Awesome article! I was looking into BB 4 Friends yesterday wondering if it were worth it. I'm fairly certain the FM Towns game was not exclusive to the Marty though, as the article states. Just a very minor note.
Kurt, "Taito decided to add a simple four-letter password system that updates as the players progress." -> The NES password system is 5 letters. I have the super bubble bobble code memorized as BBAJI, so I know it's definitely 5 letters.
