When repairing the Strikers 1999 game board, the inputs are as follows:

Player 1 U/D/L/R goes through RC2 (Resistor/Capacitor network SIP) Player 2 U/D/L/R goes through RC5

Player 1 controls (U/D/L/R and Button 1/2/3) go through U42 (74HCT244) Player 2 controls (U/D/L/R and Button 1/2/3) go through U43 (74HCT244)
