Hackers Bypass PSP Copy Protection
"It was never going to take very long, of course, but hackers have at last worked out how to bypass the copy protection scheme used by Sony to lock down content on the PlayStation Portable’s Universal Media Disc (UMD).
"Piracy doesn’t appear to be an issue yet, since there’s no way of copying games pulled from an official 1.8GB UMD onto a fresh disc, UMD being, for now, a read-only medium."
