I like to play some old console games from time to time on my PC. It all started when I wanted to play my favourite game from childhood - Pokemon Yellow for GameBoy / GameBoy Color. I didn't have GameBoy anymore so I downloaded http://www.emulator-zone.com/doc.php/gba/vboyadvance.html
I often look for emulators of really old consoles and play really old, classic games. However I saw there are emulators for rather new consoles, like PS2: http://www.emulator-zone.com/doc.php/ps2/pcsx2.html or even XBOX 360: http://xbx360.com. The newer is a console that emulator emulate, the more powerful PC you need to run it though.
Do you like emulators? Which emulators do you use?
