long
putvarchr MEMORY_FILE SDT_SIZE 0
log MEMORY_FILE 0 0
putvarchr MEMORY_FILE2 SDT_SIZE 0
log MEMORY_FILE2 0 0
Here is the .sdt file in question.

So I wrote this script:
Code:
get BF_SIZE asize
get EXT extension         # in case the format uses the splitted extensions(.bf0, .bf1, .bf2 and so on), might be of some use later
idstring "BIG\x00"
get DUMMY1 long
get FILES long
get ENTRIES long
get DUMMY4 longlong
get DUMMY5 longlong
get INFO_SIZE long
get DUMMY6 long
get DUMMY7 long
get FILES2 long
get ENTRIES2 long
get INFO_OFF long
get DUMMY8 long
get DUMMY9 long
get DUMMY10 long
xmath NAMES_OFF "INFO_OFF + INFO_SIZE * 8"
xmath FOLDERS_OFF "NAMES_OFF + INFO_SIZE * 0x54"
putarray 0 i INFO_OFF
putarray 1 i NAMES_OFF
putarray 2 i FOLDERS_OFF
math OFFSET = -1
math DIRECTORY = -1
math SUB_DIRECTORIES = -1
set FOLDER string ""
set NAME string ""

callfunction EXTRACT 1

startfunction EXTRACT
   goto FOLDERS_OFF
   for ENTRY = 0 < ENTRIES
      get FIRSTFILE long
      get SUB_DIRECTORIES long
      get NEXTDIR long
      get PREVDIR long
      get PARENT long
      getdstring FOLDER 0x40
      savepos FOLDERS_OFF
   next ENTRY
   
   goto INFO_OFF
   get OFFSET long
   get DUMMY long
   savepos INFO_OFF
   
   for i = 1 <= FILES
      if i == FILES
         get NEXT_OFFSET asize
      else
         goto INFO_OFF
         get NEXT_OFFSET long
         get DUMMY long
         savepos INFO_OFF
      endif
   
      goto NAMES_OFF
      get SIZE long
      get PREVFILE long
      get NEXTFILE long
      get ENTRYDIR long
      get DUMMY long
      getdstring NAME 0x40
      savepos NAMES_OFF
      
      math NEXT_OFFSET + 4
      log NAME OFFSET SIZE
      math OFFSET = NEXT_OFFSET
   next i
endfunction
The SUB_DIRECTORIES variable on the ENTRIES argument determines the number of sub-directories. In the case of the first ENTRY("ROOT"), the first sub-directory number is 0x2b0e. After the first one comes a number of references that form a directory tree. Onto the next lines of this script comes the FILES argument. Rather than cover all of the files based on a variable, I want the script to cover the number of files based on a number of SUB_DIRECTORIES an ENTRY has. In short, I want to handle it like this:
Code:
ROOT\EngineDatas\04 Technical Bank\World&co\univers\univ_exec_get_world_key.ofc
Any tips on handling an nested directory tree?
