Well, there is one other option you have that could be beneficial if you want the propeller suit. There is currently a mod being made for nsmbds by me and a few others that will serve as a base for hacks to be made off of. Some major things it includes are:
-Propeller Suit
-Three up Moons
-Mega and triple blocks
-Physical checkpoints
-Support for multicheckpoint levels with physical checkpoints
-Makes all duplicate tilesets and backgrounds have their own file
-Shyguys (Blue, Red, Yellow, Green, Purple and Black)
-Ninjis
-Ice snake blocks
-Ring controller (Allows parakoopas, coins, boos, lavabubbles and amps to move in rings)
-Liquid wave controller (Can be used to make water, lava and poison waves)

There is a lot more that I havent mentioned. The released project should be posted here as an xdelta soon and the code will be uploaded to a github repo when its polished and annotated properly. For now though you can try builds of it as I post them every few days on the nsmbc discord server. I plan on dropping a build that includes the propeller suit later today
