[E3-hacking] PBL V5.1

[Otaku]

Hi All..
JOOI, is there a list of currently known facts about the 5.1 PBL ?
I'd hate to just re-iterate what is already know.
Starter for 10 :

1) the blockcheck algorithm has changed - its no longer a simple 
bytewise add.
2) Another 2 pbl commands have been added.
3) there is now an sha256 implementation. ( Although this appears to 
only operate on a supplied buffer via one of the new commands, or on a 
modem download sequence ).

Missed anything ?
