The team behind RPCS3, a well-known PlayStation 3 emulator, has issued a warning about fraudulent emulators claiming to run PS3 games on mobile devices. These “scam” emulators are misleading users into believing that they can emulate PS3 games on Android or iOS platforms.
I believe RCPS3 uses a translation layer in order to achieve its accuracy, so I think porting it would be relatively easy. Then again, the last words of any programer are that something should be relatively easy.
