It's pretty easy to do! I've had one for a while, but I just now got to sit down and play with it for a bit. The RetroPie script makes things very simple, though you'll probably want to play with overclock settings for best performance. The biggest surprise for me was getting PSX games working decently.

I have a second one and I just recently picked up the Adafruit LCD kit for the Pi, so I'm hoping to have some more fun with that soon.

I wonder how much you could overclock the Pi if you had some proper air cooling in it. Probably a fair amount, considering it works totally off passive cooling by default.
