The FC twin does exactly what it is supposed to do. It plays both SNES and NES cartridges. It comes with two controllers that are exact replicas of original super nintendo controllers.

It isn't bad playing NES with the snes controller, it actually works really good. you can't plug in the light gun into the FC twin either. The controllers can also be plugged in to the original SNES which is good since mine are broken.

The only complaint that i have is that it is a task getting NES games out of the system. Besides this, the FC twin is a great buy.
