I just remembered this bizarre Pac-Man hack that turned up in a few locations in my hometown when I was a kid. It was Pac-Man, but the Pac-Man sprite was replaced by a picture of Popeye's head. I can't remember for sure if anything else had been changed. I think the sounds may have been tweaked. I'm pretty sure Pac-Man still appeared during the intermissions.
I vaguely remember the marquee having amateurish pictures of a Popeye head and ghosts on it. I also seem to remember it being less fun than real Pac-Man for some reason, so I was always disappointed when places had this hack instead of the regular game.
Has anybody else ever seen this Pac-hack? Is a cab photo or ROM available anywhere? I'd like to see it again after all this time.
