Pro Sport Hockey is your typical hockey sports game. Very reminiscent of similar hockey games at the time.
Sound Test#
The Japanese version, USA Ice Hockey in FC, contains a hidden sound test, triggered by holding Start + Select and resetting the game. This was disabled in Pro Sport Hockey, but the sound test is still accessible by using the Game Genie code IEKNZYYO and resetting the game.
