MVS Street Hoops Sound Issue

Hi.

I was just wondering about my copy of Street Hoops. I am currently piaying it on a revolver SG. The Mobo I am using is MV-1C, there is an awful lot of cracking sound in the back ground music. I tried cleaning the cart and the mobo but I still get the same problem, even after a "heavy" cleaning. Do I have a defective cart?

On the 1 slot board I used to have I would get a cracking noise when the headphone port was turned up, I dont know if that helps but you could try turning your headphone port all the way down and adjusting the audio properly with the speaker volume adjustment
