As weird as an 8-bit style promotional DSiWare game made for a high-end next-gen game is, the weirdest thing about Dark Void Zero is definitely the Jimmy Fallon connection. According to the fake history Capcom and Other Ocean concocted for the DSiWare game, a young Fallon won a contest in the '80s and won both placement in the fictional game and the only known copy of the title, which Capcom "tracked down" to port to DSiWare (and now iPhone and PC, as well). We assumed it was just a desperate celebrity endorsement on the part of Capcom, but the truth is actually even weirder.
Other Ocean's Mike Mika thought up the "contest winner" angle to make the game seem more authentic, but decided that having someone well-known win the prize would make it even more identifiable. Speaking to GameSetWatch, Mika said "So, in this case, we worked on a game a while ago with Jimmy Fallon back with a company I was working for before Other Ocean. He's an incredibly smart guy who knows a lot about games. He knows a lot about computer engineering. And he had this game that he wanted to get made that was actually fantastic."
