A PSX-Scene member known as Graf_Chokolo, who brought you the full hypervisor details (read more about it here), today has released his version of the PSGroove payload that allows developers to finally see full details out of the PS3 system firmware complete with decrypted contents. This is obviously for the more technical and "hardcore" PS3 hackers out there, so if your an average end user, this is not for you.

To quote: So guys, i promised to you that i will made my PSGroove payload public. I just uploaded it to github. Let me first explain how it works. I do not have much free time, so please do not expect me to explain every detail to you :-) The target group of this release are advanced programmers among you. The source code is not commented but it?s clean, well structured and self-explaining.

My payload has 2 stages. The 1st stage is actually a PSGroove payload. It initializes the gelic device and allocates memory needed for the 2nd stage. Just compile the 1st stage binary, convert it to C hex array and replace the PSGroove payload.

The 2nd stage does the real job, e.g. decrypts a CORE_OS_PACKAGE.pkg from a PUP file, runs some isolated SPU module or dumps FLASH. The 2nd stage binary is sent to PS3 over Ethernet with ?sendfile? which i also provided. The 1st stage code receives this data and stores it in a memory region of size 64 kb. After the upload is complete, the 1st stage code jumps to the 2nd stage code and executes it. So, you have to program PSGroove only once and can just change the 2nd stage binary to execute different code.

In order to be able to run isolated SPUs, you first need to dump your FLASH memory. Then extract these files from dump and after that you can use it e.g. to decrypt packages :-) I described how to extract files from FLASH dump on my Hypervisor Reverse Engineering page.

To be able to decrypt packages from PUP file, first you need to extract a revoke list for packages from PUP file 3.41 e.g. (RL_FOR_PACKAGE.pkg). Just extract it, convert it to C hex array and paste it into rvk_pkg_341.c. You have to do it yourself because i don?t want any legal problems with SONY.

I didn?t use any GameOS functions in my code because my goal is to reverse Hypervisor and i wanted to learn how to do it without GameOS. I don?t plan to release any GameOS tools, so feel free to create new cool and helpful programs for GameOS using my code :-)

I?m using ppu toolchain for Linux provided by IBM to compile the source code.

I will try to answer any of your questions here. But please do not ask me questions like how to install ppu compiler or something like that :-) You will find everything on the Internet. I don?t have much time, so try to do as much as you can by yourself, you will benefit from it yourself :-)

So, have fun guys :-)

Dude, you guys shouldent bash on $ony, I know they did some fuked up things (take other OS away and going to be stealing personel info like pics and pesanel contents of any HDD atached to the ps3) buuut, you like the system, you like the games, they just dont want their system hacked and im sure they have people that read this crap and report back to $ony, and see all of this bitter trash talk and it makes them really want to smash the PS3 hacking "scene".

All I'm saying is if your going to say bad things over and over again keep on point, and dont just talk trash you sound stupid. We should be orginized with these complaints, to the point, what they did and why you dont like it. I dont mean to sound like a fag, but im just sick of seeing random stupid baligerant post against the best gaming system ever made.(in my opinion)

well said. i love the ps3 and sony for making it and putting out great games. i have had every playstation system except for the pspgo, seems like a waste. you can not blame them for trying to save their baby. they lost the war against the psp and are trying to do every thing they can to make sure it does not happen to the ps3. i hope sony is around forever to keep bringing us great electronics and video game systems. i think people are just saying bad things about them and saying fu because they think it is cool and they want to be apart of the crowd.

[XMuzzlerX]

Yeah, im glad your on the same page, and I hope more people think the same (logical) way as you!

This Is Great News... NIce Work I wonder If There Is a Way To Decrypt Retail .self Files With This Payload. I will Just Have to See. Thanks Again.

personally, i feel upset with SONY for many things, but I dont think they can ever do enough things wrong for me to not still love them for my PS2 years(which are still ongoing: just played timesplitters 2 and future perfect today :D)

Also this is a brilliant payload ill probably take a closer look at it tomorrow currently playing my backed up assassin's creed brotherhood
