The Game Boy released on April 21, 1989 in Japan, followed by North America on July 31, 1989, and lastly in Europe on September 28, 1990. It is characterized by a large grey casing and model number DMG-01.
I recently picked up an original Gameboy. It was left in a barn for many years with the batteries in it. How do i get the corrosion off the circuit board.
