Popeye: Fixed background in popeyej, popeyejo & popeyebl. popeyej does not run on the exact same hardware as sky skipper & was the basis for the popeyebl set. Fixed horizontal and vertical scroll register behaviour in popeye. Change function names from the game name to the hardware id the functionality was first used in. [smf]
