This was the first portable Famiclone to have it's own built in screen, the other two being Redant's Game Axe and the Game Theory Admiral. Eats six D batteries in like an hour. Came out in around 87 or 88, so it's no surprise. Has a controller port for second player and can be hooked up to a TV like a normal console. Very, very, very rare. I have never seen one up for auction anywhere.
