They did overhaul the controller mapping in this update, along with just about everything else, so it would be worth checking out. I really can’t emphasize enough how massive this update is, it’s like the emulator leaping from 2010 to 2024, they’ve been exceptionally active over the past 4 years.
Aren’t there emulators for newer platforms out there now?
And of course. I assume you’re referring to RPCS3 for PS3. PS4 is also in the early stages of being emulated, with simple games being playable.
