Picked up for $1 at a garage sale. Yes, I know it's a pirate/bootleg, but does it have any value? I'm not looking to sell it.

Here's a photo I found online of a nearly identical cart:

Mine differs slightly in that the embossing on mine just says GAME whereas the pictured one has GAME COLOR on it.
