So we remember the no recoil and clan tag modifications via hex editing on MW2. We remember that if we mod the GPAD0_MP on MW2, we could have no recoil and a unbound clan tag.

I went to work on Black Ops about this. While doing this, I found out that:

Black Ops servers automatically dynamically encrypt a file for download, GRAD0_MP, and save it to your game save. It writes all the mp data then dynamically encrypt, and each time you log back online, it downloads a new file.

So say if you log online and you check your GPAD0_MP, and its like this

And that stores your current clan tag + stats.

Next time you go online it'll be

But when decrypted, it stores your sensitivity (which can be modded for no recoil) and it stores your current clan tag.

If you decrypt the file, good luck. When you log back on its just gonna get overwritten.

With this information posted, no recoil + unbound clan tag is impossible through hex editing the GPAD0_MP.

I didn't refer to it as hacking, did I? I'm sure I used the term "reverse". You are missing a big thing in life. Learning how to read.

Didn't I say they were encrypted? I also said you really can't do anything with them. I hate it when 'omfg im leet" hackers, like you, try to make someone else feel bad. Not working on me.

I really, really thank you for responding, but you didn't have to get like that. I don't follow no one, not even someone like you. I do like your work, as well as geohot's.

So everything I said was near being right or was 100% right. Whats the point in starting a argument when you could of just simply stated in friendly. Your dogs are the ones who pretty much started this. Keep them in their cage.

I dont get why u trying to decrypt an offline file which clearly gets overwritten everytime u load mp. The only way to mod BO is through finding the exact bytes in the patch, this can be made easier using an IDA plugin written by geohot that used to decrpyt the iphone baseband OS.

Notice how you make one post and 7 people thank it lol. Fan boys ftw?

FFS the GPAD is exactly like CoD4(except it also stores splitscreen classes), and it can be hacked. However, I believe the fixes for modding it on the XBox got ported so everything would be patched.

I haven't decrypted it, but that's what it contains.

I quote, "TheUnkn0wn isn't completely smarter than me at hacking." and I then said I AM NOT A HACKER AND YOU REFER TO THIS (Opening a file in some program that you made that OBVIOUSLY wont decrypt the GRAD0_MP.PRF file) AS HACKING. You learn to read, I put them in Bold, Capitals and even added some color in.

You are missing a big thing in life. Learn how to reverse.

Your the one missing a big thing in life, learning to read. You can't get no one without that. I never said that was hacking. Did I even say any of that was hacking?

I know what I'm talking about because I have looked into it. The files are the exact same as the files for Xbox and are encrypted in the same way. Because the saves are also protected by the SONY game save Encryption and Checksum (You cant even change the name of the save in the PARAM.SFO because of the checksum) so you cant do anything with them.



If you have then what is the algorithm used... oh, you don't know or "I'm not going to tell you." they are normally the excuses I get lol

The fact you refer to it as hacking shows you lack intelligence. Its called reverse engineering, the word hack/hacker is used in completely the wrong context these days you find a glitch in a game and your called a "hacker". I also don't portray myself as a hacker either. I think its wrong.

I also hate it when I tell people they are wrong and they go off crying about it. I only say what I say to let you know your doing it wrong. When I learn things on my own nobody ever tells me if I'm doing it wrong I have to figure that out myself, you should be glad you get feedback off people who know what they are doing. I know its just a game but games contain some of the most advanced technology in computer science that can be used to help people (e.g: Graphics engines from games are used to create simulations to see how things would react in the realworld) and create solutions (like the processing power of graphics cards can be used to solve equations to help create a cures Folding@Home) and I'm just someone who likes to learn how it all works because thats the thing I find interesting and I like the engine Call of Duty has because its so simple and flexible and that's why its the best selling game in the world, I don't do it to boast about "HEY LOOK WHAT I CAN DO! LETS ALL ABUSE THIS" hence why you don't see me release anything. The whole reason I come on this forum is to find someone else like me who shares the same interest. Unfortunately I seem to be the only one.

Hunter's what is on here? TheUnkn0wn isn't the only one who knows how to hack Black Ops. I currently don't have the requirements to do so, maybe on my birthday I will.

Sorry, I meant that hunter128 is on NGu but I never see him post. And I'm not saying you can't hack. I don't know you so I can't judge.
