All Night Nippon: Super Mario Bros.

All Night Nippon Super Mario Bros. is an officially licensed Super Mario Bros. clone, in that the gameplay is the same, but some of the enemies are replaced with rock stars from the Japanese show All Night Nippon. Also, some levels are taken from Super Mario Bros. 2 and Vs. Super Mario Bros. The game was a raffle prize from the All Night Nippon radio station, and ran on the Famicom Disk System. It also had other graphic changes, such as the clouds with smiley faces, and the ground which, in the game, is rocky instead of brick pathed.
