Triple Play 99 PC Codes

This is what I've found by translating the PSX Tp99 codes into PC button patterns:
 
HOLD 1, 2, 3, 4 in gameplay to make codes work (Microsoft SW):
 
Commercial: Left, A, Right, C
Story: Up, X, Right, C
Trivia: Down, B, Right, C
Nickname Game: C, Right, A, Left
Weather Comment: B, Down, X, Up
Home Run Swing (700-1000 feet, doesn't work in HRD): X, A, X, C, B, A, Left, Right
Crowd - Aww!: B, Down, Down, B
Crowd - Light Cheer: X, B, B, X
Crowd - Loud Cheer: A, Left, Left, A
Crowd - Boo!!: C, Right, Right, C
 
I have no idea how these would work on the Gravis Gamepad (I don't own one) but I know that:
A=Button 1
B=Button 2
C=Button 3
X=Button 4
