Favorite games on emulators.

I've recently been using pcsx2 ( since it now supports more than two cores) and Dolphin to play some of my older games on my pc. Xenoblade, Persona 4 and FF10-2 look excellent. I was blown away by the difference. So what's some games you guys have played and are your favorites? Best looking? (I'm a sucker for pretty graphics added to my favorite games). Screenshots?
