At offset 0x058327 in an unheadered US ROM, some leftover text from the SNES version of The Hunt For Red October can be found.
IN NOVEMBER OF 1984, SHORTLY BEFORE GORBACHEV CAME TO POWER, A TYPHOON- CLASS SOVIET SUB SURFACED JUST SOUTH OF THE GRAND BANKS. IT THEN SANK IN DEEP WATER, APPARENTLY SUFFERING A RADIATION PROBLEM. UNCONFIRMED REPORTS INDICATED SOME OF THE CREW WERE RESCUED. BUT ACCORDING TO REPEATED STATEMENTS BY BOTH SOVIET AND AMERICAN GOVERNMENTS, NOTHING OF WHAT YOU ARE ABOUT TO SEE... ...EVER HAPPENED.
The same leftover text can be found at a different offset in the SNES Tom & Jerry game and the SNES Beethoven game, both released earlier the same year.
