79w ago - Following up on his previous updates, this weekend PlayStation 3 developer Heden of DeLiGhT has made available the source code for his PS3 SELF / SPRX Decrypter v0.6 BETA homebrew application below.
158w ago - A few days back graf_chokoloreleased a PS3 SELF Decrypter PSGroove payload, and today Heden of DeLiGhT has released at PSGroove (linked above) a PlayStation 3 SELF / SPRX Decrypter application followed by an update below.
To quote: Unlike graf_chokolo's method, DeLiGhT's application does not require a special payload to decrypt.
Simply place the SELF/SPRX you want decrypted into /dev_hdd0/game/DCRY00001/USRDIR/SOURCE/ Then run the SELF/SPRX DECRYPTER from the XMB, and finally retrieve the decrypted files from /dev_hdd0/game/DCRY00001/USRDIR/DESTINATION/
From the ReadMe File: SELF/SPRX DECRYPTER - V0.5 BETA
12/04/10 - V0.5B - Initial BETA Release
- Decrypting internal PS3's SELF/SPRX files
[BETA - The decrypter hangs on some files]
GameOS utilizes files to make the console work (I won't give details) These files (SELF = EXE, SPRX = DLL) are stored in /dev_flash. This tool enables to decrypt...
238w ago - Today xorloser has posted an update to his previous PS3 ELF/SELF/PRX/SPRX PPU Loader for IDA v5.2.
To quote: I've been busy digging into the PS3 lately, I decided it's finally time to see what secrets can be extracted from it. During my investigations I found that level-1 syscalls, a.k.a. hypercalls, are not handled by IDA so I decided to add support for it to the existing PPC Altivec plugin. Get the updated plugins and copy them to your "IDAplugins" directory to install them.
For those who don't know, level-1 syscalls are used to call hypervisor functions. On a PS3 the hypervisor is known as as "lv1″ (level1) since it is the lowest level that runs directly on top of the hardware.
The operating system is executed on top of this and is known as "lv2″ (level2). The two common operating systems are GameOS which PS3 games run on, and OtherOS which is usually used to run linux.
Since both OSes run on top of the same lv1 hypervisor, they use...
THIS DOES NOT DECRYPT ANY FILES !!!! That means that for now this loader will ONLY work on unencrypted files. There are a few such files "in the wild" that have been found on Sony update servers and such.
As well as loading the supported PS3 filetypes in both 32bit and 64bit vesions of IDA this also resolves and sets up all imports, exports and syscalls. It also only supports PS3 PPU files as the PS3 SPU CPU is not supported by IDA at this time.
