Emulation

What are your favourite games to relive your nostalgia on what emulator? I used to play the hell out of Monkeyball on gamecube so I enjoy using Dolphin for that or Mario Sunshine.

Emulation has given me a wide backlog of great titles to play in the midst of "AAA" sludge.

What's your impression on emulation? What is your favourite thing about it?

Cheers!
