Compatible Cabinets
This is the list of compatible cabinets that can be used with this adapter:
Important: This adapter does not connect the -5V power rail which is not present in Capcom’s 1942 / Vulgus wiring harness. Games that require -5V may not run.
Button and Switch Layout:
In most circumstances this adapter will work as intended with your cabinet without any modifications. Problems may occur in a modified cabinet, or with games that require more than 2 buttons and more than one coin switch present.
If the button order is wrong you may need to swap the wires going to the buttons behind the control panel.
If game can’t be coined up, say in a case where only COIN2 switch is wired in the cabinet, and the game only supports the COIN1 switch, you may need to swap the coin wires on the harness or potentially jumper them together to get the game to coin up.
