SACD saviour:
"Let me tell you guys where I am right now.. The current status is
that I can finally raw read SACDs from GameOS. Surprisingly this was
the biggest hurdle until now (got this working last week!!), it turned
out I had to re-authenticate the drive in order to allow disc access.
But these functions (two lines of code) were hidden very deep in the
shell and seemed completely unrelated to disc access :(, but I found
them :)..
So reading and writing is finally working:
http://code.google.com/p/sacd-ripper/source/browse/trunk/sacdread/sacd_lv2_storage.c
Another thing I've been reversing is the communication with the
SacModule (the module that authenticates the drive in order to decrypt
the SACD, and also deals with the decryption of the revocation table
(if the disc has one)):
http://code.google.com/p/sacd-ripper/source/browse/trunk/sacdread/sac_accessor.c
So at this point authentication seems to work, and the decryption
process starts without errors. But... the "decrypted" data is wrong
(problem occured yesterday, so still, very fresh..). In other words
the drive is "decrypting" the data, but the key that the drive is
using seems to be wrong.. so that's going to be the last hurdle.. and
I hope that's not going to take the amount of time that I had to spend
on drive authentication..!"
looking promising. hope you are all going well in your lives.
Also...once the cracking is completed, then the SACD-R side, of
getting all our players' firmware modified to play SACD-Rs, should
follow suit. I know who will help with all that, he's part of this old
'team' that I always referred to.
