You don't PS3 must connect with WiFi or Ethernet only not USB dial up or mobile devices

NO you can not. A PC Emulator includes a PS2 Bios so it could not be called solely on a computer. Not that I know if you can use it to get on the Playstation Network. Any PC can access the Playstation network that is available for the PC and it is not the online games section that is available, but the support section. A PC could not even play a PS3 game and the Playstation Network would not work with a PC game as they are not compatible.
