Hi. I've checked it. There's no difference using these settings and those available for any jailbroken PS3.
I've tried two games ( World Tour Soccer 2006 and Sensible Soccer 2006).
Both runs smoothly, but I got better results in PCSX 2 ( PC Windows ), due to many settings available. The hard side is to choose the correct ones and have a very good machine.
But this emulator it's the only decent way to play PS2 titles which aren't released for PS3 so far.
I hope something alike, will be possible with a improved built-in emulator on PS3.
Regards
