me dobleposteo actualizando:

In summary it seems that JB2 is nothing special at all. What they seem to be doing is using something called a DEBUG EBOOT which is burned onto a disc, and is playable on the PS3. So all we technically need is the debug eboot’s for each game which can be acquired via dev network (and people can get this via debug PS3′s).  So until Sony takes a stand against these debug eboots, the scene may have found their access to newer games.

parece que el JB2 es sólo para ganar pasta y lo que realmente se hace es usar un deug eboot, cuando tenga más info de como lanzar cualquier juego os iré comentando, si alguien ve algo que lo suba también
