The game files are actually in DATA.cpk, with the script files themselves inside tar archives within DATA.cpk.
After unpacking all the tar files and creating script dumps from the scripts, it came out to be 430MB. 7625 files in 1901 folders. Mental.
So here's my extract script anyway: http://pastebin.com/qwvHJiQF - For python 2.7, not 3.0+
It's a ridiculous mess and I don't really recommend you actually use it, but it's available for whatever "reference" reasons.
To get all the scripts:
Extract all the files from DATA.cpk with whatever program. CriPackedFileMaker didn't work for me and I had to use the QuickBMS cpk script instead. Extract it into some sub-folder. Put the script into the folder, so the filepaths are like:
script.py
files\_dummy.dat
files\BGAE.LBG
Open a cmd and run the script as "script.py -unpack files" (or whatever that folder name is that has the files). This will extract all the .TAR archives into an Unpacked folder. Then run "script.py -e2 Unpacked" to extract scripts from all of the script (*.ssb) files.
You will then have all the script and can edit whatever you want in them text-wise. You can add opcodes to the script for new text boxes, but I don't know exactly what you'd need to add, testing takes way too long with repacking the CPK so I don't really want to spend ages trying. If you do add to the script though, just add the opcodes themselves, so just copy everything from the right of the ::. Boxes need to end with a ▼ character for the game to wait for input, otherwise it just goes to the next line. A tip for finding the actual text in the scripts, look at the first call-0xd you see right near the top of the script, and then skip down to the line with that number, as that's where the "main" text script part is.
After you make whatever changes to the text, you can re-compile the whole Scripts folder by running the script as "script.py -c2 Scripts" and everything will be recompiled back into the .TAR files in a Compiled folder. You can then use those with the other files and build a new CPK with CriPackedFileMaker. Options I used were use filenames, try compression and align to 2048 and that works fine. I didn't try other options or data aligning but they may work too. Put your new DATA.cpk back into the UMD and done.
Also you can extract and compile scripts one at a time instead of doing the whole massive Unpacked\Scripts folder. You can straight up extract the .TAR archives from the DATA.CPK with any standard archive tool, winrar, 7zip etc, it's a common format. Then you can copy any *.ssb you want to work with into the same folder as the script, and you can extract it with "script.py -e1 file.ssb" and compile it with "script.py -c1 file.txt" - I recommend you add some extra part to the original *.ssb after extracting it, otherwise it'll get overwritten when you compile, so just call it *.ssb.orig or *.ssb.bak or something. You can then use that and make your own .TAR. 7zip works just fine for that.
It's not very nice I know, but there we are. As I said, probably better to find someone who can make a proper program for you and handle all this stuff is a much nicer way.
Oh yeah, text should be 2 lines, not 3. Also that font is bleh, at least above native resolution.
Welcome to the forums fellow fuwan. As for VNs you should play, if you want there's a recommendation sub-forum, my own personal recommendations of english translated ones would be, Fate/Stay Night, Tsukihime, G-Senjou no Maou and Grisaia no Kajitsu. Do note that they are mostly targeted towards a male demographic(basically the h-scenes, since these are all 18+ VNs) so I don't know if you would like it all that much.
Oh. My. Goodness. A fellow Durarara!! lover!? *squeals a little*...Well, it's hard not to be a fan of such a good series, let's be honest. I have a feeling well get along juuust fine ^.^
Anyway, welcome welcome to our abode. Talk, enjoy yourself, righteously and valiantly discuss matters of extreme importance with our world class community, or something like that xD
Also, I know a girl named Adrienne, but she's straight Chinese. That's interesting.
OH WAIT. The most important part: Read Tsukihime and Katawa Shoujo. They each are incredible works of art
Welcome to our community, you definitely came to the right place.
Good luck with your translation endeavors! I'm sure you'll get plenty of practice on the many VNs waiting to be translated
However it seems that you are going at it alone on Durarara... If you are the one translating you don't want to have to worry about the technical hacking aspect too (especially with PSP games) Participating in a team, even if it is small, will greatly reduce your workload and keep morale up for the project
Welcome to the forums! Hope you enjoy your stay!
You'll probably need to find someone who knows how to hack VNs, specifically PSP ones which are often an even bigger pain to hack than PC ones. Still, good luck!
Have a moe:
