This...this is not very good. There's no stage selects or bosses, two stages are missing, and balloons and genies don't appear. (Genies are replaced with basketball guys) There also is a different introduction, title screen, ending, and most music, and not a "Job Well Done" screen.
Otherwise, it's good, though. Like Super Mario World 64, they seem to have got most of the basic gameplay and enemies down.
