So, yesterday I added a Black Hole and Black Knight 2000 to the collection. Today have a pungent odor coming out of the arcade. Problem is, none of the games seem to have the offending odor coming out of the head or cabinet. Smells are obviously hard to convey because they are both captive to their location and subjective to the person who is smelling them. So, here is my best description: sometimes smells like cigarettes, sometimes smells like a burning ballast from a fluorescent light, not burning wire or a burning PCB. Any thoughts of where to start? Are either of these platforms known to have issues?
