You want Super Mario World updated, play the GBA port. They fixed Yoshi's and Luigi's spirtes, gave Luigi different abilities with Yoshi, and gives you a reason to collect Dragon Coins.

The GBA port modernizes other stuff too. Save anywhere, it has a list of all of the stages so that you can figure out where you want to exit too, getting hurt with a cape or fire flower downgrades you to Super Mario instead of all the way to normal, and saving holds over your number of extra lives.
Of course, if the n3DS version has save states like the Wii U one, the latter point is fairly moot.
