I'm pretty sure it's fake, like all PS3 and 360 emulators have been so far. I mean emulating a PowerPC 970 CPU that smoothly using currently available PC hardware? We've barely gotten to the stage where we can emulate a PS2 with the hardware we have now. Also, why don't they have a homepage or any kind of website for this claimed emulator, just a random fishy download link? That game footage could also be just as well captured from the PC version, just edited to run in a overlay of a mockup program. Not convinced.
I'll be glad if I'm proved wrong, but I'm sceptical as hell about this.
