Nope, absolutely no way. Only the earlier FAT models could do that
Thats not at ALL true! Have you seen the cobra USB dongle? if you are jailbroken and have this device you can use multiman to play your PS2 titles with software based emulation (since this is software based it will not support all titles. in BC models it enables full hardware backup support (Will play any PS2 title)
However if you use it you will soon realize why Sony disabled it as pure software emulation hardly works. Very few games will run very well and even for those handful that do you can't use a wireless controller (have to be plugged in by USB).
