Um...Magical Chase is a full retail product that was manufactured by the thousands. One sat on the shelf at my local EB for a year until it was bought back by the distributor.
Little known fact: the "magical" in Magical Chase does not mean its actually magical. It's just a TG16 game like any other.
This is (supposedly) a prototype piece of hardware that was never released, announced, or even shown to the public. Its exponentially more rare and valuable than MC (again, assuming its actually real).
