This is Mysterium, an Official/genuine game for the Nintendo GameBoy.

This game comes as CARTRIDGE ONLY.

This game is in good condition as pictured but the label does have a small amount of peeling in 2 corners and the cart has some browning as shown. It has been tested and it is in full working order.

This is an American NTSC game but the GameBoy is region free so it will work with any GameBoy console.

This is an official game that has the 2 digits indented into the label and a glossy Nintendo logo to show its authenticity.
