One of my favorite games.
I love Kid Icarus and Metroid. They are sister games. They were made at the same time using similar engines. They have similar passward systems (24 chars from 64). They draw their screens using the same engine. There are many platforms that look the same in both games. (In Norfair and world 3-Skyland)
Trivia: In Japan Metroid and Kid Icarus used save slots to save games. When they ported it to America they went to the password system.
I have cracked the password for Kid Icarus. :)
