Video used in Commercials
[<youtube align="right" width="256" height="240">fWax6C3KPNU</youtube>] A short piece of prerelease footage is featured in a few Japanese commercials featuring the game. You can view one of them to the right, and see the other ones here and here. It features early level design, graphics and enemies, including the third unused tile left in the final game.
|Prototype||Super Mario Bros. (World 2-1)|
This is part of World 2-1 from Super Mario Bros., but with free-roaming Poison Mushrooms instead of Goombas. The Poison Mushrooms don't disappear when they hit Mario, unlike the final game. We can't see what level this is at this point in development, because the camera is zoomed in too far.
Unlike in the final game, the graphics of the Poison Mushroom are unique, possibly because they are in the place of the Goomba graphics.
|Prototype||Final (World 6-2)|
This appears to be an early version of World 6-2.
|Prototype||Final (World 5-4)|
This level, from what we can see in the short footage of it, is the same as World 5-4 in the final game, except in the version of the level there is a Podoboo right after the first pillar.
|Prototype||Final (World 4-3 and World C-2)|
This part seems to be an earlier version of a part of World 4-3 or World C-2.
|Prototype||Final (World 4-3)|
This part seems to be an earlier version of a part of World 4-3.
Mario seems to start at odd positions at the left of the screen, possibly suggesting they developers used a debug tool to start Mario partway through the level. Or maybe these were separate areas and the developers had Mario start higher up than usual.
|Prototype||Super Mario Bros.|
This level, from what we can see in the short footage of it, is the same as World 8-1 in Super Mario Bros..
Screenshots in Manual
Some of the screenshots in the manual show level design differences. All of the gameplay screenshots (which are all set in overworld levels) use the third unused tile left in the final game.
In the early version, the block above the second mushroom-in-a-row contained something and the multi-coin block to the right of the stairs did not exist. In fact, they might be the same block.
In the early version, the hard blocks were brick blocks instead, the middle pipe was one tile further to the left, the ? block row had two less blocks and the top-right block row had less blocks to the left and more blocks to the right of the adjacent pipe.
