Sony has confirmed with IGN what Joystiq and the Fanboy sites
discovered last night: current downloaded PlayStation Classic titles do not work on the PS3, despite its firmware upgrade
The problem is that two files -- the ROM and its certification key -- are needed for the PS One titles to work on the PSP
, but that "such a system is not needed on the PlayStation 3," according to the article. We're not sure how this explains the console's inability to play the titles, but rest assured SCEA manager Al de Leon told IGN that, "we'll be replacing the older PS1 games with fixed versions sometime in May" and you will then be able to download the games directly to your hard drive.
Sony did not comment on whether or not previously-disabled multiplayer modes would be reinstated upon the May update.
