The 7800 got the same style of Choplifter that the 5200 and 8-bits received…only on steroids. The graphics have been beefed up. The joystick controls could have used more attention but are effective and work. Trying to land on the landing pad can be a bit of a pain as the helicopter tends to lag at responding to joystick movement.

The only version of Choplifter I can remember playing was on the Commodore 64. It looks like the Atari 7800 has more colors and more detail in general. To be fair though, i think the Commodore 64 version was released very early in the Commodore 64’s life and was pretty much a straight port of the original Apple 2 version. It was reasonably fun to play though.
