Games Sony has responded to the recent cracking of the Playstation3, and the company claism that they can fix the issue - which ought to be impossible considering the scope of the hack. "We are aware of this, and are currently looking into it," Sony said, "We will fix the issues through network updates, but because this is a security issue, we are not able to provide you with any more details."

RE[5]: Multiple root keys?

Logistically it's not that hard for them, as the have all they already have checksums for every PS3 game in existence (they signed them afterall).

Not so sure as a checksum is like a bit parity in the sense that it does not suffice to reconstitute the data that has been pari... (err, is there a word for that action?) or checksummed.

You do checksum from data. Using a different checksum algorithm requires the original data, not just the few bytes that form the old checksum. So yes, it may be a logistical nightmare for Sony.
