Piracy Message

WINNERS DON'T MAKE COPY!

There's a security check at 0x0014CA that checks the values at four memory locations (0x0006E4, 0x0006EA, 0x0006EE, 0x0006F2) to make sure their values match against hard-coded values. If they don't, you'll be shown this snarky screen, obviously parodying the ugly FBI "Winners Don't Use Drugs" screen of arcade games from the 90's.

Developer Credits

Among the text strings is a list of developers. This string is not referenced anywhere in the code, making it normally inaccessible. The last line is Japanese for "Don't Copy!" The text is fully formatted to appear on-screen, but the "Don't copy" line implies it is never meant to be seen in-game, and would only be seen by someone poking in the data (like a game pirate).
