Hello, I finally find a MV1FZ board in very good condition. Battery is OK. Looking at the glue on the caps, they might be originals ones. Voltage was check on the convenient testing pad : 5,11V. I've played, everyday, one run until the end of the second level. So far, ten days of playing. Last...

I will buy one, is there a prefered model who is working best with the multi ?

Today result in slot 1 : -First try, sound corruption (crackling) at startup in Axel F module.

Volts between 5,11 and 5,12 on cart slot 1, probed in game between pin 1 and pin 30. No cart inserted. Neo Multi in cart slot 2. Metal Slug 3, music drop in level 2, first try.
