The buttons are quite good, yet a bit hard. Guess what, they are exactly 24mm in diameter, perfect for Sanwa buttons.
He is my Jamma adapter for the trackballs:

Adding the missing components made the third player work !
Adding the missing D4701AC, the A472J resistor and shunting the filters:
And BAM ! the third player works !
