There is a hidden copyright message at the beginning of the ROM at 0x00010:
ALIEN3...NINTENDO ENTERTAINMENT SYSTEM.PROGRAMMED BY DARYL BOWERS FOR PROBE SOFTWARE.CHECKSUM FOR ROMS:
There are no checksum checks in the ROM in any form. The routine to display the string was likely removed from the final version.
More unused text stored near the main game menu text and data may be found at 0x14766: "High Scores" and "ONE TWO". Most likely it was planned to be used in completely unimplemented in the final release "High Scores" table screen.
There are two different level types in the final version: "MISSION" and "GUARDIAN", which is stands for regular levels and a boss levels accordingly. But the level type names list contains two more strings, unused in the final version, stored at 0x1497C: "MAYHEM" and "RESCUE".
