Updated guide on how to patch the game using the GL6 repository files Part 2 (Dumping the ISO)

I actually took a look at the Growlanser 1 PS1 and PSP game contents, to see what kind of issue other people might have had to translate the game and i came across the problem of file compression. As far as i can tell, both the PS1 and PSP version use some kind of compression algorithm to reduce the filesize of the games ISO.
Because the games (Growlanser 5 and 6) .DAT files do not use any kind of compression we were able to dump the scripts of the game rather easily.

Heres a quick overview on how to compile all of the repository scripts into the game files.

1. Dump the ISO using "Xpert2"
2. extract the contents of the .DAT files with "quickBMS" using the Growlanser script
3. use "abcde" to re-insert the modified script files into the games .SCEN/.SCEC/.STXT files
4. use "quickBMS" to reinsert the modified files into the games .DAT files
5. use "Xpert2" to create a new ISO with the modified files

After dumping the ISO using Xpert2 or some other program you will have the following (on both Growlanser 5 and 6):

SLPM_667.16 is the ELF of the game
SYSTEM.CNF some game config file
DUMMY.DAT dummy file containing dummy data
GL6_BTL.DAT no clue about that one
GL6_CHAR.DAT seems to store the character model files
GL6_FACE.DAT probably contains all of the games face image files
GL6_FILE.DAT contains all of the image files (for example, the games character menu) and some other stuff
GL6_MAP.DAT Seems to contain the map data, also has a file that has all of the different map information stored in it
GL6_MOV.DAT contains alls of the movies without sound
GL6_SCEN.DAT contains all of the games script files
GL6_SND.DAT contains the sound files
GL6_VOI.DAT contains all of the voice data


1. First you have to download Xpert2 and use it to dump the ISO file (a little bit out of date guide but its still pretty much the same):

2 Download quickBMS and extract the it in a folder, put the Growlanser quickBMS script into the same folder.
The quickBMS Growlanser 5/6 script can be found here:

https://bitbucket.org/Risae/growlanser-6-english-translation/src/master/GL%205%20and%206%20quickBMS%20scripts/


3. Use quickBMS to dump the contents of "GL6_SCEN.DAT":

All of the contents of SCEN.DAT will be extracted from the .DAT file.
Now you can pretty much do the following

- We have the repository folder that contains the abcde script files (/GL6_SCEN.DAT/)
- We have a folder that contain the extracted GL6_SCEN.DAT (game) files
- We have the original GL6_SCEN.DAT file

We use abcde to import the repository script files into the original .SCEN files.
And after that we use quickbms to import the modified .SCEN files to the original .DAT files.
(And after that you just have to use armips to import the variable width code into the ELF file)

Repository script (abcde) > original .SCEN/SCEC/STXT (quickBMS) > original GL6_SCEN.DAT (Xpert 2) > dump the iso and switch out the files, rebuild the ISO
