Extracting GDI dumps files
by TuxTheWise

Why would you want to do that?
- Make your own rips.
- Listen to music or watch the movies that were ripped/downsampled on the release
you're playing.
- Obtain GD file order to optimize your rip.
- Verify if a image you have downloaded on internet has no corrupted files.

1. Introduction
Have the GD dump files on a directory (track01.bin, track02.raw, etc). The .gdi file is
not necessary.

As  most  of  you  know,  a  GD  disc  has  two  parts:  low  density  (CD,  can  be  read  by
computer)  and  high  density  (only  Dreamcast  can  read).  CD  part  has  a  small  data
track and then a small audio track. Data track usually has useless stu          , but can have
extra  files  like  wallpapers. That's track01.bin. The audio track is the warning track,
the  "warning,  this  disc  is  for  use  only  on  Sega  Dreamcast"  on  american  games,  a
similar message in a lot of languages in european, and "(!*@&#!(*@&#!*(@&#(*" in
japanese games. That's track02.raw. Other tracks are all from high density area, and
contains the actual files of the game.

2. Extracting CD data trac
This is useless most of the time, but it can be done easily by a couple of methods.

2.1. Method 1: IsoBuster
Open track01.bin in IsoBuster ("Open Image File"), select all the files that appeared
(click in one and CTRL+A), right click, "Extract Objects" and select a folder to extract.

2.2. Method 2: Daemon Tools
Have  at  least  1  virtual  drive  created  by  Daemon.  Click  Daemon  tray  icon  and  click
this drive. Now select track01.bin (you will have to select "All Files (*.*)" to make it
show  up)  and  image  will  be  mounted.  Now  go  to  My  Computer,  select  the  virtual
drive and you can just copy/paste the files.

3. Extracting warning audio trac
It's already extracted with the name track02.raw, but you probably can't handle this

                                                1

extension. So use raw2wav (included on this pack) this way:

raw2wav track02.raw

and  it  will  be  converted  to  wav,  that  you  can  listen  and  manipulate  the  way  you
want. Note that this conversion has no quality loss.

4. Extracting IP.BIN
Use isofix (included on this pack) in track03.bin this way:

isofix track03.bin 45000

and  wait  it  finish.  It  created  a  file  named  "bootfile.bin",  rename  it  to  "IP.BIN" and
you're done.

NOTE:  You  can  delete  "header.iso",  but  don't  delete  "fixed.iso"  because  it  will  be
used soon.

5. Examining file order
Open "fixed.iso" created in last step in IsoBuster. If game have multi data tracks, a
red cross will appear next to each file, but don't worry about that.

To examine the file order, see the LBA of each file. Lower numbers mean inner part
of disc. You can put the files in LBA order clicking on the title of the column on top.

If you want to extract a list of the files, select the title of disc in left window, right
click, "Folder tree and file information", "List tree-info (in txt file)", "LBA, Full path"
or "LBA, Relative path", select a directory and a   ile called FileList.txt will be created.
This file has each file and its LBA and can be converted to mkisofs sort file. But that's
another subject and probably will be discussed in another tutorial.

6. Extracting high density data
Before going on, there are 3 kinds of data distribution in high density area and you
must identify which one your GDI have to know how to extract the files.

6.1. Single data trac
Your  GDI  must  have  the  following  files  to  be  in  this  classification:  track01.bin,
track02.raw, track03.bin ONLY (and .gdi file of course). If it has any additional .bin or
.raw file this method can't be used. Examples that  use this distribution: Marvel Vs
Capcom 2, Sonic Adventure.

Open the "fixed.iso" in IsoBuster (that was created in section 4) and files will appear

                                                 2

----------------------- Page 3-----------------------

in the right window. Select all (select one and CTRL+A), "Extract Objects" and select
a folder to extract. You're done.

Alternatively,  you  can  mount  "fixed.iso"  in Daemon  and copy/paste files as told in
section 2.2.

6.2. Multi data track without CDDA
Your  GDI  must  have  the  following  files  to  be  in  this  classification:  track01.bin,
track02.raw,  track03.bin,  track04.raw  and  track05.bin  (and  .gdi  file  of  course).  If  it
has  any  additional  .raw  file  this  method  can't  be  used.  Examples  that  use  this
distribution: Tony Hawk's Pro Skater, Grandia II.

Open notepad and create a file containing this:

FILE "track03.bin" BINARY
TRACK 03 MODE1/2352
PREGAP 10:00:00
INDEX 01 00:00:00
POSTGAP 00:02:00

FILE "track04.raw" BINARY
TRACK 04 AUDIO
INDEX 01 00:00:00
POSTGAP 00:02:00

FILE "track05.bin" BINARY
TRACK 05 MODE1/2352
INDEX 01 00:00:00

and save it with .cue extension in the directory o  your GD dump files.

Mount the .cue with Daemon Tools (note that the files won't appear on virtual drive
on My Computer), open IsoBuster and on top/left corner select the virtual drive of
Daemon. Files will appear on right window. Then select all (select one and CTRL+A),
"Extract Objects" and select a folder to extract. You're done.

6.3. Multi data track with CDDA
Your  GDI  must  have  the  following  files  to  be  in  this  classification:  track01.bin,
track02.raw,  track03.bin,  a  lot  of  .raw  tracks  and  trackXY.bin  (where  XY  is  the
number of the last track of the GDI). Examples that use this distribution: Mr. Driller,
Nightmare Creatures II.

Open  CueCreator.exe  (included  on  this  packType  the  number  of  the  last  track  of

                                             3

----------------------- Page 4-----------------------

data (XY from the description of last paragraph) and a file called created.cue will be
created.  Move  it  to  the  directory  of  your  GD  dump         iles.  Mount  the  .cue  with
Daemon Tools (note that the files won't appear on virtual drive on My Computer),
open IsoBuster and on top/left corner select the virtual drive of Daemon. Files will
appear on right window. Then select all (select one and CTRL+A), "Extract Objects"
and select a folder to extract. You're done.

6.3.1. Batch converting CDDA tracks
CDDA tracks are already extracted under the name o  track04.raw, track05.raw, ... ,
track(XY-1).raw. You can convert each track using raw2wav as described in section 2.
However,  it  can  be  a  time  consuming  process  because  games  like  Nightmare
Creatures  II  have  80+  CDDA  tracks.  To  make  job  easier,  open  BatchCreator.exe
(included on this pack) and have raw2wav.exe and the tracks you want to convert in
the  same  directory.  Then  type  the  track  number  of  the  last  DATA  track  (XY),  not
audio  track  (XY-1).  For  example,  if  your  game  has  track01.bin,  ...,  track06.raw,
track07.raw,  track08.bin,  you  must  insert  number  8  in  the  script.  A  file  called
"created.bat" will be created. Execute this file and songs will be converted.

7. Last comments
Nothing about track04.raw was commented in this text because usually it's another
warning  track  (same  line  of  track02.raw,  but  not  identical  file)  that  I  have  no  idea
why it's there. It can be converted with raw2wav as the other tracks. Usually you can
just delete it after extraction (not before!) because it has nothing useful, but I found
out  that  the  game  Armada  has  only  one  CDDA  track  and  it's  track04.raw.  I  don't
know about other games, so I would convert and listen this file before deleting it.

8. Thanks
- The nice guys who created the programs used here.
- All people that rip and distribute GDI.
- az_bont for writing this guide that helped me a lot.
