This is an update to Szemigi’s SMB4 The Undiscovered Zones. The hack is really well done, though it could have received some changes. This patch changes some stuff, such as making backgrounds in worlds more uniform and being less innovative in design, but more in line with SMB1 and SMB2j. Certain levels were also changed from “World 9-esque” Underwater into other settings. 5-3 is a custom level by Jeansowaty. Credits go to Szemigi for the original, ALXR for GreatEd and Jeansowaty for making this add-on.
