    extract CG/img data for game

    Hellow everybody!
    I have a concern regarding the following software: Crass / arc_conv / Animed
    A Russian in my past, but I do not know how to use them in order to extract data from a otomate PSP game.
    Examples of game already extracts:

    This is the kind of thing I would like to recover ...

    Here are some screen of the game in question that I want to extract:
    http://img11.hostingpics.net/pics/142071ex2.png
    http://img11.hostingpics.net/pics/159741ex3.png
    As you can see, I do not really know if I should use to extract ...
    I frame in red, I thought was the data folder of the game (which, where are the pictures) But the trouble is that it is in bin format. I have no idea what to do.

    Does someone could explain to me the steps?
    Thank you in advance!

    I apologize in advance for my English ....

    Re: extract CG/img data for game

    PSP game, which is dependent on the developer and is not as easy as extracting PC game. You need to know how to reverse engineer, use quick bms as well as UMDGEN.
    I already extracted Amnesia crowd Sprites and BGs before. I need to check my HDDS again, because it's been years...lol.

    edit: never-mind, I already wiped the files.

    Here's the tutorial on how to extract from OTOMATE PSP iso
    http://cadavaberry.tumblr.com/faq
    and here's Amnesia Crowd Sprites and CG
    http://cadavaberry.tumblr.com/post/48287313179

    PSP encryption varies from developers, so there's no quick and easy route to extract it's data.

    By cons for PGDecrypt I do not really find the link to download it.
    I install something else that I think is this:

    But I do not quite understand is that I had to write '_'

    Ahh, this is why psp isos are such a hassle if you have no background with reverse engineering.
    Extract ISO contents using UMD Gen
    Look for INSTALL.DNS and check if it has a pgd or cpk header using a hex viewer like HxD.
    If it's as CPK. Rename the .DNS extension to .cpk. Use Aluigi's .cpk script to extract it.
    If it's a PGD use PGdecrypt. I forgot the commands to use but it should be there in cadavaberry's tumblr.
    Anyway you get a bunch of files and use a hexeditor again to check the file headers, depending on what type there another line of tools to use again to decrypt such files.

    It's a .PGD. ...follow the rest of Cadavaberry's tutorial for the command line for PGdecrypt

    Re: extract CG/img data for game

    There is, all you had to do was scroll down and read

    Taken from Cadavaberry's tumblr and slightly edited and added links for convenience
    -Next, download a program called PGDecrypt. You must use command line with this tool. Like, cd [the location of the PGDecrypt folder], then pgdecrypt.exe INSTALL.DNS. Once you’ve done that, you will get a 0_INSTALL.DNS file that is actually a CPK file.
    -Get aluigi’s quickbms if you haven’t already. Rename 0_INSTALL.DNS to [whateverthefyouwant].cpk. Actually, you probably don’t need to rename it, but do it all the same. Pop this file into the same folder as quickbms (click on quickbms.exe and follow the instructions) and stuff should start extracting.[CPK unpack for QuickBMS]
