I've recently been playing a fair bit of Kaettekita Mario Bros. on the FDS, and found out that when the game was released it was supported with a scoring competition. Basically, score 100,000 points and you get a code to mail in to be entered to win some Mario playing cards. Score 200,000 or more and you win a copy of Super Mario Bros. 3!
Found the details here:http://www.mariowiki.com/Kaettekita_Mario_Bros.
Obviously the contest is over now, but how cool would this have been as a kid? With limited money to buy more games, I would have trained all day long to reach the 200,000 point mark.
Have you played Kaettekita Mario Bros? If so, have you beaten the 200,000 point mark?
