I've been steadily following the progress of the jailbreak community since 3.55 where being on 3.55 kmeaw and wanting psn, I updated.
I was thinking around lately at how my old ps3 games have no problem playing on my ofw 4.00 and ofw 4.31 ps3s.
Since we have access to the private keys of 3.55 and we know that the ps3 will still accept GAMES signed with 3.55 private keys, can't we simple sign a GAME with 3.55 and once it's executed, shouldn't we be able to execute code that way?

I've looked around and no body seems to be trying game exploits, with 3.55 we can do this and the ps3 will accept, or else all games dating from before 3.55 would become unplayable.

and how exactly would you install that game?
burning it wouldnt work as the BD isnt hacked

Hypervisor/supervisor blocks game exploits.

Plus the fact the calculated keys aren't worth sh!t on 3.55+ fws.

What I mean is that you could possibly with the new lvo and the 3.55 keys create a game copying how original games are made. The ps3 would then load the game as a real game... Even though the BD is not hacked, in theory we should be able to bypass by signing it with 3.55 keys like other games released before the 3.56 update.

The keys are still usefull. They would allow us to simulate a real game. Having the game encrypted and signed like any other original pre 3.56 game, the ps3 should still accept it. Now, having been accepted by the ps3, we can attempt (I don't know how) to exploit hypervisor even though it blocks game exploits.

I think that @japsander means that without the BD being hacked we just cannot play these burned discs

Isn't there a file hash checklist? Then you can't even change the eboots.

No! you would need to find an exploit on cfw 4.31 signed with 3.55 keys and after you find an good exploit try it on ofw phat, recomended slim.Note, you would need an exploit on a higher layer lv1 would be enought for now, as it would unlock lv2...

We do not have the Private games to Resign Games for 3.60+ We have the Public keys for decrypting and the 3.55 private for re-encrypting on 3.55 But the 3.55 keys we have are black listed so we cannot do anything.

So if i get it right, the 3.55 keys we have right now have no games signed with them?

I understand what people are saying, like i said, I have been following closely on releases and I understand to some level the coding as well.
I am not proposing we break the security of the blue ray, I believe we can pass through it entirely.

If truly no game has ever been signed with the private keys we currently have, then I rest my case this is useless.

On the other hand, games were signed with the keys we have.
Also, a hash checklist doesn't exist.
To prove this, if a ps3 is never connected in anyway to the psn, it has the latest update, and a new game comes out which does not require a new update, the ps3 has to accept it. Games have to be checked in another manner.

how?
the drive firmware will not boot a burned disc (originals are pressed)
no amount of signing a file will convert a burned disc into a pressed one

for what you want to do would require a custom drive firmware (similar to xbox drive flashing)
even the optical disc emulator treats games as unmodified and will not handle custom code

by all means, try burning a bluray with a game (even a pre 3.55 one) and see if it will boot on OFW (even 3.55)
