2.00 hasn't been "hacked" yet, the only thing they did was find an exploit using basic MIPS binary coding. Some sort of user shell still must be created in order to play homebrew.

(I am following the psp scene because I upgraded to 2.00 by accident :icon33:)

Isn't that just a matter of carrying over the shell used for previous version and making some minor changes?

It's not really about the shell per-see. Most if not all of the apps that previously ran on 1.5 will have to have updated bits of code in order to launch.

It gives good hope for me. Seems that I won't have to wait as long as I thought I would for some classic game emulators

Yep... lol

The current firmware will never truely be hacked anyways, it uses AES 128-bit encryption, so any homebrew will be done mickey mouse through exploits.

One thing I don't understand... how can it use encryption if the player itself needs to use it?

What I mean is.. if it's encrypted, yet it works on your PSP,then you must have both the encrypted data and the key for that data.

I thought keys were only good for privacy assuming noone found them, excepting a public/private key infrastructure.

Exactly, any game sony puts out is signed with a special key, and only sony can sign key codes to the game / firmware updates. There are ~3 checkpoints that the psp uses to be able to use software

1 - Simple version check
2 - md5 checksum compare
3 - AES Key (Signed code)

The people hacing psp all get past step 2, but once at step 3 thats it, there is no way to brute force AES128, as with one PC, it would take around 11 million years lol.
