PS3とBike

Update: One more update… And really, you should just go to geohot’s blog to see what’s up… He’s released some code for people to start playing with… Install OtherOS and have it.

Update: Geohot has shared a little status update concerning his PS3 hackjob… But first, know this: 1) Don’t expect any tool to be released by Geohot himself; 2) This hack does not work on the PS3 Slim; 3) The plan is to [hopefully] find and post the PS3 decryption keys so other hardcores can partake in the PS3 hacking fun. So thus far, here’s what’s up… To quote Geohot –

I have added two hypercalls, lv1_peek and lv1_poke. peek reads memory in real space(including all the MMIO), poke writes it. I can also add other arbitrary hypercalls as I see fit.

The hypervisor is complicated, it is written in C++ and is PPC, which I am not that familiar with yet.

Some people pointed out that I have not accessed the isolated SPEs. This is true. Although as far as doing anything with the system, it doesn’t matter. The PPE can’t read the isolated data, but it can kick the isolated SPEs out. Decrypt the PPE binary you need using the intact SPE and save the decrypted version. Kick out the SPE, and patch the decrypted version all you want. And interesting note, by the time you get to OtherOS, all 7 working SPEs are stopped.

Despite this, I am working on the isolated SPEs now(which I can now load).

Again, I suggest you keep your browser locked and loaded at Geohot’s PS3 blog. Much respect, George.
