Super Mario Bros. 3 (NES - Nintendo - 1988 - FAH)

This might be the best NES game, according to everyone but me. Don’t get me wrong, I love SMB3, but I’m more a Super Mario World kind of guy. I remember playing this game at friend’s home and having a good time, but I was always bothered by the 2 players mode in which you couldn’t play at the same time. Anyway, like SMB2, I don’t have the instruction manual for it, and I have to get it. Any tips for a FAH version of it?
