OMFG! Didn't know it at all!! I sold him one tape 3 weeks ago, he was one of the first ones in purchasing it. but he's selling 4 units??? The one in the ebay pic is the original of mine, I don't understand how he manufactured the other 3 tapes :(
And the price: £20, that's more than double my price...
And what can I do, if the game is a "copy" of Nintendo's original?
Thanks a lot for the notice, @binaryrooster
