Hey! I was considering using a short audio clip from Mario 64 in my game  (Piranha Plant's Lullaby to be exact). Would this be okay to include? Thanks!   

Also tagging on because I have a similar question, I was thinking about using a short sound effect from melee (falcon kick...). No worries if not, I can probably make do / try and find a substitute. Thanks!

I don't know the legalities, sorry. Seems fine but don't trust me on that.

Okay no worries, thanks for the answer Otto :)
