Thanks to the great developers of nrnoksnes, we have now snes running on n900 fullscreen. Wiimote supported, as well as tv out.
take a look at the video:
[Edit] I ported wiicontrol on the weekend just to get this awesomness up and running. While it's great that you can play games on the go and to be able to continue later from your couch with wiimote, you can also just bring your wiimote with you and use that to play games. It's just perfect.
And kids, don't pirate games.
