Well, that was able to replace the effects, but it has some major differences/problems, one of them being that the final smash freezes the game.
This is what I'm using:

EDIT: I just found out the final smash freezing is happening with my hack too, even though it worked fine long ago. Possibly it's something wrong with the new brawlex clone engine. That being said, the hack of yours still had some differences, such as the downair being sort of a stall in midair.
