Here’s a bit of weirdness: why has there never been a portable version of the Punch-Out!! series?

Sure, there’s been other boxing games on the Game Boy and its successors, but never Nintendo’s flagship punchfest. I know the franchise was essentially dead from 1994 until 2009, but the Game Boy was in its prime in the early to mid-1990s; that would’ve been the perfect time. The NES game used special mappers to handle those larger-than-life sprites, but I’m sure the whiz kids at Nintendo could’ve pulled off a similar feat with the lil’ green-and-black wonder. Hell, even a straight port would’ve been great! C’mon, who wouldn’t have wanted to beat the shit out of King Hippo during long car trips?!
