Interesting. I have an Amiga, but I don't think I have any kind of Pac-Man for it.
I think that Deluxe pacman is currently listed as public domain, so you can easily get it from aminet or Amiga ftp. There is AGA and OCS/ECS version. The same author also programmed galaga deluxe for the Amiga, which is also impressive! Both are really fun and deserve to be played!
