PCSX2

It's the best PlayStation 2 emulator available.

o_O And, for the record, you can't ask about ISOs. However, yes.. that IS the best one out there. Still got some emulating issues, but ultimately pretty decent (you can actually play through games with it). ^^ Keep in mind that you need a pretty good PC to run it, though.
