It’s one of the rarest video game cartridges in existence. Earth Bound (Mother) was fully ready for release on the Nintendo Entertainment System in 1990, but only got as far as a handful of prototypes. Roo has acquired one of these rare carts and is going in depth to give you all the info he can on it.

Where do each of the carts that have escaped Nintendo of America live now? What’s on the circuit board? What does a play through look like? All this and more brought to you courtesy of the Clan of the Gray Wolf.
