The HOL sight that you listed states the programmer of the Pocoman game as being Hannover Fist. Hannover Fist was the name of some software pirates who sold pirated Amiga and C-64 games and software in the late 80's and early 90's. I used to see them at HamFest's here in Michigan all the time. This must have been a pirated version of the game that HOL had. What does your original disk say?
