(adsbygoogle = window.adsbygoogle || []).push({}); Hi,
How do I install/edit GSC code scripts?

There seems to be a lot of secrecy about it.

I see lots of sample scripts but how do I put them onto my PS3??

Thanks in advance

From what I understand I must decrypt my PS3 HDD using PS3 HDD studio, modify the scripts and then encrypt the HDD again.

Is this correct?

Is there an easier way to do it?

Good luck , but no one has really found out how hunter and theunkn0wn did it but keep trying

Lots of people must know how, there's load of GSC code around?

Is this because its easy to do on Mw2 for PC or something?

Ok, well I do not want to take my hdd out of my ps3, so I am going to see if I can find another way.

A couple of things I am exploring to get access to the file system:

-PS3 Data Transfer Utility
-System backups
-Internet browser exploits
-Media server connection

Ok I have tried uploading a PS3 pkg to a web server and then downloading it via its Web Browser, but it only allows you to save it to a USB drive, not the actual HD. So that's not very helpful, I will keep looking into this.

wow that theory was proven wrong.

You are a great help kane212

Ok, Im making progress.

PS3 patch can be downloaded from here:

You must login or register to view this content.

Have you tired this? What did you do? What happened?

Loads of people have tried it including me, and have gotten nowhere. You end up with script errors an such.

Ok, I believe that I should be able to decrypt the patch using the offzip / packzip program.

I am using this command to unpack it:

    offzip -a -z -15 1.pkg data 0



and this



offzip -a -z 15 1.pkg data 0

But both commands gives me the following error:



Any ideas?

Moved to hacking questions.

Ok I believe that I am moving forward with this.

A proxy server is used to inject a modded patch.

When installing a moded patch I get the following error 8002AE22. I think this is due to the fact it has the incorrect signature / checksum.

Im not sure if the signature/checksum is actually stored in the patch or from a file it retrieves from the PS3 networks servers.

If patches signature is stored separately it should make it allot easier.

The PS3 contacts the following sites when installing an MW2 update:



Im wondering if the signature is stored on a secured server hence it connecting to a0.ww.np.dl.playstation.net:443

Will have to look into this with wireshark.
