Well I haven't tried it out myself, apparently this people found the new exploits on the new 6.2 Firmware for PSP. So...... Sony can't do much about it since it was a really old title and is available everywhere and coincidently is for 6.2. So..... If is real and they can make a new CFW for it then...... newest game including Kingdom Hearts and Metal Gear Solid would be playable. For some reason I feel this wouldn't lead to somewhere. Not sure why. Hope good news will come along soon.
