Toe, I saw this device in a mall that was built into an old N64 controller, and it has several thousand NES, old arcade, and Genesis games. The game also has a lightgun that can plug into it to play the shooting games.
It cost $50, and although I question some unheard of company making crappy-looking toys they sell in mall booths, it looked really cool.
They also were selling shitty replicas of DDR, as well as a tennis game with a wireless racket and a boxing game with wireless gloves, and all of them sucked really really bad.
So I question wether the 8bit Gamepack is good or bad.
