Super Dragon Ball Z (PS2) .DAT extractor? by DCX at 10:20 PM EDT on May 24, 2016
Hello,
I'm looking for an extractor of Game.DAT for Super Dragon Ball Z (PS2) in order to get the music.

Thank you.

Can you upload the Game.DAT file?

Here's the ISO which states it's 3.96GB but only 837MB can be found on the disc.

Seems like music can be played if you cut GAME.DAT somewhere at 500000000 bytes with HxD and put it in MFAudio, Interleave is 8000 bytes, but since i didn't tried to cut it in correct point playback is glitched. If someone smarter can look at this archive one more time with that info maybe they will work something out with that info. This is probably CRI ADX since game files have CRI_ADXI.IRX module, which is used for that format. Maybe it is possible to cut that .dat to a set of .adx files.

I hope you are still here after those 4 years @DCX.

I have been experimenting with this file a bit. So, rename "GAME.DAT" to "GAME.DAT.pcm", then create a file "GAME.DAT.pcm.txth" (or just ".pcm.txth", note the leading dot), and add the following parameters in the .TXTH file:

codec = PSX
interleave = 0x8000
channels = 2
sample_rate = 48000
start_offset = 0x1ce80000 ## absolute music start offset in GAME.DAT
num_samples = data_size

The music in GAME.DAT when played seems to jump here and there, like 1 second (?) is start-track, then 1-sec is track finisher, then the next 1-sec is 2nd portion, then 1-sec is penultimate portion... like tracking around a circle or spiral. The last audible audio would be the middle portion of track. A proper rip would require separating the 1-sec 2-ch samples & rearranging them in position, so it's NOT properly rippeable, it would need some de-scrambling to make out the music.

The audio data has [78 00 00 00 00 10 00 00] "headers" of size 0x800, just starting each track portion, this may be taken as splitting points. (Should be added to vgmstream as a custom stream? i dunno, some other games might have this type of "spiral" playback.)

In the meantime I have conceived a C++like pseudocode to make playback, maybe extracting a de-scrambled stream. The tracks must be extracted beforehand, using [78 00 00 00 00 10 00 00] as string cut-point.
(Disclaimer: I'm not expert in coding, so forgive me the sintax)

Treating with INT data types

/// for each [file] in {extracted & splitted}

get filesize FSZ # some operation to get filesize here!

STRMSZ = FSZ -0x800    # stream size
NCHNK = STRMSZ/0x10000 # number of "2 * interleave.size" chunks, where interleave.size (ILVSZ) = 0x8000
stream ZZZ = []        # null stream, cummulative (not sure if it's right initialization)
## maybe those "0x10000" could be replaced with "2*ILVSZ", where ILVSZ (interleave size) is defined

IDX1 = 0
IDX2 = NCHNK-1    #initial chunk indexes

while (IDX1 < IDX2)
S1 = playxtr(IDX1) # worker function that extracts/plays the stream for selected chunks
S2 = playxtr(IDX2)
stream output ZZZ += S1 + S2 # the output stream, would require file operations
IDX1++ # to start next in following start-chunk
IDX2-- # to end next in previous end-chunk
end

if (IDX1 == IDX2) # when NCHNK is odd number
S3 = playxtr(IDX1)
stream output ZZZ += S3
end

close stream ZZZ
#Program ends here


function SSS = playxtr(IDX) ## stream-like function
return stream SSS: offset(IDX) ... offset(IDX+0x10000)
## Stream SSS is bytes from offset "offset(IDX)" to offset "offset(IDX+0x10000)" of [file]
## Equivalently, SSS is bytes from offset "offset(IDX)" of [file], with size 0x10000
end function


function P = offset(IDX)
return (0x800 + IDX*0x10000) # position in file/stream
end function

/// next [file]
Pseudocode corrections welcomed!

Someone out here could figure out a BMS script for this, or implement this kind of playback in vgmstream, provided the music files are extracted first.

SORRY I DID THE PSEUDOCODE WRONG!!!
..well, not for this extract anyway
(I'm leaving the previous p.c. if someone finds useful)

The correct p.c. would be the following:

************************************************
/// for each [file] in {extracted & splitted}

ILVSZ = 0x8000 ## interleave size
NCH = 2        ## number of channels

get filesize FSZ # some operation to get filesize here!

STRMSZ = FSZ -0x800 ## stream size
NCHNK = STRMSZ /(NCH*ILVSZ)     ## number of chunks
stream ZZZ = [] # stream initialization

for IDX=0...(NCHK-1), +2 # increments of 2
SSS = playxtr(IDX)
stream output ZZZ += SSS
end
if (NCHK is odd) then NCHK = NCHK-1    #old NCHK never reused ## how to do odd/even check ??
for IDX=(NCHK-1) ...1, -2 # decrements of 2
SSS = playxtr(IDX)
stream output ZZZ += SSS
end

close stream ZZZ    ### stream finalization

function SSS = playxtr(IDX) ## stream-like function
return stream SSS: offset:= offset(IDX), size:= 0x10000
end function

function P = offset(IDX)
return (0x800 + IDX*0x10000) ## position in file/stream
end function

/// next [file]
************************************************

I tracked down some music information in memory if it helps anyone. The rest of the proper information (loop points, sample rate, data size) might be read by IOP memory. Memory addresses below are for the Japanese version.

menu_in.ams (menu music):
0049A074 loop segment if 0x2
0049A078 volume?
0049A07C # of loops for segment before second part plays
0049A080 file name

current music:
005A5E70 loop segment if 0x2
005A5E74 volume?
005A5E78 # of loops for segment before second part plays
005A5E7C file name

function 001BBAC0 seems to process these music variables and other stuff.

Hello

Thank you punk7890-2 for this info - I got a pretty idea of what the game does with the music, plus those findings could be implemented in vgmstream, hopefully.

I took the effort to do some analysis to the header, plus examination on the contained streams, in order to create the BMS script annexed below.

The file "GAME.DAT" has some recogniceable data in it:
@ 0 ...     : some data, graphics, etc etc
@ 0x1ce7f800    : 1st "header" of "music" / start of "music"
@ 0x253fa800    : end of "music" / start of other data / NOT-music definitely! / many trailing 0x0 near end

The "music" part has the following structure:
[header(0)] [s.stream(0)]
[header(1)] [s.stream(1)]
[header(2)] [s.stream(2)]
...
[header(n)] [s.stream(n)]

"header(ii)" is size 0x800, the first 0x10 bytes have the following form:
[78 00 00 00] [00 10 00 00] [ZZ ZZ ZZ ZZ] [XX XX XX XX]
where { [ZZ] } := stream.size.proper /2
and { [XX] } := stream.size / 0x20000
( 0x20000 might be 2*interleave.size*num.channels )
Rest of header is padded with 0x0.

"s.stream(ii)" are the SCRAMBLED streams. AT LEAST they are proximal to the same file (so the tracks are not SPLITTED throughout the music bytes).

stream.size.proper is the data size of the PROPER stream; stream.size is the data size of the PADDED stream (to complete multiple of 0x20000), the padded stream contains 0x0 representing silence or maybe separators (some are exactly 0x10000 bytes of size).
The [XX XX XX XX] bytes are used to get the number of chunks that form the full file stream, and thus their file size. For .txth construction, stream.size.proper := 2* [ZZ ZZ ZZ ZZ] is needed.

With this info I went to implement the pseudocode I gave earlier in BMS. Main assumptions are start/ending offsets of music part, known interleave, and the plugin format.

===================================================================

open FDDE DAT 0
set HDRSZ long 0x800
set ILVSZ long 0x8000
set NUMCH long 2
xmath CNKSZ "NUMCH * ILVSZ"
set MUSSTART long 0x1ce7f800
set MUSEND long 0x253fa800

set POS0 long MUSSTART
append
## findloc POS0 binary \x78\x00\x00\x00\x00\x10\x00\x00 ## search [78 00 00 00 00 10 00 00]
set FILENUM int 0

do

set FNAME string ""
if (FILENUM < 10)
string FNAME + "0"
endif
string FNAME + FILENUM
string FNAME + ".pcm" ## .ams does NOT play/ breaks player

log FNAME POS0 HDRSZ

xmath NNPOS "POS0 + 0xC"
goto NNPOS
get NN long
xmath NUMCHK "2 * NN"
xmath STRMSZ "NUMCHK * CNKSZ "
xmath FILESZ "HDRSZ + STRMSZ"
xmath NUMCHK2 "NUMCHK"

for IDX = 0 < NUMCHK2
xmath POSCNK "POS0 + HDRSZ + (IDX * CNKSZ)"
log FNAME POSCNK CNKSZ
next IDX + 2

if (NUMCHK2 & 1)
math NUMCHK2 - 1
endif

math NUMCHK2 - 1
for IDX = NUMCHK2 > 0
xmath POSCNK "POS0 + HDRSZ + (IDX * CNKSZ)"
log FNAME POSCNK CNKSZ
next IDX - 2

math FILENUM + 1
xmath POS0 "POS0 + FILESZ"

while POS0 < MUSEND
cleanexit

===================================================================

You put this text in a .bms text file, save it, then run it with quickbms, together with input file "GAME.DAT".
Output should be de-scrambled stream files: 00.pcm,01.pcm,...53.pcm, with their 0x800 headers.
The ".pcm.txth" file that should acompany these .pcm files should have this content:

codec = PSX ## ams (ar1ka music stream??)
channels = 2
interleave = 0x8000
sample_rate = 48000
start_offset = 0x800 ## after header
data_size = 2*(@0x8$4) ## using header info
num_samples = data_size


Notes:
extract #29 has bad info for looping/repeat, the sample number seems not correct.
Also, #39 seems tiny bit early in repeat point.
Unfortunately .ams extension breaks the player, so I renamed to .pcm instead (maybe this extension could be added to vgmstream with the info I posted).
