Bought this from Ebay for about £10 used.
Its based on the original Sega Megadrive game, Outrun 2019 but is built into a little console you plug into your TV using RCA cables.
The main console plugs in to the TV, is powered batteries and has a wire attached to a handheld gamepad that looks a little like a racing wheel. You hold it in your hand and the wheel sort of slides up and down to move the racing car left and right. There are some other buttons for additional functions like turbo and accelerate. It uses original graphics and is quite good fun if you remember playing original Megadrive games.
Made by Radica in about 2004. This is a self-contained little Sega Genesis, Megadrive console running this one game. 25 courses and 5 different levels. Radica made a range of LCD and retro console games like this.
