I doubt this will run well on anything but the latest high base clock PC's. I have a 2.2 Ghz Sandy Bridge laptop, with Turbo Boost up to 3.1 Ghz, but Turbo Boost is mainly marketing scam by Intel, so it will run as if it's 2.2 Ghz. Plus Haswell only has a ~15 percent IPC improvement over SNB. With the PS2 emulator I can't even get 60 fps for most games.

Does it matter though, this is an elegant hack in the true sense of the word.

The cell processors architecture pretty much rules out high fidelity emulation directly on an x86 chip any time soon.

Not all hacks have to be useful (even for a given value of useful).

As it stands right now the chance of seeing a playable PS3 emulator is much less than the chance of seeing a playable PS4 emulator. This is of course due to the x86 processor on PS4

EDIT: DCKing corrected me on this I erroneously assumed that the CPU architecture was the main hurdle. Turns out the GPU is a much bigger problem. The more you know, thanks DCKing.

It won't run well, period. It's very early stages and isn't even handling textures properly, let alone running games smoothly.

This is not true. The great complexity of modern GPUs is a much larger problem generally than emulating a CPU. Furthermore, the previous x86-equipped console, the original Xbox, never saw any decent progress in emulation whereas its far more exotic competitors have really good emulators.

That's not to say the exotic Cell architecture is not a major problem for PS3 emulation. It is. But having an x86 CPU does not seem to increase the emulatability of a console at all.

Do you think this is because of difficulty in emulation or because the X-Box was so easy to hack? It was not super expensive to buy a used X-Box and mod it even back when new games were coming out for it, so maybe it just didn't seem like a worthwhile investment to spend time writing an emulator?
