Race Car Handheld

This is a Odd little handheld i pick up on e-bay a couple of years back. When i saw it and that it was going for about 5 USD, i just couldn't help my self. It works as a pull back race car and a handheld game. The games are sort of cool having the screens right on the cartridges. I have no information on who makes this handheld as it has no stamping or labels. The 5 it came with are : Baseball Challenge First , Sky Battle , The King Of Fighters , Championship on The Sea , and Race No.1
