I currently own a PS3 slim 500GB with 4.25 version. I've been looking at the net for such cracks which allow me to play downloaded games on PS3's hard disk. I am not sure where can i look for in the forum? Does a firmware which allow me to do that exist right now? Someone please advise me! If there is, how can i go about installing the firmware onto my PS3? Is it safe? What is the proper procedure. Many thanks!!!
