Hey all.

I've been trying for quite some time to unpack GetAmped2's .kxr files. The game is developed by Cyberstep. Cyberstep also developed Onigiri, and surprisingly enough, it stores all its data in .kxr files as well, yet the Onigiri script that I found on this site does not work on GetAmped2's .kxr files.

I discussed this with Luigi, and according to him, "the developers have obfuscated all the header of the archive, that's why quickbms can't find the "kxrf" signature and is not possible to read the rest of the information." Could anyone else possibly take a crack at it for me? I love the game and I would greatly appreciate it if someone could get me into these files.


Here's the bin folder where all the .kxr files are stored. These are the files that are updated with every patch and based on their sizes it's clear that these .kxr files are archives.



Here's the download. The files will be located in the bin folder: http://download.getamped.com/GetAmped2_US_setup.exe

Thanks again.

Ekey- yes, I have already done that and the Onigiri script doesn't work on GetAmped2's files! Any ideas?

EDIT: Also thank you for the quick response earlier! I decided to run the script on GetAmped2's files again anyway and I got this error message:



Thanks again!

You using outdated version QuickBMS. Update it.

Where have you found a so jurassik version of quickbms?!?! (11 May 2010!)
And why don't have you checked the homepage of quickbms first?

Wow! I remember using QuickBMS way back when. My apologies lol! I downloaded the newest version on the homepage and re-ran the script on GetAmped2's files. Like you said before, Luigi, the signatures don't match even though they're apparently the same filetype (.kxr) as Onigiri's files.

Here's an image of the error:



What do you think can be done?

It's not finished but works with almost all the files:

NO WAY. You are a god so far I've only tried one file and it works!! Thank you SO MUCH. Even though I can't really deal with the files inside just yet (they're foreign file types like .scm, .ptc, .agi, .kmd, etc.) this is still a godsend. Thank you sooo much.

There's no way to repack the extracted files into a kxr file, though, is there?

The script is valid for reimporting so you can do that.

That is so, so, so awesome. All I can say is thank you. So after taking a look at the files, I've managed to determine what most of the file types are:

Quote:

.agi = Textures

.kmd and .mop = Models

.scm = The collective data, associates models and textures together, even specifies parameters of sorts. Seems to stand for Script Model.

Do you know where/how I can start in trying to convert/parse these files so that they can be viewed, etc.? I don't want to take up anymore of your time; you have already done so much!

I can't help with the content of the custom files, but I have updated the script to version 0.2 because I have solved the puzzle related to the xor byte of each file.

Amped, posted Fri Jun 26, 2015 1:27 pm (5939)

Okay that's totally fine. I can take it from there, then. If I may, however, what was the "puzzle related to the xor byte of each file"? Your script already seemed to extract everything perfectly.

aluigi, posted Fri Jun 26, 2015 1:32 pm (5940)

The previous experimental script tried to guess the xor key to decrypt the files so a small part of them wasn't correct, while now it's the exact key and all the 100% files are correct.
You should re-extract the files using the new script.

Oh, very awesome. Will do. Thank you so much.

Can you help me please, my modified files do not want to reimport, I do not know if I'm doing something wrong or not. . .

Have you read section 3 of quickbms.txt?

The script is valid for reimporting so no problems there.

Hi Aluigi, when I want to reimport, I can not reimport my file, I can not select it apars by writing its name by default, but it always puts me an error
Help me please :'(

Select the SAME files and folders you selected for the extraction.
Don't try to understand, do it.

I have to select the files and folders that I modified to convert them, do we agree?

No, it doesn't work like that.

1. Are these modified files on the same folder as you extracted them?
2. Have you kept only the files that you have modified and deleted everything else in that folder?
3. Are these modified files bigger or smaller than what the archive in question can handle?

My current case, I extracted the pack files, then put it that it gave me in a single place, then I modify it all and I try to repack everything with the file I modified, Is not like that?

Of course. You just had problems with repacking the file in the first place.
