Working Nintendo Game Boy. This is complete in the box with all inserts and the Legend of Zelda Link's Awakening game. The unique and rare thing is that this Game Boy has the complete Proof of Purchase card attached to the box and the serial numbers match the Game Boy console!

The Game Boy and the game do work, although there is slight pixelation on the left of the screen (see the last photo - the line in the middle is a reflection of light - the pixelation is on the far left of the screen). The battery compartment is clean, there are no scratches on the screen and the sound does work.
Please don't hesitate to ask questions!
