Figured out a way to export SMM3DS levels to wii u version with a modded system for both. for thos that are curious about how you need 3DS Level manager or OCDM found on GBATemp and then you need FTPIIU for file access to save data...
Post
part 2 and then go to your 3DS And pick level list and then export ur level to wiiu format than u must go to ftp app on pc or phone then make a empty level on smm and save and replace its course data main and subworld with the new one and then thats it
