List of Super Mario Bros. pre-release and unused content
This is a list of pre-release and unused content for the game Super Mario Bros..
Early iteration
The development of Super Mario Bros. began with a 16x32 pixel square used as a placeholder, which couldn't jump at all and moved about a single screen. After taking notice of the sales figures for Mario Bros., Tezuka proposed the idea of using Mario for the game to Miyamoto, which was accepted.[1] Visible checkpoints were considered in development.Template:Refneeded
The game was initially far more focused on shooting than platforming. Mario could carry weapons (with a rifle and a "beam gun" mentioned as being usable),[2] and the control scheme was different; the up arrow of the 
was used to jump, while pressing 
used whatever item Mario carried or kicked when empty-handed[2].
The game was initially divided between ground and sky segments, which had Mario riding a rocket (or a cloud in later stages of development) and shooting enemies [2]. The sky-based bonus round of the final game are apparently a remnant of this idea[3].
The development sketches included in Super Mario All-Stars Limited Edition show that the game initially had screen-by-screen scrolling (similar to the later-released Super Mario Bros. Special) rather than continous scrolling as in the final version[4].
