What happens if you score more than 99 points in volleyball?

Question

Some stages in Here Comes Niko! have a volleyball minigame with a 2 digit score counter on the side. What happens if you get a score above 99?

Answer 1

The score counter for volleyball maxes out at 99.

Interestingly though, your save file tracks your volleyball high scores past the 100 mark, even if it isn't shown in-game.
