Sonic CD's Hidden Message

Sonic CD’s original piracy check would bring unwitting pirates to a strange screen if it failed. The screen had some weirdly distorted images of Sonic with what appears to be an old man face along with the message “Fun if infinite with Sega Enterprises” signed by Majin. Majin can be translated as “devil” in English, and the screen had some pretty creepy music playing in the background along with an ominous laugh. Perhaps this was SEGA’s way of scaring pirates out of their pirating ways. You can still access the screen on a legit copy by entering specific sound test codes. So, what's the main point for all of this in Sonic CD?
