So i got a garou mvs cart dirt cheap , but there is a distortion to some of the soundeffects/music and some sounds just fine.
Where do i begin to troubleshoot this?
I have cleaned the contact so thats not it.
This probably isn't it but I would also clean your volume potentiometer and make sure it is set at 20%-30% and no more. Neo Geo likes to clip/distort a lot of shit once you go past that depending upon your setup. Usually it is high pitched sound effects from my experience.
