A Sony patent has surfaced suggesting that PS1, PS2 and PS3 games could be emulated via the cloud. First posted to Twitter by user Renka_schedule, the tweet can be translated into English, at which point it reads "A large number of game titles across PS1/PS2/PS3 and various generations of game consoles can be stored and used via the cloud gaming library." "These games can be run on a virtual machine that mimics the operating system associated with each game console" it continues. The accompanying image shows drawings of the PlayStation 1,2 and 3 being emulated onto separate screens.
