New Super Mario Bros. Wii is a side-scrolling platform developed by Nintendo EAD and released in November 2009. The game was announced at E3 2009, and from the early videos and screens, Kirby64 was able to notice various beta differences:
In the screen with Mario in the pinguin-suit we can see an area that was originally going to be world 3-1, but it was later removed. The ice structure has a different design in the final version, with a more blue color and snow on top of the ice.
Some more info on the beta differences can be found at Mario Wiki:
In the E3 2009 demo, after players go through the boss door, they all fall from the top of the screen and into the boss room, as the initial Larry and Morton videos showed. This was just like in the original New Super Mario Bros., where the player also enters the Bowser Jr. battles the same way. In the final version, the players are already on the ground when the boss room loads up.
Kab-ombs, Mr. Blizzards, Stretches and Bowser Statues were meant to appear but they were cut out as soon as the game was released.
Also, LucaPM noticed a unused file in the NSMB Wii code, called “test_lift.arc”. As we can read at Rusted Logic, it is a graphic file, a stretched grey block.
Thanks to Kirby64 and LucaPM for the contributions!
