I purchased a sf2ww pcb a couple years ago. I was having an issue with the image “jittering/shaking” when any horizontal scrolling took place. I sent out the board to a fellow member to be tested(and possibly an a-01 replaced)since this is my only cps1 game, he said the A board was ok but the B and C boards were having issues. I’ve since converted the pcb to daimakaimura and since there is a lot more horizontal scrolling its quite noticeable and I’d really like to find the issue. There is also some slight glitching of the background colors when I move the character(about every other step he takes). I’ve reflowed the b-17 custom on the C board a couple times and haven’t seen any improvement. I’ve tested continuity from xsel on the b-17 all the way to pin 69 on the a-01. Anyone seen this issue? I couldn’t find any posts describing this behavior. I know it’s difficult without having a working set to swap boards between but does anyone have any ideas on any areas to look at?
