This is a lot of NES games and the console to play them.  I got these from a friend who no longer wants them and immediately decided to sell it.  To my knowledge, the console works.

The games are:

Super Mario Bros / Duck Hunt (X2)

Super Mario Bros 3

Yoshi

Top Gun the Second Mission

Tetris

California Games

Back to the Future

Burger time

Anticipation

There are 2 power bricks and an RF Switch included.  Everything you'd ever need (to play Nintendo)
