hardcore retro gamin'
I ended up getting this cart myself as part of a bundle. It's definitely yellow.I don't have much to add to this batch of oddball games, except that City Connection is one of those not-especially-notable NES games which has grown on me. Part of it is because I love the Honda City Turbo, but part of it is just because I love the banana-yellow FC cart and the adorable artwork which is on both the FC and the NES versions.
One of the cool things is that it also looks like it has a mini-manual on the back of the cart. I'm not sure how common that was with Famicom carts, but it's really neat here.
