Wario Land II but it's Super Mario Bros.

This Wario Land II ROM hack recreates the 1st level of Super Mario Bros., better known as World 1-1. This required a lot of retexturing, which only applies to the terrain (Wario and the enemies remain the same). Colours are the same as the NES game since the WL2 editor seemingly allows nearly any RGB value. Because of retexturing, now the intro graphics are messed up, but that doesn’t really matter.
