Famicom-in-a-controller similar to all those Power Player machines, except this one also has the light gun built in. Very compact, cart slot on the bottom, some of them have games built inside.
I've got a unit similar to this and I've got to say that it's not bad. Made out of cheap stuff (as all pirate junk is) but can take a beating from the kids without falling apart to easily. Controls are fucntional and the buttons have good resistance to them. Works with standard Asian/Japanese Famicom carts, and usually can be found in discount stores for about $20.
