I feel sorry for the guy who asked about a PS3 emulator for the PS4 Pro who got the below response and his thread locked 
The reality is there is a Linux distro running on PS4 called Psxitarch which actually has video evidence of it running (quite badly but still running) Cemu (Wii U emulator) and RPCS3 (PS3 emulator). It is currently on release v2 which has fixed sound output. It has working video drivers hardware accelerated.
I'm interested in seeing how it develops.
DinohScene said:Xbone and PS4 emulating a PS3 won't happen for a very very long time, if ever.
Please stop making stupid threads like this.
