What if the Super Mario World Star World map had an actual level tileset? Well here is your answer! This is a tileset my friend Kojimkj (credits to him for making the tileset) made and I asked if I can port it to SMBX, so uh yeah, here it is! If this is used, please credit the both of us.
A very neat and nice-to-have tileset. I did notice that there's a duplicate of "block-79.png" called "block.79.png". Very nice work regardless, though!
