hey guys i spent nearly a month in sear4ch a ps2 emulator.
atlast i got epcsx2.
but the fact is that it is still in developing stage &
if u get it then finding bios will b a problem
if u get somehow bios then ryunning it in ur pc will b a problem bcoz ps2 require heavy hardware acceleration of about 3.24 ghz.which is not possible 4 many of us.
also creator of tis emulator says they r just successful in booting bios & running a little bit just a little of demo ps2 game.never a fullfledge game is run on it.
ps2 emulator needs to go along way still when ps 3 is going to b released.
best solution is go & buy yourselves a ps2
