I've got a few:
1) In Super Smash Bros. Brawl, Peach's Peach Blossom theme is a sped up version of the Sky Land theme from Super Mario Bros. 3.
2) The Water Land theme from Super Mario Bros. 3 has a relation to the Fairy Fountain theme in later Zelda games from A Link to the Past onward.
3) In Mega Man X, X can find the secret Hadoken fireball and in Mega Man X2, X can get the Shoryuken.
4) Chun-Li has a cameo in Breath of Fire 1. While visiting Bleak, talk to the boy who thinks he is a magician. When he asks you to put coins on the table, agree to it. When he says ''Look behind you!'', say no twice and then yes once. After that, you should see Chun-Li practicing her Lightning Kick.
5) On the Super Game Boy, you can trigger the screensaver of your chosen border immediately by pushing L 4 times, R once, L 4 times, and R once.
