Like what part of the FW? The
PS3 uses 2 sets of keys to identify the disc, one for decryption (can be changed) and one for encryption (can't be changed), the latter one is the one they are using, it friggin emulates the whole drive. So BR disc->(decryption)->BR-drive->
(encryption)->
PS3, They can't hop from BD disc to
PS3, it has to go through that encryoption process, and that is what they know, and it can't be changed.
If you ask me the keys have been found in a while but devs wanna make some money out of it, I'm no dev but I've been here long enough to understand certain things. I also might be wrong, but if I would be and if 3k3y were lying then the devs in the scene would've said that when it was announced.
EDIT
According to them the 3k3y will cost 129$ w/o shipping. I paid 110e (about 150$) for a ps3break dongle, but the dongle era is gone, and I hope it won't ever come back.
