A friend of mine found this site where you can play old nes games on your computer. You don’t have to do anything but having fun playing the game, no downloads, nothing… well, you need Java SE 6, but you probably already have that.

There are nearly 700 NES games including the legendary ones like Zelda and Kirby’s adventure, so you don’t have to be bored, if you are right now (you must be, otherwise you wouldn’t be reading this post).

Start playing at http://www.virtualnes.com/
A great site, especially if you’re nintendo fan =) (ofcourse, buying a NES and all the games is much more fun/better.. but this will do for the moment)

Playing Kirby’s adventure (great game!)
