There are no tools for SNES or NES that I know of that wouldn't require you to code everything from scratch. GB Studio has been a tremendous help in creating this game. Without it it wouldn't have been possible! :O
You can check a fork of gb studio that add nes compatibility. Its called bb studio: https://github.com/michel-iwaniec/bb-studio
Also check Nesmaker. Is a commercial software, but is very intuitive. https://www.thenew8bitheroes.com/
