NESTOPIA !!!!!!!!

A friend showed me this recently..as some of u may know, Nestopia is a client u can download in order to play really old games of a file called .nes (nintendo's NES systems).
u can find in various game-sites those files which contain the code of the old game.
open it with the window of NESTOPIA and play!
