This a progressive difficulty kaizo hack...be ready
Pay attention to not only the levels, the King's and peach wont stop talking. have a good time
SMB3 does NOT have in level information so if you're having trouble try looking at the coins and see if they can help.
SMB3 is not as fine tuned as Super Mario World so creating a save state at the start of each world and only the start ;) (just in case) is something I would do. This hack shouldn't crash but you can't save in SMB3 so its a just in case factor.
