graf_chokolo, l'homme qui casse les protections de la PS3 un peu plus chaque jour, nous à sorti aujourd'hui un payload qui permet de décrypter le LV2 de la PS3. Pour le commun des mortels, ça n'est pas utile directement, mais pour les autres, le LV2 ou kernel ou "GameOS" contrôle le lancement des jeux, et autre protections de la PS3.Le decrypter permet ainsi de le décompiler et comprendre comment il fonctionne, pour le modifier par exemple.
Je ne traduit pas son message vu qu'il ne concerne que les développeurs, qui doivent sûrement déjà comprendre l'anglais.
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!
