Just received my pinball magic and as it is my first Capcom pin I´m wondering about some strange noise:
It happens during attract mode (maybe also during gameplay but not noticeable there) and has a regular pattern-its audible every 5 seconds on the speakers.
It is not related to the lamp matrix action nor to any changing content on the DMD.
It is independant of the volume setting

hard to hear on the video at 0:02, 0:07, 0:12,...its more dominant in real
Seems all the ferrites are in place. I guess it is all of the original ones, also tried 2 additional ones on the bottom connections on the soundboard without any change.
I assume all the caps on the boards are still the old original ones.
Is it something like a heartbeat from the CPU as it happens so regularly?
Anyone knows some details?
Is it just on my game or is it something normal on CAPCOM games?
My OCD does not like it, therefore I want to figure out the origin and try to solve it
