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.
The PS3 has a really weird CPU/GPU design that makes it challenging to emulate with any reasonable performance. The same was true for the PS2, which is why a console that old still has to rely on hacks and workarounds to gain any decent performance even on desktop, but the PS3 is a good bit faster and a decent chunk weirder. It also has better copy protection, though I’m sure that has been cracked by now.
