What are some sick 16-bit Co-op games?

Oh my G-d I forgot Contra III: The Alien Wars for SNES! Luckily these other homies had my back. Onyxmeth is nuts if he doesn't think there was good co-op back in the day. Try out all the games I listed. There's definitely something for you in there. Good luck.

I forgot about Contra too, and smacked myself upside the head for it, but there's a lot of games there that I don't feel have aged as well as nostalgia remembers it. I just think the multiplayer aspects of these consoles in player vs. player trumps most of the co-op offerings. Just trying to paint a picture that he may have more fun on his trip playing against each other as opposed to with each other.
