A few days we reported to you about Graf_Chokolo working on SELF/SPRX decryption, today he has just released his PSGroove port which allows you to decrypt a SELF files and send the data VIA ethernet to your PC!
To quote:
Guys, i promised to you to make my SELF decrypter public. I just uploaded it
Let me first explain how it works.
I used only HV calls in my code because i wanted to learn how to decrypt SELFs without GameOS. The decryption and decompression of SELFs is done by isolated module appldr which is prepared and loaded by lv1_undocumented_function_99. After appldr is loaded it sends a message and waits for your instructions to decrypt some encrypted segments. When the message arrives i pass encrypted segment data to appldr through shared memory and it decrypts the passed data. When the decryption is done the payload sends the decrypted data over network to my PC and i capture it with tcpdump
I’m using IDA to analyze the decrypted code. First i extract the decrypted segments from pcap dump and load them at right addresses into IDA. I created a shell script to make segment extraction from pcap dumps easier. Virtual addresses of decrypted segments you will find in ELF header.
The target group of this release are again advanced programers among you. The goal of this release is not to give you a tool for SELF decryption but to show you how it can be done
My SELF decrypter is not able to decrypt games and NPDRMs yet but i’m working on it
I will document my findings about SELF decryption on my HV page in the next days.
Download the payload @ his Github page HERE.

Man I'm sure happy you guys are on our side.
If SONY had hackers like you we would be screwed.

Nice work, I am amazed at the progress this scene has shown. Even with ynos employees on all these sites telling everyone that jailbreaking will never happen. Way to stay focused. Thank you scene, you have been very good to us.

3 Things, I would like to see happen:
(1) GET BACK ONLINE!!!!!!!
(2) PS2, N64, Wii emulator
(3) MKV Support
Come on, Hackers! We know you can do it! Keep up the good work!

SELF unpacker is one of the biggest achievements to the PS3 scene since the JTAG itself, it’s the first step to decipher and the first step to set the PS3 free from its current nazi-like dictatorship.
most movies take 1-5 mins to transcode.
Unless you are aiming for full MKV support with editing capabilities there is no need for MKV support just to play pirated material.

all my movies are MKV too.
i wait it also.
and stop tell ****, all mkv are not pirated, like i transform all my DVDs to mkv..
we need a good player like vlc

Just convert MKV to M2TS. Sorted.

stupid idea...
anyways, this payload is a good new

Hmmmm any way someone can explain this to me, what does this mean to the community? How will it help other hackers?

Choose: High-Profile
Audio: 6-channel discrete to make it work on PS3
Handbrake makes output as x264 encoding in an m4v file.
The only reason to make use of MKV is if full theora/mkv implementation is made for video composing and editing is implemented, why ask for a player for a production format? Besides transcoding to m4v or m2ts or vob is ultra fast 1-5 mins depending on clumsyness of mkv file.
VLC? XBMC/Plex( MacOS X port of XBMC with iPad/iPhone remote app ) and MPlayer are alot better in my opinion.
