I like the idea but the controllers don't work very well. One doesn't go to the left, so in a two-player game we need to connect a good controller every time. Depending on the game and your needs, you're in a fix. In Contra, one controller doesn't go left (or back) and the other doesn't crouch, so it will easily kill you. There is a lag in the controller movements and you have to hit the reset button every time you want to change the game. As much nostalgia as it caused, I'm too disappointed in the controllers and will be back. I hope I find something that works.
