I think it would be cool to remake NSMBWii in SMW and I know you can make make custom power-ups, but is there anything you can think of that you cant make. I only want to recreate world 1. I am thinking that the first level with the rotating balls(for lack of better words) in the ground would be a problem. And 1-2 has those crytal platforms that move up and down. Is there anything else? And can you solve these problems?
you could swap some of the sprites of any moving sprites already in the game and just make them look like they were from New Super Mario Bros Wii
