But, also still in early stage.
RPCS3 is a promising PlayStation 3 emulator, and is able to boot a few commercial games (like Disgaea 3).
Following the news of the 'Project Xenia' Xbox 360 emulator, we now have info about the progress of another last-gen emu, this time a PlayStation 3 one called 'RPCS3'.
Seems that the developers have been worked on it since 2011, but have recently shown that the emu is now able to boot a couple commercial games, like Disgaea 3 and Arkedo Series 02: Swap!.
Of course that this emu is still in early stages, and the games run slow/buggy, but it's a pretty awesome progress.
Here are some screens and videos:
Arkedo Series - 02 Swap! - VIDEO 1 (First commercial game to boot).
Arkedo Series - 02 Swap! - VIDEO 2 (BELOW!)
