Not sure if i am reading this right. So i just hit the service button for 4 seconds and dont need to dip any switches?



FREE GAME MODE. This mode is entered by holding the SERVICE CREDIT switch closed for more than four seconds. If fitted, the start

button lamps light and remain lit. The credit display shows 99. Pressing a start button will then start a free game, or a two player start button

will start a two player game. The Free Game Mode remains in operation until the host game is switched off.

Looks like your start buttons need to also be wired to the credit board (as well as the game board), and the credit board may need to have dip switches set for "Separate Mech Mode".
