The US version, it plays US cartridges...

I haven't tried the gun with it, which I own, but the standard NES controller worked.

It was at a 2nd hand store for $19.99, "used" but everything was still wrapped up, the box wasn't shrink wrapped though...

I played Super Mario 3 and Tiger Heli on it, which was cool.

The thing weighed less than 1 lb.
