yeh it is very noticeable on that machine. For some reason, it doesnt seem to ghost so much on some data east/sega games anywhere as much on some williams/bally and gottlieb titles. I have had a very mixed result with ghosting on the various machines I have added lots of LEDS too.
you are spot on marty about what u have said about so many machines having so many variances. pain in the bum, but the only way to tell is to keep playing around with different Leds.
