[NES] Super Mario Bros 3 - Card flipping + W3S7

Now these are the levels I started to get unfamiliar with. I think back then, we don't really have that much of time to play with the game. Those nintendo console tend to get heated up pretty badly if being played for hours straight. Not forgetting, back then my brother's best pal ride a bicycle to our house with the console and hook it up with our TV and 3 of us taking turn to play with it. And therefore, the two of them doesn't really like to share with me since I'm clumsy. You can see how clumsy Mario was in the game, that's how bad I am in controlling these stuff.
