Within the game's data are unused graphics for a message with a heart and text reading "アホ!", Japanese for "Idiot!" Of note is that while other unused graphics in the game are recycled from previous releases of Super Mario Bros., this message is exclusive to the All Night Nippon edition.

A special edition of Super Mario Bros.: The Lost Levels, entitled "All Night Nippon Super Mario Bros." was released only in Japan. It featured almost identical gameplay to that game and lifted level designs from Super Mario Bros., but instead replaced the enemies with Japanese celebrities. It was based on the popular Japanese radio program, "All Night Nippon", and was given away as a raffle prize from the program itself.
