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 3 buttons.

Some SNK game cabinets use different button mappings. Games that use 2 buttons may use JAMMA buttons 1 and 2 (Ikari Warriors), or buttons 2 and 3 (Alpha Mission and others). Also, games that use rotary joysticks may not work correctly with JAMMA games. If the button order is wrong you may need to swap the wires going to the buttons behind the control panel.
