The test switch is different on both, running from pin 15 for standard JAMMA and pin M for MV2F. Speaker out, though, is pins 10 and L for both, so it should be functional, using the same pinouts for the joystick, power, and buttons from start to D. So, you should be able to play most boards just without test and service switches with no re-wiring, which in most cases is no big deal, as JAMMA boards usually control options like difficulty through their dip switches.
