(adsbygoogle = window.adsbygoogle || []).push({}); I'm reposting my thread I made awhile back. This is the Original thread.
It is not a copy. I was the one that put the way of doing this out. In turn meaning that none of all these MW2 stuff would be going on if it wasn't for me releasing this awhile ago.

[multipage="Introduction"]
This does not work with every patch. I don't know why. But I have only got it to work on certain ones myself.

People are trying to claim they showed me how to do this. When in fact they did not.

I DID learn from 2 peoples tutorial on here. "Learn From". I took the knowledge they gave and tons of trial and error and got this far. No one, showed me step by step and I did NOT copy anyones tutoral. So, I'm adding the names here so everyone knows the truth.

The I wouldn't have figured it out without you two putting out the knowledge that you figured out.

Those are the only 2 that taught me anything. By following their stuff and trial and error.

[multipage="Conclusion"]
I really hope this helps. If you have questions please ask.

Please, do not flame. It took me nearly 3 hours to type this tutorial up.

It has what I would say very detailed information. More than enough to be able to figure out what to do next.

If you ask for help. Please don't quote this. It is really long. And it will stretch the page crazy long.

Just post. People will try to help.

Hope you enjoyed this. But mostly, I hope you learnt from it.

Remember this is to TEACH YOU. This isn't ment to show you everything to type in. But you will know how to fully edit after you have learnt this.

use HxD hex editor.

You must login or register to view this content.

You should be able to follow the tutorial just fine using that.



You can use this method to open the patch up to put the codes in it. Now, you just have to find the codes. Open a patch up with that code, copy/paste it into the patch you want the code in, etc.

Hes right, people may have done it before but no one got the word out so AlabamaHit was the reason why it became the global hack on MW2

Yeah, how long did this take you, it takes forever let alone just doing this to edit a patch.

Hi ,

I have a ps3 slim 3.66 . Is it work ?

Thanks

You do this on your PC. and after that you DT from a JB ps3 containing the patch to another ps3 you want:y:
