it's worth noting that for titles to be compatible with this kind of service, an x86 version must exist in some form in order to be run virtualised on their giant server farms. they aren't chain linking PS2s and hooking them up to the phone socket.
going from that to a local PS4 version is a relatively small step and the only reason you're not going to get them is business.
