WIP:New Super Mario Bros. 2
World Map Diamonds
Like in New Super Mario Bros. Wii, the World Maps have 3D diamonds that mark the path spots, but they aren't visible in-game.
New Super Mario Bros. Leftovers
Early World Map Path
NSMB Seesaw Lift
The Seesaw Lift model, obj_lift_seesaw.bcres, contains a copy of the Seesaw Lift texture from New Super Mario Bros.. It doesn't fit the current model.
The European demo version contains graphics for USK, CERA, PEGI, Portuguese PEGI and ESRB ratings, but only the standard PEGI rating graphic is used.
Blue Block Shards
xxxx Blue Blocks have shard graphics which appear if they are destroyed, but destroying them isn't possible without hacking.
Gold Ring Tracks
Several music tracks in the game have accompanying accompanying "sparkly sound" tracks meant to play when a Gold Ring is in effect but are used for places that don't have Gold Rings in them, and thus are never heard. It is not known whether these were meant to be used, or are just a result of the developers being thorough when creating the audio assets.
