I was able to get the game dump online and open the "cpk" file where everything is stored. But now I am stuck. There is a bunch of files in formats I have never heard of. One of them is "sound.bnd" so I can only assume that's where are all the quotes are. But I have no idea how to open a .bnd file. If anyone knows how to can you please tell me how? Thanks.

A better place to start would be finding out what the header says, if it says anything, using a hex editor. Things to look out for would be identifiers like: Spoiler: click to toggle Where CRI shows it's a Criware format, and the first 5 bytes identify the type. The 3 there at 0x04 show it's an ADX file. That's an example taken from 2U's sound files. Another thing could be if it's an encrypted or compressed file, such as: Spoiler: click to toggle Where the first 5 bytes show the uncompressed file size, as well as a break in the form of "FF" (which I'm not entirely if the FF is more significant or if it IS just a break?) And it still has an identifier here as well: "MIG001XPSP" This is an example of GIM image taken from 11eyes If the header is gibberish or has no obvious patterns like: Spoiler: click to toggle It may actually be a container that you need a specific program to open.. (or a binary file... but I'm pretty sure something named "sounds" wouldn't be a binary file...) at which case... you're beyond me, sorry.

So I actually found a program that was able to open the file Now I have over 2000 wav files that won't play. I looked into it using notepad and here is what came up Do you know what kind of program I need to get these working?

Things that come to mind could be corruption during unpacking, or some sort of encryption/compression again. Unfortunately, notepad doesn't show much. Could you throw one or two somewhere I could download it and take a look?

Could you throw one or two somewhere I could download it and take a look? Thank you so much I forgot to mention that I got the audio files from an awb file so that could be the file. I am trying to upload the awb file but is taking a LONG time so for now here are a few of the empty sound clips I found inside the awb file https://mega.nz/#!cA5HRRaJ!ruj_jXBUn_rfd40KjMaFqhaYLkg-vtTvVu09_g2Jfbo https://mega.nz/#!gUo2AKjQ!CfvWE0jqOvQOsu12U08OCx76OsRQWihj0oncywaWN7Q https://mega.nz/#!wdYXnbxT!_cZ9TVtfeOpcIePWIKZzIo--v1Qdg8tpQQ3dhz-xAkI https://mega.nz/#!sEB3RTLA!TI-AYgCRh_J4t8sVoqBRFLzjPndk4SzZwXlc5UeUQoY thanks again. EDIT- The awb file is finally up https://mega.nz/#!VQJmHDLR!fPrX8vvKlhmeuELhAFqgagffEUkUmt9YJv2SJ-1ZZhw Edited by logonin, May 30, 2016, 6:40 pm.

Spoiler: click to toggle But more importantly, comparing those wave files to standard wave files seems to have a lot more.. uhm.. noise for the lack of a better term. Spoiler: click to toggle Which makes me thing it might actually be compressed or encrypted in some way. And the error my player gives me is a "parsing error" implying it doesn't recognize the file type as wave despite the header... Which fits the idea of compression/encryption too. There doesn't seem to be any obvious signs of a type anywhere so the quickest way would be just... running it through some algorithms and see if it matches any? You say this is related in some way to a school project? How long do you have to figure this out?

I also asked for help on a forum specifically for game hacking so hopefully they can shed some more light on this. Also this is not actually part of the project but I need the audio clips for my project. If I can't do it within the next few days I will just give up and rewrite the script for it but I must say so far this experience has taught me a lot more then the project itself has lol.
