The PlayStation 4 is a console created by Sony.
As the successor to the PlayStation 3, the console features improved specifications and a more community based operating system.
As the PlayStation 4's file system has yet to be opened, there are currently no tools available for the PlayStation 4 to help ripping content. Currently, the scene is very hushed, so getting any content is almost impossible, unless you know the right people.
Currently there is only one genuine emulator for the PS4 and that is Orbital however it is at a very early state and mostly at the research stage. No games work and is not user friendly.
Do not expect working PS4 emulation for a good while and had it worked, no current available computer would be able to run it full speed.
