Since I´m probably never getting a NTSC ps2 compatible ps3, I might as well throw my lamebrain idea out here. it´s the only way I think the ps3 could be vunerable because of the ps2. It requires having an original ps2 game that can be installed onto the hdd. Since I can´t install any games on my PAL 60gb, I´m a bit ignorant of the process.
If anybody has info, pics, or videos that they would like to share of a ps2 game intalling on the ps3, I´m interested. If anyone has info of the HDD layout of a ps2 game that has been installed, I think that could be very interesting.
Ok, I´m not too familiar with the layout of the ps3 HDD but I know all games and demos have EBOOT files. so I´m assuming when you install any game(psx included). there´s always a signed EBOOT on the hdd and when you start the game from XMB your running the EBOOT, correct?
$ony has always provided us with signed eboots even for the psx games.
Now here´s my big question??
When you click on the icon in the XMB of a ps2game that has been installed are you initiating a EBOOT? my ps2games don´t have any eboots so did the ps3 build an EBOOT? a signed EBOOT? If that is the case would it be possible in any way, with a DEV console or Infectus, to sniff the info of the process. at best steal the key, lol, keep dreaming
But if it is creating a signed eboot maybe we could trick it into signing some homebrew code. make a backup of the disc to be installed, throw in a Hello World. open up the ps3 and do a quick disc swap with the original. Then with a miracle, when you go to start the ps2 game you installed from XMB, HELLOWORLD will magically pop up on the screen
Maybe a less amazing but more realistic option would be to make a backup of the ps2 game and switch the game elf with another one, like uLaunch.elf. doing a quick disc swap before installing. then instead of the game booting from XMB it would be uLaunch.elf, hopefully with hdd access. If not maybe usbloader. if you could boot it from XMB, it would be better than nothing.
Keep in mind I´m not saying any of this will work. these are just wild ideas but if anyone wants to discuss, please do. i´m always hoping to learn a little more myself.
