This was the poor man's NES/ SMS.
I felt really bad for my mate who got one of these the same Christmas I got my SMS. It wasn't really much more than a souped up 2600 and had nothing that made me say "I want one of those".
It had these horrible control pads with little joysticks attached to them which broke easily. First system to have backward compatibility and was once described as just a sexier way to play your 2600 games. With a delay of 2 years in its release it never really stood a chance with the NES and SMS.
