2 Ship 2 Harkinian, another unofficial PC port of Zelda: Majora's Mask is out now

I think it is a play on the sequel to fast and furious (2 fast 2 furious)

The first "2" probably indicates that it's a sequel. "Ship" probably refers to the developers, "Harbour Masters" who made "Ship of Harkinian", the PC port of Ocarina of Time. The second "2" (I'm not too sure on this) might again, refer to it being a sequel, and "Harkinian" is likely taken from "King Harkinian" from the old Zelda CD-i games.
