New Version 1.1 with improved ambient sounds, several different crowd sounds for foul balls and a new set of custom bunt sounds.
Download the folder called sounds at the link below and copy it over your sounds folder in documents/outoftheparkdevelopments/ootpbaseball20 (works with ootp19 also). You may want to make a copy of your original sounds folder first, in case you want to roll back to original sounds.
