actually the black carts are just unlicensed titles I have a few of them, none have the logo. But who knows look it up maybe it is... I also have a gold cart title 4 Quattro Sports with four games in one and you have to flip a little switch to play them. Its not rare tho ;( haha I love gold carts anyway... I am just starting to look for rare games now that Ive gotten all the carts I wanted. Starting with Dragon Warrior carts. Might get some repros some day because Im sure as hell not looking to spends hundreds on any one cart. I have a few hard to find ones but nothing really rare. Did get my first NES top loader which is kind of rare and awesome!
