if you have CFW PS3
gaf
So over the last week or so the file encryption on the PS2 classics emulator has been completely reverse-engineered. You can now switch the ISO of any PS2 classic with that of any other PS2 game if you have a PS3 with CFW. Compatibility should be pretty high.
Here is some pics of Persona 4 running on my PS3 slim I just took:

No audio/video glitches, runs fullspeed.
Process is a little complex atm. I expect this to be mind-numbingly simple within a week though.
FFX apparently works fine too.
