[PSVita] Star Ocean Second Evolution (*.psarc)

[chrnodroid]

Hi, anyone have some idea to how to unpack this archive?
It's not a simple PSARC file, because I've tried many tools, like PSARC Ectractor, PS3_PSARC_GUI, Total Commander (psarc_v1.4) and QuickBMS (brink.bms).
Seems like this file is encrypted, maybe with some tri-Ace algorythm... Or maybe there is a specific tool for Vita psarc files?


This is the file, very huge, I'm sorry, the entire game is packed in a single archive.

Sorry for the up, I really want to undub this game, but I still can't open this archive...

There are other posts about psarc.
With big files like that one I suggest ever to use the filecutter script first or probably nobody is going to download it:

Thanks for the script.

I've found a topic about the same game, but there are informations. I've searched in other forum, and seems like there are other users with my same problem.

I apologize that these days I'm writing a lot here about the extraction of some recent tri-Ace games, maybe I'm annoying,
I ask you if you have the quickbms script for the decompression of the SLZ new type 3 code. You called slz_03b, this: viewtopic.php?p=45696#p45696
Or better if you can update the slz script 0.2.5 with the new type
I really don't understand how to convert the C# language to bms inscruction

Thanks in advance

Ok, it's all encrypted so it's normal that no script works on it
Hopefully someone used to Playstation can give you some hints

run this cmd command into the same folder where psvpfstools was extracted.
dont forget to edit putting your folder configs.

psvpfsparser.exe -i "path to input folder\PCSG00714" -o "path to output folder" -z "KO5ifR1dQ+d7BQBdAbPF3NAEZL8BGsDnv/o3N46tPnhWMstka/+KYHPF0Rgf3AAA+34T/AAA" -f http://cma.henkaku.xyz/
