yup! it looked like bad contact on the output pins of FL12 I just reflowed it and the right direction is working properly now. Thank you for the suggestion; that was an easy fix.The SMD Murata filters are a common issue on these boards, they lose contact from pads simply handling/flexing the PCB.
It seems the only problem now is the settings not saving.
I should note that I don't have the object board converted, I'm still using the normal SWS97 object board so sprites are garbled, but that is to be expected.
@SnakeGrunger You have a converted object board right? Try the last ROMs but with the KeyCus removed. let us know how it looks.
