(adsbygoogle = window.adsbygoogle || []).push({}); Hello everyone

Schaos posted a tut a long, long time ago on how to do this but he has since removed his post I know that this would help a lot of you out so here is a tut on how to change dvars in the EBOOT.BIN file. Let's get Started

Requirements:[/u]
-IDA Pro 5.2 or higher (I would post a link, but that's considered warez)
-IDA Plugins & Loaders for ps3 (You must login or register to view this content.)
-HxD Hex Editor
-Black Ops 1.02 Debug Update (You must login or register to view this content.)
-Any program to encrypt/decrypt .BIN files, I use PS3FOXX (You must login or register to view this content., thanks to Max88 for the download link)
-A ps3 on firmware 3.55 or lower

Now we can get started

1. In your black ops debug update, go to BLUS30591/USRDIR/. If you want to change the EBOOT for single player, copy the EBOOT.BIN onto your desktop. If you want to change it for multiplayer, copy the t5mp_ps3f.self onto your desktop and rename it to EBOOT.BIN. In this tutorial I will be doing it for multiplayer.

2. Run PS3FOXX.exe. Click ok.

3. Go to step one on the program. Click "Generer". This will generate the NPDRM keys.

(Thanks to Max yet again)

4. Go to step two on the program. Select your EBOOT.BIN that you put on your desktop. Decrypt it.

5. There will be a new folder inside your PS3FOXX folder now, the name will begin with UNSELF. Go into that folder and open the out_eboot.elf in HxD. Minimize it, you will need it later.

6. Launch IDA Pro. Click ok, then new. A window will appear prompting you to open a file. Click on the various files tab, then unknown file. Open the out_eboot.elf from the PS3FOXX program.

A window will open asking you what to load the file as. Select everything I did.

Now wait for IDA to load your file.

7. Once IDA has finished loading your file, click at the very beginning of it and click Edit>Begin Selection. Scroll down to the very bottom and click on the last line so it highlights the whole thing. Click Edit>Code. Click Analyze, then yes. Wait for it to finish; this might take a while.

8. Now your file is ready to edit. Click Search>Text, then enter the dvar you want to edit. I will be using perk_killstreakreduction (Hardline). Once it finds it, it should look like this:

Look at the line under the dvar. See the "%r4, 1"? That is our default value for the dvar. Highlight the "1". Then switch to Hex View-A:

You can see that it has "38 80 00 01" highlighted. The "00 01" is what the dvar value is. Now on to how to change the dvar.

9. In the bottom left corner of the IDA Hex view, there should be an offset:

Remember in the beginning where you minimized HxD? Now open it up again. Hit Ctrl+G and enter the offset from IDA:

Now you will be at the offset from IDA. Highlight the next 4 bytes:

The "01" is the default value for our dvar. To modify hardline so you get all your killstreaks in 1 kill, you need to make it 11. So what you need to do is open Calculator, click Dec, enter 11, and click hex. 11 in hex is B. Overwrite "01" with "0B":

Save your EBOOT in HxD, close it and close down IDA.

10. Open PS3FOXX again. Go to step 3. Select your out_eboot.elf that you edited in Hx

For the Game ID, put "UP0002-BLUS30591-YOURNAME-" (replace UP0002-BLUS30591 with EP0002-<your region code> if not US). For name, put EBOOT.BIN. Click "Build Make Self NPDRM".

11. Go into the PS3FOXX folder. There will be a new folder that starts with "MAKE_SELF_NPRDM". Go inside it. There is your ready-to-test EBOOT.BIN








That's it guys, if you have any questions feel free to quote me and I'll try to get back to you.

ENJOY =D

^^^^^^^^^^^^^^^^^^^^^^^

so does max know how to blind it?
and would you get band just because that u altered the coding or because ppl are reporting u?

Just what I was looking for.....Thanks a mil bro



EDIT: quick question at the very end when building the eboot at the very end it makes a folder but there is nothing in it, PS3FOXX has some msg in the body but I can't read it. Any ideas of what I might have done wrong bro?


Here the error msg:
... An error occurred:
generation EBOOT.BIN failed please check the path of your file does not contain special characters

I know how to bind the eboot & nice tut

@ D3ss3rtPr0ducts F off with your Groaned shit ..

I learned how to do what i said on my own no tut !
Am i supposed to Feel intimidated by you ?
I find it funny that you thanked for this.
It shows you didn't put any time or research in to figuring out how to do this without a tutorial !
