So, about the usage of the Ballade Cracker sound...

[Goomba98]

The Ballade Cracker's explosion sound is used for a lot more things than just the Ballade Cracker in MM8BDM. I bring this up because, if I'm not mistaken, I'm pretty sure that sound is just supposed to be an NES recreation of the explosion sound from the game Boy MM games, so the usage of it with things not from the GB games like the Party Ball doesn't make much sense. I think those things should use mm3expl.wav instead. (The only one that may make sense to keep is when a Count Bomb explodes, since those first appeared in Mega Man III.)

for the party balls, they where never in an NES game being in super famicom, playstation and sega saturn

But it wasn't in a GB game either, and since this game prioritizes NES-based things, I think it should use the MM3 sound.

This was taken into consideration for v6a and several props were changed as a result. Thanks for pointing this out!
