This version introduced a difficulty setting and became a staple in later console releases, contributing to the franchise's popularity and legacy.
The first port of Mario Bros. was developed by Nintendo for the Famicom and later released in American under the Arcade Classics series. It follows most of the features of the arcade game, and adds a difficulty setting.
This version would be the most re-released version in future consoles.
