Great computure programme that can play all the classic console game system games from: snes, nes, atari.ect.But it costs you money to get an emulator.(the best thing to do is get a burned version from a friend who has already got one, like I did, lol) It also slows your computure right down. But its great fun. You can change the colours of the games you play. You can play the games with a special controler. You can also get weird versionnof games, like sonario which is a sega sonic game with mario as sonic. It's so cool. The roms are illegal but who cares, no one is gonna care.
