Quoted from TheLaw:
Not really no...what am i missing?
verified on a few different peoples machines that there is some distortion coming from the cabinet speaker output. Seems like it may not be limited to Star Wars, but is a base system code update that was made to Spike II games a while back, and so far we've found it to come from a batman 66, and Aerosmith. have not confirmed any other games at this point as we have not tested. I have rolled back to version .91 to confirm the distortion does not exist on that code version, and see it reappear when upgrading to the latest versions.
Also, I believe it may have been introduced in version 1.01 for Star Wars, but i do not have any earlier versions other than .91 to confirm. It is very subtle distortion, will be more noticeable depending on your ears and what you have your volume levels set to.
