I've been watching your runs on N64 and noticed you fly through the play screens after each down, in addition to flipping through the end of the quarters fairly quickly. For some reason, I am unable to do this. Is this just practice or is there a way to actually implement this?

I would love to know the answer to this as well

I figured it out which in turn helped me nab the WR in both categories. In-between play selection, you press up+a+b+z all at once.
