Need help understanding PSP VN scripts

[nyxlucifer]

Hey there, I recently got a PSP VN called Corpse Party and thought would be a cool stuff to learn Japanese too (OCR issues btw). I tried decrypting and extracting contents, and got SCRIPT files. But they are all jumbled, I could not find any pattern on where scripts start next, they all are divided into individual map scripts. I tried searching "SCRIPT" string in EBOOT.BIN and all (hey! It might be encryoted I don't know!) but there was nothing. So anyone has an idea on it? It would help me a bunch to go through it comfortably

EDIT:- Here is one of map SCRIPTs https://drive.google.com/open?id=1ym8me ... h3X5I3WqKC
There is also some sort of MAP data associate with it in this file https://drive.google.com/open?id=10pCfA ... Us7YWMfLuy I can't understand it, but I assume it has to do with boundaries, or maybe also on triggers?

Also, I remember seeing "source/VisualNovelEngine" or something like that in decrypted EBOOT.BIN. What's that? Is it something included in all PSPs? If yes, where can I get more info on it, so I can make use of it, and understand how these files are being used

Better if you upload one of these script files so the other users can take a look at them.

What you mean exactly?
It looks very comprehensible.

When playing game, I was lost for a while because after SCRIPT4,0 it didn't execute SCRIPT4,2 but SCRIPT6,0. It had me lost for while because those two are not very different and I confused where some bits go. So this is what I wanted to know, which part of game's files control this behavior of executing SCRIPT4,0 and then 6,0, then go up to 22,0 then 22,1, and such

Sorry for the shameless bump, but I needed to add this. I looked through IMAGE.BIN which should have had all data though maps seem to be missing. Also, the EBOOT.BIN had string like "source/visualnovelengine.cpp" as mentioned before

I think maybe SYSDIR/DATA.BIN has them? But at same time, I have heard many say it just has firmware/update things. Is there any way to decrypt DATA.BIN file? It has a PSAR signature bt

EDIT:- After lot of searching around, I think it's all just encrypted. Would require reversing game to get the files. I might try it someday. But for now, this is it. I will just use script and read some Japanese now

PSAR is covered by the following script:

You can try it, maybe it works.
