Theroy! nintendo dosn't want a free super mario maker floating out there (not just for legal resons) but thay maybe be working on super mario maker 3d....ummmmmmm..... i only hope
for example the guy who recreated super mario maker (smm) that was illegal... but if you make a smm clone and don't use anything mario related and use your own sprites and/or sb's srites your fine
not technical... aslong you name it somthig else and/or you give credit to owner and/or it's part of a leaning experince that's ok, but if just take a f-zero game and copy the code line for line then it copyright
Me attempt to replublish an if it dosn't work then copy all of the code paste it on a new program the plubish it... it will give you a key write it down and post it this should take no more than 5 to 10 mins
