Mario Bros. have returned

Return of Mario Bros., or sometimes Mario Bros. Returns, is a Japanese game for the Famicom Disk System. It is basically an updated version of Mario Bros.

Some new features:

• Some new levels were added.
• Mario and Luigi can now change direction in mid-air (much like modern remakes).
• The graphics and music were improved somewhat.
• High scores can now be saved.
• Advertisements appeared in between levels. Some were for upcoming Mario games, such as Super Mario Bros. 3. Others were for the Japanese food company Nagatanien, sponsor of this game.
• More game modes were added.
