We previously reported, that graf_chokolo was successful in decrypting lv2_kernel.self and other files. Today, he has released this payload to the public, so they can also decrypt these files.

I just release my lv2 kernel decrypter.

You need metldr, lv2ldr, RL_FOR_PROGRAM.img and lv2_kernel.self.
You have first to dump your metldr from FLASH memory.

lv2ldr you will find also in your FLASH memory or in decrypted CORE_OS_PACKAGE.pkg from PUP files.
RL_FOR_PROGRAM.img is a revoke list for programs and can be also found in PUP files.
lv2_kernel.self is on your FLASH memory or in decrypted CORE_OS_PACKAGE.pkg.

First I send all files to PS3 and store them in memory. After that i load metldr in isolation mode and pass it the address of lv2ldr. The code is very low level and many things are done by directly manipulating SPU registers

If you have any questions or problems then feel free to contact me or ask here. I will try to help you.
I will try to document my findings on my homepage.

I also uploaded a code which can communicate with USB Dongle Authenticator by using Dispatcher Manager without using any GameOS functions It’s exactly what GameOS does, just low level.

Have fun guys!

Guys, just to make sure that you know :-) LV2 decrypter is also PS2 emu decrypter, just change LPAR auth id in code :-) PS2 emu is like GameOS, it’s LV2 and is decrypted by lv2ldr :-)

graf_chokolo is probobly one of the most generous hackers out there, releasing finding to help other developer and hackers to reach their goal. unlike others who dont like to share with others to help other devs out. i really think that if everyone worked together they would be able to smoke sony lol. if they put all findings together i bet theyd be able to create cfw. i bet some hackers already have cfw, just dont wanna release so they dont have to worry about sony.

Haha smash is unreal. A full fps emulator of super smash or brawl would be the best

really? because i mean there's that "box head" like game
i mean all brawl is manipulating bones with numbers, im not thinking of a complete port but maybe model uses? for mini games and maybe eventually a full version of brawl
unless dolphin will be perfect lol
