everything will be hacked sometimes
Sony thought it had found the answer. New UMD format for games for its players. No UMD writers nor blanco UMD available. Just put up the money for the games.
but just as with DVD, where the region-controls are now easily bypassed or ipodfiles where the limits are hacked, reset and rehacked again, it wasn't long before there was a solution. They are using a memorystick or are now trying to empty old UMD's to download new games to them.
