While Mario isn't the focus of the fangame, I still need a Mario so I don't have to resort to using official voice clips which could get me in trouble (I'm already pushing the big N's buttons by using their game assets). I'm looking for someone who can mimic Charles Martinet's Mario voice.
For your audition, just do typical Mario stuff like the average sounds you'd hear in the original SM64 (and include an example of speech).
