The original Japanese version of Gimmick contains a unique anti-piracy response where, if the opening cutscene is tampered with, the player will not be able to access the secret final level and it will instead cut to a black screen saying "BLACK HOLE" in reference to the game Atlantis no Nazo. Contrary to popular belief, this was not intended as an anti-piracy method, but rather a failed attempt by game designer Tomomi Sakae to prevent his name from being removed from the opening credits. This trigger was neatly edited around its intended purpose, and was eventually removed in the Scandinavian release of the game, though Sakae's name was reinstated as an unused line of intro text.
