Title: Mk1 in SF2 cab
Post by: matrix00 on January 05, 2012, 11:54:32 pm

I am shaping my sf2 hyper fighter with mk1 everything works but I get no audio.

Any ideas why no audio?

Do you have the sound board for MK1 as well? Or just the game PCB?

Looks like this and connects to the main PCB with a ribbon cable.

Is the sound board wired properly?

Make sure the ribbon cable RED end is plugged into pin 1 on each board. Do you get the BONG on boot up ?

MK is one of those boards that needs -5V (I think).  Are you getting -5V?

I ordered the sound pot. Which I did not have I am hoping that fixes the no sound issue.
