WIP:New Super Mario Bros./Unused Graphics
The World 1 map has a unseen platform beneath the cannon.
The World 3 map has a bush hidden underneath the first grassy island.
Early Graphics Leftovers
These used World Map graphics are actually early versions of graphics found in level tilesets.
Small bush 1
Small bush 2
The world map textures were apparently never updated, but the tilesets were. "Small bush 2" and "large bush" can be seen in various pre-release materials. The size difference of the "large bush" may be due to memory limitations in the world map.
World 6 Map
[world 6 map uses tiles from unused mountain tileset]
World 4 Map Cave
The cave texture used in the World 4 map depicts an early version of the "near" cave background with grass added to the top. The background can also can be seen in prerelease materials.
