How to access the TEST/Setup Menu on the XX-in-1 Multigame PCB

This applies to ALL XX-in-1 Multigame JAMMA PCBs (19-in-1, 39-in-1, 48-in-1, & 60-in-1).
To access the TEST/Setup Mode, press and hold the cabinet TEST Switch in the ON position and then power on the board. Once the board begins to boot up in the TEST mode then release the TEST switch. If the cabinet TEST Switch is not installed or unavailable, set DIP SW 3 – BIT 4 on the XX-in-1 PCB to the ON position (This is the blue set of switches located on the PCB), then power up the board.
After any changes are made on the setup/settings page(s), press the PLAYER 1 START Button prior to leaving that page and going on to the next (or shutting off the board). When you do this you should see 'SAVED SETUP OK' message after the Player 1 START button is pushed.
Once all changes are made and properly saved, to exit simply power off the board. Set DIP SW 3 - BIT 4 back to the OFF position if used to access the TEST menu.
